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.

Friendly and the finished product is good. They are fairly quick and have a good stucco patch guy…read more Would work with Lema again.

We hired Sergey and Bestoff Windows to replace every single window in our home and couldn't be…read morehappier with how it went. 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.

I highly recommend Bestoff Windows! From my very first consultation with Sergey, the owner, I felt…read morecompletely at ease. I had already met with quite a few window companies, and what stood out about Sergey was that he never gave me a sales pitch. He was knowledgeable, honest, and focused on providing useful information so I could make the right decision for my home. We even walked around my complex together to look at other windows, which I really appreciated. On installation day, the team was professional, courteous, and did a great job. I am very happy with my new windows and the finished result. What has impressed me most is the customer service and follow-through. When I recently noticed a minor issue with the caulking on one of the windows, I texted Sergey and he came by right away to take care of it. That kind of responsiveness is so appreciated and really speaks to how much he stands behind his work. The entire experience has been easy and stress-free, from consultation through installation and follow-up. I would absolutely recommend Bestoff Windows to anyone looking for quality windows and a contractor they can trust!

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 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.

Richard came by to give us an estimate and he was very thorough, explained all the options, helped me make decisions, and was patient enough to walk and talk as I chased my toddler around. The customer portal was easy to navigate and move the process forward. We were desperate for the new windows and asked if our install date could be moved up, and Tiffany was so amazing, worked her magic, and got us our windows before the hottest months of summer. We are so grateful. The install team was excellent! From start to finish they were so hardworking, professional, kind, and clean. They were so conscientious to not leave any mess behind and I swear my house was cleaner after they left! Joey was so helpful and when I asked if they could complete my daughter's room first they made it happen so that she could go back to playing in her room asap! He and his team went above and beyond to make sure everything was ready for us and even did a mock-up on some trim I was unsure about so that I could feel good about my decision (it looks amazing!). They were so fast and efficient and replaced all 12 windows in our home in just 2 days! The house is staying cooler, we can get fresh air now, the view out the windows is so clear, and our electricity bill has already gone down.
