Get matched with top window and door contractors in Diamond Bar, CA

"I've used Metropolitan before and will continue to use them for all of my door and window replacement projects! The entire team is knowledgeable, professional, and communicative. I chose Anlin windows and ProVia entry doors and I couldn't be happier with how great my home looks."

"Contacted me right away and gave estimate and after showing pics of the windows gave me an exact price a very fair price.. very friendly"

"Will was really professional and helpful would recommend & use the company again for any issue with my sliding door or issues with my closets sliding doors. Price for the work done is reasonable."

"Super happy with service from both Angi’s list and the handyman. He was professional, did a great job installing a dog door and was tidy cleaning up after. Recommend and will use again in the future"

"Gen mgr./sales Rep is the real deal; many yrs experience, very open & straight shooting, offered multiple vinyl dual pane gas filled options, & worked w/us to make the price 'work' per our budget for the brand & quality level we wanted. He/they made sure they quickly placed the Manufacturer order, while squeezing our installation in/end of Sept. before we left on a trip. Installation team was organized & didn't mind my occasionally checking the walls & windows as they progressed, though i did find more than one or two cuts/dents in the vinyl framework, which while being minor blemishes, should have been avoided (whether caused during transportation or during installation). They cleaned up near the windows well, though failed to vacuum their dirty paths from front door to the liv. rm & bdrm (though they did also vacuum up the carport moderately well). Finally, & its not a major biggie but, when they reinstalled the long living room vertical blinds system, they didn't leave it working as well as it was before they showed up. This 14 yr old blinds system wasn't problem free before they arrived so, i chose to let this more difficult to use system remain an ongoing issue/not originally caused by Brothers Home Improvement."

"Amazing! Felipe and his crew are so nice and so professional. They installed a double door where a window used to be and also upgraded two other doors. And installed a dog door. Everything just took a week!"

"Morgan called in advance of appointment to inform us that he was on his way. He removed the sliding glass door and screen and replaced, lubed and adjusted the door hardware for proper closure. Door work fantastic (like new) again. Great service for the cost and would highly recommend him for any door, window and doggy door installation or repair."

"Rigo ordered and just installed a sliding glass door in the back of our house. He did a great job! The door was a custom order and took four months to receive. Rigo kept us updated every step of the way regarding the status of delivery. Once we received the door, Rigo completed the installation exactly on schedule and did a very professional job. Not only did he do a great job on the installation, he also added and painted custom framing inside and outside that we requested. The craftsmanship was excellent. When Rigo was doing the installation, my wife notice a small tare in the screen from the manufacturer. Rigo removed the screen from the frame and replaced it with a new one during the same visit. Originally, we spoke to a number of contractors, including some from Lowes and Home Depot, but I am so glad we decided on Rigo. He did a fantastic job from beginning to end and was always very cheerful and pleasant, even when we made additional and unplanned requests. I would highly recommend Rigo to anyone who is looking for a good contractor to install doors or windows."

"Branden does a great meticulous job paying attention to detail. Branden takes his time but does it right. And he is very good with following-up if you want additional work done. Branden installed new screens for a couple of windows and also fixed a few other things that were broken."
