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

Adding On

How an Addition Comes Together

An addition is a bigger project, so here’s the rough order of things.

1

We Plan the Space With You

We look at the house and the lot, talk about what the room is for, and work out where it fits best.

2

We Price It and Handle the Paperwork

You get a written price, and we take care of the permits before work begins.

3

We Build and Finish It

Our crew frames the room, gets it under roof and finishes it inside and out.

I’m very happy with the work done by All Tex Windows! They did an excellent job installing my sunroom. The team was professional, arrived on time, and followed up after the installation to make sure everything was done right. Highly recommend them for their quality work and great customer service!

I have been looking at getting an addition added to my house for several years. I never gave the go ahead to any other company because It didn’t feel right. Then I called All-Tex, Once Ben came out and looked over my house and the project that we wanted done, which was a 400 sqft addition to add 2 more rooms something just felt right. Ben was very professional and so was his crew lead by Romero. They did amazing work and my family couldn’t be happier. I will be doing more work with them in the future and I would recommend All-Tex to anyone.

We had a pergola installed. It’s absolutely beautiful! They were also so fast!! I was very concerned how it would attach to my flagstone patio but it was much better than I expected. I enthusiastically endorse their work. I’ll look to them first if I have similar work in the future.

We had a great experience with AllTex. From the first interaction, their team was professional, responsive, and honest about what needed to be done. They showed up when they said they would, communicated clearly throughout the process, and the quality of their work was excellent. It’s hard to find companies these days that operate with integrity and truly care about doing the job right—AllTex does exactly that. I would absolutely recommend them and wouldn’t hesitate to use them again.

Is Missouri City in your service area?

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.
