A room too hot to sit in
When the room bakes by early afternoon, the usual culprits are older glass and a thin roof, and swapping those is where most of the comfort comes back.
Sunroom too hot by noon, cold all winter or dripping at the seams? We rework the glass, roof and walls so you use it again.

Sunroom remodeling in Mission Viejo means reworking an older room's windows, walls, floor or roof so it's comfortable, dry and more energy efficient, and turning it into a room you'll actually sit in.
Most remodels I'm called out for start with a room nobody uses. It bakes by noon in summer, runs cold on winter evenings or drips at a seam when it rains, and the furniture out there just collects dust.
The price moves with the room's size, whether you're going three-season or four-season, how many windows and roof panels we replace, and whether the slab or deck underneath needs work. The schedule turns mostly on that base and on the city's permit and inspections. If your job needs a permit, we file it and book the inspections, and we're licensed and insured. The written estimate after my visit lays out your scope and your figure.
I come out to look at every job, so the person who measures and checks your base is the one who plans the remodel, and our own crew does the build.
A sunroom is only as good as the slab or deck under it, so I'd rather tell you on the first visit that it needs work than after new walls go up.
I'd rather plan the room you'll sit in every week than the biggest upgrade we could sell you, so the money goes where you'll feel it, usually the glass and roof.
I look at the windows, roof and walls together, because a room that's too hot, too cold or leaking usually has more than one cause, and fixing them one at a time means opening the room up twice. We fold the upgrades into one project, since insulated glass and insulation in the walls, floor and roof go in far easier while the room is open, and adding them later often costs more.
If you want to take out the slider and open the room to the house, we plan for that from the start. Under the national sunroom specification, a heated or cooled room that's open to the house counts as living space, so its windows have to meet tighter air, water and heat standards. The same specification wants every sunroom, even one on a slab or deck, to carry its loads in a continuous path down to the foundation, which is why I check that connection before anything else.
Not every room needs to become a four-season room. If you mostly want shade and a breeze without bugs, screen room installation can be the better fit, and if there's no room yet, just a patio you hardly use, a patio-to-sunroom conversion is the job instead.
When the room bakes by early afternoon, the usual culprits are older glass and a thin roof, and swapping those is where most of the comfort comes back.
Water at the seams usually means tired seals or panels, and a leak left alone can soak the floor and frame, so we find the source before we patch anything.
Turning a three-season room into a four-season one means new windows plus heating and cooling, so we price the whole change together instead of piece by piece.
Faded floors and tired trim make a room feel unfinished, and if we're already swapping glass or panels, doing the floor in the same project saves tearing it up later.
Send the form and we'll reply within one business day. I'll come measure, check the slab or deck and talk through room types, then we send a written estimate, free and with no obligation.
Know the room's rough size, whether it's screened, three-season or four-season today, and your address, so I can check your fire zone and come ready to measure.

Straight answers on room types, cost, city permits, fire zones and roof upkeep, the things people ask me most on a first visit.
A four-season room is generally heated and cooled with all-weather windows, while a three-season room generally isn't and has uninsulated windows or screens. Settle on the type first, because it decides the windows, heating and cooling your remodel needs. If you want to sit out there in August and January, I'd go four-season.
A sunroom or sun porch in Orange County usually costs about $120 to $200 per square foot, and that's the area's going range for the room, not our price. Larger rooms that need a foundation plus heating and air conditioning land at the higher end. On a remodel, the number turns on how much of your room we keep, so the written estimate after my visit gives your figure.
The City of Mission Viejo takes every permit and inspection request online, through its Client Self Service Online Portal on the city's Building Services page. Requests in before 4:00 PM get an inspection the next business day. If your remodel needs a permit, we file it, book the inspections and tell you early if the city needs anything from you.
It can, because the city uses its fire hazard maps to update its building codes and fire safety policies, though it says the maps aren't a measure of immediate fire risk. The latest maps changed Mission Viejo's Very High Fire Severity Zones and added High Fire Hazard Severity Zones. Check your address in the city's Interactive Map Viewer, and I'll look too when I come out.
Many insulated roof panels last 25 to 40 years or more with proper care, depending on sun exposure, the panel coatings and upkeep. For upkeep, one maker's owner guide suggests looking over the roof and gutters once a year and staying off the roof unless there's a reason to go up. If your panels leak or sag, the remodel is the time to replace them.
Leaks and failing seals usually spread with each rainy season, so the sooner I see your room, the more of it we can keep.
