Window Company in La Puente, CA
Juniper Windows & Doors is the window company La Puente homeowners call when they want a written price before work begins and a 365-day guarantee after it’s done. La Puente homes run the gamut from 1950s ranch houses with original single-pane windows to newer stucco builds that need impact-rated glass to handle the valley heat and Santa Ana wind gusts. Whether it’s a sagging front door on a Hacienda Boulevard property or a full window replacement in the hills above Valley Boulevard, every job gets a live arrival time, photo updates, and a digital invoice. Call (682) 281-2168 for your free estimate.
Why La Puente Homes Are Different
La Puente sits in the San Gabriel Valley, where summer temperatures regularly push past 95 degrees and the afternoon sun beats directly on west-facing windows along Amar Road and Glendora Avenue. That heat exposure is brutal on window frames. We routinely see wood frames that have dried and cracked around the edges, letting conditioned air leak out and pushing cooling costs up. Vinyl and aluminum frames hold up better here, but the seals still break down faster than they do in coastal climates. When we replace a window in La Puente, we’re almost always addressing heat damage, warping, or a failed seal that makes the glass fog up between the panes.
The housing stock matters too. A large share of La Puente homes were built between 1950 and 1980, which means standard-sized windows that are now below code for egress in bedrooms and for insulation. Many of these homes have aluminum sliders from the original build. The U-factor on old aluminum is poor, around 0.98 or worse. A modern low-E window gets that number down into the 0.25 to 0.30 range, which is a huge difference in a climate that gets triple-digit heat. Doors have their own issues: South-facing entries take direct sun most of the year, so we see warped frames and faded door slabs more often here than anywhere else in the area. Permits are handled through the City of La Puente, and we pull them when required so your inspection passes the first time.
Our Main La Puente Services
Most La Puente homeowners reach out to us for one of three projects: replacing worn-out windows, installing new windows in an addition or remodel, or swapping a tired entry door for something that seals tightly and looks right. Each service has its own La Puente page with full pricing and details.
Window Replacement in La Puente
Window replacement in La Puente usually means pulling old aluminum sliders or dried-out wood frames and putting in new energy-efficient units that can handle San Gabriel Valley heat. We measure every opening, check for water damage around the rough opening, and install new flashing before the window goes in. Most projects take one to two days once the windows arrive. See the full breakdown and local pricing on our Window Replacement in La Puente page.

Window Installation in La Puente
When you’re adding a new window to a La Puente home, whether it’s for an ADU, a room addition, or turning a dark corner into a bright reading nook, the work starts with framing and waterproofing done right. We coordinate with your contractor or handle the full scope ourselves, depending on the project. La Puente’s stucco exteriors mean careful cutting and sealing around the new rough opening. Every new window gets a written price before cutting starts. Get the details on our Window Installation in La Puente page.

Door Replacement in La Puente
A new front door in La Puente has to do three jobs at once: hold up to direct afternoon sun, seal tightly enough to keep cooling costs down, and look good from the street. We replace entry doors, patio sliders, and French doors with units that fit the existing rough opening or a new one, depending on what the home needs. Pre-hung doors go in on most La Puente jobs. See pricing and what to expect on our Door Replacement in La Puente page.
