AfterWindow Company in Lafayette, CA
Window and door work in Lafayette runs on two things: hillside sun exposure and homes that were built to a different energy standard than what makes sense today. Juniper Windows & Doors handles replacement and new installation across Lafayette with written pricing before any work starts, plus a 365-day parts-and-labor guarantee on every completed job. If you’re pricing out a project, call (682) 281-2168 and you’ll get a real person and a real number range, not a callback queue.
Why Lafayette Homes Are Different
Lafayette sits in a set of rolling valleys where afternoon heat lands hard on west-facing glass, while mornings on the east side of the hills stay cool longer. That swing means U-factor matters more here than in flatter parts of Contra Costa County: a window that performs fine in Oakland can feel like a heat lamp by 4 p.m. on a Lafayette ridge. Homes in neighborhoods like Burton Valley and the streets off Moraga Road skew toward 1960s and 1970s ranch construction, which often means aluminum frames, single-pane glass, and rough openings that have shifted over decades. Relator Road and the hills above downtown see more custom builds where sightlines and finish work get scrutinized. We also work around Lafayette’s hillside setback rules and the city’s design review process for visible exterior changes, which can add a week or two to a permit timeline depending on the scope. None of that is a problem if it’s priced and scheduled honestly from the start.
Our Main Lafayette Services
Most Lafayette homeowners reach out for one of two reasons: existing windows and doors have hit the end of their service life, or a remodel or addition calls for new units. Each service has its own Lafayette page with full pricing and detail.
Window Replacement in Lafayette
Replacement in Lafayette usually means pulling aluminum or tired wood frames out of stucco and siding openings, correcting any rot or sag at the sill, and setting a new unit that actually seals. Hillside homes off St. Marys Road and Upper Happy Valley Road tend to have more west-facing glass, so impact-rated or low-E options come up often. We walk the house, measure every opening, and write the price down before anything gets ordered. Full details on Window Replacement in Lafayette.
Window Installation in Lafayette
New installation, not replacement, comes up on Lafayette additions, detached ADUs, and full tear-outs where the rough opening is being rebuilt anyway. That changes flashing, waterproofing, and order timing. On new construction we coordinate with the GC or handle the full opening ourselves. You get the same written price and photo documentation as a simple swap. See Window Installation in Lafayette for scoping and costs.
Door Replacement in Lafayette
Lafayette entry doors take real sun on the south and west sides, so warping and finish wear show up faster than homeowners expect. We replace front entries, patio sliders, and French doors with units rated for the exposure, and we handle the threshold and jamb work older Lafayette homes usually need. Every door job gets a locked written quote before we order anything. Details on Door Replacement in Lafayette.

FAQs About Window Company in Lafayette
Most Lafayette quote visits are scheduled within two business days. You’ll get a written price before the visit ends, and if you book, a live arrival time on installation day. Call (682) 281-2168 to lock in a visit.
Straight swaps with no change to the opening size typically don’t trigger a full permit cycle, but visible exterior changes on hillside lots can fall under Lafayette’s design review. We flag that at the quote stage and handle the paperwork if it applies.
No. The price we write down before ordering is the price on your final invoice. The only change would come from something we can’t see until we open the wall, and that gets quoted and approved separately before any added work happens. Call (682) 281-2168 for a free estimate on your project.
