Windows & Doors in Clovis, CA
Window installation in Clovis, CA usually costs $450-$1,400 per window depending on type, size, and frame material, with full-home replacement projects in north Clovis subdivisions commonly landing between $12,000 and $40,000. The dominant job here is replacing builder-grade aluminum and early dual-pane vinyl units installed between 1990 and 2015 that are now failing from San Joaquin Valley heat cycling. Call (509) 265-6387 for a written quote before any work starts.
Why Clovis Homes Are Different
Clovis grew fast. The master-planned communities north of Shaw and Herndon avenues, including Harlan Ranch in the northeast, were built out between roughly 1990 and 2015 by a handful of production builders who used the same window suppliers across entire subdivisions. That means the window problems here are strikingly uniform: seal failure in dual-pane units, aluminum frame oxidation, and hardware corrosion that shows up on every third or fourth house on a street once one home needs work.
The San Joaquin Valley climate does the damage. Sustained 100°F-112°F summer heat with extreme UV intensity degrades vinyl frames, oxidizes aluminum, and destroys the insulating gas fills inside dual-pane units far faster than coastal climates do. Then winter tule fog, dense and moisture-laden, finds every compromised seal and door threshold, causing interior condensation and frame rot even in homes that look fine from the outside. Old Town Clovis has a smaller stock of pre-1950 wood-frame homes that require entirely different weatherstripping and sash work than the stucco tracts around them.
Our Main Clovis Services
Clovis homeowners call us most about two jobs: replacing failing windows in builder-grade tracts, and swapping out worn entry and patio doors that no longer seal against the valley heat and fog. Both have dedicated Clovis pages.
Door Installation in Clovis
Door installation in Clovis means working with stucco tract homes where original doors were often undersized, poorly weatherstripped, and installed without proper flashing. We see threshold rot from winter tule fog and summer-cooled interiors, plus warped slabs that no longer close square. The job involves removing the old unit, inspecting and repairing the rough opening, and installing a properly shimmed, leveled door with new flashing and weatherstripping rated for sustained heat. Door Installation in Clovis covers the full process, including written pricing.

Window Replacement in Clovis
Window replacement in Clovis frequently means removing early dual-pane vinyl and aluminum units that have lost their insulating gas fills and failed their seals. In neighborhoods north of Herndon, the failure pattern is so consistent that we can often predict what we’ll find before we open the first wall. The work involves measuring each opening, ordering correctly sized replacements, and installing with proper flashing and insulation for the valley climate. Window Replacement in Clovis details the full scope and pricing.

Before
AfterWindow Installation in Clovis

Window installation in Clovis is dominated by full-unit replacement of builder-grade aluminum and early dual-pane vinyl windows installed between 1990 and 2015. The sustained summer heat west of the Sierra foothills causes seal failure and frame warping that makes repair increasingly pointless, which is why most of our Clovis work is full replacement rather than glass-only service. We install from eight manufacturer lines including PGT, CGI, and ES Windows, specified by the opening’s exposure and the homeowner’s performance requirements. Our Window Installation hub covers the national scope of this work.
Single & Double Hung Windows
Signs you need it
Upper sashes that drift down on their own, visible condensation between panes, or frames that have warped enough to make locking difficult.
What it costs in Clovis
Single hung windows run $450-$800 each, and double hung units run $600-$1,100 each installed, depending on size and glass package.
How we do it
We remove the old sash and frame, inspect the rough opening for rot or water damage, install the new unit with fresh flashing and insulation, and finish with interior and exterior trim.
Horizontal Roller Windows
Signs you need it
Rollers that grind or stick, tracks that have pulled away from the frame, or glass that rattles in the channel when the window is closed.
What it costs in Clovis
Horizontal roller window replacement runs $500-$1,200 per window in Clovis, with larger three-lite assemblies at the top of that range.
How we do it
We measure the existing opening, order a correctly sized replacement, remove the old frame, and set the new unit with new track hardware and weatherstripping.
What Window Installation Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Single hung window (installed) | $450-$800 |
| Double hung window (installed) | $600-$1,100 |
| Horizontal roller window (installed) | $500-$1,200 |
How long does window installation take in Clovis?
Most single-window replacements are done in a day. Full-home projects in Clovis tract homes typically take two to five working days, depending on the number of openings and whether we’re replacing stucco trim or working from the interior only. Call (509) 265-6387 for a written timeline.
Will my Clovis HOA require approval for window replacement?
Many north Clovis subdivisions have HOA architectural guidelines that require approval before window changes, especially if the exterior color or style changes. We can provide the specs and documentation your HOA will ask for. Call (509) 265-6387 to discuss your specific neighborhood.
Impact Windows & Doors in Clovis

Impact windows and doors in Clovis are specified less for hurricane risk and more for the valley’s sustained heat, UV exposure, and the growing frequency of high-wind events along the Sierra foothills. Impact-rated glazing from PGT and CGI carries a laminated interlayer that holds the glass together even when broken, which also reduces noise from nearby rail lines and highways. Clovis homeowners on larger lots and near open agricultural land choose impact products as much for dust and noise control as for impact resistance. Our Impact Windows & Doors hub covers the full product category.
Impact-Resistant Windows
Signs you need it
You want the strongest glazing available for a street-facing elevation, or you’re tired of the heat gain and noise coming through standard dual-pane units.
What it costs in Clovis
Impact-resistant windows run $800-$1,600 per opening in Clovis, with larger formats and higher design pressures at the upper end.
How we do it
We measure the opening, order the correct impact-rated unit from PGT or CGI with the required design pressure rating, and install with upgraded anchoring and flashing.
Single Hung Impact Windows
Signs you need it
You need impact protection on a home with a traditional single-hung look, common in Clovis tract elevations with a 50/50 or 60/40 sash split.
What it costs in Clovis
Single hung impact windows cost $700-$1,300 installed per window in Clovis, depending on size and glass package.
How we do it
We remove the old unit, inspect the rough opening, and install the impact-rated single hung with laminated glass and upgraded weatherstripping.
What Impact Windows & Doors Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Impact-resistant window (installed) | $800-$1,600 |
| Single hung impact window (installed) | $700-$1,300 |
| Impact sliding glass door (installed) | $2,500-$5,500 |
Do impact windows help with Clovis heat?
Yes. The laminated interlayer in impact glass blocks a significant portion of UV and reduces solar heat gain compared to standard dual-pane, which lowers cooling loads during valley summers. Call (509) 265-6387 for exact performance specs on PGT and CGI products.
Are impact windows required by code in Clovis?
Not generally. Clovis building codes do not mandate impact-rated glazing for standard residential construction, but some elevated or exposed sites benefit from the higher wind-load ratings. We’ll tell you honestly whether impact rating is necessary or optional for your opening. Call (509) 265-6387.
Energy-Efficient Windows in Clovis

Energy-efficient windows in Clovis are the single highest-ROI upgrade for homes built in the 1990-2015 tract wave, where builder-grade dual-pane units had the minimum Title 24 compliance of their era. A low-E coating plus argon gas fill cuts solar heat gain through west-facing elevations that bear the full afternoon valley sun. Sierra foothill exposure means Clovis windows get more direct sun than coastal California, so SHGC and U-factor choices matter more here. Our Energy-Efficient Windows hub explains the ratings and product lines.
Low-E & Argon Gas Glass
Signs you need it
Rooms that feel 10 degrees hotter than the rest of the house, fading furniture near west-facing windows, or cooling bills that spike every summer.
What it costs in Clovis
Low-E with argon gas runs $600-$1,400 per window installed in Clovis, depending on size and whether the frame is replaced or retained.
How we do it
We specify the correct low-E coating orientation for your elevation, order units with argon fill, and install with full frame sealing to eliminate air leakage.
ENERGY STAR Replacement Windows
Signs you need it
You’re replacing 1990s windows and want the documented energy performance to qualify for utility rebates or simply to cut the summer cooling load.
What it costs in Clovis
ENERGY STAR replacement windows run $500-$1,300 per window installed in Clovis, with upgraded frame materials above $1,000.
How we do it
We measure, specify the ENERGY STAR-rated product for the valley climate zone, and install with documented U-factor and SHGC values on the written quote.
What Energy-Efficient Windows Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Low-E + argon gas window (installed) | $600-$1,400 |
| ENERGY STAR replacement window (installed) | $500-$1,300 |
| Insulated laminated glass window (installed) | $700-$1,600 |
Which is more important in Clovis, U-factor or SHGC?
SHGC matters more because Clovis gets so much direct sun. A low SHGC blocks solar heat gain, which is what drives your air conditioner. U-factor still matters for winter fog and cold mornings. Call (509) 265-6387 for a written recommendation on your specific elevations.
Will energy-efficient windows pay for themselves in Clovis?
Most Clovis homeowners see measurable cooling savings in the first two to three summers after replacing 1990s builder-grade windows, especially on west and south elevations. The exact payback depends on your current units and utility rates. Call (509) 265-6387 for a written estimate.
Sliding & Patio Doors in Clovis

Sliding and patio doors in Clovis fail most often at the threshold and the weatherstripping, where winter tule fog and summer-cooled interiors create constant condensation cycles. Builder-grade aluminum sliders installed in the 1990s and 2000s oxidize at the track, bind on worn rollers, and let conditioned air escape through gaps that worsen every year. Replacement with a properly sealed modern unit from Therma-Tru or ES Windows changes both the comfort and the security of the back elevation. Our Sliding & Patio Doors hub covers the full range of door products.
Patio Doors
Signs you need it
The door sticks or grinds on the track, you can see daylight under the panel, or the frame shows visible oxidation and pitting from valley heat.
What it costs in Clovis
Standard patio door replacement runs $1,500-$3,200 in Clovis, with larger multi-panel sliders running $2,800-$5,000.
How we do it
We remove the old door, inspect the threshold and subfloor for rot from fog moisture, and install a new leveled door with fresh flashing and full-perimeter weatherstripping.
Sliding Glass Door Replacement
Signs you need it
The frame has corroded enough that the rollers can’t be adjusted, or the glass unit has failed and the frame isn’t worth saving.
What it costs in Clovis
Sliding glass door replacement runs $1,800-$4,500 in Clovis, depending on size, glass package, and whether the rough opening needs repair.
How we do it
We measure the existing opening, order a correctly sized replacement from ES Windows or Therma-Tru, and install with new rollers, track, and weatherstripping.
What Sliding & Patio Doors Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Standard patio door (installed) | $1,500-$3,200 |
| Sliding glass door replacement (installed) | $1,800-$4,500 |
| Impact sliding glass door (installed) | $2,500-$5,500 |
How long does a patio door replacement take in Clovis?
Most single patio door replacements are completed in one day, including removal, rough opening inspection, and installation. If we find threshold rot from fog moisture, the repair adds a day. Call (509) 265-6387 for a written timeline.
Can I replace just the sliding door panel instead of the whole frame?
Sometimes, if the frame is sound and the track isn’t corroded. In Clovis, we more often find frame oxidation that makes panel-only replacement a short-term fix. Call (509) 265-6387 and we’ll tell you what your specific door actually needs.
Impact Garage Doors in Clovis

Impact garage doors in Clovis are chosen not for hurricanes but for the high wind gusts that funnel along the Sierra foothills, especially on larger lots and exposed elevations in northeast Clovis. Laminated impact-rated panels also cut the heat gain into attached garages, which in valley summer means a garage that isn’t 120°F by 2 p.m. Homeowners with workshop or gym conversions in their garages choose impact doors for the noise and thermal isolation. Our Impact Garage Doors hub details the product lines and ratings.
Hurricane-Rated Garage Doors
Signs you need it
You have an exposed elevation, a detached garage with no thermal buffer, or you want the strongest wind-load rating available for the opening.
What it costs in Clovis
Hurricane-rated garage doors run $4,000-$9,000 installed in Clovis, depending on size, track system, and opener integration.
How we do it
We measure the opening, specify the correct wind-load rating for your exposure, and install the impact-rated door with reinforced tracks and upgraded anchoring.
Garage Door Replacement
Signs you need it
The existing door has bent panels, rusted tracks, or broken springs on a unit too old to justify repeated repairs.
What it costs in Clovis
Standard garage door replacement runs $1,200-$3,500 in Clovis, with insulated and impact-rated options at $3,000-$9,000.
How we do it
We remove the old door and hardware, install the new door with fresh tracks and springs, and test the full cycle including the opener’s force settings.
What Impact Garage Doors Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Standard garage door replacement (installed) | $1,200-$3,500 |
| Energy-efficient garage door (installed) | $1,800-$4,500 |
| Hurricane-rated garage door (installed) | $4,000-$9,000 |
Do impact garage doors need special openers in Clovis?
Most impact-rated doors work with standard openers, but the added weight of laminated panels often requires adjusting the opener’s force settings or upgrading to a heavier-duty motor. We specify the correct opener pairing on every written quote. Call (509) 265-6387.
Will an impact garage door keep my garage cooler in Clovis summers?
Yes. Impact-rated panels have an insulating core that reduces heat transfer compared to standard steel doors, and the added mass slows temperature swings. The effect is most noticeable on south-facing garages. Call (509) 265-6387 for exact panel specs.
Custom & Geometric Windows in Clovis

Custom and geometric windows in Clovis come up most often in two situations: renovations to Old Town Clovis wood-frame homes where standard sizes don’t fit the existing rough openings, and new additions in older neighborhoods where owners want something more interesting than the tract-standard rectangles. The valley’s heat means custom shapes still need proper low-E coatings and gas fills to stay comfortable. We specify custom units through CWS and ES Windows, which have the fabrication flexibility for radius tops, trapezoids, and oversized fixed panes. Our Custom & Geometric Windows hub covers the fabrication process.
Geometric & Shaped Windows
Signs you need it
Your home has a non-standard opening, an unusual architectural feature, or you want a specific shape that isn’t available in an off-the-shelf unit.
What it costs in Clovis
Geometric and shaped windows run $800-$2,500 each in Clovis, depending on shape complexity, size, and glass package.
How we do it
We template the opening, work with CWS or ES Windows to fabricate the exact shape, and install with the same flashing and sealing standards as a standard window.
Arched & Curved Windows
Signs you need it
You have an arched rough opening from original construction, or you want to add an architectural focal point that a square window can’t provide.
What it costs in Clovis
Arched and curved windows run $1,000-$3,000 each in Clovis, with radius-top and full-arch fabrication at the upper end.
How we do it
We measure the radius precisely, order a fabricated curved-top unit, and install it with custom trim matched to the existing interior and exterior profiles.
What Custom & Geometric Windows Costs in Clovis
| Item | Typical range in Clovis |
|---|---|
| Geometric or shaped window (installed) | $800-$2,500 |
| Arched or curved window (installed) | $1,000-$3,000 |
| Oversized custom opening (installed) | $1,500-$4,000 |
Can you match the style of my existing Clovis windows?
Yes. We match frame color, grid pattern, and glass type to your existing elevation, including the specific profile styles common in Clovis tract homes and Old Town wood-frame houses. Call (509) 265-6387 to describe what you need.
How long does a custom window take in Clovis?
Fabrication typically takes four to eight weeks after the measured survey is approved, depending on the manufacturer’s schedule and the complexity of the shape. Installation itself is usually a one-day job. Call (509) 265-6387 for a written timeline.
