Fast, Reliable Windows & Doors Across Upland
Window and door work in Upland runs $4,500-$25,000 depending on scope, with impact-rated systems on the higher end and standard replacements on the lower. If you live in the 91784 foothills or the 91786 flats, the honest answer is that your ZIP code changes what the job involves before the first unit gets ordered. We’ve been doing this since 1998, and we answer our own phone at (877) 610-1318 when you call.
Most Upland homeowners we meet have already been through the phone-quote game: a national outfit gives one number, then the crew shows up and the price moves. That doesn’t happen with Barrett & Sons. Tom Barrett puts his name, his address, and his license number on every contract. You can look it up before you sign. Every scope change arrives as a written change order before work proceeds. If it’s not in writing, it doesn’t exist.
Why Barrett & Sons Construction Is Upland’s Preferred Windows & Doors Company
We’re owner-operated, and Tom Barrett or one of his sons is on-site most days in Upland. Not a dispatcher, not a rotating cast of strangers. The crew members carrying our name are background-checked and uniformed on every visit. Ask anyone on your street, or look up the license number yourself. We live twenty minutes away, which means if something’s wrong after we finish, we want to know about it.
Our Windows & Doors work across Upland comes with the 90-Day Done Right Promise written on every contract: if it isn’t done right, one call brings Tom back. We pull permits and pass inspections on every eligible job, because the last contractor most of our customers used told them permits were optional. They’re not. The permit inspector works for you, not for me, and that’s why I like him.
The other thing that separates us in Upland: we know the hillside lots, the Santa Ana wind corridors, and the fault-zone paperwork that flatland contractors never see coming. That local knowledge keeps your schedule honest and your price fixed in writing before anything gets ordered.
Our Windows & Doors Services in Upland
Window Installation
New window installation in Upland runs $4,500-$15,000 for a typical whole-home package, depending on unit count and whether we’re working with standard sizing or architectural glass. In south Upland’s 1950s-70s tract homes, original rough-in dimensions often don’t match modern frame sizing, which means we measure twice and order once. The older the home, the more the existing opening dictates what we can install without triggering framing work.

Door Installation
Entry door installation in Upland needs to account for the wind. North-facing exposures along the foothills in 91784 get hammered by Santa Ana down-slope gusts, and a door that’s not properly flashed and sealed will let water behind the frame within a season or two. We install with that exposure in mind, not just the manufacturer’s generic spec.

Window Replacement
Window replacement in Upland’s post-war housing stock is rarely a simple swap. On slab-on-grade tract homes from the 1960s, we routinely find hidden sill rot behind the stucco, where unsealed flashing from the original build let moisture sit for decades. You don’t see it until the old window comes out. When it shows up, you get a written change order before we touch the framing, not a surprise invoice at the end.

Impact Windows & Doors
Impact window installation in Upland runs $8,000-$25,000. This isn’t coastal hurricane protection; it’s about the wind-born debris and pressure differentials that Santa Ana events deliver to foothill homes. In 91784 especially, impact-rated glass and reinforced frames make sense for homes facing the mountain front, where the gusts come down without obstruction.

Trusted Brands We Service in Upland
We install Andersen and Marvin windows, and on the hardscape side we work with Belgard and Techo-Bloc when a project ties into exterior finishes. These are materials you can look up, not mystery brands off a van. We keep local parts stocked in our Inland Empire shop for Upland customers, which means when a warranty call happens, we’re not waiting on a shipment from the coast.
Common Windows & Doors Problems We See in Upland Homes
- Hidden sill rot behind stucco on Santa Ana-exposed walls. Unsealed window flashing on stucco homes in Upland’s wind corridors lets water intrude behind the finish. By the time a homeowner sees interior staining, the sill and subfloor damage is already done, and window replacement turns into structural repair.
- Rough openings shifted by alluvial-fan settlement in 91784. Hillside lots above the Euclid Avenue foothills sit on sloped alluvial deposits that move over decades. Original window and door rough openings drift out of square, meaning new units need header adjustments before they’ll seat properly.
- 1950s-70s tract homes with framing that fights modern window sizing. South Upland’s post-war builders used rough-in dimensions that don’t match today’s standard units. Ignoring that reality turns a straightforward replacement into load-bearing change orders and blown budgets.
- Custom architectural glass ordered before the fault-zone study is approved. In 91784, properties near the Cucamonga Fault may need Alquist-Priolo fault-rupture studies before permits clear. Contractors who order custom glass on day one find themselves sitting on thousands of dollars of material with no permit in sight. We sequence the paperwork first.
Pricing for Windows & Doors in Upland, CA
Window and door pricing in Upland breaks into two tiers. Standard replacements on flatland tract homes run $4,500-$15,000. Impact-rated systems on foothill homes run $8,000-$25,000.

| Service | Upland Price Range |
|---|---|
| Impact Window Installation | $8,000-$25,000 |

FAQs - Windows & Doors in Upland
Replacing windows with like-for-like units in existing openings typically doesn’t trigger an Alquist-Priolo fault-rupture study on its own. The study requirement lands when the project involves new structural openings, large additions, or ground-up work on parcels within or adjacent to the Cucamonga Fault study zone. That said, in 91784 we’ve seen permits stall because a window job was bundled with a structural wall change that crossed the threshold. Call (877) 610-1318 and we’ll tell you what your specific address faces before you order anything.
Santa Ana winds in Upland push down-slope from the San Gabriels into the foothill neighborhoods with enough force to drive rain and debris into unprotected frames. That means north-facing exposures in 91784 should use impact-rated or at minimum upgraded flashing and reinforced seals, while flatland homes in 91786 can often work with standard units. We spec the product for your exposure, not the same window we’d sell in Ontario. Call (877) 610-1318 for an in-person look.
Yes, but only if the original rough opening is structurally sound and the header can carry the new unit’s weight. South Upland’s slab-on-grade tract homes were framed for standard aluminum sliders, not heavy floor-to-ceiling architectural glass, and widening an opening usually requires an engineered header. We’ll tell you before you order the glass whether the opening can take it. An allowance that isn’t on paper is a surprise waiting for a date.
Custom impact sliding doors from Andersen or Marvin typically run 10-16 weeks from final sizing to delivery, and that’s before installation. In 91784’s fault-zone-adjacent parcels, the Alquist-Priolo study timeline can add 2-6 weeks of permitting before the glass order even starts. We sequence the paperwork first so your door doesn’t arrive before the permit clears. Call (877) 610-1318 to map the timeline for your address.
Yes. Widening a rough opening is structural work, and Upland building code requires a permit and inspection for any header modification. We pull the permit, schedule the inspection, and pass it before the job closes. The permit inspector works for you, not for me, and that’s why we like him. If a contractor tells you the permit is optional, that’s how the last job went wrong.
