Sunroom Contractor in West Covina, CA - Rooms Built Level on Sloped Lots
Sunscape Whittier Sunrooms & Patios builds sunrooms, patio enclosures, screen rooms and patio covers for West Covina homes, turning the slab, patio or deck you already have into a room you can use more of the year.

West Covina's hillside lots and backyard slabs
West Covina sits in the San Gabriel Valley, with a busy shopping stretch along Interstate 10 and blocks of single-family houses spreading out from it, some on flat ground and some climbing into the San Jose Hills. Most of the calls we get here come from homeowners with a concrete patio or an older wood deck out back that's too hot in August and too chilly in January to get much use. The work is a lot like what we do next door in Hacienda Heights and El Monte, but the slope on many lots here changes how we plan the job.
On a sloped yard, the room has to sit level even when the ground doesn't, so I look hard at the slab, the drainage and the spot where the room meets your house before we talk about glass or finishes. Those are the parts nobody sees once the room is done, and they decide whether it stays square.

Sunroom work we do in West Covina
Patio enclosures
A lot of West Covina houses already have a covered patio that just needs walls to become usable space. We frame and glaze it to fit the cover you have, or tell you plainly if the cover won't carry the load.
Patio-to-sunroom conversion
Older backyard slabs here are often cracked or pitched for runoff, which is fine for a patio and wrong for a room. We check the slab first so the new floor comes out flat and the water still drains away from your house.
Sunroom remodeling
Some sunrooms around town leak at the roof line or cook in the afternoon because of the glass they were built with. Our sunroom remodeling work fixes the tie-in to the house first, then updates the panels so the room is comfortable again.
Patio cover installation
Valley summers make shade the first thing many homeowners here want out back. We set the posts and attach the cover so you can enclose it later without starting over.
Deck-to-sunroom conversion
On hillside lots the deck is often the only flat outdoor space, and a deck built for chairs isn't always built for a roof and walls. We open it up, look at the framing and footings, and reinforce what's needed before the room goes on.
Four season sunrooms
If you want the room usable on the hottest days, not just in spring, you need insulated walls, a solid roof and the right glass. We walk you through those choices so you know what you're paying for and why.
Building a sunroom in West Covina, from permit to price
Permits for private work in West Covina come from the city's Building Division, which checks plans against the California building codes, so plan check and inspections usually set the pace more than our crew does. We check your address early so we know whether the city or the county is handling the job, then we take care of the permit paperwork, meet the inspector for each visit and keep you posted on where things stand. The city also requires any business working in West Covina to hold a city business license, due within fifteen days of starting there, so it's fair to ask any contractor you're considering whether they have one. We're licensed and insured.
What moves the price is mostly the room's size, glass or screen walls, whether your slab or deck can carry the room or needs new footings, and how much work the roof tie-in takes. The schedule turns on the city's review, inspection timing and how long the materials take to arrive. On hillside streets I also plan how materials get from the curb to your backyard, because a steep driveway or a narrow side yard adds time. As a sunroom contractor in Whittier, CA, we bring the same careful approach here that we use in Downey and the other cities around us, and your written estimate spells out what drives the price for your house.

Sunroom ideas for West Covina homes
Sunroom questions from West Covina homeowners
What is the best way to find out if my sunroom needs a permit in West Covina?
Ask the city's Building Division, because sunrooms and patio enclosures aren't on the city's list of work that can skip a building permit. That list covers things like small sheds, fences, low decks and finish work, and it notes that electrical or plumbing permits may still be needed for related work. We check your address early and handle the permit paperwork for you.
How do I apply for a building permit in West Covina?
You apply through the city's One Stop Building Permit Center, since the Building Division no longer takes applications by email. The Building Counter at City Hall also takes applications in person Monday through Thursday, 7:30 am to 5:30 pm, and you can call the division at (626) 939-8425 with questions. On our jobs, we take care of that filing and meet the inspector ourselves.
Does a project that doesn't need a building permit still need Planning approval in West Covina?
It can, because the city's Planning Division may still need to approve work the Building Division doesn't permit. In some cases Planning can limit where a structure goes and how tall it is, and set design requirements. Their counter is at City Hall, phone (626) 939-8422, and I'd rather find that out before we draw anything up.
Can I enclose my deck in West Covina without a permit?
Don't count on it, because the city's exemption is for a deck itself, and only one no more than 30 inches above grade with no story below and no accessible route across it. Adding walls and a roof makes it a different project, so we check with the Building Division before any work starts. We also look at the deck's framing, since many weren't built to carry a room.
How much does a sunroom cost in West Covina?
The price comes down to the room's size, glass or screen walls, the condition of the slab or deck it sits on, and how much work it takes to tie the roof into your house. Sloped lots that need more work on the base, insulated walls and added electrical all raise it, while enclosing a sound existing cover usually keeps it lower. I'll give you a written figure for your own house after the free estimate visit.
Does a contractor need a city business license to work in West Covina?
Yes, the city requires any business operating in West Covina to get a city business license, due within fifteen days of starting work there. The city's Finance Department handles business licensing. It's a reasonable thing to ask any contractor before you sign.
