About California Sunrooms

California Sunrooms Co. has proudly served Contra Costa County and Alameda County for over 25 years. Our reputation as the number one east bay sun room East Bay dealer for custom sunrooms, patio rooms & enclosures comes from superior design, product quality, and hassle‑free construction. Our passion for quality sun room and enclosure installation and our attention to detail has earned us top recommendations by some of the finest architects and engineers throughout the bay area. Our large volume along with timely installations allow us to offer our clients the best value in patio room, sun room, patio enclosure, and patio construction in the East Bay. We also enjoy building the best room additions onto our customers’ homes. Nothing has inspired us more than hearing our clients tell us we’ve made their patio room and sunroom dreams a reality.

We Are a Certified Four Season Sunrooms Dealer

There are a variety of uses for a new sun room or patio room, and also a variety of sun room manufacturers to choose from. All sun room manufactures look similar in photos but function very differently; so the first question to ask is: Do you want your sunroom or patio room to be used all year or just two or three seasons a year?

Most East Bay home owners want a sunroom, patio room, or patio enclosure of the highest quality and they want to be able to enjoy that room addition year‑round. If you fall into this group, there is only one manufacturer that can fill your requests. In fact, the proof is in the name. “Four Seasons Sunrooms”. This is the only sunroom and patio enclosure manufacturer that can boast being America’s largest and best all year round sunroom, solarium, patio enclosure and conservatory manufacturer.
