    Why We Started Diamond Builders

    Professional diamond cutters are known for their attention-to-detail, precision, and laser-like focus.  When it comes to residential and commercial window and door installations, those same features are important when it comes to choosing the right installer for your valuable home or business.  You want the job done right the first time while having the peace-of-mind that your windows are going to hold up year around against the heat, cold, rain, smog, salt water and other elements that we all experience around Los Angeles and Ventura County.

    At Diamond Builders, when we started our company in 2005 it was built upon those same principles used by experienced diamond cutters, as we wanted to be a cut above other installation businesses in this area.  For example, when we work with home or business owners, we start by carefully listening to what their personal objectives are.  All our installers are highly-trained, experienced and specialize in all types of window and door materials, including aluminum, fiberglass, vinyl and wood.  To get some exciting ideas for your home or business, check out some of our transformative window and door results on our Gallery page now!

    We knew that it was important for Diamond Builders to be licensed, bonded and insured to protect our clients, and to communicate openly and honestly at all times.  In-order-to provide the highest level of client satisfaction, we also started offering an ironclad, one-year warranty to back all our installations, and to ensure the peace-of-mind of those we serve.  It also didn’t make sense to charge people for estimates, so we offer free price quotes and measurements for all our commercial and residential projects, big or small.

    Our overall objective at Diamond Builders is delivering the highest quality, beautiful window and door installation results in the Los Angeles area using a customer service approach that’s honest, reliable and friendly- all within a seamless process that fits within any budget.  Ask any of the 100s of satisfied home and business customers that we’ve proudly installed windows and doors for during the past 13+ years, and they’ll no doubt relate that we stand behind our work.  When you need a high-quality professional window or door installation, call the experts at Diamond Builders in Agoura Hills and we’ll promptly get it done right the first time!
