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.

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.

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!

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 cleaned up everything so well it was hard to tell they were ever here.
