What is a three season sunroom, and is it right for your house?
A three season sunroom in Hacienda Heights is a glass-walled room with its own roof, added onto your house, usually over a patio, deck or slab, so you can enjoy the outdoors without the wind, dust and bugs. It isn't heated or cooled, so it's built for the mild months, not as another bedroom.
Most people call us because the patio gets good light and still sits empty, or because an old enclosure leaks and they want something that works. The price mostly turns on the size, what the room sits on and whether you go with single pane or insulated glass, and the schedule turns on that same base check plus the permit side for your address, which we handle. If you want a room you can heat and cool all year, that's a four season sunroom, so it's worth knowing which one you're after before we draw anything. The estimate puts your own number in writing.
How do you know a three season sunroom is the right fix?
A patio nobody sits on
If the furniture is always covered in dust and leaves and the cushions live in the garage, the space is usually fine and it's the wind and bugs that are winning. Every season you wait is another season of paying for a patio you only look at.
An old enclosure that leaks
Water showing up along the base or dripping at the roof panels usually means the drainage or the seals have given out. Left alone, it stains the slab, rots any wood it reaches and turns a small repair into a bigger one.
Cracks across the slab
A crack running across the patio slab, or an edge that's dropped, usually means the ground underneath has moved. Build glass walls on that and the doors stop closing right, so it's far cheaper to deal with it before the room goes up.
How we build three season sunrooms
This is a room for enjoying, not for heating and cooling, so the first thing I do is make sure you're happy with that before we build anything. Then I look hard at the slab, deck or patio underneath, because a sunroom is mostly glass resting on whatever's under it, and checking that now costs a lot less than fixing it later. After that we go over the glass so you aren't paying for more than you'll use, and then my crew and I set the frame and roof, hang the doors, put in the glass, run any basic wiring you've asked for and clean up before we leave.
Some patios don't need a full sunroom. A patio enclosure can close in the cover you already have, and if your roofline or yard calls for a shape that doesn't come standard, we build custom sunrooms to fit it.
Single pane glass
One sunroom maker offers single pane glass, and it suits a room you'll use mostly on spring and fall evenings or one that sits in shade, since you aren't asking the glass to do much. It costs less, and that money can go toward a better base or a bigger room.
Insulated Low-E glass
The same maker offers insulated glass with a Low-E coating and argon gas, in clear or bronze tint, and it suits a room that takes the afternoon sun. It holds back more of that heat than single pane, so the room stays comfortable later into the day.

(626) 269-6285Building a three season sunroom in Hacienda Heights
Hacienda Heights is unincorporated LA County, so for property here LA County Public Works issues the permit, and the county's local office will tell you what your project requires. If your address falls under a different office, that office handles it instead, so we confirm which one is yours first. On a permit job the county's plan check reviews the drawings against safety and building standards, and inspections make sure what we build matches the permit. We look up the office for your address, and when the job needs a permit, we take care of the paperwork and work through the inspections with you. It's also worth putting your address into the State Fire Marshal's map to see whether your lot sits in a Fire Hazard Severity Zone, since that's better known before plans are drawn.
Plenty of houses here are older ranch homes with a patio slab poured long before anyone pictured walls on it, and on hillside lots the yard often falls away from the house. So we check that slab or the ground under a deck before anything else, and we see the same thing on jobs in Whittier and La Puente.

Frequently asked questions
How much does a three season sunroom cost in Hacienda Heights?
A 200 sq ft three season sunroom in Los Angeles County usually costs about $17,000 to $38,000. One El Monte price report counted labor, standard materials, basic electrical and building onto an existing patio, deck or slab in its price, and listed insulation, heating and cooling, plumbing and permits as extra. Your own number comes in writing at the estimate.
Can you heat or cool a three season sunroom?
Plan on it staying a room without heating or cooling. The industry's sunroom specification classes a room enclosed with glass or plastic openings like this one as non-habitable and non-conditioned, so it isn't treated as a regular living room. If you need year-round comfort, a four season room is the better fit, and I'll tell you so at the estimate.
Who issues the permit for a sunroom in Hacienda Heights?
For property in unincorporated LA County, which includes Hacienda Heights, LA County Public Works issues it, and the county's local office tells you what your project requires. You can reach that office by phone or email through the county's Service Locator, or let us look it up for your address as part of the job.
How do I take care of a three season sunroom?
Keep the door and window tracks clean and the weep holes, the small drain holes at the bottom of the frame, clear so water can get out. One installer's guide says to use pure silicone spray on the tracks rather than an oil-based lubricant, since oil grabs dirt, and to look over the roof and gutters once a year. The same guide says to stay off the sunroom roof unless you have to, which is good advice for most roofs.
How do I know if my patio slab can hold a sunroom?
You usually can't tell from the top, which is why I look at it before we talk price. Cracks running across it, edges that have dropped and a slab poured thin for patio chairs are what I check for. Glass is good at a lot of things, but bending isn't one of them.
What is a three season sunroom made of?
Most sunrooms are framed in aluminum, though some are vinyl or fiberglass, and if you're leaning that way we also build vinyl sunrooms. One maker uses tempered glass in the windows and doors as standard, and it breaks into small, harmless pebble-like pieces instead of sharp shards.
