I called United Windows for warranty work on our patio slider screen doors. The wheels were bad and…read morethey were discontinued. Jonathan the manager replaced both of our screens with new track under warranty. Their level of service was 2nd to none. We will continue to do business with this company because they are one of few who stand behind their product. Their windows are good quality and they are backed up with an excellent warranty!

Very satisfied with the work this company did for us! They performed a tune up on our front door…read moreand 10 casement windows. The front door had gaps with air leaks and our smart lock couldn't properly lock due to the latch not catching the door when closed. They fixed it perfectly! We thought the windows were original due to the building construction being from the 1930s but it appears the previous owner (a subpar flipper) custom-made these windows to match the style of the building and did an absolutely terrible job. The construction of them is low quality and they did nothing to prevent water intrusion or air leaks. We had water coming through with the winter rains and heat during hot days. It was very easy to receive a quote from Nick with transparent pricing and he offered to come perform the repairs when he had a free day in his schedule. He followed through with that offer, and because we were flexible, we had the windows tuned up within two weeks of my first request and the job took one day. His crew was extremely professional, knowledgeable, and clean during their visit. Opening and closing the windows is completely different than before. They are snug when closed and the waterproofing is consistent with the standard for these style of windows. I immediately could tell the difference when the AC was in use later that day. Usually, there is a temperature difference between our bedroom, living room, and kitchen and we have sensors in each room. Now, they are all reading the same temperature and you can feel it in the air. That type of comfort is well worth the small investment if you are someone who is temperature sensitive. I have no doubt the rain won't come in the next time it covers LA! Preserve your architecture and hire a company like this to help extend their lifespan or create custom ones that will last even longer.

They were highly thorough and made sure to do a quality job. Windows look really nice. Note they're of course a window contractor so they hire an installer - in my case it was from a small window company in the OC. They called me after the install to ask about how everything was and after I said things were great they requested a review which is absolutely fine. I also get the idea that they take accountability for any issues and work to resolve them. That's the benefit of going through a contractor that's licensed bonded and insured and takes accountability. I'd hope any contractor was like this - this seems like the standard for any competent contractor but unfortunately there are tons of flaky people and companies out there.

They also had pretty great pricing and I am so grateful to have found them!
