AfterFast, Reliable Windows & Doors Across Claremont
Window replacement in Claremont typically runs $4,500-$15,000, and impact window installation usually lands between $8,000-$25,000 depending on the number of openings and whether you’re north of Baseline Road, where Chapter 7A fire-safety code applies. Most Claremont jobs take 1-3 days once materials arrive, and the rough-in inspection is a standard part of how we work. We’re Barrett & Sons Construction, and Tom Barrett’s crews know Claremont’s older housing stock the way a mechanic knows a 20-year-old truck: we can tell you what’s behind the trim before we pull it. Call (877) 610-1318 for a free estimate, and you’ll get an answer from a real person, not a call center.
Claremont isn’t one housing market. It’s two. South of Foothill, you’ve got tidy 1950s and 60s ranch tract homes on slab foundations that have settled unevenly over expansive Pomona Valley clay. North of Foothill, up toward the Claremont Hills Wilderness Park, you’re in the San Gabriel Mountain front, inside a Very High Fire Hazard Severity Zone, and the City’s plan-check staff enforces Chapter 7A material lists like a drill sergeant. A window or door replacement that touches the building envelope is not a simple swap up there. It’s a permit-sensitive job with ember-resistance requirements most flatland contractors never confront. We know the difference because we do both.

Why Barrett & Sons Construction Is Claremont’s Preferred Windows & Doors Company
We’re not a franchise dispatching strangers. Barrett & Sons Construction has been owner-operated since 1998, and Tom Barrett’s sons run the crews. When a homeowner in Claremont calls, the person who answers is someone who has driven Foothill Boulevard, knows how the permitting counter at City Hall operates, and has likely worked on a home within a mile of yours. That’s the whole point. Local roots, on time, community first, accountable, loyal. We keep it that simple.
Our reputation in Claremont rests on one thing: we put every scope, every allowance, and every price change in writing. The last contractor most Claremont homeowners used told them permits were optional, or quoted one number on the phone and showed up with another. We don’t do that. Ever. Our crews are background-checked and uniformed, and every eligible job gets permits pulled and inspections signed. Ask anyone on your street, or look up the license number yourself. Tom publishes it.
We carry premium-brand depth because we won’t install materials you can’t look up. On Claremont window jobs, we’re talking Andersen and Marvin, not mystery brands off a van. On door systems, we spec for thermal performance and WUI compliance, not just curb appeal. And if something isn’t done right, the 90-Day Done Right Promise is written on every contract. One call brings Tom back. That’s the whole warranty, in plain English.
Our Windows & Doors Services in Claremont
Our Windows & Doors team handles the full range of replacement, new installation, and fire-safety upgrades for Claremont homes. The four services below cover roughly 90% of what we get called for in this city.
Window Installation
New window installation in Claremont runs the gamut from replacing a single failed window in a Claremont Village bungalow to full multi-opening retrofits on 1960s ranch homes near the 91711 ZIP. We strip the old trim, inspect the rough opening for rot and framing pull-away, and correct what we find before the new unit goes in. On homes built before 1950, that inspection isn’t optional. The original wax-paper water barriers behind stucco-over-wood-lath routinely fail, and you won’t know until the trim comes off.
Door Installation
Exterior doors in Claremont do double duty. They’re your primary thermal seal against 105°F summer heat, and on hillside homes inside the WUI zone, they’re part of a non-combustible exterior assembly. We install entry systems, French doors, and side-lite configurations, with attention to threshold sealing and jamb anchoring. A door that’s been settling for 30 years on expansive clay won’t swing true, and shimming it isn’t the answer. Reframing it is.
Window Replacement
Replacing windows in a 1920s Craftsman on Indian Hill Boulevard is not the same job as replacing windows in a 1970s rancher off Mills Avenue. The older home conceals knob-and-tube wiring in the wall cavities, undersized 2×4 framing that has pulled away from the king studs, and failed water barriers. We plan for this up front, with an allowance written into the contract for rough-in corrections. If we find something, you get a written change order before we touch it. Window replacement in Claremont: $4,500-$15,000 depending on count, material, and what the walls reveal.
Impact Windows & Doors
Claremont’s northern residential neighborhoods sit directly against the Claremont Hills Wilderness Park and the San Gabriel Mountain front, placing a significant portion of the city’s housing stock inside California’s Very High Fire Hazard Severity Zone. Chapter 7A of the California Building Code mandates ember-resistant vents and non-combustible exterior assemblies on any window or door replacement that touches the building envelope. Impact windows and doors, with WUI-rated framing and ember-resistant screens, aren’t a premium option north of Baseline Road. They’re the compliance path. We specify them, pull the permit, and have the plan-check staff sign off on the material list before we close up the walls. Impact window installation typically runs $8,000-$25,000 in Claremont.

Claremont’s Chapter 7A Reality: What Actually Changes on Your Window Job
Here’s what most window and door pages won’t tell you about Claremont. This city doesn’t just happen to have a fire zone. Claremont’s northern neighborhoods sit inside California’s Very High Fire Hazard Severity Zone, and Chapter 7A of the California Building Code mandates ember-resistant vents and non-combustible exterior assemblies on any window or door replacement touching the building envelope. That’s a compliance burden no flatland Pomona or Ontario contractor faces day to day. A contractor who routinely works in Pomona or Upland and tries to spec standard vinyl soffits or attic vents will get a correction notice before the first nail is driven. We’ve seen it happen. The City’s plan-check staff cross-references Cal Fire’s fire hazard mapping and enforces Chapter 7A material lists strictly.
For you, the homeowner, this means three practical things. First, your window replacement permit will specify materials by name, and you can’t swap them without a plan revision. Second, the inspection process is more rigorous: the rough-in inspection verifies that the window assembly, the flashing, and any adjacent vents are all WUI-listed. Third, the cost is higher than a flatland bid, but it isn’t optional. We build the WUI line items into the original quote, so you’re not surprised at the permit counter. An allowance that isn’t on paper is a surprise waiting for a date.
On a 1920s Craftsman on Indian Hill Boulevard north of Foothill, our crew pulled the original double-hung windows and found knob-and-tube wiring buried in the exterior wall cavities, undersized 2×4 framing that had pulled away from the king studs, and failed wax-paper water barriers. We wrote a change order for new rough-in wiring, sistered the load-bearing jambs, and switched to Kolbe ultra series wood windows with WUI-rated fiberglass frames and ember-resistant screens, then had the City’s plan-check staff sign off on the Chapter 7A material list before closing up the walls. That’s how this job goes in Claremont. We don’t pretend otherwise.
Trusted Brands We Service in Claremont
We install window and door systems from manufacturers whose specs you can pull up online before you even let us in the door. Andersen and Marvin on windows, Kolbe for WUI-rated wood and fiberglass options, and solid-core entry systems built for thermal performance and fire resistance. We don’t carry off-brand materials that disappear from warranty support in three years. If a Claremont homeowner wants to see the material list for their Chapter 7A permit, we hand it over. Brands like Techo-Bloc and Cambridge Pavers show up more on our hardscape work, but the principle is the same across every trade: named brands you can verify, or nothing.
Common Windows & Doors Problems We See in Claremont Homes
- Thermal bridging in 1910s-1940s homes. Original wood-framed windows in Craftsman and Spanish Colonial Revival homes near the Claremont Village leak air in summer. With Claremont routinely hitting 105°F, the energy loss through those windows is in the double digits. Replacement with modern insulated glass pays for itself fastest here.
- Correction notices on Chapter 7A violations. Vinyl soffits or standard attic vents spec’d by contractors used to working in Pomona get red-tagged in Claremont because they violate ember-resistance requirements. If your window job includes vent replacement, the materials have to be WUI-listed. We spec them from the start.
- Dry rot behind the trim. Failed waterproofing behind stucco-over-wood-lath on older exterior window surrounds results in dry rot around the rough opening. You won’t see it until the trim comes off. That’s why we write a rough-in allowance into every Claremont window replacement contract.
- Slab settlement on the valley floor. On 1950s and 60s ranch tract homes in the flatter parts of the 91711 ZIP, slab-on-grade foundation movement has thrown doors out of square and windows out of plumb. A new unit installed into an unsquared opening will bind and fail prematurely. Reframing the rough opening is part of the job.

|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
What moves the number is what’s behind the trim. Older homes on Indian Hill, College Avenue, or anywhere in the Village frequently need rough-in reframing, wiring corrections, and water barrier replacement. That work isn’t hidden: it’s an allowance written into the contract, and if we find it, you get a change order with a fixed price before we proceed. No surprises at the end. Call (877) 610-1318 and we’ll walk the job with you and write a line-item quote.

FAQs - Windows & Doors in Claremont
Only homes inside the designated Very High Fire Hazard Severity Zone, which generally covers Claremont’s northern residential neighborhoods against the San Gabriel Mountain front, are subject to Chapter 7A on window and door work. Homes south of Baseline in the flatland areas typically do not trigger Chapter 7A. The City’s plan-check staff makes the determination based on Cal Fire hazard mapping when you pull the permit. Call (877) 610-1318 and we can tell you whether your specific address falls inside the zone before you pay for anything.
The inspector verifies that the new window assembly, the flashing, and any adjacent vents or soffit materials are WUI-listed and match the approved Chapter 7A material list. They check the rough opening for proper anchoring and that any reframing was done to code. If the permit was approved with Andersen or Kolbe WUI-rated units, you can’t swap in a off-brand standard window at the last minute. That’s a correction notice waiting to happen. We stage the materials early so the inspector sees exactly what’s on the plan.
Yes, but it isn’t a window swap. The knob-and-tube wiring in the exterior wall cavity has to be addressed as part of the rough-in work. We write an allowance into the contract for wiring correction, and when we find what’s actually in the wall, you get a written change order with a fixed price for new rough-in wiring before we touch it. Then we reframe the opening, install the new WUI-rated units, and have the inspector sign off before closing the walls. It’s more work, but it’s the right work. Call (877) 610-1318 for an exact quote.
Because the vent didn’t meet Chapter 7A ember-resistance requirements. Claremont’s plan-check staff cross-references Cal Fire’s hazard mapping and enforces the material list strictly, and a standard vinyl attic vent on a home inside the WUI zone gets red-tagged. A contractor who does most of their work in Pomona or Upland can miss this entirely. We spec WUI-listed vents as part of any window or door job that touches the envelope, so the permit clears the first time.
You get a written document describing what we found, the scope of the reframing work, the materials we’ll use, and a fixed price for the correction. Nothing moves until you approve it. It’s exactly what we do when a 1950s ranch in the flatter parts of the 91711 ZIP reveals dry rot behind the old window trim. The change order becomes part of the contract record, and the final invoice matches the original scope plus the approved change order. That’s the whole system. Call (877) 610-1318 and we’ll talk you through it.
