A Phase II isn’t something every property needs, but when a Phase I points to potential contamination, it’s the only way to get a definitive answer.
When a Phase I flags a concern, a Phase II ESA tells you exactly what you’re dealing with. All Sides Environmental handles the sampling, lab coordination, and reporting from start to finish.

A Phase II ESA moves beyond records and visual inspections into actual subsurface investigation. It involves collecting and analyzing soil, groundwater, or soil vapour samples to confirm or rule out contamination identified in a Phase I report.
If your Phase I came back with recognized environmental conditions (RECs), a Phase II gives you hard data, the kind lenders, attorneys, and buyers can actually act on.

We go over the Phase I report, identify which recognized environmental conditions warrant investigation, and design a targeted sampling plan that addresses the specific concerns on your property.

Our licensed team collects soil, groundwater, or vapor samples using minimally invasive methods. We document everything in the field so nothing is missed and the chain of custody stays intact.

All samples are sent to accredited third-party laboratories for analysis. We review the results against Texas TCEQ screening levels and assess what the data actually means for your property and intended use.

You receive a clear Phase II report explaining the findings, contamination levels, if any, regulatory implications, and recommended next steps, whether that’s remediation, a no-further-action letter, or something else entirely.


A Phase II ESA gives you something a Phase I can’t, confirmed data. With that data, you can renegotiate a purchase price, require the seller to remediate before closing, walk away from a bad deal, or move forward with full confidence.
Skipping a Phase II when one is recommended means taking on an unknown risk that could turn into a very expensive problem down the road.
No, a Phase II is only recommended when a Phase I identifies recognized environmental conditions that warrant further investigation. If your Phase I comes back clean, you’re done.
Timeline varies depending on the scope of sampling and lab turnaround, but most Phase II ESAs take 3–6 weeks from field work to final report delivery.
We use minimally invasive sampling methods wherever possible. Soil borings and groundwater monitoring wells are standard, but we coordinate access carefully and work to minimize disruption to existing structures or ongoing operations.
Confirmed contamination triggers a decision point, remediation, regulatory reporting, price renegotiation, or, in some cases, no action if levels fall below regulatory thresholds. The All Sides Environmental team will walk you through every option clearly before you make any decisions.
Absolutely. If contamination is confirmed, that’s leverage. Many buyers use Phase II findings to boost their position to negotiate a lower purchase price or require the seller to remediate before closing. Having the data in hand always puts you in a stronger position.





Customer
A tenant complained of headaches and a strange smell that no one else noticed. All Sides Environmental’s IAQ testing pinpointed elevated VOCs from new flooring adhesive, not mold or other previously considered issues. We fixed it fast, and the tenant stayed. Their expertise saved the relationship.

Customer
Our Phase I flagged a recognized environmental condition on a Houston-area tract. All Sides Environmental decoded complex Phase II findings into plain language, explaining exactly what contamination levels meant for our plans. This clarity helped us confidently decide whether to proceed, that’s rare expertise in this field.

Customer
Renovating a late-70s facility wing, our contractor required asbestos clearance. Dean’s team sampled floor tiles, ceiling material, and pipe insulation on short notice, delivering a report in four days, and flagged an area we’d overlooked. Their thoroughness saved us from a costly mid-renovation surprise.

Customer
Two companies gave us a clean bill of health, but something felt off. The All Sides team dug deeper and inspected longer. They used tools that looked inside the walls near our HVAC closet and found a hidden mold colony. All Sides oversaw remediation end-to-end, and we tested clean and received our clearance certificate within a week.

Customer
Three weeks from closing on a Katy strip mall, our lender suddenly required a Phase I ESA. All Sides scheduled us in two days, was on-site by Thursday, and delivered the report before our deadline. The lender accepted it without question, and I’ve since referred them twice.
