Sunroom Contractor in Glendora, CA - Rooms That Shed Water and Close Right
Rancho Cucamonga Sunrooms & Patios builds sunrooms, patio enclosures and patio covers in Glendora, CA, and fixes the rooms that were put up in a hurry. I come out myself, and our own crew does the building.
Glendora: foothill lots and older patios
Glendora runs from flatter streets on the south side up into the foothills, and a lot of backyards here look out at open hillside. Most of what we work on is single-family houses, many with a patio cover or enclosure somebody added years ago, and plenty of yards that step down a slope. In that way it reminds me of Highland, another city where the houses back up to the hills, more than the flat lots we build on down in the valley.
That shapes the job. On a sloped yard the slab or deck under a new room often isn't level, and an old cover tied into the house is usually where the water gets in, so I look at both before I price anything.

Sunroom work we do in Glendora
Patio enclosures
A lot of Glendora backyards already have a patio cover and a slab, so closing it in is often the quickest way to get a room you can use. We check the slab and the cover first, because an enclosure is only as solid as what it's hung on.
All season rooms
If you want a room you'll use every month of the year, an all season room is the one to build. We frame it like part of the house, with insulated walls and roof, so it ties into your home instead of hanging off it.
Patio cover installation
Plenty of houses here have a tired aluminum cover out back that sags or drips where it meets the wall. We take it down, fix whatever it damaged and put up a new cover that sends water away from the house.
Deck-to-sunroom conversion
On a sloped foothill lot the back of the house often sits up on a deck instead of a slab. Before we put a room on it, we check that the posts and framing can carry the weight, and we rebuild what can't.
Sunroom remodeling
Some calls are about a room someone built in a hurry, with doors that stick and stains on the ceiling. We open it up until we find the cause, then fix the room instead of covering the problem with trim.
Screen room installation
When your yard looks out at the hills, a screen room lets you sit out back without walling off the view. It's the lighter choice, and we build it so it can be glassed in later if you change your mind.
Working in Glendora: permits, licenses and price
Glendora's own Building & Safety Division issues building permits and does the inspections, so when a sunroom needs a permit, the city's review and inspection dates set part of the schedule, not just our crew. Before we start, we check what the city wants for your address, and when a permit is needed we pull it and work with the building office through each inspection. The city also requires every business working inside city limits to hold a Glendora business license and pay business license tax before it starts, so that's a fair question to put to any contractor you're talking to. We're licensed and insured.
We're a sunroom contractor in Rancho Cucamonga, CA, and Glendora is a short drive west for us, the same kind of work we do in Upland and Pomona. What moves the price here is the size of the room, the kind of room you want and how much of the old cover, slab or deck has to be fixed first. I'll come out, measure and put your price in writing.

Sunroom ideas for Glendora homes
Glendora sunroom questions
How do I apply for a building permit for a sunroom in Glendora?
Building permit applications in Glendora go through the city's online Civic Access portal, and the city no longer takes them by email. You need an account to start one, and the portal is where plans get uploaded, review status gets tracked and inspections get scheduled. When your job needs a permit, we pull it and handle that side with the city.
How do I find out if my Glendora home is in a fire hazard severity zone?
Ask the city, because the City Council adopted a fire hazard severity zone map recommended by the state fire agency, and your zone depends on where your lot sits. In a March 2025 update, before the map was adopted, the city reported 5,149 acres as very high, 578 as high and 555 as moderate, so a good part of Glendora is on it. You can check your property's zone with the city, and it's worth having when I come out, since we check what the city wants for your address before we start.
How much does a sunroom cost in Glendora?
There's no honest number until I've seen your house, because the price comes down to the size of the room, the walls and glass you pick and what's already under it. A screen room or three season room costs less than an all season room built to live in, and an old cover or slab that can't carry a new room adds tear-out and rebuild work. Call (909) 360-4006 and I'll come take a look.
How long does a sunroom project take in Glendora?
The schedule turns mostly on the permit and on what's under your patio. The city's review and inspections come before and during the build, and a room on a sound slab moves faster than one where we find rot or a bad slab once the old cover comes off. I'll tell you what I expect once I've seen what's there.
What causes an old patio enclosure to leak?
Most old enclosures leak where they meet the house, because the cover was hung on the wall or roof edge without proper flashing, the metal that steers water away from the joint. I spent years fixing those, and a lot of them had the problem hidden under trim. We tie a new room in so water runs off where it should, and we don't cover a bad joint up.
What happens to the debris when you tear out an old patio cover in Glendora?
We haul off what we tear out and clean up before we leave. The city's Building and Safety page says that under state law, construction and demolition projects have to recycle or reuse 65% of their waste, and covered projects have to turn in a waste management plan. If your job counts as one, we sort that out with the city along with the permit.
