Services in Whittier, CA

Four season sunrooms

Whittier summers turn a single-pane glass room into an oven by mid-afternoon, so most people who want to use the room in August end up asking about a four season sunroom. We build those with insulated glass and a roof that keeps the heat out, so the room works in July and December.

Patio-to-sunroom conversion

A lot of Whittier backyards already have a covered slab that only gets used for the grill. We check whether that slab can carry walls and a roof, add support where it can't, and close it in.

Deck-to-sunroom conversion

Sloped lots in the hills mean raised decks, and a deck built for people and a barbecue isn't automatically ready for a glass room. We look at the posts and footings first, and we only build on a deck that can take the extra weight.

Sunroom remodeling

Older sunrooms here tend to leak at the roof joints, fog up between the panes, or bake in the afternoon. We find out whether the trouble is the glass, the roof or what the room sits on, and fix that.

Patio cover installation

Sometimes you just want shade on a west-facing patio without closing it in. We set the posts and attach the cover to your house in a way that can be enclosed later if you change your mind.

Screen room installation

Screen rooms suit Whittier yards near trees and brush, where bugs come along with the shade. You get open air without the visitors, and it costs less than glass.

Whittier, CA properties and local conditions

The city's own findings say this corner of the county sees more high wind, earthquakes and fire than much of California, and a sunroom feels all of that because it's mostly glass on a light frame. We tie the frame into a base that can take the pull, so on most Whittier jobs I'm checking the slab or footings before anyone talks about windows.

Many of the patios we look at here were poured decades ago as a place for a grill, not a wall of glass. They're often thin, cracked or sloped back toward the house, which is fine for a lawn chair and not much else. When a slab won't hold, I tell you, and we add footings, the deeper concrete pads that carry the walls, or pour new before the room goes up. On the hillside lots to the north, the same question applies to deck posts.

Permits and licenses for a Whittier sunroom

Inside city limits, the city's Building & Safety Division issues the permit for a sunroom. In the unincorporated South Whittier-Sunshine Acres and West Whittier-Los Nietos areas, LA County Public Works issues it, so the first thing I do is look up which office handles your address. Either way, the permit comes before the building, and that review sets the front of the schedule. The city also requires a city business license from anyone working in Whittier, even a contractor based outside it, and it checks the contractor's state license number on that application, so ask anyone you're considering for both. We're licensed and fully insured, and when your job needs a permit, we handle the paperwork and work through the inspections with you.

The price mostly comes down to what the room sits on, how much glass you want and what kind, whether it's a three season room or one you heat and cool all year, and any electrical you add. The schedule turns on the permit review and on whether the base needs work first. Your written estimate gives you your own figures. Whittier is a short drive from our base in Hacienda Heights, and we do the same work on similar houses in El Monte and Norwalk.

How a sunroom job goes in Whittier

  1. Call and set a visit

    Call (626) 269-6285 or send the form, and we'll pick a time for me to come out. Plan to be home, because I'll want you there for the next part.

  2. Look, measure and ask questions

    I check the slab, deck or ground the room will sit on, measure, and ask how you plan to use it. You then get a written estimate, so you know the price before you sign anything.

  3. Sort out the permit side

    In the city, Planning Services looks at the project first, then Building & Safety checks the drawings, and inspectors visit as the work goes. We handle that paperwork and are there with you for the inspections.

  4. Build it and walk through

    My crew and I do the building ourselves. When it's done, I walk through the room with you before we call it finished.

Frequently asked questions

Do I need a permit to build a sunroom in Whittier?

Yes, building or enlarging a structure in Whittier takes a building permit, and adding a sunroom to your house does both. Most plumbing and electrical work needs a permit too, which matters if you want outlets, lights or a ceiling fan in the room. The city's plans examiners check the drawings against the current California building code before anything gets built.

When does a contractor need a state license in California?

A contractor needs a license from the state licensing board when the project needs a building permit, when it uses any other workers, or when the labor and materials total $1,000 or more. A sunroom meets all three, so whoever builds yours should be licensed. That's one more reason a cash deal with a guy and a truck isn't the bargain it looks like.

How does the new wildfire map affect a sunroom in Whittier?

It may affect what's required down the road, though it doesn't describe today's fire danger. The city says the state's updated map shows how likely wildfire is over the coming decades, based on vegetation, slope and climate, and that it may affect insurance, building codes and rules about cleared space around buildings going forward. We build to whatever the permit for your address requires when we pull it.

How much does a sunroom cost in Whittier?

I don't quote a sunroom over the phone, because the biggest swing in price is the slab or deck it sits on, and I need to see that. A sound slab with a simple three season room costs far less than a four season room that needs new footings, a matched roofline and new circuits. You get your number in the written estimate after I've looked.

How do I know if my patio slab can hold a sunroom?

You usually can't tell by looking, so I check it at the estimate. Cracks, sinking corners and a slope toward the house are warning signs, and a thin slab poured for patio furniture often needs footings at the edges before it can carry walls and a roof. If yours won't hold, I'll tell you before we price a room on top of it.

What is the best way to keep a sunroom cool in Whittier summers?

A solid insulated roof and better glass do most of the work, more than any fan will. A glass roof on a south- or west-facing room turns into a greenhouse by afternoon, so we usually steer people toward a solid roof with glass walls and insulated panes if they want to use the room in August. Shades and a way to let hot air out handle the rest.

About Whittier, CA

Whittier is older than most of the cities around it, and you see that on our jobs. The streets near Uptown have houses that go back a long way, the flatter south and west sides are mostly postwar tracts with slab patios out back, and the hills to the north have bigger lots that drop away behind the house. Each kind brings a different starting point for a sunroom.

It sits right beside Hacienda Heights, where we're based, so the ground and the houses are familiar. Old slabs on the flats and raised decks on the slopes decide most of what a Whittier sunroom job looks like before the glass ever shows up.
