Front Door Replacement

Our Door Installation in San Jose makes front door replacement the single highest-impact upgrade you can make to a home’s curb appeal, security, and energy efficiency. Most front door replacements in San Jose run $1,200 to $2,800 installed depending on material, glass inserts, and hardware. Westlight Windows San Jose installs Therma-Tru fiberglass entry doors and Mr-Glass decorative glass units, and you’ll receive a written price before any work begins, so the number you approve is the number you pay.

Fiberglass vs. Wood Entry Doors

Fiberglass doors hold up better than wood in San Jose’s dry summers and damp winters, and they don’t warp or swell the way oak and mahogany can after a few rain seasons. We walk you through the trade-offs with specific Therma-Tru product lines so you’re choosing based on how the door performs, not just how it looks.

Security Hardware and Reinforced Frames

A new door is only as good as the frame around it. We inspect the rough opening, replace rotted jamb material when we find it, and set the strike plate and deadbolt so the lock engages fully. Homeowners in Alum Rock and Berryessa frequently tell us their old deadbolt barely caught the strike plate after years of settling.

Door Replacement

Door Replacement covers any existing door that’s failed, sagged, or stopped sealing, from a faded rear entry to a drafty side door. Most door replacements in San Jose run $500 to $2,400 depending on whether we’re replacing just the slab or the entire pre-hung unit including the frame. Westlight Windows San Jose carries eight manufacturer lines, so we match the right product to the job rather than forcing a generic door into an existing opening.

Slab vs. Pre-Hung Replacement

If your existing frame is square and solid, replacing just the slab can save real money. But once the jamb has rotted or the opening has shifted, a pre-hung door with a new frame is the only fix that lasts, and we’ll tell you which one applies before you spend a dollar.

When the Frame Goes Bad

San Jose’s older neighborhoods, especially around Naglee Park and Japantown, have door frames installed decades ago with little weatherproofing. We find rotted sills and open gaps behind the casing regularly, and correcting those before the new door goes in is what prevents a repeat repair in three years.

Sliding Glass Door Replacement

Sliding Glass Door Replacement is the fix for a door that sticks in its track, fogs between the glass panes, or lets a draft through even when closed. Replacement costs in San Jose typically run $1,600 to $3,400 installed depending on glass package, width, and whether the frame needs reconstruction. Westlight Windows San Jose installs PGT and ViewLux sliding glass doors with low-e glass (a thin coating that reflects heat back into the room in winter and out in summer), and we haul away the old unit.

Fogged Glass and Failed Seals

If condensation appears between the panes, the seal has failed and the glass is no longer insulating. Replacement is the only real fix, and we’ll spec the new glass package to match your home’s sun exposure, especially on south-facing and west-facing walls that catch the strongest San Jose afternoon heat.

Upgrading to Impact-Rated Glass

PGT’s impact-rated sliding doors are built for zones with high wind and flying debris, which matters for homes in the foothills and for anyone who wants a door that holds up better in a major storm. We’ll show you the difference in frame thickness and glass weight so you understand what you’re paying for.

Storm Door Installation

Storm Door Installation adds a second layer of protection to an existing entry door, improving ventilation in spring and blocking wind-driven rain in winter. Storm door installation in San Jose runs $380 to $900 installed for most standard door widths. Westlight Windows San Jose installs ViewLux and Mr-Glass storm doors with retractable screens, and we set the closer so the door doesn’t slam in the afternoon wind that funnels through the Santa Clara Valley.

Ventilation Without Losing Security

A storm door with a full-view retractable screen lets you leave the main door open for a cross-breeze while the storm door stays locked. That matters in San Jose’s shoulder seasons when the weather is mild enough to want air moving through the house.

Protecting Your Main Door Investment

If you’ve just replaced a front door, a storm door is what keeps rain off the finish and extends the life of the door’s weatherstripping. We’ll match the storm door to your existing hardware and paint finish so the pairing looks intentional, not bolted-on.

Sliding Glass Door Installation

Door Installation - Sunnyvale and beyond includes sliding glass door installation, a fresh-door install where no sliding door currently exists, such as a kitchen wall opening onto a backyard patio or a dining room that has never connected to the yard. Installation in San Jose runs $1,800 to $3,600 depending on opening width, structural header work, and glass package. Westlight Windows San Jose handles the full scope from framing to trim, with permits pulled and inspections passed when the opening requires it.

New Openings and Structural Headers

Cutting a new opening in a load-bearing wall requires a properly sized header, and we take that seriously. Owen Satterfield personally verifies header sizing and load path on every structural opening before the saw comes out.

Maximizing Your Backyard Connection

San Jose’s climate means your patio is usable most of the year, and a sliding glass door makes that connection effortless. We’ll talk through glass packages that keep heat gain down on west-facing walls and frame colors that work with stucco, board-and-batten, and mid-century exteriors.

Door Repair

Door Repair addresses a door that still has life in it but isn’t working the way it should, from a sticking slab to a deadbolt that no longer catches. Most door repairs in San Jose run $150 to $500 depending on whether we’re adjusting hinges, replacing weatherstripping, or re-hanging the slab. Westlight Windows San Jose offers a free second visit if a repair fails within the guarantee period, included automatically with no negotiating required.

Sticking, Sagging, and Misaligned Slabs

When a door scrapes the floor or won’t latch, the fix is usually hinge adjustment or a slight re-hang, not a new door. We’ll tell you honestly whether your door is worth repairing or whether replacement is the smarter money, and we’ll put that recommendation in writing.

Drafty Doors and Worn Weatherstripping

Feel air moving around the edges of your door? The weatherstripping has compressed or failed, and the fix is usually under $200. We replace door sweeps, jamb seals, and threshold gaskets with products sized to the actual gap, not generic strips that leave the same leak in place.

Exterior Door Installation

Exterior Door Installation covers every door that faces the outside of your San Jose home, including front entries, side doors, rear doors, and garage-to-house doors. Exterior door installation runs $700 to $2,800 installed depending on whether we’re replacing an entire pre-hung unit or just the slab. Westlight Windows San Jose installs Therma-Tru, Mr-Glass, and PGT exterior doors, and every job includes a written price before work starts, a committed arrival window, and a job site left cleaner than we found it.

Weatherproofing That Actually Holds Up

San Jose gets less rain than most of the Bay Area, but when storms hit, wind-driven rain finds every gap. We flash the rough opening, bed the threshold in sealant, and set the jamb so water sheds away from the home instead of pooling at the sill.

Garage-to-House and Side Entries

The door between your garage and your house is an exterior door by code, and it needs a fire rating and a self-closing hinge. We’ll make sure that door is compliant, sealed, and closes properly every time, which also keeps garage fumes and cold air from leaking into living space.

French Door Installation

Door Installation in Cupertino and throughout the area includes French door installation, which brings double-door light and access to a dining room, living room, or den, and it’s the most involved door project most homeowners take on. French door installation runs $2,000 to $4,000 installed depending on whether you’re replacing a slider, cutting a new opening, or swapping a window for doors. Westlight Windows San Jose installs ViewLux and Mr-Glass French doors and handles the structural work, flashing, interior trim, and hardware as a single cohesive job.

From Slider to French Doors

Replacing an old sliding glass door with French doors changes how a room feels, and the framing is often less intrusive than homeowners expect. We reuse the existing opening when possible, which keeps cost down and speeds the job up.

In-Swing vs. Out-Swing Configurations

In-swing French doors are traditional and work well in most San Jose floor plans, but an out-swing door saves interior floor space and seals tighter against wind pressure. We’ll show you the difference on-site and talk through which configuration works better for how you actually use the room.

Brands We Service

Westlight Windows San Jose installs products from eight manufacturer lines, and we’re genuinely familiar with the behavior of each. Therma-Tru fiberglass entry doors are our most-requested front door brand because their frames stay square through San Jose’s temperature swings and their finish options look like real wood without the maintenance. Mr-Glass decorative glass inserts let homeowners add leaded or etched glass to a Therma-Tru door without paying custom-shop prices.

PGT makes the impact-rated sliding glass doors and exterior doors we recommend for foothill homes and anyone who wants a door tested against high wind and flying debris. ViewLux builds clean modern storm doors and French doors with thin sightlines, which works well for mid-century and contemporary San Jose homes. Whether you have PGT, Therma-Tru, ViewLux, Mr-Glass, or any other make we carry, we can spec, order, and install it with the same written guarantee on the completed work.

Signs You Need a Pro Right Now

• Visible daylight around the door perimeter. If you can see light between the closed door and the jamb, the weatherstripping has failed or the slab has shifted. That gap is also where conditioned air leaks out of your home, driving up summer cooling costs in San Jose.
• The door scrapes the floor or won’t latch. A sagging slab means the hinges have worn or the frame has settled, and forcing the door closed puts stress on the latch and handle. This is usually repairable, but left alone it can damage the frame beyond repair.
• Condensation between double-pane glass. Failed seals are a signal that the glass has lost its insulating gas, and once the seal is gone, the door does not perform the way it should. Replacement glass or a new door is the only way to restore the thermal barrier.
• You feel a draft even when the door is closed. A draft means the weatherstripping has compressed or the threshold seal has cracked, and it usually worsens with each season. In San Jose’s winter months, a drafty door lowers room temperature enough to notice in your heating bill.
• Rot or cracking around the door frame. Soft wood, flaking paint, or visible cracks in the jamb indicate moisture has been getting where it shouldn’t. This is a structural issue, not a cosmetic one, and it should be inspected before the door itself fails.

Our Process, Step by Step

1. 1
   You call, a person answers. When you call (669) 333-7786, a live person in our office picks up and schedules a free estimate at a time that actually works for you. We don’t route calls to a call center or ask you to leave a message and hope.
2. 2
   We show up in the window we gave. Our technician arrives on time, in uniform, and completes a full walkthrough of the existing door, frame, and surrounding trim. We measure the rough opening, check the level and square of the frame, and note any structural work the job will require.
3. 3
   You get a written price before any work starts. We don’t give ballpark ranges over the phone and then revise the number when we arrive. The price we write down is the price you pay, and it includes materials, labor, permits when required, and haul-away.
4. 4
   We install the door and leave the site clean. Work is completed by background-checked, uniformed technicians who treat your home with care. We lay down floor protection, vacuum the work area, and haul away the old door, frame, and packaging before we hand you the written guarantee.
5. 5
   We come back if the work fails. Every job carries our 365-Day Done Right Promise in writing. If the installation is not right within the guarantee period, we return and correct it at no charge, no negotiating required.
