How do you know you need an all season room?
Patio chairs nobody uses
You've got chairs and a table out back, but by midafternoon it's too hot and after dark it's too cool, so everyone stays inside. That usually means the space needs walls, a real roof and heating and cooling, and every year it waits is another year of yard you're paying for and not using.
A sunroom you avoid in summer
If you already have a glassed-in room that bakes on summer afternoons or turns chilly at night, it was likely built without insulation or heating and cooling. Living with it means a room you paid for sits closed most of the year, and fans and space heaters on extension cords only patch the problem.
Not enough room inside
When homework, a home office and visiting family are all fighting over the same table, the house is short a room. An all season room can add that space where your patio or slab already sits, and putting it off usually just means another year of everyone working around each other.
What is an all season room, and is it right for your house?
An all season room is an addition built into your house, with insulation, wiring and its own heating and cooling, so you can use it comfortably in every month of the year. We build all season rooms in Lynwood, CA, and what you end up with is a room of the house itself, not a covered patio with walls around it.
Most people who call us from Lynwood, South Gate, Compton, Downey, Long Beach and the cities around it have a patio, slab or deck out back that they'd like to turn into a room the family actually uses, and I've been helping them work out which kind of room fits since 2013. On an all season room the price mostly moves with the size, the materials and whether it needs a new foundation, while the schedule turns on the drawings and the permit review, and we handle that paperwork for you. Your estimate spells out what's in it, so you can see what each choice adds before you sign anything.
Details to note before an estimate
- Rough size of the room you want
- Patio, slab or deck it would sit on
- Cracks or soft spots in that surface
- How your family plans to use it
How we build an all season room
Before anything gets drawn, I sit down with you and settle whether the room gets heated and cooled along with the house, because that one choice decides the insulation, the wiring and the kind of windows the room needs. Next we look at what the room will sit on, whether that's an old slab, a patio or open ground, since that tells us if the plan starts with a new foundation. From there our crew frames the room and joins it to your house, insulates the walls and roof, runs the electrical, sets the windows and doors, puts in the heating and cooling, finishes the inside and cleans up the site.
Some people find partway through the conversation that they want something different. An enclosed patio room closes in the space you already have without making it part of the house, and solarium installation is the pick when you want glass overhead as well as on the walls. We're licensed and insured on all of it. Your satisfaction, guaranteed.

What happens after you call about an all season room?
Call or send the form
Call (424) 296-8574 or send the form, and we'll set a time for me to come out to your house. We pick up seven days a week, until 9 PM every night.
I come out and measure
I see the space, take measurements and listen to how you want to use the room, then we write up an estimate that spells out what's in it. You'll see what the size, the glass and frames, the foundation work and the heating and cooling each cover, so the price isn't a mystery.
We build and walk through
When the job needs a permit, we prepare the drawings, handle the application with the city or county office for your address and line up the inspections, then our own crew builds it under a lead installer while I check in at each stage. At the end we walk through the room together and I show you how to look after it.
Questions before you book an all season room
How do I decide between an all season room and a three season room?
An all season room is insulated and heated and cooled as part of your house, while a three season room is enclosed with glass but has no insulation and no heating and cooling. If you want to sit in it comfortably on a hot August afternoon and a cool winter night, the all season build is the one. If you'll mostly use it in mild weather, a three season sunroom may be all you need.
How much does an all season room cost in the Los Angeles area?
A sunroom addition in the Los Angeles area usually costs about $23,000 to $66,000 for the whole job, and an all season room is built as that kind of addition. Where yours lands comes down to the size, materials and foundation I mentioned above, and your written estimate breaks those out for your house.
Who issues building permits for a sunroom in Lynwood, and what comes first?
The City of Lynwood's Building and Safety Division issues building permits and reviews plans for any building or structure in the city, and the first step on its list is a plan check form with Planning Division approval attached before plans go to the building side. The city also lists plans drawn on a computer, not by hand, a structural plan with calculations unless the building official waives it, and energy calculations made part of the plans, plus a separate grading permit if the work disturbs 25 yards of soil or more. We prepare the drawings and handle that application for you, and the division can tell you what's on its current list.
Can an all season room be built on my existing patio or deck?
Sometimes, because prefab sunroom kits can attach to an existing wooden deck or a patio with a level surface, but a site-built room needs a proper building foundation of its own. That's why I check whether your slab or deck is level and sound on the first visit, since it decides whether the plan includes new foundation work.
What is the best way to choose windows for an all season room?
Look for two or three panes of glass with argon or krypton gas between them, which insulates better than air, set in insulated frames of wood, fiberglass or vinyl because those materials don't conduct heat well. In a room that's mostly glass, that choice does a lot of the work of keeping it comfortable, so we go over frame material with you along with the look you want.
Should an all season room be open to the house or closed off?
Either can work, but decide early, because sunroom standards treat a heated or cooled room that's open to the house as living space and one closed off with its own controls as separate from it. That choice changes how the room joins your house, so it's one of the first things we talk through with you.
