Backyards and patio slabs across Duarte

Duarte is mostly a city of single-family houses, a lot of them one-story homes with a concrete slab off the back door, often under an aluminum patio cover that's been up for years. People here usually call us because they already use that space and want it closed in with glass, screens or walls so it works as a real room. The houses and backyards look a lot like what we find next door in Azusa, and we start the job the same way.

Those older slabs are what I watch. Many were poured for a grill and some chairs, not for walls and a roof, and they can be thin at the edges, out of level or sloped back toward the house, so I check the slab before any room gets planned on top of it.

Permits and licenses for a sunroom in Duarte

In Duarte, building permits come from the city's Building & Safety Division, which covers building, enlarging, altering or converting a structure, and applications go in person to the Community Development Department at City Hall. Our crew can't start until that permit is in hand, so it usually sets the start date more than our calendar does. Before you hire anyone, it's worth checking two things, a California contractor license and a City of Duarte business license, which the city requires of every business working here. We're licensed and insured, and before work starts we check whether your address goes through the city or L.A. County and take care of the permit paperwork when the job calls for one.

What moves the price is the room type, from a screen room up to a fully closed four season room, plus the size, the glass, whether the room opens into the house and what the slab or deck needs before anything sits on it. The schedule turns on the permit and on parts, which we don't order until the measurements are checked, and you get your own figure in a written estimate after I've been out. It's the same careful start we use in Valinda and the other cities around Baldwin Park.

Services in Duarte, CA

  • Patio-to-sunroom conversion

    Plenty of Duarte backyards already have a slab off the back door, and a patio-to-sunroom conversion turns that slab into a room you'll use. I check its thickness, level and edges first, because the walls and glass sit right on it.

  • Patio enclosures

    Many houses here have an older patio cover that's still sound overhead but open on the sides. We enclose it with walls, windows and a door when the posts and roof can carry it, and if they can't, you'll hear that at the estimate.

  • Screen room installation

    Some homeowners want air and shade off the kitchen or family room without closing it in with glass. A screen room keeps the bugs out and is a lighter build than a glass room, so it often costs less.

  • Three season sunrooms

    A three season room closes a patio in with glass but isn't built to be heated and cooled like the rest of the house. It suits a back room you'll use most of the year, and it keeps the cost below a fully insulated room.

  • Four season sunrooms

    When you want a room that works like part of the house, with insulated walls and glass, a four season room is the build. It often opens straight into a family room, so we take extra care where it meets the house wall.

  • Deck-to-sunroom conversion

    Some houses here have a wood deck off the back instead of a slab. I check the framing and footings underneath before anything is planned, because a deck built for chairs often isn't built to carry walls and a roof.

What happens after you call us about a Duarte sunroom

  1. Call or send the form

    You reach us at (626) 869-2042 or through the form, and we set a time for me to come out to your house. It helps if you're home so we can stand at the spot together.

  2. I measure and check underneath

    I measure the spot myself and check the slab or deck the room will sit on, because that decides whether it ends up square and sealed at the edges. Nothing gets ordered from a guess.

  3. Talk through the room and glass

    We go over the room type, the glass and whether it opens into the house, and then you get a written estimate. You see the price on paper before you decide anything.

  4. Permits first, then we build

    Once you're ready, we sort out what the city or county asks for at your address. Then our own crew builds the room.

Common questions

  • Do I need a permit to enclose a patio in Duarte?

    Yes, plan on a building permit, because the city lists enclosing a patio among the jobs its building permit covers. A sunroom that adds onto the house falls under the same permit for enlarging or altering a structure.

  • How do I know if my Duarte home is under city or county permits?

    Check where your house sits, because some Duarte mailing addresses are outside the city's jurisdiction, generally west of Mountain Avenue and south of Duarte Road. The city sends those owners to the L.A. County Department of Building and Safety at 626-574-0941. I check which side your address falls on before we plan the job.

  • Does a sunroom contractor in Duarte need a California license?

    Yes, because the Contractors State License Board licenses anyone who builds or alters structures in California, and the license applies when a job needs a building permit, uses employees, or runs $1,000 or more in labor and materials. A home improvement contractor has to hold that license before giving you a bid, so ask for it before you take one.

  • Does a sunroom in Duarte need tempered glass?

    It does if your house is in a High Fire Hazard Severity Zone, because the city's code text calls for tempered glazing there. CAL FIRE has updated the hazard maps for Southern California, the city has to adopt them, and the changes can only raise a zone's rating, so a house that was outside a zone before may be inside one now. I check where your address falls before we choose the glass.

  • What affects the cost of a sunroom in Duarte?

    The room type, its size and the glass move the price most, with a screen room at the lower end and an insulated four season room at the higher end. What the slab or deck needs, whether the room opens into the house and the fire-zone glass rule, if it applies to you, add to it. Lights or a ceiling fan also mean a separate electrical permit, because the city's building permit doesn't cover electrical work, and your own figure comes in the written estimate after I measure.

  • How do I trim a tree over my patio in Duarte before a sunroom goes in?

    Normal seasonal trimming of less than a quarter of the tree's foliage is allowed without a permit, as long as it follows ANSI 300A pruning standards. Cutting back more than that, or removing an oak or any other tree on your property, takes a city-approved Tree Permit. I note anything hanging over the spot when I measure, so you know before the build whether a tree is in the way.
