Glass Repair & Installation in Montclair

American Glass Experts serves Montclair as part of our Southern California coverage area, operating out of our Reseda base about 55–65 min away. We're a licensed C-17 glazing contractor (CSLB #1125850) handling residential and commercial glass work throughout the city.

Montclair is a small inland city at the LA/San Bernardino county line. In terms of glass work, Montclair's homes are primarily from the 1960s through 1980s — the era that produced the most widespread dual-pane seal failures we see today.

We handle all of these under the same C-17 license — residential and commercial on the same ticket.

For Montclair jobs, we provide a free on-site estimate with a firm price before any work begins. Most standard residential glass projects are scheduled within 1–2 weeks. Emergency calls are handled on a priority basis — call (805) 750-6471 directly for the fastest response.

Needed a broken window replaced and American Glass Experts exceeded all expectations. Exceptional attention to detail — installed seamlessly and fast. The team made sure everything was clean and tidy after the job. Would definitely hire them again.

Frank came out to measure for glass partitions in our office and recommended 1/2-inch glass for the space. The crew completed the installation cleanly and professionally. Solid commercial work — would use them again without hesitation.

Bryant and Franklin did an amazing job on our shower glass. Installation was done within five days and the overall price was great. The whole process was smooth from measuring to finishing touches — couldn't be happier.

Responded quickly, arrived within days to measure, and finished ahead of schedule. The insulated tempered glass panel was installed with real precision and the moulding was reattached so cleanly that no repainting was needed. Thorough cleanup after — couldn't tell anyone had been there.

Reached out for a shower enclosure estimate and Frank responded the same day. He walked me through hardware options, explained the warranty coverage, and made sure everything stayed within budget. Really appreciated how knowledgeable and clear they were from the very first call.

Frank and his team came out to measure both bathrooms for frameless glass doors and panels. Everything turned out beautifully and pricing was great compared to other quotes. The process was quick and smooth and the team was professional throughout. Would definitely use them again.
