Single-family homes and backyards in Willowbrook

Willowbrook sits between Compton and our home base in Lynwood, CA, so it's one of the closest places we work. Most of the homes we visit here are single-family houses on their own lots, and the backyard usually already has a concrete patio, a cover or a wood deck.

The room usually starts from what's already in that backyard, so that's where I look first. A patio slab poured years ago for a table and chairs may be thin at the edges or sloped toward the house, and a deck may sit on footings sized for people rather than a roof. Older houses also have their own quirks where a new roof has to tie in, like low eaves or a stucco wall that's been patched a few times. Finding those things on the first visit decides whether we build on what's there or start fresh, and it's how we keep a new room from leaking or settling later.

Our services in Willowbrook, CA

  • A lot of Willowbrook backyards already have a concrete patio, and it's usually the simplest place to start a room because the floor is already there. We check the slab's thickness and edges first, since a patio poured for a barbecue wasn't always poured to hold up walls and a roof.

  • If you already have a patio cover you like, closing in the sides can give you a room without starting over. We build enclosed patio rooms with windows or screens on the open sides, after checking that the posts and beam can carry the added walls.

  • Older wood decks here often have soft boards or footings sized for people and a grill, not a roof. We look under the deck before anything else, and if the framing won't carry a room, I'll tell you so and show you what it would take.

  • A three season room suits families who want to use the space most of the year without paying for full insulation and a heating and cooling setup. It still keeps out wind, dust and rain, and I'll walk you through when a four season room is worth the extra.

  • Sometimes the right answer for a sunny backyard is shade, not walls. We build patio covers that keep the afternoon sun off the slab and can be closed in later if you decide you want a room.

  • We also get calls about older sunrooms and enclosed patios that leak at the roof seam, fog between the panes or get too hot to sit in. We find what's failing first, and I'll tell you honestly whether a repair makes sense or the room is better rebuilt.

What happens when you call us about a Willowbrook sunroom

  1. Call and set a visit

    You call (424) 296-8574 or send the form, and we pick a time for me to come out to your house in Willowbrook. Plan to be home for it, because how you want to use the room matters as much as the measurements.

  2. Measure the space and talk

    I measure the patio, deck or slab, check what it can carry and talk through which kind of room fits how you live. Then we write up an estimate that spells out what's in it, so you can see what you're paying for before you decide.

  3. Handle permits, then build

    When the job needs a permit, we prepare the drawings, handle the county application and line up the inspections, keeping you posted at each step. Our own crew builds the room under a lead installer, and I check in at each stage.

  4. Walk through the room together

    At the end we walk through the finished room with you, and I point out anything I'd want you to know about it. I'll show you how to look after it, like keeping the gutters and drain paths clear before the winter rains start.

Willowbrook sunroom questions answered

Who issues building permits for a sunroom in Willowbrook?

Los Angeles County Public Works issues them, because Willowbrook is unincorporated, outside any city, so the county acts as its local government. If you're not sure your address is in county territory, the county's Z-Net tool will tell you, and a property outside the county's jurisdiction may go to another office. When your job needs a permit, we prepare the drawings and handle the application with LA County Public Works for you.

Do I need a permit to add a sunroom or enclose a patio in Willowbrook?

Usually, yes, because the county's permit guidance covers new building, additions and alterations, and its examples name adding a room, patios, decks and even replacing windows. The county asks you to check with its local office about what your project requires, and its Service Locator lists that office's phone and email. I'll go over what your job likely needs at the estimate, and when it needs a permit, we take care of the paperwork.

When does a contractor need a California license to build a sunroom?

The state's Contractors State License Board requires a license when a job needs a building permit, uses any additional workers, or costs $1,000 or more in labor and materials. A sunroom almost always meets at least one of those, so whoever builds yours should hold a license. We're licensed and insured, and our own crew does the build.

How soon is the first inspection due after I get a permit in Willowbrook?

The county says to request the first inspection within 12 months of getting the permit. After that, follow-up inspections are scheduled every 6 months to keep the permit active. We line up the inspections and keep you posted at each one.

How much does a sunroom cost in Willowbrook?

The biggest things that set the price are the kind of room, its size and whether your slab or deck can carry it without new footings. A screen room or three season room usually costs less than a fully insulated four season room, and the glass, roof panels, electrical work and permit drawings all add to it. At the visit I measure and we write up an estimate that spells out what's in it, so you can see where each part of the price comes from.

What is the best way to choose between a screen room and a four season sunroom in Willowbrook?

Start with when you'll really use the room, because Willowbrook's weather is mild enough that many families don't need full insulation. Modeled estimates for the area, not weather station readings, put January highs near 67°F and August highs near 80°F, with about 3 inches of rain in each of January and February and essentially none in August. That's why I look first at shade and airflow for hot afternoons and at how the roof sheds those winter storms, and a three season room often covers what a family really wants.
