Window Company in San Jacinto, CA
We’re Westlight Windows & Doors, and we replace and install windows and doors across San Jacinto. If your home still has its original single-pane aluminum windows from the 1970s or 1980s, you already know the problem: the frames get hot enough to burn your hand by mid-afternoon, and the Santa Ana winds find every gap. Most San Jacinto jobs we take on involve swapping those frames for double-pane vinyl or impact-rated glass that actually seals. Call us at (760) 624-3669 for a written price before any work begins.
Why San Jacinto Homes Are Different
San Jacinto sits in the San Jacinto Valley, where summer temperatures routinely top 100°F and the fall brings Santa Ana wind events that push hard against every window and door in the house. Older ranch homes built in the 1960s through the 1980s, especially east of State Street, still carry original aluminum-frame sliding windows with no thermal break. That means the metal frame itself conducts heat straight into the room. By July, those frames are too hot to touch, and the glass seal has usually failed anyway, leaving a permanent haze between the panes.
Newer stucco tract homes from the 1990s and 2000s have a different issue. The vinyl windows they came with are fine in principle, but many were installed quickly and poorly. We see gaps around the rough opening, uneven shimming, and weatherstripping that pulled away within a few years. San Jacinto’s dry heat and wind cycles expose both problems faster than milder climates would. Any replacement or installation here has to account for thermal expansion, wind-driven dust, and a summer sun that can warp a cheap frame in a single season.
Some neighborhoods also sit close to the foothills, where drainage and afternoon heat patterns change a few degrees compared to the valley floor. It changes how we seal and flash, and it’s why we quote San Jacinto jobs after looking at the house itself, not from a generic spec sheet.
Our Main San Jacinto Services
Three services make up most of the San Jacinto work we do. Each has its own page with the full pricing breakdown and the details of what the job involves here.
Window Replacement in San Jacinto
Replacing old aluminum frames in San Jacinto means more than swapping glass. We remove the entire unit down to the rough opening, inspect for rot or water damage around the frame, and install a properly flashed replacement that can handle the valley heat. Single-pane aluminum windows east of State Street are the most common call we get. Read the full breakdown on our Window Replacement in San Jacinto page.
Window Installation in San Jacinto
New construction and addition work in San Jacinto’s newer tract areas often needs windows installed from scratch, which is a different job than replacement. The opening is raw, the flashing has to be done right before stucco or siding goes on, and the window has to be set perfectly square so the panels seat and seal. Details are on the Window Installation in San Jacinto page.
Door Installation in San Jacinto
Hollow-core interior doors and builder-grade exterior doors are common in San Jacinto homes from the 1980s and 1990s. Exterior doors take a beating in this climate: afternoon sun on a west-facing entry, wind-blown dust against the weatherstripping, and heat that warps a thin slab. We replace and install entry doors, patio doors, and interior doors with proper shimming and sealing. See Door Installation in San Jacinto for the full scope and pricing.

Brands We Service in San Jacinto
We install products from eight manufacturer lines, including PGT, CGI, CWS, and ES Windows. That matters in San Jacinto because the right glass for a west-facing window in July is not the same as the right glass for a shaded north wall. Learn more on our brands page.

You get the written price before the work starts, and it does not change at the door. That is the Kingswell Guarantee, and it applies to every job we take in San Jacinto.

FAQs About Window Company in San Jacinto
Most San Jacinto quote requests get a response within one business day, and we schedule the visit during a specific arrival window, not a four-hour shrug. Call (760) 624-3669 and a live person answers, 24 hours a day. You will have a written price before any work starts.
Most replacement window and door jobs in San Jacinto do not require a permit when the opening size is unchanged, but any structural or new-opening work does. We handle the permit paperwork and pull what is required. Call (760) 624-3669 to confirm what applies to your project.
No. The price we write down before the job begins is the price you pay, period. If we find hidden damage behind an old frame, we stop and show you what we found and price the change separately in writing before touching it. That is the Kingswell Way: say the price before the work, put it in writing, and stand behind the result. Call (760) 624-3669 for a free estimate.
