Dealing with property development and industrial rules in Texas is never a simple task. If you are considering a new commercial site or securing construction permits, you must understand the environmental risks involved early on.
Contaminated soil, hazardous materials, and compliance issues can derail both budgets and timelines, turning a promising project into a costly delay. These are things even the top construction companies can’t find alone.
To help you avoid those setbacks, we researched leading experts in the region who specialize in navigating these challenges.
Here is our guide to the best environmental consulting agencies in San Antonio. These are for keeping projects compliant, safe, and on track from start to finish.
How much does environmental consulting cost in San Antonio?
The cost of environmental assessments in San Antonio typically ranges from $1,800 to over $15,000, depending on the site’s complexity and the level of testing required.
| Service Type | Typical Cost Range | Description |
| Phase I Environmental Site Assessment | $1,800 – $6,000+ | Entry-level assessment used in real estate due diligence. |
| Phase II Environmental Site Assessment | $5,000 – $15,000+ | Advanced assessment involving soil, groundwater, or vapor testing. |
1. Phase 1 Environmental Consulting

Website: https://phaseonereport.com/san-antonio-texas-phase-1-esa-company
Address: 100 E Houston St
Contact: (210) 972-3251
Hours: Monday – Saturday: 6:00 AM – 8:00 PM
Closing a property deal usually comes down to the wire, so having a consultant who respects tight deadlines is a total lifesaver. Phase 1 Environmental Consulting really stands out because it can deliver reports in just 24 to 72 hours.
For my last commercial purchase, their fast work kept everything on schedule. Even though they are a national company, they know the local South Texas and TCEQ rules inside and out.
Plus, their pricing is clear, which helps avoid any surprises.
Just keep in mind that they focus mostly on the first assessment. If they find any contamination, you will have to move into a Phase II evaluation.
That part naturally adds more time and expense to the project. Their initial speed is still hard to beat, though.
2. Astex Environmental Services

Website: https://astexinc.com/
Address: 139 Braniff Dr
Contact: (210) 828-9800
Hours: Monday – Friday: 9:00 AM – 5:00 PM
Industrial companies and federal contractors often need more than just a basic property inspection.
Since 1988, Astex Environmental Services has offered full-service consulting, covering everything from soil testing to full site remediation. Their work is often used on both commercial and government projects, depending on the scope.
They also take a practical approach to reporting, looking at projects from an owner or lender perspective. That means their findings also explain how it can affect costs and decision-making.
The main downside is that pricing isn’t always straightforward. Because many of their services require custom evaluations, especially for things like indoor air quality, getting an initial quote can take a bit longer than expected.
3. AEHS, Inc.

Website: https://www.aehs-sa.com/w/
Address: 4402 Centergate St
Contact: (210) 656-9300
Hours: Monday – Friday: 7:30 AM – 4:30 PM
Staying compliant with workplace safety and environmental rules takes careful planning. AEHS, Inc. helps with that by combining environmental consulting with certified OSHA training programs.
We spoke with a client who sent their facility team to a hazardous materials course, and the hands-on training helped improve their internal safety procedures afterward.
They also bundle a range of health and safety services in one place, which can be useful for organizations like hospitals or military facilities that need consistent compliance support.
Their experience with asbestos and indoor air quality is especially helpful when working with older buildings.
The main limitation is their strong focus on training and certification. Companies that are mainly looking for large-scale engineering work or purely advisory consulting may find that their training-heavy approach doesn’t fully match what they need.
Customer Reviews:
The staff are warm and accommodating
As always, looked forward to the refresher class. Seriously, absolutely no one wants to do refresher classes. Kelly Brown makes sure you’re aware of new twists that are always coming out of Austin. The staff are warm and accommodating. If you’re lucky, you’ll get a chance to see Ron Bishop during breaks. Yeah, I look forward to training. It’s a part of this business we’re in.

4. CJ Environmental Consulting, LLC.

Website: https://cjenviro.com/
Address: 26017 Timberline Dr
Contact: (210) 788-7330
Hours: Monday – Friday: 8:00 AM – 5:00 PM
Legal battles over land contamination really need an expert who can find the actual root cause of the problem. CJ Environmental Consulting stands out because they provide specialized forensic investigations alongside its regular compliance work.
They use a very data-driven approach with lab testing to give you solid evidence for insurance claims or court cases.
We like how they treat clients as long-term partners, offering support from the very first check to the final monitoring phase. This kind of ongoing support is great for developers and managers who need someone watching their back throughout a project.
Just remember that they focus mostly on the physical side of cleaning up hazards. If you need big-picture sustainability planning or corporate strategy, you will probably need to find a different advisor.
5. Clean Environments Inc.

Website: https://cleanenvironments.com/
Address: 2800 NE Interstate 410 Loop #105
Contact: (210) 349-7242
Hours: Monday – Friday: 8:00 AM – 5:00 PM
Older commercial properties often come with hidden issues that need quick, accurate assessment. Clean Environments Inc. brings more than 30 years of local experience to that kind of work.
They focus on hazardous materials and moisture mapping. This can be especially useful for public agencies and private investors managing older buildings.
Since they’re fully licensed in Texas, their mold, lead, and asbestos clearances meet required legal standards. They also operate across the Gulf Coast, which helps when working with larger property portfolios in multiple locations.
The main limitation is their scope. They concentrate on indoor environmental hazards and cleanup work, so if you’re looking for broader sustainability planning or high-level corporate strategy, their services may feel a bit too specialized.
Walked me through everything I need to do
I hired Clean Environments for a mold issue I was having on a rental property. They have been so helpful, and affordable too, as I didn’t want to break the bank for a rental! Mold can be scary, but these guys were very transparent and walked me through everything I need to do. Will be using them in the future!
