How do you know it's time for a custom sunroom?
A patio that sits empty
The chairs are out there, but nobody stays on that patio or slab for more than a few minutes. Usually it's too exposed or too cut off from the house to be comfortable, and every season you wait is another one where that space does nothing for you.
Everyone crowds one room
Homework, TV and guests all end up in the same living room because there's nowhere else to go. That usually means the house needs another room, and the longer it goes, the more the crowding wears on everyone.
An old enclosure wearing out
Screens are torn, panels have gone cloudy, or water and dust get in where they shouldn't. That usually means the room has reached the end of its life, and leaving it lets water work into the frame and the wall it's attached to.
What should I know before planning a custom sunroom in Lynwood?
A custom sunroom in Lynwood is a room we design around how you'll actually use it, then build onto your house over a patio, deck or slab. It can be a simple room with no heating or cooling, or one that's essentially the same as any other room addition, and that choice shapes most of the job. We're based in Lynwood and build across the cities around it, including South Gate, Compton, Downey and Long Beach.
Most people who call me have a patio or deck they want to turn into a room they'll use, so the first thing I look at is what they want the room for, because that decides the type. The price moves mostly with the size, whether the room gets its own heating or cooling, whether it opens into the house or stays closed off from it, and what's underneath it now. The schedule turns mostly on the city's plan review, and when a job needs a permit, we prepare the drawings and handle the application for you.
Details to note before an estimate
- Rough size of the patio or deck
- What's underneath now, slab or deck
- How your family will use the room
- Heating or cooling, or neither
How we plan and build your custom sunroom
Custom means the room fits your days, so I start by asking how you'll spend time in it, whether that's morning coffee, homework or a home office, and we sketch from there before anything gets drawn up. From that sketch we settle the type together. If you want heating or cooling but like your house the way it is, the room can have its own system and keep your existing doors and windows in place, which closes it off from the house. If you'd rather it open straight into your living room, you're really choosing a full room addition, which doesn't need that separation. Once the layout is set, we have the plans drafted on a computer, because Lynwood doesn't accept hand drawn plans, and we work in California's Energy Code requirements for additions, which cover energy and water efficiency and indoor air quality. Then our crew prepares the base, frames the room, sets the glass and roof, finishes the inside and cleans up before we hand it over.
Custom work connects to a couple of other jobs we do. If you've already settled on a design and just need it built, our sunroom construction work covers the build itself, and if you have an older sunroom that no longer suits you, sunroom remodeling can rework it so you don't start over.
Other sunroom work you might need
Sunroom construction
For when the plan is already settled and what you need now is a crew to frame, glaze and roof the room.
Sunroom remodeling
For when the room you have is sound but the glass, layout or finish no longer fits how you live.
What happens after you call us about a custom sunroom in Lynwood?
Call us and book a visit
You call or send the form, and we set a time for me to come see the space. I measure, look at what's underneath and listen to how you want to use the room.
Read your written estimate
We write up an estimate that spells out what's in it, from the room type and size to the glass, roof and any support work, so you can see where the money goes. You can ask about any line before you decide anything.
We handle drawings and permits
If the job needs a permit, we get Planning Division approval first, since Lynwood wants it before plans go to the Building Division, then we submit and line up the inspections. We keep you posted as each step comes back.
Build, check in, walk through
Our own crew builds the room, led by our lead installer, and I check in at each stage. At the end we walk through it together and I show you how to look after it.
Common questions about custom sunrooms
How much does a custom sunroom cost near Lynwood?
A sunroom addition in the Los Angeles area usually costs about $23,000 to $66,000 per job, for the whole addition. Where yours lands depends on the choices covered above, mainly size, heating or cooling and what the room sits on. The estimate I write after seeing your space gives you the figure for your own room.
Who reviews sunroom plans in Lynwood, CA?
Lynwood's Building and Safety Division reviews plans for any building or structure, and that includes a sunroom. If the work disturbs 25 yards or more of soil, it also needs a separate grading permit. We prepare the drawings and handle the application, but it's worth checking the current steps with the division, since its submittal list can change.
How do I know if my deck can hold a sunroom?
A sunroom can go on an existing deck, but the deck will typically need extra beams, posts or footings to carry the added weight. I check that on the first visit, and if your deck needs it, that structural work shows up in the estimate and the price.
How much can a contractor ask for up front on a sunroom in California?
In California, a down payment on a home improvement job should be no more than 10 percent of the contract price or $1,000, whichever is less. On a full sunroom addition, $1,000 is usually the lower figure, so that's the limit. We're licensed and insured, and if anyone asks you for more than that at signing, take it as a reason to slow down.
What should a sunroom contract in California include?
California requires a written contract for any home improvement job over $500 in combined labor and materials, which covers any sunroom. The contract also has to say in writing who will get the permits and give a completion date, so ask about both before you sign. I'd rather you understand every line than sign something you'll wonder about later.
How do I take care of a sunroom once it's built?
Most of the care is simple checking, and one sunroom maker's guide suggests inspecting the roof and gutters once a year. Keeping leaves and dirt off the roof and out of the gutters keeps water moving where it should instead of sitting against the frame.
