Lema Windows and Doors did a great job on our family home…read more They were very responsive. Leszek communicated everything about the project clearly, answered all of our questions with great detail, and provided the best advice. We originally contacted them about a patio slider and they provided the best quote, focusing on quality and what we wanted, and service. We asked them for additional help with another project that we were doing ourselves. They helped us resolve the issues we had with a different leaking window and door. They caught several problems with the advice and plans we'd been given, which saved us from long-term issues, so we ended up expanding the scope from just the patio to a door and window with them. We got the look we wanted, the safety we wanted, and it was all installed so quickly and professionally. The stucco work looks perfect and was also done very professionally. We will definitely use them for any future work on the house. Highly recommend.

Sal was able to help with good pricing to meet my budget needs. Gary then came next to do final measurements before ordering; this was pretty quick work and he was very thorough. Once the Windows were built and ready to be installed, the installation manager Lorna was very quick to schedule an installation date and accommodated my scheduling requests. On the installation day, Juanito and Mauricio arrived on time, worked very efficiently and professionally, and did exceptional installation work. I would highly recommend Cal Coast to anyone looking for new windows!

Their pricing was fair and transparent--no surprises, no upselling, just honest numbers that made sense. What really stood out was their timeline. They showed up when they said they would, stayed on schedule, and completed the project right on time. That alone is rare these days. The installers were top-notch--respectful, clean, and clearly took pride in their work. They treated our property like it was their own, which made the whole experience stress-free. If you're looking for a company that delivers on price, timing, and professionalism, this is it. Highly recommend!

Richard came out to provide a quote and explain the replacement process and which windows would be best. Tiffany helped me schedule and kept me in the loop on the project. She is fabulous! A few weeks later and Joey, Ken and their team efficiently removed our circa 1971 windows and installed the new ones. They were very considerate and cleaned up after themselves. I hardly knew they were there at the end of the day with the exception of my beautiful windows. No problem with inspection. Not only does my home look 100% better, but we are already noticing a difference in temperature, noise and light. I highly recommend Anlin Windows and the West Coast Windows and Doors team.

They responded quickly to my inquiry and every follow up email I sent. Brian went above and beyond to help me, and even shared my situation with Milgard. He was also very knowledgeable and recommended upgrading the screen door for the slider since the standard one can feel a bit cheap, and suggested upgrading the glass to help with temperature regulation. He also gave me a quote for the exact door I originally ordered from Home Depot, in case I didn't want to upgrade anything. I really appreciated the time he spent helping me, especially since it was just one slider door. Excellent customer service. They definitely have my business going forward. Highly recommend!

We visited Dolan's at both the Walnut Creek and Concord locations on two separate occasions while…read moreshopping for doors and windows. In both instances, there were multiple employees working at the front desk area on their computers. While they may have been busy, no one acknowledged or greeted us when we walked in. Even a simple "Hi, we'll be with you shortly" would have gone a long way. My wife spent about 10 minutes browsing the showroom during one visit and we still were not approached. We ultimately left both times without speaking to anyone. We understand that some showrooms operate by appointment, and if that is the standard protocol, that is perfectly fine. However, a quick greeting, asking whether we had an appointment, or offering to schedule one would have created a very different experience. We did not have this issue at Golden State Lumber or Ashby Lumber, where we were promptly acknowledged and assisted. Unfortunately, based on our experience, we will be moving forward elsewhere.
