Home Additions
Home Additions in Houston, TX
More room for your family, built onto the home you already own. We plan it, frame it, finish it, and get it inspected. Family owned and working on Houston homes for 35+ years.
Room to Grow
Add the Space Your House Is Missing
The family grew. Work moved home. The house stayed the same size. Moving costs plenty and pulls you off a street you already like. Building on gives you the room you need and keeps you right where you are.
We build room additions and second story additions across greater Houston. Foundation, framing, wiring and plumbing, then insulation, drywall, paint and trim. When we finish, the new space reads like it was always part of the home.
- Room additions, second story additions, and expansions that push the footprint out
- Bedrooms, home offices, playrooms, or simply a living room that fits everybody
- We handle the foundation, framing, electrical, plumbing, and heating and air, so there’s one company to call
- We match the roof line, the siding and the trim so the addition doesn’t look bolted on

Addition Types
Pick the Addition That Fits Your Home
Every addition starts with how you want to use the space. We plan around that, then build it to fit the house you already have.
How It Works
From First Sketch to Final Inspection
An addition is the biggest project most homes ever see. We keep the steps clear so you always know what happens next.
Free In Home Consultation
We come out, look at the space and talk through how you want to use it. You’ll have a price in your hands before a single plan gets drawn.
Plans, Permits and Prep
We design the addition, pull the permits, clear the site, then open the wall where the new space ties into the house.
Build, Finish and Inspect
We lay the foundation, frame the room, run the wiring and plumbing, then insulate, hang drywall and do the finish work. The building department signs off before we call it finished.
A project manager stays on your job and keeps you posted, so the schedule never comes as a surprise.
One Contractor
One Company From the Permit to the Last Coat of Paint
An addition touches framing, roofing, siding, wiring and paint. All-Tex has handled all of it under one roof for 35+ years.

What It Costs
What Affects Your Home Addition Price
An addition is priced on how it meets the house you already have, and that’s different every time, so we only price it after we’ve seen your home.
Size and Layout
Square footage drives most of it. A simple shape costs less to build than a room full of corners and angles.
Foundation and Roof
New slab work and tying the new roof into the old one take time and skill. Both show up in the number.
Plumbing and Wiring
A bedroom needs far less plumbing and wiring than a space with a bathroom, a wet bar or a laundry hookup.
Finishes You Choose
Flooring, cabinets, countertops, windows and fixtures all come in a wide range of prices, and you decide where to spend.
Every home is different. Get your exact number with a free in home consultation.

Common Questions
What People Ask Before Adding On
How long does a home addition take?
That depends on the size of the space and how fast the permits come back. You get a schedule at the consultation, and we update you as each stage passes.
Do you pull the permits?
Yes. Plans and permits come before any demolition, and the local building department inspects the finished work before we call it done.
Will it match the rest of my house?
That’s the whole point. We match the roof line, the siding and the trim so the new space blends in instead of looking bolted on.
Does an addition add value?
Usable square footage lifts what a home is worth, and you get to enjoy the room while you live there. A real estate agent can tell you what it’s likely to add on your street.
What do people use the new room for?
Bedrooms, home offices, playrooms, bigger living rooms, and space for family who move in. Tell us how you want to use it and we plan around that.
Do you offer financing?
Financing options are available. Ask at your free consultation and we’ll walk you through what fits the project you have in mind.
More Questions
More About Home Additions
Where do we start?
With a free consultation at your home. We look at the space, listen to what you actually need, and price it before anything starts.
Can you build a second story?
Yes. When the lot leaves no room to build out, going up is often the answer. We look at the existing structure first and build to code.
Who is my point of contact?
You get your own project manager, so there’s one person to call, and you’ll hear from them as the job moves from framing through finish work.
How far do you travel?
We cover Houston and the surrounding areas, from Spring and The Woodlands out to Katy, Sugar Land and Kingwood.
