About Grand Terrace, CA

Grand Terrace is a small, mostly residential city just south of Colton, where we're based, and it sits between Colton and Riverside with Blue Mountain rising along its east side. Most of the homes we see here are single-family houses with backyards, and a lot of them have a patio that's never been more than a slab and a cover.

On our jobs here, the flatter streets tend to have patios that were built for shade and not much else, while yards closer to Blue Mountain can slope, so the back of the house may open onto a raised deck or a stepped yard. That's why the first thing I look at is what the room will sit on and where the water goes when it rains, because a level, well-drained base decides what kind of room makes sense for your house.

Services in Grand Terrace, CA

  • Patio-to-sunroom conversion

    Plenty of Grand Terrace backyards already have a slab and a cover, and closing that in is often the simplest way to gain a room. We check the slab and the cover first, then build walls, windows and a roof that work with what's there and replace what won't hold up.

  • Screen room installation

    If you want the evening air without the bugs, a screened room on your patio gets you there without the work of a full addition. We handle screen room installation from the footings up, anchoring the frame so the panels stay tight when the wind picks up.

  • Patio cover installation

    Older aluminum covers here tend to sag, rattle or leak where they meet the house, and that's one of the most common calls we get. We take the old one down and build a new cover tied properly into your roof line, and we can plan it so it's ready to close in later if you want a room someday.

  • Deck-to-sunroom conversion

    Where a yard slopes, a raised deck is sometimes the only flat outdoor space, and people want to roof it in and use it year-round. We check whether the deck framing and footings can carry walls and a roof before we plan anything, and rebuild what can't.

  • Sunroom remodeling

    Some rooms added years ago run too hot, leak at the roof or just never got used. We figure out why first, then replace the glass, roof panels or doors so the room works the way you hoped it would.

  • Four season sunrooms

    A four season room has insulated walls, roof and glass, so you can sit in it on a hot summer afternoon or a cold winter evening. We plan it as part of the house, with windows placed for how you'll use the room and a roof that meets your existing one cleanly.

Who signs off on a Grand Terrace sunroom, and what moves the price

In Grand Terrace, the city's Building and Safety Division issues building permits, reviews construction plans against local, state and federal rules, and answers questions about inspections and code. That review comes before our crew sets a post, so on a job that needs a permit, the schedule turns on how soon the plans are ready and how quickly the city approves them. When your project needs one, we confirm which office covers your address, draw up the plans, handle the paperwork and set up the inspections, so you're not the one chasing forms. Before you hire anyone, ask to see their California contractor license, and since the city lists a business license among the things businesses apply for, the city is the place to ask about that one. We're licensed and insured.

Price mostly comes down to the size and kind of room and what shape your slab or deck is in, and I put your own figure in the written estimate after I've seen the yard. Grand Terrace is a short drive from us, and the calls here sound a lot like the ones we get in Bloomington and Loma Linda, mostly tired patio covers and slabs people want to turn into a real room.

Grand Terrace, CA properties and local conditions

An earlier city ordinance describes Grand Terrace as prone to wind gusts of up to 95 mph, and you feel that on an open backyard patio. A sunroom or patio cover catches wind like a sail, so we pay close attention to how the posts are anchored, how the roof panels are fastened and how the whole room ties into your house, and we build to what the city's plan review asks for.

Many houses here have a slab that was poured years ago to hold up a simple cover, not a room with walls and glass. Before I plan anything, I check whether that slab is level, solid and draining away from the house, because a room set on a base that can't carry it is the job people end up paying for twice.

How a sunroom job goes when you call us in Grand Terrace

  1. Call or send a message

    Call (909) 679-6010 or send the form, and we'll find a time to come out that fits your week. It helps if you can be home for the visit, since I'll want to walk the yard with you.

  2. I visit and measure myself

    I look at your patio, deck or slab and where the room will meet the house, and I ask how you plan to use it. You get a written estimate that spells out what you're paying for, and I'll go over any part of it as many times as you'd like.

  3. We handle plans and permits

    When your project needs a permit, we prepare the plans and handle the paperwork with the city, and our crew starts once the plans are approved. That review is the one part of the schedule nobody can rush, so we get the plans in as soon as you're ready.

  4. Our crew builds, then walkthrough

    Our crew builds the room and we set up the inspections along the way, so you don't need to be home every day. When it's done, I walk through the finished room with you and answer anything you want to know.

Frequently asked questions

How do I request a building inspection in Grand Terrace?

Send your inspection request to the city at Inspections@grandterrace-ca.gov, and make sure you get a confirmation back, because the city asks you to. On the jobs we build, we set up the inspections for you.

When does a sunroom contractor need a California state license?

The Contractors State License Board requires a license whenever the project needs a building permit, uses any additional workers, or has contracts totaling $1,000 or more in labor and materials, which takes in just about any sunroom job. Contractors also have to be licensed before they submit a bid, so ask for the license before you take an estimate seriously.

How much can a contractor ask for up front on a sunroom in California?

The state board caps a down payment at $1,000 or 10 percent of the total contract price, whichever is less. After that, the other payments are listed in the contract and based on work already done or materials already delivered to your house.

Does a freestanding sunroom or screen room in Grand Terrace have to sit away from the house?

It may, because an earlier city ordinance required buildings to sit at least five feet from the main house or other existing structures, with attached patio covers, attached garages and attached accessory dwelling units excepted. That rule comes from a prior code cycle, so we ask the Building and Safety Division whether it still applies before we plan a room that doesn't attach to your house.

Will a sunroom addition in Grand Terrace need fire sprinklers?

Ask the city before you plan a large project, because an earlier ordinance required automatic fire sprinklers in all new houses and in existing houses being remodeled across at least half of their existing building area. The city now lists newer code editions, so the division is the one to say whether that rule still holds, and we raise it when we prepare plans for a big remodel.

What causes the price of a sunroom in Grand Terrace to go up or down?

The kind of room makes the biggest difference, since a screen room is a much simpler build than an insulated four season room with glass walls. After that it's whether your slab or deck needs work, whether an old cover has to come down, and how much framing and anchoring the room needs for the wind here, and you'll see each of those in your written estimate.
