Window & Door Replacement in Central Texas
Energy-efficient replacement windows and doors for homes across Waco, Temple, Georgetown, Round Rock, Austin, and 18 surrounding communities. Glacier Home Exteriors is your locally owned, authorized dealer and installer for Pella, Anlin, and Marvin windows — backed by a 5-year workmanship warranty and financing options to fit any budget.
Why Central Texas Homeowners Choose Glacier for Window Replacement
Your windows are the barrier between your family and Central Texas weather — 100-degree summers, spring hailstorms, and dramatic temperature swings that test every seal and pane. When windows fail, your energy bills climb, your comfort drops, and your home loses value. Glacier Home Exteriors specializes in replacing old, inefficient windows with premium, energy-efficient systems from Pella, Anlin, and Marvin that are engineered to perform in our demanding climate.
As a family-owned company led by Sean and Kristen Clifford, we treat every home like our own. We are not a franchise or a national chain with quotas to meet — we are your neighbors. Our certified installers follow manufacturer-specified installation procedures to the letter, because proper installation is just as important as the window itself. A poorly installed premium window will underperform a properly installed mid-range window every time.
We serve homeowners from Waco and the Heart of Texas region through the Temple-Belton corridor and into the northern Austin metro. Whether you need a single window replaced after storm damage or a full-home upgrade with 20+ windows, we deliver the same attention to detail, transparent pricing, and professional craftsmanship on every project.

Window Styles and Types: A Homeowner's Guide
Choosing the right window style for each room improves comfort, function, and aesthetics. Here is a breakdown of the most popular window types we install in Central Texas homes.
Double-Hung Windows
The most popular window style in Central Texas homes, double-hung windows feature two operable sashes that slide vertically. Both sashes tilt inward for easy cleaning from inside your home — no ladders needed for second-story windows. The independent top and bottom sashes give you precise ventilation control: open the top for warm air to escape, the bottom for a direct breeze, or both for maximum airflow.
Best for: Bedrooms, living rooms, and any room where easy cleaning and traditional aesthetics matter.
Casement Windows
Hinged on one side and operated with a crank handle, casement windows swing outward to catch breezes and direct airflow into your home. When closed, the sash presses tightly against the frame with a compression seal, making casement windows one of the most energy-efficient styles available. They provide an unobstructed view with no center rail and are easy to operate — even in hard-to-reach locations like over kitchen sinks.
Best for: Kitchens, bathrooms, and any location where maximum ventilation and an unobstructed view are priorities.
Sliding Windows
Sliding windows glide horizontally on smooth tracks, making them ideal for wide openings where vertical space is limited. Their low-profile frames maximize glass area for expansive views. Modern sliding windows feature heavy-duty rollers and interlocking rails for smooth operation and tight security. They are a popular choice for contemporary home designs and work well where exterior space is limited since no sash projects outward.
Best for: Wide openings, basement egress, above countertops, and rooms where exterior clearance is limited.
Picture Windows
Fixed, non-opening windows designed to frame views and flood rooms with natural light. Because they do not open, picture windows offer the best energy efficiency of any style — there are no seals that can wear out or allow air infiltration. They are commonly installed as a large center unit flanked by operable casement or double-hung windows on each side, giving you both the view and ventilation.
Best for: Living rooms, stairwells, and any space where maximizing light and views takes priority over ventilation.
Bay and Bow Windows
Bay windows project outward from your home in a three-panel configuration (typically a large center picture window flanked by casement or double-hung units at 30 or 45 degree angles). Bow windows use four or five panels in a gentle curve. Both create additional interior space — perfect for a window seat, reading nook, or display area — while adding dramatic architectural interest to your home exterior.
Best for: Living rooms, dining rooms, and master bedrooms where you want to create a focal point and add interior space.
Awning Windows
Hinged at the top and opening outward from the bottom, awning windows allow ventilation even during light rain since the open sash acts as a canopy. They are often installed higher on walls for privacy or paired below or above picture windows to add ventilation without sacrificing the view. The compression seal provides excellent weather resistance when closed.
Best for: Bathrooms, basements, and as companion windows above or below fixed picture windows.
Energy Efficiency for Central Texas: How Modern Windows Combat the Heat
Central Texas falls within IECC Climate Zone 2, one of the hottest residential climate zones in the United States. Our region experiences 2,500 to 3,000 cooling degree days annually, meaning your air conditioning system works hard for six to eight months of the year. Windows are responsible for 25 to 30 percent of residential heating and cooling energy use, making them the single most impactful upgrade you can make for energy efficiency.
Modern replacement windows combat Central Texas heat through three key technologies:

Low-E Glass Coatings
Microscopically thin metallic coatings reflect up to 70 percent of solar infrared heat while allowing visible light to pass through. Solar-control Low-E coatings (optimized for hot climates like ours) dramatically reduce heat gain through your windows without making rooms darker. This directly reduces air conditioning runtime and energy consumption.
Argon Gas Fill
The space between dual-pane glass is filled with argon, an inert gas that is denser than air and conducts less heat. Argon fill reduces heat transfer between the panes by approximately 30 percent compared to air-filled units. It also reduces convection currents between the panes, improving the overall insulating value (U-factor) of the window.
Advanced Frames
Modern vinyl and fiberglass frames contain multiple insulating chambers that prevent heat transfer through the frame itself. Unlike aluminum frames (common in older Texas homes), vinyl and fiberglass do not conduct heat. This eliminates the hot-to-the-touch frames that many Central Texas homeowners experience with their current windows.
ENERGY STAR Requirements for Climate Zone 2
To earn ENERGY STAR certification in our climate zone, windows must meet strict performance thresholds: a U-Factor of 0.40 or lower (measuring insulating ability) and a Solar Heat Gain Coefficient (SHGC) of 0.25 or lower (measuring how much solar heat passes through). All three brands we install — Pella, Anlin, and Marvin — offer product lines that meet or exceed these requirements. Anlin's SolarZone Elite glass package achieves some of the lowest SHGC values in the industry, making it a standout choice for Central Texas homeowners focused on minimizing cooling costs. Homeowners who upgrade from single-pane or non-Low-E double-pane windows to ENERGY STAR certified units typically save $200 to $400 per year on energy bills — with the greatest savings during our long, hot summers.
6 Signs You Need Window Replacement
Not sure if your windows need replacing? Here are the most common warning signs Central Texas homeowners should watch for.
Drafts Around Closed Windows
If you feel air movement near closed windows, the seals have failed. Drafty windows force your HVAC system to work harder, increasing energy bills and reducing comfort. In Central Texas summers, even small air leaks let humid, 100-degree air infiltrate your home.
Condensation Between Glass Panes
Fog or moisture between the panes of a double- or triple-pane window means the insulating gas seal has broken. Once the seal fails, the window loses its insulating value and cannot be repaired — the entire insulated glass unit must be replaced.
Difficulty Opening, Closing, or Locking
Windows that stick, jam, or will not lock properly are more than an inconvenience — they are a security risk and a potential safety hazard during emergencies. Warped frames, failed balances, and corroded hardware are common in older Central Texas homes.
Visible Frame Damage or Rot
Wood rot, cracked vinyl, corroded aluminum, or peeling paint on window frames indicates structural deterioration. Damaged frames cannot support the weight of the glass properly and allow water infiltration that can damage surrounding wall framing and insulation.
High Energy Bills
If your electric bills spike every summer despite a well-maintained HVAC system, your windows may be the culprit. Single-pane windows or older double-pane units without Low-E coatings allow significant solar heat gain, forcing your air conditioning to run constantly.
Excessive Outside Noise
If you can clearly hear traffic, neighbors, or lawn equipment through closed windows, your current windows lack adequate sound insulation. Modern dual-pane windows with argon gas fill can reduce exterior noise by 25 to 50 percent compared to single-pane glass.
Window Replacement Cost in Central Texas
Window replacement pricing varies by material and configuration. A typical 15-window project starts at $12,000. Vinyl windows are the most economical option. Fiberglass and wood-clad windows come at a premium. Actual costs depend on window size, style, glass package, and installation complexity.
Vinyl Windows
The most economical option for Central Texas homes. Zero maintenance, excellent insulation, and a wide range of styles. Best overall value for energy efficiency.
Fiberglass Windows
Premium durability with slim profiles that maximize glass area. Will not warp, rot, or corrode. Ideal for homeowners who want long-term performance without wood maintenance.
Wood-Clad Windows
Classic interior warmth with a weather-resistant exterior. The premium choice for luxury homes and custom architectural projects where aesthetics are the top priority.

Window Replacement FAQs for Central Texas Homeowners
How much do replacement windows cost in Central Texas?
Window replacement pricing depends on the frame material, glass package, window size, and installation complexity. A typical 15-window project starts at $12,000. Vinyl windows are the most economical option, while fiberglass and wood-clad windows come at a premium. Factors that affect cost include the number of stories (second-floor installations require more labor), whether structural modifications are needed (enlarging or reducing openings), the glass package selected (dual-pane Low-E vs. triple-pane), and the frame material. We provide detailed, itemized estimates so you can see exactly what you are paying for — no hidden fees or surprise charges. Contact us for a free consultation and personalized quote tailored to your home.
How much energy will new windows save in Texas?
Most Central Texas homeowners see a 10 to 20 percent reduction in heating and cooling costs after replacing single-pane or older double-pane windows with modern ENERGY STAR certified Low-E, argon-filled units. For a home with average monthly energy bills of $200 to $250, that translates to $200 to $400 in annual savings. The savings are particularly significant in our climate zone (IECC Zone 2) because cooling accounts for the majority of energy costs. Modern Low-E coatings reflect up to 70 percent of solar heat gain while still allowing visible light to pass through, meaning your air conditioner runs less without making your home dark. Argon gas fill between the panes adds insulating value equivalent to adding another pane of glass. Over a 20-year window lifespan, those annual savings add up to $4,000 to $8,000 — offsetting a significant portion of the replacement cost.
What window brands does Glacier Home Exteriors install?
We are authorized dealers and installers for three premium window brands: Pella, Anlin, and Marvin. Each brand serves different needs and budgets. Pella offers the widest range of styles and price points, from their value-oriented Encompass line to the premium Architect Series, in wood, fiberglass, and vinyl frames. Anlin specializes in premium vinyl windows engineered for extreme heat climates, with their SolarZone Elite glass package and an industry-leading true lifetime warranty that includes accidental glass breakage. Marvin crafts luxury wood and fiberglass windows with Ultrex fiberglass exteriors and warm wood interiors, ideal for custom homes and architectural projects. During your free consultation, we help you determine which brand and product line best fits your home, aesthetic preferences, performance requirements, and budget.
How long does a full-home window replacement take?
A full-home window replacement for a typical 3-bedroom home with 15 to 20 windows is usually completed in 1 to 3 days. Individual window installations take approximately 30 to 60 minutes each, depending on the window size, type, and any complications with the existing opening. We install from the exterior whenever possible to minimize disruption inside your home — in most cases, you will not need to move furniture or take down curtains. Larger projects, custom window configurations, or installations that require structural modifications to the openings may take additional time. We provide a detailed timeline during the estimate process so you know exactly what to expect. Our crews work efficiently without cutting corners, and we clean up thoroughly at the end of each workday.
Should I replace all my windows at once or in phases?
Replacing all your windows at once is the most cost-effective approach and delivers the best results. You benefit from lower per-window pricing, consistent energy performance throughout your home, uniform aesthetics from every angle, and a single installation disruption instead of multiple visits. However, we understand that a full-home replacement is a significant investment. If budget is a concern, we can help you prioritize which windows to replace first based on condition, energy impact, and visibility. South- and west-facing windows in Central Texas receive the most solar heat gain, so replacing those first delivers the biggest energy savings. We also offer financing through Enhancify with promotional no-interest terms for up to 24 months, which makes doing the full project at once more accessible for many homeowners.
What is Low-E glass and why does it matter in Central Texas?
Low-E (low-emissivity) glass has a microscopically thin metallic coating — thinner than a human hair — that reflects infrared heat energy. In Central Texas, where summer temperatures regularly exceed 100 degrees and cooling costs dominate energy bills, Low-E glass is essential. The coating reflects solar heat away from your home in summer, reducing heat gain through windows by up to 70 percent compared to clear glass. In winter, the same coating reflects interior heat back into your home. There are different types of Low-E coatings optimized for different climates: our region benefits most from solar-control Low-E (also called Low-E 366 or similar designations), which prioritizes blocking solar heat gain. All three of the brands we install — Pella, Anlin, and Marvin — offer advanced Low-E glass packages specifically designed for hot climates like ours. The coating is virtually invisible and does not noticeably change the appearance of your windows.
Do you offer financing for window replacement projects?
Yes. Through our financing partner Enhancify, we offer multiple financing options including promotional no-interest financing for up to 24 months on approved credit. You can check your rate with no impact to your credit score through a soft credit inquiry. Financing makes it possible to replace all your windows now and pay over time, which is often smarter than waiting because you start saving on energy costs immediately. Monthly payments for a typical full-home window replacement often run $150 to $300 per month — comparable to or less than the energy savings you gain from the new windows. During your estimate appointment, we can walk you through the financing options and help you find a plan that fits your budget. We believe every Central Texas homeowner deserves energy-efficient, comfortable windows regardless of whether they can pay the full amount upfront.
What is the difference between full-frame and insert (pocket) window replacement?
Full-frame replacement removes the entire existing window including the frame, trim, and sometimes the surrounding flashing, down to the rough opening in the wall. This allows us to inspect the structural framing for water damage or rot, add or improve insulation, install new flashing for weather protection, and ensure a perfect fit. Insert (pocket) replacement slides a new window unit into the existing frame, which is faster and less expensive but only works if the existing frame is in good condition and properly sized. In Central Texas, we recommend full-frame replacement for most projects because it delivers superior energy performance, allows us to address any hidden moisture damage (common in our humid climate), and results in a cleaner finished appearance. During your free inspection, we assess the condition of your existing frames and recommend the best approach for each window in your home.
Will new windows reduce outside noise in my home?
Yes, significantly. Modern dual-pane windows with argon gas fill reduce exterior noise by 25 to 50 percent compared to single-pane glass. The two panes of glass separated by the gas-filled space create a sound barrier that dampens vibrations from traffic, lawn equipment, barking dogs, and other neighborhood noise. For homes near busy roads, highways (I-35 runs through our entire service area), or commercial areas, we can recommend enhanced sound-reduction options including triple-pane glass, laminated glass (which has a sound-dampening interlayer similar to automotive windshields), or asymmetric glass configurations (where the inner and outer panes are different thicknesses to disrupt sound wave transmission). The improvement is immediately noticeable — most homeowners tell us the difference is dramatic from the moment we install the first window.
How do I know if my windows need to be replaced or just repaired?
Some window issues can be repaired, but replacement is typically more cost-effective when multiple problems are present or when the windows are more than 15 to 20 years old. Repairs make sense for isolated issues like a broken latch, torn screen, or single cracked pane on an otherwise sound window. Replacement is the better investment when you see condensation between the glass panes (seal failure), feel drafts with windows closed (weatherstripping failure), notice wood rot or frame deterioration, have difficulty operating the windows (warped frames or failed balances), or when your energy bills are consistently high despite a well-maintained HVAC system. As a general rule, if more than one-third of your windows need repair, full replacement is usually the more economical choice when you factor in the cumulative repair costs, improved energy efficiency, and increased home value. We provide honest assessments during our free inspections and will never recommend replacement if repair is the better option.
What warranty does Glacier Home Exteriors offer on window installations?
We stand behind our work with a comprehensive 5-year workmanship warranty that covers the installation itself — including the seal between the window and the wall opening, interior and exterior trim, flashing, and caulking. This warranty is in addition to the manufacturer warranties on the window products themselves, which range from limited lifetime (Pella and Marvin) to true lifetime including accidental glass breakage (Anlin). Our workmanship warranty means that if any installation-related issue arises — a leak around the window, trim separation, or any defect in our work — we will return and correct it at no charge. We are a locally owned, BBB Accredited company that has built our reputation on standing behind our work. Sean and Kristen Clifford personally guarantee every project we complete.
Are there tax credits or rebates available for new windows in Texas?
Yes. Under the federal Inflation Reduction Act (IRA) and the Energy Efficient Home Improvement Credit (Section 25C), homeowners can claim a tax credit of up to 30 percent of the cost of qualifying ENERGY STAR Most Efficient windows, up to a maximum of $600 per year for windows and skylights. To qualify, the windows must meet the ENERGY STAR Most Efficient criteria for our climate zone. All three brands we install offer qualifying products. Some local utility providers also offer rebates for energy-efficient home improvements — check with your electric provider (Oncor, Austin Energy, or your local co-op) for current programs. We recommend consulting with your tax professional about eligibility, and we provide the manufacturer certifications and receipts you need to file the credit. These incentives effectively reduce the net cost of your window replacement project.
