Fast, Reliable Impact Windows & Doors Across Palo Alto
Impact windows and doors in Palo Alto run $1,100-$3,400 per opening installed, with most full-home projects landing between $28,000 and $85,000 depending on product line and how many openings face the ARB. TruePane has been getting these installs through Palo Alto’s Architectural Review Board without rejected orders or stalled jobs because we file the packet ourselves and schedule around the review clock. Call (888) 635-0804 for a written line-item quote before you order anything.
We work across 94301 and the surrounding P
alo Alto neighborhoods regularly, from Professorville to Midtown to Crescent Park. Our crews know which product lines clear design review here, which hardware finishes hold up to morning marine-layer humidity, and which stile profiles the ARB staff will check with a ruler.
Why TruePane Windows & Doors Is Palo Alto’s Preferred Impact Windows & Doors Company
Palo Alto homeowners call us because we do not guess at the review process. Our Impact Windows & Doors team has pulled ARB pre-approvals on Professorville Craftsman bungalows, Colonial Revivals south of University Avenue, and 1950s ranchers near Midtown where owners want impact-rated replacements without triggering design-review objections. We know what the city’s planners look for because we have sat through those hearings and walked those packets through.
Dale Kessler founded TruePane in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. That applies as much to a tilt-turn unit in a Queen Anne as it does to a sliding impact door in a Palo Alto rancher. We hold to the Done Right Promise and The Keystone Standard on every job: both manufacturer warranty layers registered in writing, durations stated, before our truck leaves your driveway.
We are not the cheapest bid in Palo Alto. We are the company that answers the phone when something goes wrong six years after the install, and our live person picks up 24 hours a day, seven days a week. The homeowners who call us have often lived in their houses for twenty or thirty years and they intend to stay. They want one company, one crew, one standard.
Our Impact Windows & Doors Services in Palo Alto
Hurricane Impact Windows
Impact-rated windows for Palo Alto homes typically run $1,100-$2,400 per opening for vinyl or aluminum frames and $1,800-$3,400 for aluminum-clad wood. The real variable here is not the glass. It is whether your house sits in a design-review district where the ARB requires custom stile profiles and true divided lights. In Professorville, a standard vinyl impact window will get rejected before a permit is ever pulled. We spec the right line the first time and file the packet ourselves.

Impact Sliding Glass Doors
Impact sliding glass doors in Palo Alto run $4,200-$9,800 installed, with multi-slide units reaching $14,000 or more. Morning marine-layer humidity settling on east-facing frames generates condensation complaints unless the frame has a thermal break and the glazing is spec’d for diurnal swing. We quote manufacturer lines side by side on paper so you can see the thermal data, not just the brochure.

Impact Entry & French Doors
Impact-rated entry and French doors in Palo Alto run $5,500-$12,500 per opening, with custom wood French doors in design-review districts pushing toward $16,000. The ARB cares about door height, stile width, and finish color, not just glass ratings. We handle the submittal with photographs of the existing door and the proposed profile so review does not stall the calendar.

Impact Garage Doors
Impact garage doors for Palo Alto homes run $3,800-$8,200 installed, depending on sectional versus carriage-style. Older garages in the 94301 corridor often have non-standard framing that needs steel stiffeners before an impact-rated door will hang true. We check the opening before quoting, not after.

Trusted Brands We Service in Palo Alto
We are an authorized installer for more than a dozen manufacturer lines, and in Palo Alto we find ourselves quoting CGI, CWS, and ES Windows more than most. CGI impact windows clear ARB review when the exterior profile matches the original wood sightline, and CWS gives us a midrange aluminum-clad option with proper thermal breaks for east-facing walls that wake up wet. For Palo Alto’s older homes, we keep replacement hardware, weather-stripping, and glazing beads locally available so service calls do not wait on a factory backorder. If your current impact window is fogged, bowed, or binding, we can usually restore it without replacing the entire unit.
Common Impact Windows & Doors Problems We See in Palo Alto Homes
- ARB rejection of impact window orders that don’t match original wood profiles. This happens constantly to contractors who treat Palo Alto like Mountain View. The review board measures stile width and divided-light patterns, and if the replacement does not match the original 3¼-inch profile, the order is dead before it is placed. We pre-clear the product line with city staff before you pay a deposit.
- Fogged insulated glass from diurnal temperature swings. Palo Alto’s inland position means upper-80s afternoons collapsing to low-50s nights. That cycle flexes IGU seals more aggressively than coastal Bay Area weather, and argon leaks out slowly. The result is a fogged pane two or three years sooner than you would expect. We see it routinely in 94301 homes.
- Morning condensation on east-facing aluminum frames without thermal breaks. The marine layer settles here most summer mornings, and when it hits cold aluminum, water beads and runs where the frame meets the sash. Over time that causes interior paint damage and mold at the sill. The fix is a frame with a true thermal break, not a wider drip edge.
- Lead-paint complications on original single-pane wood sashes. Most Professorville and Midtown homes built before 1978 have lead paint on or around the original windows. Removal requires containment protocols, and skipping that step creates a liability no homeowner should accept. Our crews are trained on lead-safe work practices and build the prep time into the schedule.

FAQs - Impact Windows & Doors in Palo Alto
Yes. Any exterior window or door replacement on a pre-1940 home in the Professorville Historic District requires Architectural Review Board approval before installation. The ARB checks that the replacement matches the original material, stile profile, and divided-light pattern. A standard vinyl retrofit will not pass. We file the packet with photographs, manufacturer spec sheets, and profile drawings, and we schedule installation only after the approval letter is in hand. Call (888) 635-0804 to start the submittal.
Plan on four to six weeks for Professorville ARB review from the date of submittal to the approval letter. That clock runs on Palo Alto’s schedule, not ours, and it cannot be rushed. We stage materials off-site during the wait, complete lead-safe interior prep, and book the installation crew for the week after approval is expected. That way the job does not sit half-finished waiting on a committee. Call (888) 635-0804 and we will give you a week-by-week schedule before you sign.
No. Standard vinyl impact windows do not match the original wood sightlines of pre-1940 Professorville homes, and the ARB rejects them on profile alone. The board has rejected fiberglass windows for not matching the original 3¼-inch wood stile. The compliant options are custom wood or aluminum-clad wood units from lines like Sierra Pacific or Marvin with true divided lights. We spec the right product from the start so you do not pay for a rejected order. Call (888) 635-0804 for a compliant quote.
It is common in Palo Alto, but it is not normal. Morning marine-layer humidity settling on cold aluminum frames without thermal breaks causes condensation to bead and run, especially on east-facing windows in 94301. Over time this damages interior paint and can rot the sill. The fix is usually a frame with a proper thermal break or a glazing upgrade, and it can often be done without replacing the entire unit. Call (888) 635-0804 and we will inspect the frame before recommending a fix.
Yes, for homes built before 1978. Original single-pane wood sashes in Professorville and Midtown almost always have lead paint on or around them. Removal requires containment, HEPA filtration, and certified disposal, and skipping those steps is both a safety hazard and a legal liability. Our crews are trained on lead-safe work practices and build the containment time into every quote. Call (888) 635-0804 and ask us to check your paint date before the first window comes out.
