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!

They installed 3 new windows and a set of patio doors for my house. They were super responsive in every stage of the process. Emails were usually returned within an hour and always within the day. Their lead time estimate in getting the windows made was spot on. The quality of the windows feels good so far. I have a 100+ year old house with big old solid wood windows and I'll admit the new vinyl ones don't have the charm or look/feel of original wooden ones. But Windows4U also convinced me that replicating this old look would cost 4x as much. And its not their fault I chose the vinyl ones. They installed all the windows and door in one day and the team that was onsite worked HARD. Shout out to Mikhail and Vladimir who did a great job.

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.

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.

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.

Well my 95 pound German shepherd crashed through one screen once but that is not Phantom Screen's fault. So today I added 2 more.

It is a pretty effective bad guy deterrent at the door to my garage along with another big German Shepherd sleeping at the inside enjoying the breeze! But the new doors' release is welcome at the new locations. And the installer threw in a can of silicone spray. I'd say the only drawback is the screen door seems to be a magnet for dog hair. JK.
