I had been shopping for my backsplash and countertops and found this place on Google. I was looking for something unique and special and not the same run of the mill designs. When Sabo took me into his warehouse I was amazed with the selection he had. I immediately was gravitated to this gorgeous porcelain slab for my backsplash and a coordinating quartz for my countertops. Thank you Sabo for your patience and expertise. I would highly recommend your business. I’m extremely happy with my kitchen.
Ok where do I start these guys rocked the house literally. Check out the porcelain work they did on the fireplace, and Quartz countertop slabs it was a whole Kitchen and the bathroom vanities. The value of their work shows and it really enhanced this old out of style home into a modernized dream getaway.If you are hesitant to hire them don’t because i am a testimony for their work as you can see in the photos posted. They were fun to work with and made the transition smooth.

I recently had the pleasure of working with Extended Development to install countertops in my dental office. I must say, their quality and craftsmanship were outstanding. The attention to detail in Extended Development's work was evident from the moment the countertops were installed. The quartz material they used was top-notch, providing a beautiful and durable surface that is perfect for a dental environment. The seams were practically seamless, creating a smooth and elegant finish. I highly recommend Extended Development for anyone in need of high-quality countertops. Their work truly exceeded my expectations.

We visited over 15-20 different granite slabs and tile stores in Ventura County and Hollywood. Until we stopped at Extended Development and met Sebo he was very helpful and very knowledgeable he took the time to explain and show us different slabs. We will tell our friends and relative about this place they are great.

Great experience! Process was fast, without any glitches or multiple sales people to deal with. Purchased the stone and fabrication from one entity who delivered exactly as stated, unlike the hurdles at big box or membership stores. I would strongly recommend them to family, friends or neighbors. We chose the quartz pattern we liked and had the kitchen measured within the next two days. Three days later the counter tops were fabricated and installed. Installers were very professional and made sure to clean before leaving. Price for the quartz slabs, fabrication and installation was worth it. Best experience of this type ever. Will go back to them for other stone related services for sure.
