Four season sunrooms in East Hemet CA - a room you can use in July and January
Your patio sits empty most months, too hot or too cold. We build a sealed, insulated room you can use every month.

What is a four season sunroom, and does your house need one?
A four season sunroom is a fully enclosed room with all weather windows and its own heating and cooling, so homeowners in East Hemet can use it on a hot July afternoon or a cold January night instead of only in mild weather.
Most people who call us have a patio, a deck or a quiet back wall they'd like to get more use out of, and the first thing we settle together is whether the room needs heating and cooling, because that's what makes it a four season room. The price moves mostly with the size of the room, whether it needs a new foundation or can tie into the one you have, and the glass, insulation and heating and air you choose. The schedule usually turns on the permit review and on ordering the glass once the design is set, and the written estimate after my visit puts the figure for your own room on paper.

Four season sunrooms, inside and out
How we build a four season sunroom
A four season room is only as comfortable as its insulation, and that's far easier to put in during the build than afterward, so before anything is ordered we decide with you on the glass and on how the walls, roof and floor will be insulated. Then we prepare the base or tie into the one you have, frame the walls and roof, and set the glass, sealing each joint with care because the corners and the line where the room meets your house are where water and heat find their way in. Licensed trades run the electrical and the heating and cooling, and our crew finishes the inside, cleans up and leaves the room ready to furnish.
Not every room needs heat and air. A three season sunroom usually has no heating or cooling and uses uninsulated windows or screens, so it's a lighter build that suits spring and fall more than August, and if you mainly want a covered patio closed in against wind and dust, our patio enclosures do that job. When you're unsure which way to go, I'm glad to walk you through both.
Why East Hemet homeowners call us for four season sunrooms
The estimate comes from me
I come out for every estimate myself, and I'm on site with our crew while the room goes up. The person who measured your house is the one checking the seals, so nothing gets lost between the visit and the build.
Years of window and door work
I spent many years installing windows and doors for other companies before I started building sunrooms here in East Hemet in 2023. That work taught me how water and heat slip through the smallest gap, which is why careful glass work and tight seals are what we're known for.
Permits handled with the county
East Hemet is one of the unincorporated communities Riverside County serves, so your permit goes through the county rather than a city office. We check with the county what your room needs, and when a permit is required we prepare the application and plans and meet the inspector on site.
Licensed and fully insured, trades included
We're licensed and fully insured, and we bring in licensed trades for the electrical and the heating and cooling a four season room calls for. That keeps each part of the job in the hands of someone licensed to do it.
A four season room has to stay dry and comfortable on the hottest afternoon, so call (951) 484-2079 or ask for your estimate and tell us how you'd like to use the space.

What happens after you call about a four season room
Call or send the form
You call (951) 484-2079 or write to us through the form, and we set a time for me to come out. Mention the patio, deck or wall you have in mind so I know what to look at first.
I visit and measure
I look at the base, the wall the room will join and how the sun falls on it, and we talk through how you'd like to use the space. You get a written estimate for the room we discussed, so you can see what the price covers before you decide anything.
Permit, build and walk-through
Once you decide to go ahead, we look after the permit side and build the room, with licensed trades handling the electrical and the heating and cooling. When it's finished, we walk through it with you and check the windows, doors and the corners where it meets the house.
Four season sunroom questions
What does a four season sunroom cost near East Hemet?
A four season sunroom of about 200 square feet in Riverside County usually costs about $30,000 to $60,000. Larger rooms that need a foundation and have heating and air conditioning land toward the high end of local prices. Your free written estimate gives the figure for your room.
Can a sunroom go on my existing patio slab or deck?
Often it can, as long as what's underneath is sound. Every sunroom, including one on an existing concrete slab or wood deck, needs a continuous path that carries its weight and forces down to a sound foundation. I check the slab or deck at the estimate before we plan on reusing it.
Who handles building permits for a sunroom in East Hemet?
The Riverside County Building & Safety Department handles permits for East Hemet. Its permit list names enclosed patios, patio covers and additions, not four season sunrooms by name, so your room's needs should be confirmed with the department before anything is built, which we do as part of the job. The county asks that applications go in online at rivcoplus.org and that questions and status checks go to landuseinfo@rivco.org.
Should my sunroom open into the house or be closed off?
Open it to the house if you want the room to work as part of your living space, and close it off with a door if you'd rather have a separate room with its own heating and cooling. The national sunroom specification treats a heated or cooled room open to the house as habitable, and a closed-off room with its own system as non-habitable, so the choice shapes how the room is designed. I usually ask how your family will use it before I offer an opinion.
How do I check that a contractor can legally build a sunroom in California?
Ask which California license they'll build your room under, then read that license class on the state licensing board's site. State law bars a residential remodeling contractor from contracting for structural work such as footings, foundations, load-bearing walls and roof structures. An awning contractor's license covers awnings and patio covers but not patio enclosures.
What is the difference between a sunroom, a solarium and a conservatory?
When the room is fully enclosed, heated and cooled, those names generally mean the same kind of room. What matters more is whether it has heating, cooling and insulated glass, because that's what separates a four season room from a three season one.
