Fast, Reliable Windows & Doors Across Crestline
Window and door work in Crestline isn’t like work an hour below on the 215. At 4,500 feet in the San Bernardino Mountains, your home has to stand up to snow loads, freeze-thaw cycles, and CAL FIRE’s fire-hardening rules all at once. Most Crestline homes were built between the 1940s and 1960s as summer cabins, which means what’s behind those walls rarely matches what’s on the plans. We’ve been opening up those walls long enough to know what lives back there. If you’re looking at Windows & Doors work in Crestline, call Tom Barrett at (877) 610-1318. We’ll walk the property, talk through what’s actually there, and give you a written estimate before anything moves.

Why Barrett & Sons Construction Is Crestline’s Preferred Windows & Doors Company
Tom Barrett started Barrett & Sons in 1998, and he runs it with his sons on-site most days. You won’t get a franchise dispatcher. You’ll get Tom’s name on the contract, Tom’s phone number, and Tom coming back if something isn’t right. That’s the 90-Day Done Right Promise, and it’s written on every job we do in Crestline, not buried in fine print.
Crestline homeowners call us because we already know what the county inspector is going to look at before we open a wall. We know that a 1950s cabin off Highway 138 near Lake Gregory almost never has engineered headers above its windows. We know the roads up here narrow quickly and material delivery means smaller trucks or multiple trips. And we know that a window quote from a flatland contractor rarely survives contact with a Crestline rough-in. We price for what’s actually here.
Every crew member who carries the Barrett & Sons name is background-checked and uniformed. When you see our truck on your street off Waters Drive or near Lake Gregory Drive, it’s someone who’s supposed to be there. And if you call our office at (877) 610-1318 at 2 a.m. because a window shattered in a winter storm, a live person answers. Not a voicemail box. Not an out-of-state call center.
Tom publishes his name, his address, and his license number. Look it up before you sign anything. Ask anyone on your street, or check the license yourself. We stand by the work because we live twenty minutes away and want to see you at the hardware store on Saturday without crossing to the other aisle.
Our Windows & Doors Services in Crestline
Impact Windows & Doors
Impact windows and doors in Crestline have to do two jobs that most Southern California contractors never think about together. They have to hold up under snow loads and they have to resist ember intrusion during fire season. A standard dual-pane window from a big-box store handles neither. We install impact-rated units from PGT and CGI that are tested for both structural load and fire hardening. For a Crestline cabin, the typical scope runs $8,000-$25,000, and the final number depends on how many openings you have and what the rough-in inspection reveals behind the existing frames.

Window Replacement
Window replacement in Crestline usually starts with a surprise. We pull the old single-pane sash out of a 1960s A-frame and find undersized framing, dry rot from years of snowmelt, or no flashing at all. That’s normal up here. We handle it by writing a change order before we do the extra work, so you approve the number in writing before a single nail moves. A full window replacement in Crestline typically runs $4,500-$15,000. You’ll get a written line-item scope, not a phone number and a shrug.

Door Installation
Exterior doors in Crestline take a beating. Freeze-thaw cycles warp cheap frames. Embers find their way under worn thresholds. And a lot of older cabins have hollow-core interior doors where an insulated, properly weather-stripped exterior door should be. We install steel and fiberglass entry doors with ember-resistant vents where code requires them, and we flash every opening so snowmelt doesn’t end up weeping behind your siding. Door installation is part of our Windows & Doors service, and the price is always in writing before we start.

Window Installation
New window installation in Crestline is as much about the rough opening as it is about the glass. If you’re adding windows to a 1940s cabin, we check the wall to see if it’s load-bearing, whether the header is sized for snow load, and whether the opening needs shear reinforcement before the inspector arrives. We pull the permit, we meet the inspector, and we don’t cover anything up until it’s signed off. That’s not optional up here. A failed inspection on a mountain lot means another trip up Highway 18 or Highway 138, another frozen day, another delay.

Trusted Brands We Service in Crestline
We install and service windows and doors from Simonton, Ply Gem, and PGT. These are brands you can look up and verify, not mystery units off a van. For Crestline homes, we lean toward Simonton for thermal performance in cold winters and PGT for impact-rated applications where fire-hardening and wind loads matter. If you already have one of these brands installed and something’s failed, we can match the line and service it. We keep common parts in our Inland Empire yard and dispatch to Crestline from there, so turnaround on parts doesn’t require a month of phone calls.
Common Windows & Doors Problems We See in Crestline Homes
- Snowmelt rot behind windows. A 1960s cabin gets a window replacement without flash tape or proper layering. The first winter, snow melts off the roof, runs down the siding, and weeps behind the window frame. Six months later the subfloor is soft and the drywall is stained. We fix the flash, then we write the mold remediation as a separate, approved change order.
- Warped patio door frames after one winter. Inexpensive sliding glass doors installed without engineered snow-load reinforcement twist during the first freeze-thaw cycle. The door sticks, the lock stops lining up, and the frame pulls away from the studs. Crestline lots demand a different install than flatland neighborhoods.
- Unpermitted window widening on load-bearing walls. Someone cut a bigger opening for a view of Lake Gregory and didn’t pull a permit. Now the wall sags, and the inspector gets involved. We end up doing a structural retrofit with a properly sized header, and it costs triple what the original permit would have.
- Drafty single-pane windows in year-round homes. A lot of Crestline cabins were built for summer use only. The windows are single-pane wood sash with no thermal break. When the cabin becomes a full-time residence, heating bills spike and condensation ices up on the interior glass every January morning. We replace these with dual-pane units and re-insulate the rough openings as part of the job.
Pricing for Windows & Doors in Crestline, CA
Here’s what you should expect for window and door work in Crestline. These are line-item ranges for typical mountain homes in the 92325 ZIP code. Your exact number depends on the condition of your rough openings, the permit requirements on your specific lot, and how many units you’re replacing.
| Service | Crestline Price Range |
|---|---|
| Impact Window Installation | $8,000 - $25,000 |
| Window Replacement | $4,500 - $15,000 |
What moves the number? First is the rough-in. If the framing behind your old windows is water-damaged or undersized for snow load, that changes the scope. Second is fire-hardening requirements. CAL FIRE rules for the High Fire Hazard Severity Zone may require ember-resistant vents, tempered glass, or specific frame materials. Third is access. Steep lots off Lake Gregory Drive or narrow roads off Highway 138 often mean smaller trucks, more trips, and more labor. We write all of this into a line-item estimate before we begin, and any change gets a written change order with your signature on it first. Call (877) 610-1318 for a free estimate. We’ll walk the property and tell you exactly what you’re looking at.

FAQs - Windows & Doors in Crestline
Yes, if you’re changing the opening size, the answer is always yes. Any structural change to an exterior wall in Crestline requires a county permit, and that’s a good thing - the same applies to Home Additions & ADU in Crestline. The inspector works for you, not for us. If you’re doing a like-for-like window swap without changing the opening, the permit requirement depends on the specific scope and the county’s current guidelines. We pull permits on every eligible job and get the inspection signed before we close up any wall. Call (877) 610-1318 and we’ll tell you what your specific project needs.
Expect rough-in problems. That’s the honest answer. Most 1950s Crestline cabins have inadequate headers, no flashing, minimal insulation, and framing that was never designed for snow load. We find water damage around window openings more often than not, because snowmelt has been working its way in for 60-plus years. The way we handle it is simple: inspection first, then a written change order with a specific price if we find something that changes the scope. You approve it in writing before we do the work. You’ll never get a surprise invoice at the end. Call (877) 610-1318 to schedule a walkthrough.
We can, but there are days when we can’t get work done safely, and we’ll tell you that up front. Crestline winters mean road closures off Highway 18 and Highway 138, icy switchbacks, and site conditions that slow everything down. We plan Crestline winter work with buffer days and know the mountain routes well enough to schedule material deliveries for the mornings when the roads are clear. If a storm shuts things down for a day or two, we adjust the schedule and keep you informed. We’d rather lose a day than put a crew member or your home at risk. The permit clock may pause during weather closures, and we handle that with the county. Call (877) 610-1318 if you’re planning winter work and want to talk through timing.
Yes. Crestline sits in a High Fire Hazard Severity Zone, so CAL FIRE’s fire-hardening rules apply. Exterior doors in new or remodeled work often need to be solid-core, and any vented areas including foundation vents and attic openings may require ember-resistant mesh screens. Certain window frames and glazing are required in high-exposure areas. The exact requirements depend on your lot, your structure, and your project scope. We work with the county inspector to make sure your windows and doors meet both fire-hardening and snow-load requirements before sign-off. Call (877) 610-1318 for a free estimate, and we’ll talk through what applies to your home.
We don’t leave a punch list. That’s the short answer. After a multi-unit window replacement, Tom Barrett walks the job with you and you point out anything that isn’t done to your satisfaction. If it’s a warranted issue, we fix it under the 90-Day Done Right Promise. If it’s a touch-up you’d like done differently, we’ll write it up and take care of it. The important part is that the walkthrough happens before we call the job complete, and nothing gets left as a “we’ll come back for that” handshake. It’s in writing, like everything else we do.
How a Dual-Code Problem Changes Your Window Quote
Crestline sits at roughly 4,500 feet in the San Bernardino Mountains. That means two codes apply to your window and door work simultaneously. The first is snow load. Window and door openings must be framed and headed to carry the weight of snow on the roof plus the force transferred through the walls. The second is fire hardening. CAL FIRE’s rules for the High Fire Hazard Severity Zone require ember-resistant construction, specific venting, and exterior materials that don’t behave like kindling in a wind-driven ember shower. No flatland contractor working an hour below on the 215 deals with both of these at once. We do, and we’ve been doing it long enough that it’s built into how we price, how we frame, and how we sequence the work. On a steep lot off Highway 138 near Lake Gregory, our crew replaced a 1950s A-frame’s original single-pane windows with impact-rated dual-pane units and installed a new steel entry door with ember-resistant vents. The rough-in revealed undersized, water-damaged framing around the door opening, so we wrote a change order for a new load-bearing header, got approval in writing, and had the county inspector sign off before we closed the wall.
The point is this: in Crestline, a window replacement is rarely just a window replacement. It’s a structural job, a fire-safety job, and a permit job. We handle all three, and we show you the paper for every dollar of it.
