We recently had eight windows and a sliding door installed by Cal Coast Window and Door, and the…read moreentire experience was outstanding from start to finish. Chris did an excellent job guiding the project and making sure everything went smoothly throughout the process. The installation crew (Manny and Omar) were absolutely amazing, professional, efficient, detail-oriented, and incredibly clean. They worked hard, respected our home, and left everything spotless when the job was complete. If you're looking for a company that provides great communication, quality workmanship, and exceptional customer service, I highly recommend Cal Coast Window and Door.

We wanted to replace all our original 1960s-era single-pane windows with double-pane windows. We…read morealso wanted a storm door for our front door. We got an estimate from Andersen (less the storm door). Their products and installation method were top-notch, but so was their estimated price! So we wanted something more economical. After some research we heard Milgard windows using an "retrofit" installation would be more in our price range. We also wanted a window/door-installation company that gave us a good price estimate (1/3 the cost of Andersen), was in our locale (Tri-Valley) , and had 5-star rating already. So we were happy to find Cal Coast that met those criteria. The initial estimate process was straightforward. Our estimator was friendly and efficient. The format of the estimate came in digital PDF format. It was easy to print, and the details and layout were very helpful with diagrams of what the windows and door would look like with dimensions. One measurement for one window was slightly off. I mentioned that to my estimator. He assured me that was not a problem because if I accepted their estimate, then the next step was for another technician would come out to the house to re-measure the windows more accurately and in more detail. We did accept the estimate, and indeed another technician came out to do detailed measurements. Then we received a revised and more detailed contract in that same great layout! The estimator kindly set our expectations that our windows and door were going to take 5-6 weeks to custom manufacture and about 1 to 2 days to install. Those timings were right on target, which helped us in planning other events in our life. Installation only took 1 day! The crew was great - courteous, hard working, and efficient. They put foam insulation in the space between our window frames and the new windows. The caulking work was professional. I was pleased. And the crew cleaned up after themselves perfectly. Another thing I was pleased with was Cal Coast's production manager helped me apply and get my city building permit for the new windows. The day of installation, the foreman handed me a nice folder with the printed permit with other instructions. I really appreciated that. Also after installation she worked with my city building department to schedule a final inspection by a city inspector. When the inspector came out, because the product and installation were superb, it passed with no problem. Of course, I paid a little more to have this permit processing service, but it was well worth it. Finally, as you can tell from this rather long review, I'm very pleased with our experience with Cal Coast and the Milgard products. I add my 5-star review to others that have gone before me for Cal Coast!

Never knew about life time warranty until last month, one of the window cracked. We didn't have any receipt or anything, just an email we did 14 years ago. We just contacted the company on their website and amazingly, they have the record by the address. The service department was so helpful, they contacted us and contacted the manufacturer to set up appointment with the case number to get it replaced. The windows were replaced 14 years ago in one day and we had many custom sized windows. The amazing thing is they know exactly which window that cracked by us describing the location of the window. Anlin Delmar (Milgard) called us and setup the appointment. They came and replaced the windows in a few hours. It was amazing and we're extremely happy. Now we know, go with the best and reputable company like Custom Exteriors and a good manufacturer like Anlin Delmar to have after service years after the work is done. Would we recommend Custom Exteriors and Anlin Delmar? The answer is obvious, YES.

They were noticeably more affordable than the other bids we got and there were no surprise charges along the way, which seems rare with home improvement projects. Everything was transparent and laid out up front. They showed up exactly when they said they would, and communication was excellent the entire time. Every question we had got a quick, clear answer, and we always knew what to expect next. Didn't have to call multiple times or send a bunch of emails. The new windows look fantastic the crew cleaned everything up after the install. No dust in the house or materials in the yard. We have recommended Bestoff to a few friends already. If you're looking for a window installer who's fairly priced, dependable, and respectful of your home, we'd recommend them without hesitation.

From the very first conversation, it was clear I was speaking with a true professional. Triangle Construction (Daniel Curtis) was incredibly responsive, transparent, and thorough, all qualities that are surprisingly rare in this industry. He took the time to walk me through the process, answered all my (many!) questions with patience and clarity, and provided insights that made it clear he has deep expertise and a passion for doing things the right way. His professionalism, integrity, and clear communication gave me so much confidence. If you're lucky enough to work with him, you're in excellent hands. I wouldn't hesitate to recommend him to anyone looking for high-quality work and a contractor who genuinely cares. If my timeline had been more flexible, I would have hired him in a heartbeat. Highly recommend!
