Home Additions and Exterior Upgrades in Missouri City, TX
We add rooms onto existing homes in Missouri City, and we build the covered patios, pergolas and screen rooms that go out back. New siding is on the list too.
Home Additions
More Room Without Moving
When the family outgrows the house, moving isn’t the only option. An addition can give you another bedroom, a bigger living area or a home office, and you get to stay on the street you already know.
Inside, the new room gets the same insulation, drywall and finish work as the rest of the house. All-Tex is family owned and fully insured, with 35+ years of work on Houston area homes.
- A free meeting at the house to talk through the space
- The outside finished to match your brick or siding
- Permits taken care of as part of the job
- One project manager from start to finish

Common Questions
Home Addition Questions in Missouri City
Is Missouri City in your service area?
It is. Missouri City is part of the area we cover from our office in Spring.
Will the addition match the house?
That’s the goal on every one we build. We match the roof line, the brick or siding, and the trim.
Do you take care of permits?
Yes. We prepare what the job needs and get the permits before construction starts.
How much does an addition cost?
It depends on the size of the room and what goes inside it. After a free visit, we’ll put the full cost in writing.
Can I finance an addition?
Financing options are available. Ask about them when we come out.
Who do I talk to while it’s being built?
You’ll have a project manager dedicated to your home, and that’s who keeps you posted as the work goes along.
