Windows Installation in Concord

“We recently replaced all our windows and patio door, and Bestoff Windows did an excellent job. The entire project was completed in under two days, and everything—from the initial assessment to installation—was smooth and well organized.

Sergey, the owner, is great to work with—very straightforward, no sales pressure, and no upselling. His crew was professional, efficient, and paid attention to detail.

They came highly recommended by our neighbors, and they absolutely delivered. Highly recommend!“

“Darryll came and measured 4 of my 80+ year old windows. 4-6 weeks later I had replica windows in Douglas Fir and laminated glass. On my request, they were nice enough to drop them off for me to paint before install, because it would have been difficult to paint after install. Darryll and Edgar installed them. Darryll the owner is kind (though he might not immediately give that vibe), detail oriented, comes on time, measures accurately, and has a good rapport with his employee. Highly recommend.“

“Brian and his team delivered on their promise of high quality and attention to detail. We had a lot of windows, but the crew took their time during some of the hottest days this summer and did a thorough job. We would recommend Brian and Aames Windows & Doors to anyone looking for a high quality product and installation!“

“The BEST customer service I've seen. Kelly is the best. Great product, too!! Anlin are quality windows. I highly recommend West Coast Windows.“

“The service was gutter cleaning and leaf guard installation. When Jason stopped by, my gutters were literally growing weeds. The city tree on my property has caused high maintenance of the gutters. Decided to have leaf guards installed which will hopefully lessen the task of cleaning. All staff were very professional and personable. Communication was great. THANK YOU to Mark who showed me the Leaf Blaster guard which I think will work better than the easy lock screen that I initially selected. They were pricier but Quality First quickly processed a change order and installed my preferred guards at no additional cost. Thank you!“

“We bought a house in Vallejo and needed to replace the front door which was old and janky. I heard about Dolan's from a friend and so I filled out the form on their website and Travis contacted me a day later. He came out and assessed the job and guided us through the door selection process. The door we chose had to be ordered which took about 4 weeks and then we set up the install date. Tyler and José did a fantastic job and knocked it out in a day and a half. Don't hesitate to get your door from Dolans.“
