"Our story begins in 2013 when David Kain of Sunboss contracted to do a renovation of our property in Dana Point consisting of a two story exterior deck & patio adding 25% outdoor living space. This project was completed on time and at budget with excellent results. In 2024 we decided to add motorized screens to our downstairs patio as a recreation room. Although we had competing bids, Suboss was our first choice for this project due to their past performance and competitive pricing. It turned out even better than we anticipated. They have great people and attention to details. You will not find a more professional company to work with than Sunboss Rooms and Bath."

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"I hired a large company who hired ProServ as the contractor for the project. My contractor was incredible and efficient. Regretfully the company was not. Carlos, ProServ owner, made an incredibly awkward situation work out. I would give ProServ and especially Carlos rave reviews. The professionalism and honesty of the contractor and his crew is exemplary and quality of his work is exceptional."

FAQs for sunroom or patio enclosure building service projects in Ontario, CA

A sunroom is a fully enclosed space with walls of windows or glass. It allows you to enjoy the outdoors from the comfort of the indoors, protected from bugs and weather. It functions as an additional room in your home. A covered patio extends your home's roof over an outdoor area, providing shade and shelter while remaining open to the fresh air. It's a great way to enjoy outdoor living while being protected from sun and rain.

Adding screens to your porch is the most budget-friendly way to enclose it. Screening keeps out insects and debris while letting you enjoy the breeze and outdoor ambiance. It's less expensive than installing full walls or glass enclosures and doesn't usually require permits, making it an efficient way to upgrade your porch.

If you're transforming your porch into a fully enclosed living space like a sunroom, you'll likely need a sturdy foundation, such as a reinforced concrete slab, to support the structure. For a simple screened-in porch, you might be able to use the existing floor and support posts without additional foundation work. It's best to consult a professional to determine what's needed for your project.

An enclosed porch can be considered a living space if it's fully enclosed with solid walls and windows, has a proper roof, and includes heating and cooling systems. It should also have direct access from inside your home. When these criteria are met, the space becomes an extension of your home's livable area.
