Patio-to-sunroom conversion in Loma Linda CA - a room your slab can hold
If your patio sits empty most of the year, we'll enclose it into a real room, planned around your slab before anything gets built.
What does it take to turn my patio into a sunroom?
A patio-to-sunroom conversion in Loma Linda encloses the patio you already have as a one-story room attached to your house, so the space you've been looking at out the back door becomes a room you can use.
Most people who call us have a slab out back, often with a cover over it, and they want a room they'll actually sit in. The kind of room you pick moves the price most, since a three-season room costs less to build than one that's insulated, heated and cooled, and after that it's the size, whether the slab needs foundation work, and extras like plumbing. The schedule mostly turns on the city's plan check and inspections, and on what we find when I look at the slab. Once I've seen it, you get a written estimate with your own number.
How we handle a patio-to-sunroom conversion
Before anyone cuts into concrete, I find out what kind of slab you have, because that decides whether we can saw into it for footings and posts or need to plan around it. Then I look hard at where the slab meets the house, since a slab that runs out past the house wall leaves a ledge under a new wall, and if that joint isn't flashed with metal that sends water outward, rain works its way behind your siding. From there our crew frames the walls, sets the windows and roof, seals the room to the house and adds insulation if it's a four-season room. If your slab can't hold the room you want, I'll tell you on the first visit and we'll talk about what it would take, because fixing a foundation after the room is up costs you far more than doing it first.
Not every outdoor space starts as a slab. If yours is a raised wood deck, deck-to-sunroom conversion means checking the framing and footings underneath instead of the concrete. And if you want to use the room in July and January alike, look at our all season rooms, which are insulated, heated and cooled like the rest of the house.
Patio-to-sunroom conversion permits and inspections in Loma Linda
In Loma Linda, an enclosed patio is an addition to your house, and the city's Building and Safety Division issues building permits only after it plan-checks the project. Its inspectors then come out to check the work for structural, fire, health and safety requirements. Zoning and land-use questions go to the city's Planning Division, whose staff review residential projects and explain the development standards. Parts of the city are also mapped as Moderate, High or Very High fire hazard zones, and state law ties extra building standards and fire safety rules to those zones, so where your house sits can change how the room is built. We put together the plans and paperwork, file with the city's building office and meet the inspector at each inspection.
Most patios we see here are slabs poured years ago, some with an edge that runs well past the house wall, so we check both the slab and that edge before we draw anything. We find the same kind of backyard slabs on jobs in Redlands and Grand Terrace.
How a patio conversion works
Call or send the form
Call (909) 515-5048 or send the form and tell me a little about your patio. We set a time for me to come out myself.

We take care of the permit paperwork, and our crew builds in stages. Each stage is ready before the city's inspector comes out to look at it.
Walk the finished room together
When the room is done, I walk it with you. Look at the windows, the joint at the house and anything else you want to ask about.

Send the form and expect a reply within one business day. I'll set a time to come out, measure the patio and look at the slab, and the estimate is free, with no pressure and no obligation.
Questions before a patio-to-sunroom conversion
How much does it cost to turn a patio into a sunroom near Loma Linda?
In San Bernardino, adding a three-season room to an existing base usually costs about $95 to $140 per square foot, labor included. That figure leaves out insulation, extending heating or cooling, plumbing and permits, and larger rooms that need a foundation and have heating and air conditioning sit at the high end. Your written estimate shows which of those your room needs.
Should I build a three-season or a four-season room in Loma Linda?
If there's a good chance you'll want the room year-round, build it four-season now. A four-season room is fully enclosed, heated and cooled, with all-weather windows, while a three-season room usually has no heating or cooling and uses uninsulated windows or screens. Adding insulation later costs more than doing it up front, so I'd rather plan for it from the start.
How do I know if my patio slab is safe to cut for a sunroom?
Find out whether it's a post-tension slab, one with steel cables called tendons stretched tight inside the concrete, before anyone saws or breaks it. Another city's building guide warns that cutting a tendon can be very dangerous and expensive to repair. That's why we settle the slab type before any cutting starts.
How much can a contractor ask for up front on a sunroom in California?
California's contractors board caps the down payment on home improvement work at $1,000 or 10 percent of the contract price, whichever is less. After that, each payment has to be listed in the contract and match work done or materials delivered. If a bid asks for more up front, it's worth asking why.
How do I make sure a contractor is licensed for the foundation work on my sunroom?
Ask which license covers the structural part of the job, because under state contractor rules a residential remodeling contractor may not contract for structural changes to footings, foundations, load-bearing walls or roof structures. A patio room can touch several of those, depending on what the slab needs and how the roof ties into the house. Ask that of anyone you're considering, us included.
Do California energy rules apply when you enclose a patio?
They can, because California's Energy Code sets energy and water efficiency requirements for additions and alterations to existing homes, not just new ones. That's one more reason to settle the room type early, since a heated and cooled room is planned differently from one left open to the weather.
