Fast, Reliable Window Replacement Across Kentfield
Replacing windows in Kentfield means working with homes that sit under redwood canopies, on slopes, and in fog patterns most Bay Area towns don’t get. The job usually starts with a fogged pane or a sash that won’t stay up, and it ends with a written price, a permit- ready plan, and glass that actually fits the opening. We serve Kentfield directly, with crews who know the local housing stock and the Design Review Authority step that applies to many visible elevations. Call (817) 686-2228 to schedule a free estimate, and we’ll walk the project with you before anything goes on paper.

Why Meridian Windows & Doors Is Kentfield’s Preferred Window Replacement Company
Most Kentfield homeowners we meet have either dealt with a contractor who scoped the job from a phone photo or one who discovered the real problem only after the old window came out. Our approach is different because we write the scope from the actual opening, not from a guess. Elliot Vance, who leads Meridian Windows & Doors, holds every job to The Garrison Standard, the same operating discipline Garrison Partners has used since 2009: show up when promised, put the price in writing before work starts, and stand behind the result for a full year. That written guarantee is the 365-Day Done Right Promise, and it applies to every installation and repair we do in Kentfield.
Phones are answered by a live person around the clock, every day. If a window fails within the guarantee period, we return at no charge. No fine print about labor exclusions. No voicemail loop when you call to ask where the crew is. For Window Replacement in Kentfield, that discipline matters because the town’s older wood-frame homes have quirks you only catch by being on site: out-of-square rough openings, rotted jambs hiding behind trim, and fogged insulated glass units that indicate a failed sash rather than a simple glass swap.
Window Sash Replacement in Kentfield
Window Sash Replacement in Kentfield is the fix when the moving part of the window, the frame that holds the glass, has swollen, rotted, or sagged to the point that the unit won’t open, won’t close, or won’t seal. In Kentfield’s 1960s through 1980s wood-frame homes, years of valley fog and damp winters take a toll on original wood sashes. The wood absorbs moisture, the corners loosen, and the insulated glass unit inside eventually fails. Replacing just the glass in that situation solves nothing; the new pane sits in a sash that still leaks. A full sash replacement in Kentfield typically runs $450 – $900 per opening depending on sash material and whether the jamb needs rebuilding.
What Sash Replacement Involves
The old sash comes out, the jamb gets inspected for rot, and we rebuild any framing that has softened before setting the new sash. With thermally broken vinyl or composite sashes, the new unit seats tightly and operates without sticking. Most Kentfield sash jobs take one day per three to four openings once materials are fabricated.
When Homeowners Need It
Fogged glass, drafts you can feel at the sill, or a sash that drops when you open it are the usual signals. If the window still operates smoothly but the glass is cloudy, you may only need glass repair. If the operating frame itself has failed, sash replacement is the honest fix, and we’ll tell you which one applies before quoting.
Window Glass Repair in Kentfield
Window Glass Repair in Kentfield replaces the insulated glass unit, or IGU, when the seal has failed and moisture has gotten between the panes. In Kentfield, fog between the panes is a cold-season fact of life. Warm indoor air meets cool glass, condensation forms inside the failed seal, and the unit clouds over permanently. The repair removes the old IGU and installs a new low-E unit in the existing frame. The cost for a standard window glass repair in Kentfield runs $175 – $400 per pane, with larger or custom units pushing toward the top of that range.
Fogged Glass vs. Failed Sash
The critical step is determining whether the glass alone is the problem or the sash around it has also failed. We do not quote glass-only work until we’ve inspected the operating frame. A fogged IGU in a sound sash is a straightforward fix; a fogged IGU in a rotted sash is a sash replacement with new glass, and pricing it any other way produces a change order later.
Low-E Glass and Kentfield’s Mornings
Most Kentfield glass repairs spec low-E coated glass, a thin coating that reflects heat while letting light through. On fog- heavy mornings, that coating reduces interior condensation because the interior glass surface stays warmer. It is not a cure for failed seals, but it is the right glass for a town where moisture control on the inside matters as much as keeping weather outside.

Trusted Brands We Service in Kentfield
We spec and install products from PGT, CGI, and CWS, among eight manufacturer lines we carry. Kentfield homeowners don’t need us to push one brand; they need the right unit for a house under redwoods where thermal performance and condensation control matter more than storm-driven impact ratings. We keep local parts access fast for Kentfield customers and order direct from the manufacturer for custom sizes rather than forcing stock units into out-of-square openings. PGT and CGI units cover the thermal and structural needs of most Kentfield wood-frame homes, while Window Replacement projects on larger glass areas often spec CWS for its sightlines and frame strength.
Common Window Replacement Problems We See in Kentfield Homes
- Fogged insulated glass units in 1960s-1980s homes. The seal fails, moisture gets between the panes, and the only real fix is a new IGU. We see this constantly in Kentfield’s older wood-frame stock.
- Sagging sashes on original double-hung windows. Years of damp air and gravity loosen the corner joints, and the sash drops or won’t stay open. Sash replacement restores operation and seal.
- Out-of-square rough openings. Kentfield homes from the mid-century era rarely have perfectly square window pockets. Stock-size units get shimmed and caulked into gaps, which leaks air. Custom-fabricated units fit the actual opening and seal correctly.
- Design Review Authority delays. Replacements on visible elevations in Kentfield, especially in the Kent Woodlands architectural district, can require a DRA submittal before work starts. Contractors who ignore that step stall the project after the contract is signed.
Pricing for Window Replacement in Kentfield, CA
Most single-window replacements in Kentfield land between $700 and $1,400 installed, depending on unit size, frame material, and whether the opening requires custom fabrication. A full-frame replacement on a standard double-hung runs $900 – $1,400; an insert replacement that fits inside the existing frame runs $700 – $1,100. Sash-only work runs $450 – $900, and glass-only repair runs $175 – $400. What moves the number: custom sizing for out-of-square openings, jamb repair if rot is found, DRA submittal time on visible elevations, and the glass package you choose. Every Kentfield quote is written before work starts, and the price does not move at the door. Call (817) 686-2228 for a free estimate, and we’ll give you line-item numbers for your specific openings.

FAQs About Window Replacement in Kentfield
Yes, in many cases. Kentfield’s Design Review Authority must typically review replacements on visible elevations and within the Kent Woodlands architectural district, which adds a plan-submittal step before work can begin. Not every window requires it; interior-facing or rear elevations sometimes fall outside DRA review depending on scope. We check the applicable requirements for your property during the estimate and include any submittal time in the schedule, not after the contract is signed. Call (817) 686-2228 and we’ll confirm what applies to your house.
Most Kentfield window replacements run two to five weeks from signed contract to final inspection. The biggest variables are custom fabrication lead times, which run one to three weeks, and DRA submittal review when visible elevations require it. A glass-only repair can be done in a day once the unit is in hand. We’ll give you a written schedule that accounts for fabrication and review time, so the date doesn’t drift after you sign.
Your insulated glass unit’s seal has failed, and moisture has gotten between the two panes. Once the seal breaks, condensation from indoor air collects inside the unit and clouds permanently. The fix is a new IGU, not a wipe-down. In Kentfield, where valley fog and cool damp winters are normal, seal failure is the most common window problem we see in homes built from the 1960s through the 1980s.
Yes. Low-E glass has a thin coating that reflects heat while letting light through, which keeps the interior glass surface warmer on cool mornings. That warmth reduces interior condensation on the pane, which is the clammy feeling Kentfield homeowners describe in bedrooms on fog-season mornings. It won’t fix a failed seal, but it is the right glass package for a home under redwood canopy where moisture control matters year-round.
The two honest ones are rotted jamb repair discovered after the old window comes out and custom fabrication for out-of-square openings that a photo estimate missed. Kentfield’s older wood-frame homes frequently have both. We avoid those surprises by pricing from the actual opening during the estimate, not from a photo. Your written price includes the full scope, and if we find rot at that first visit, it’s in the quote before you sign. Call (817) 686-2228 for an exact quote, and we’ll mark every cost driver on paper.
