1081 W 9th St, Upland“I am absolutely in love with our new windows and sliding door with a built in doggie door. They are beautiful-I actually dread covering them with window treatments because they look so good!
Now let’s talk about business. Everyone that we encountered in the preliminary stages (from quote with Jaime, visiting the showroom, and getting final measurement by Israel) were professional, friendly and explained everything really well. The installation crew was incredible. Talk about exceeding expectations-these guys were all about it. Shout out to Vincent, Leo, Nate, Joe, Frank, Israe, Enrique and Cristian. Thank you all for the outstanding work you did at our home. I appreciate your craftsmanship, keeping everything clean, patience with all of our pets, and your kindness. You really made this process go so smoothly with a touch of humor and kindness. Thank you all so much for!“

13238 White Fir Ct, Rancho Cucamonga“United Builders is great! My wife and I had initially hired a different (closer) company for one of three sliding doors we wanted installed and had a nightmare experience of months-long delays and general shadiness. Once the dust settled, we had our sliding door and a few more stress lines. So we sought out United Builders for the remaining two doors. Their whole process was easy, direct and high-quality. They came to our house and even inspected the other guys' work to A) make sure it'd been installed correctly and B) make sure the two new doors matched the aesthetic of the first one. The whole process was fast, honest and transparent. And everyone we interacted with erred on the side of over-communicating, not under-communicating, which was a nice reassurance. Strong recommend!“

615 N Benson Ave Unit I, Upland“I cant begin to explain what an amazing experience we had with this company. Our first encounter was with Steve and he was amazing, paid attention to detail, and was not out to price gouge us, which we so appreciated. The workers that arrived were so nice and I trusted them all. The work they did on our house was not an easy job to say the least. The prior owners of our home had installed defected windows that didn't fit. Our new windows fit and are just beautiful. I can't say enough about this company I would HIGHLY recommend !!!!!!!!!“

1072 W 9th St unit c, Upland“Mark and Nick have taken care of a half a dozen projects for me over the years. Always with great results. As a Realtor I rely upon my contractor to take care of my clients homes. Custom Construction is always done that quickly and efficiently. Good craftmanship. Fair prices.“

9239 Archibald Ave, Rancho Cucamonga“What we were looking for in contractors was integrity, reliability, and clear communication — and Jon and Ian checked every box.
They recently helped us renovate our master bathroom and kids’ bathroom, and we truly can’t express how much we appreciate their exceptional workmanship.
Everything others have said about them is absolutely true. They showed up on time every day as promised, cleaned up thoroughly at the end of each day, and followed through on every commitment they made.
What impressed us most was that they take real pride in their work, yet they remain humble and open to feedback. Anytime we brought up a concern, they addressed it immediately and professionally. They amazed us every single day with their skill, work ethic, and attention to detail.
We can’t wait to have them back for more projects in our home. Thank you, Jon and Ian — you are exactly what every homeowner hopes to find in a contractor.“

243 E Holt Ave, Pomona“We needed a new glass door at our office building. Some useless, lazy thugs broke in to our tenant's business, and we had the door boarded up. Nagco Glass did a great job, very professional, decent pricing, and accommodated us very quickly! We will definitely use them again.“
