  Rick and United Builders did a fantastic job for us. We really appreciate Rick’s honest approach and the integrity he brought to the project. We had them update our windows and sliding doors, and we’re thrilled with the Anlin products – they’re really easy to use and the soundproofing is a huge improvement. We’d absolutely recommend them! report abuse

  “We were absolutely thrilled with the service we received! They assessed our doors and, incredibly, were able to repair them at a much lower cost than a full replacement. If you’re looking for door repairs, I wholeheartedly recommend this company – they’re fantastic!” report abuse

  “We recently had United Builders replace all the windows in our house, and we couldn’t be happier with the experience. From the start, they were incredibly professional and straightforward – they gave us a competitive quote that was lower than other bids we’d received. They clearly explained the process, including the delivery timeline and how the installation would proceed, and they kept us informed every step of the way. Everything went exactly as planned, the windows arrived on time, and there were no unexpected charges. The installation crew was fantastic – punctual, efficient, and really took pride in their work. They completed the job in two days, just as they’d estimated. We’re so pleased with both the quality of the windows and the service we received, and we wholeheartedly recommend United Builders.” report abuse

  Overall, I was really pleased with the experience. They responded quickly with the quote and got the job started promptly – replacing my windows with the sound package and installing a new door. The new windows and door are fantastic; I can barely hear the weather, and there’s no more draft. They open and close easily too. Just a small note – I had to remove and reinstall my blinds and curtains, so it’s worth checking if that’s something they can include in the price or if I’ll need to handle that myself. report abuse

  Rick and United Builders did a fantastic job installing all 19 of our windows and the slider. We really appreciated that they didn’t pressure us to do the whole job at once – splitting it into two parts worked out perfectly. The windows themselves are top-notch – dual pane and exactly what you pay for. I’d definitely recommend them, especially considering how hot it’s been in Southern California lately! report abuse

  “I couldn’t be happier with the whole experience! I got several quotes, and thankfully, my Terminex representative steered me towards United Builders – he said they offered the best price and don’t spend money on advertising like some other window companies. The installation team was fantastic too! They arrived on time, a crew of six, and completed the job in just four hours. Everyone was so polite, professional, and really took care of everything. The windows themselves are fantastic – I haven’t heard my heater running at all, which is amazing since it used to cycle on and off constantly. Plus, with the street noise, the windows have made a huge difference. I’m absolutely thrilled with United Builders!” report abuse

  “We were really pleased with Rick and United Builders. He gave us a fair quote with no hidden fees, and we’ve used them before when we bought our last house – they did a fantastic job installing the windows then. The installers were incredibly professional and took the time to clean up thoroughly after themselves. We’d definitely recommend them!” report abuse

  I couldn’t be happier with United Builders! I started my window replacement project back in late 2014, and I’ve been consistently impressed with their professionalism, the fantastic quality of the materials, and their incredibly responsive customer service. Rick was a pleasure to work with – truly reliable and someone you can count on. I really wish they could have done the whole job at once, but I’m very pleased with the work completed so far and definitely plan to use them again to finish up the remaining windows. I wholeheartedly recommend them and would absolutely give them five stars! report abuse

  “We couldn’t be happier with United Builders! From start to finish, they were incredibly professional and genuinely helpful. They really took the time to understand our needs, especially given the size of the project – over 40 windows – and worked with us to phase the installation to fit our budget. Most importantly, we felt we could trust them completely, which is absolutely essential when hiring a contractor. The windows and sliding glass doors themselves are fantastic; we've already seen a huge difference in our energy bills during the summer, and the rooms that used to get unbearably hot are now so much more comfortable.” report abuse
