1. SATX Remodeling
Website: https://www.satxremodeling.com/
Address: 703 Westfall Ave
Contact: (830) 428-5239
Hours: Monday-Friday: 9am to 5pm; Saturday: 10am to 2pm; Sunday: Closed
SATX Remodeling operates on a full design-to-finish model. With this, they manage everything from creating the unique layout to completing the actual construction.
They also act as a permit and code concierge, completely taking over the tedious paperwork required by the city office.
I spoke with a real estate investor who used their scalable crews, and she was thrilled with how quickly they expedited the framing to hit a tight rental deadline.
Because they specialize in complete home makeovers, their team easily handles the structural changes necessary for underground living spaces.
Since basements are quite rare in our area, you’ll need to book your project under their broader home addition services since they lack a dedicated sub-grade moisture-proofing category.
Customer Reviews
Mark lead this crew and he did phenomenal work. He paid tremendous attention to each and every detail, accommodated each of our requests throughout the project, and communicated with us at every step. We could not be happier with the way the floor and stairs turned out. I highly recommend this company for any remodeling projects.

SATX remodeling has been a wonderful partner with Tomball Controls. I have used them for many projects both large and small and they consistently hit it out of the ball park. Great work, good communication and always finish before deadlines. I stopped getting other quotes, I am confident they will do the best job at a competitive price.

2. Blue Horizon Service Pro Remodeling & Construction
Website: http://www.bluehorizonremodeling.com/
Address: 13426 Vista Del Prado
Contact: (210) 987-7076; [email protected]
Hours: Monday-Friday: 8:30 AM – 5:30 PM; Saturday-Sunday: Closed
Tackling an underground build demands an integrated approach to ensure nothing slips through the cracks.
Blue Horizon Service Pro Remodeling & Construction operates as a comprehensive one-stop shop. They tackle underground builds with an integrated approach.
For starters, they have in-house designers alongside licensed professionals to keep the entire process under one roof.
They also have a specialized foundational expertise that your new subterranean space remains stable and dry. It’s particularly beneficial given the shifting soil challenges in South Texas.
If you’re comparing renovation contractors for a massive upgrade, Blue Horizon’s material-first selection process guarantees your fixtures are handpicked by seasoned specialists rather than sourced from standard bulk inventory.
While they deliver exceptional structural results, you might experience team variability. Because they operate across four major Texas hubs, you’re not guaranteed the same local core crew that a smaller boutique firm provides.
Customer Reviews
The work was done on time, the quality was great, and they were super respectful about keeping the area clean and safe. What stood out most was how they took our ideas and added their own expertise to make the final result even better than we imagined.

Israel and his team were always professional. Gave a fair price estimate.
The work they have done is outstanding and amazing. Attention to detail, cleaning up the work side each day – very amazing! They ensured we were happy and confident in the decisions made regarding our renovation.
They finished 2 days early.
We surely will go with them for our next project

3. Big Leo’s Remodeling – San Antonio
Website: https://bigleosremodeling.com/
Address: 7550 I-10 Suite 800-075
Contact: (210) 875-1061; [email protected]
Hours: Monday-Friday: 8 AM–5 PM; Saturday: 8 AM–4 PM; Sunday: 11 AM–1 PM
Big Leo’s Remodeling stands out for offering comprehensive project guidance. They walk clients entirely through the initial dream phase, straight into the final execution.
They focus heavily on transformative interior remodels here. With this, you can rely on them to bring their high-impact design skills to your basement.
Because they cover surrounding areas like Boerne and Helotes, their regional expertise is impressive.
I recently recommended them to a friend who wanted to restructure a lower-level footprint, and she greatly appreciated their deep awareness of local limestone foundations.
Keep in mind that they manage these underground builds under their general interior remodeling umbrella. They don’t maintain a specific basement finishing service line, so you’ll have to request specialized moisture barriers during the initial consultation.
Customer Reviews
I had a fantastic experience with Big Leo’s. From start to finish, their team was professional, attentive, and dedicated to bringing my vision to life. They not only communicated openly, they worked efficiently to complete the updates quickly. The quality of their craftsmanship is exceptional, and my home now feels fresh, modern, and exactly how I envisioned. I highly recommend Cristela, she made this process a breeze and to anyone looking to update or improve their home they truly care about their clients and deliver outstanding results!

An excellent company to work with.

4. 1Choice Home Improvement San Antonio
Website: https://1choicehomeimprovement.com/
Address: 442 Northstar Dr
Contact: 210-987-8080; [email protected]
Hours: Available 24/7
Protecting an underground environment from unexpected dampness is a critical part of any successful build.
1Choice Home Improvement has deep local roots, so they thoroughly understand the specific foundation challenges unique to Bexar County.
Notably, they operate as a restoration-to-remodeling hybrid. You can count on their heavy-duty equipment to handle below-grade spaces prone to water damage.
They even offer round-the-clock emergency support, making them convenient for urgent plumbing issues during a massive basement renovation.
As a one-stop shop, they effortlessly handle complex electrical wiring and custom flooring without relying on multiple subcontractors.
On the downside, their incredibly wide service focus means they act as generalists. Your specific basement finishing requests will fall under standard room additions rather than a dedicated niche.
Customer Reviews
We are overjoyed that we chose this firm for our house improvement! They did an incredible job converting our home into something we adore. Throughout the process, their team was pleasant and polite, and they made sure to stay inside our budget. We definitely suggest them for all of your San Antonio home renovation needs!

5. Rhino Design Build, LLC
Website: https://rhinodesignbuild.com/
Address: 4335 Vance Jackson Rd
Contact: (210) 413-8789
Hours: Monday-Friday: 8 AM–5 PM; Saturday-Sunday: Closed
Founded by Sam Guedot, Rhino Design Build benefits from his direct owner-led quality control. Using this approach, they ensure that craftsmanship remains exceptionally high across every stage of the build.
It’s no wonder they have over 20 years of established local reputation, and their credibility in the market is incredibly strong.
Their one-stop design-build model is also a fantastic offering. With this, architectural planning and physical construction are tightly secured under a single contract.
I noticed that they’re especially great at complex renovations that require foundational adjustments.
Because their primary focus lies in major renovations, they’re generally not the right fit if you only need minor cosmetic updates or simple drywall patching.
Danny and his team are incredibly trustworthy and honest. Their work is thorough and complete and have become my go-to team. Can’t recommend highly enough and I look forward to the next time I get to work with them!
Updated: As I travel frequently for the Thunderbirds, Danny and his team continue to be my Go-To!!! Always crushing it!
