Raleigh has the largest pre-1989 housing inventory in the Triangle — tens of thousands of homes built during the popcorn-ceiling, vinyl-floor-tile, and asbestos-pipe-wrap era. Most of what we test still falls into that window.
Asbestos testing is not the inspection and it is not the removal. It is the laboratory analysis of physical samples — bulk material under polarized light, airborne fibers under phase contrast or electron microscopy — performed by an AIHA- or NVLAP-accredited lab and delivered in a certified written report.
Every step of that chain has to hold up. Sample location, collection technique, chain of custody, lab accreditation, method citation, and report format all have to survive scrutiny from a permit reviewer, a buyer’s attorney, or an insurance adjuster. We do testing that holds.
Three failure modes show up over and over on Raleigh projects that arrive at our door for a re-test.
Popcorn ceilings, drywall mud, vinyl floor tile, mastic, pipe wrap, and siding all read differently under PLM. A sample pulled from the wrong layer or the wrong homogeneous area produces a result that doesn’t answer the actual question.
Lenders, NC DHHS, EPA NESHAP officers, and insurance carriers reject results that don’t carry an AIHA or NVLAP accreditation number. A cheap result from an unaccredited lab is worse than no result at all — it gives a false sense of finality.
If a sampling event isn’t paired with a signed, dated, method-cited report, you have nothing to hand a buyer, a permit reviewer, or a future regulator. Documentation is the deliverable.
We don’t guess at homogeneous areas, we don’t cut corners on chain of custody, and we don’t hand back a one-line lab printout and call it a report.
We walk the property with the client, identify suspect materials, define homogeneous areas, and confirm the regulatory driver — pre-renovation, pre-demo, real-estate due diligence, or post-abatement clearance — before a single sample is collected.
Bulk samples for PLM are wetted, double-bagged, photographed in place, and entered into a written chain-of-custody log. Air samples for PCM or TEM are pulled on calibrated pumps using NIOSH-validated methods at the correct flow rates and volumes.
Samples ship under sealed chain of custody to an AIHA- or NVLAP-accredited laboratory. PLM identifies asbestos in bulk by morphology and optical properties; PCM counts airborne fibers; TEM provides the definitive electron-microscopy confirmation when stakes or thresholds demand it.
Every project closes with a signed report — sample IDs, method, lab accreditation number, percent or fiber count, plain-language interpretation, and chain of custody attached. Formatted for permit reviewers, lenders, and insurers.
Real reviews from homeowners and contractors across North Carolina.
“We bought a new to us 1964 home last December and to no surprise, we had asbestos popcorn ceilings. We decided to remove the ceilings altogether versus just scraping them. To complicate things even more, we had a plumbing leak in a room that had previously been encapsulated, so we had to deal with insurance to cover a portion of the asbestos removal. Rusty and the whole team at Remtech were such a help from the first moment we spoke! They were responsive, flexible, and knowledgeable. They helped us get insurance what they needed. They even worked with us to do the removal work while we had to be out of town. Asbestos removal and dealing with insurance, especially as we were brand new to the home, was incredibly stressful. Working with Remtech was the opposite – they were helpful and easy to work with that I barely had to think about the work being done. It was a nice break for my brain! They also did a great job. We came home to a CLEAN house with no ceilings! While I’m hoping we never have to go through such a big project again, I know we’d be able to handle it because we can rely on Remtech.”
“Very fast, professional and responsive. Did floor asbestos abatement for our house for a very reasonable price and they were very quick to schedule to keep us within our very close timeline.”
“As a General Contractor specializing in Bathroom & Kitchen remodel, we complete in excess of 250 bathroom upgrades each year. Regardless of our remodeling and construction experience and capabilities, when it comes to addressing the unforeseen hazardous and environmental conditions posed by mold, asbestos, and lead paints, we have a responsibility to our customers to partner with the best abatement specialist possible, and as proficient in abatement as we are kitchen and bath remodeling. Remtech has proven to be that reliable and trusted partner for both our customers and company. We highly recommend the Remtech Team.”
“A few months ago I used Remtech Envir. to remove asbestos from the ceiling of my home, and to this day I’m still amazed with their service that I’ve been meaning to write a review, and today’s the day! The whole process went through so smoothly because of their professionalism, punctuality and care. At the end of each day I received an update from Rusty who was the project manager which was super helpful, and because of their expertise I knew the job was getting done correctly. There was a lot of asbestos to remove, and they showed up and delivered hard work to get it done within the time frame that was initially discussed. So grateful we used their services! I would highly recommend!”
“Our church basement flooded and the old asbestos tiles curled up and had to be removed. Jeff Brewer came over to look at our problem, explained what they would do. He furnished a quote very quickly with a fair price. After checking with two other companies, Jeff’s instructive conversation, ease of manner, willingness to help and a fair price won him the work. As a former contractor, I know how backed up companies can be in their schedule. He told us of a target time about 4-6 weeks off, which was fine. He called a couple of weeks later and had an opening in his schedule and wanted to come earlier. That was great. Their staff arrived on time and delivered a very quick, professional and clean project. This allowed us to get our Fellowship Hall floored and back in operating condition prior to the start of the school year. It is a pleasure to work with a company that communicates well and delivers their service in a superior way.”
“I have spoken with Bryan on many occasions about growth strategy. He has always been open to communicate. I look forward to future conversations.”
“Remtech came in and did a removal of asbestos when our home developed a leak and the sheetrock ceiling had to be removed. Got right to work, kept us informed every step of the way and did a great job of cleaning up. Would use them again in a heart beat!!”
“The cost was higher than expected, so I did not move forward at that time. I will use Remtech when I am ready to have the work done. They are very professional and take the time to answer any questions. The rep arrived on time, explained the process and provided the estimate. A very positive experience.”
A positive result triggers an inspection scope and an abatement plan. A pre-renovation survey often uncovers moisture damage alongside suspect materials. We address it all under one roof.
After two decades of Triangle sampling work, the same five questions come up. Here’s the short version — the long version is a phone call.
PLM (polarized light microscopy) is for solid bulk samples — popcorn ceiling, vinyl tile, joint compound. It identifies asbestos by morphology and optical properties down to roughly 1% by weight. PCM (phase contrast microscopy) is for air samples and counts fibers, but it cannot tell asbestos from other fibers. TEM (transmission electron microscopy) is the definitive method — it identifies individual asbestos fibers by morphology, electron diffraction, and elemental analysis. AHERA clearance and low-percentage bulk confirmations are TEM-only.
AHERA sets the floor: three samples per homogeneous area for surfacing material under 1,000 square feet, five up to 5,000, seven above. Thermal system insulation is three per homogeneous area. Miscellaneous materials are sampled to be representative. A single sample of a popcorn ceiling is statistically meaningless — asbestos distribution within a single material can be highly non-uniform.
Standard turnaround on bulk PLM is three to five business days. Same-day, 24-hour, and one-hour rush options exist at premium rates for closings, permit deadlines, and clearance work. Air PCM is typically same-day to next-day. TEM runs three to seven days standard. We recommend planning around standard turnaround and reserving rush for genuine schedule pressure.
Clearance proves that, at the moment of sampling, airborne fiber concentrations inside the previously contained work area are below the regulatory threshold — 0.01 f/cc for PCM, or 70 structures per square millimeter under AHERA for TEM. It is required by NC 15A NCAC 19C and AHERA before reoccupancy. The clearance must be performed by an independent third party — not the abatement contractor and not the property owner.
You can, but the result won’t be defensible. NC DHHS, EPA NESHAP, AHERA, lenders, and insurance carriers all require an accredited inspector and documented chain of custody for the result to be legally usable. The act of dry-scraping a popcorn ceiling can also spike indoor fiber counts into the thousands of fibers per cubic centimeter — contaminating the home you were trying to protect.
Tell us what you’re looking at — popcorn ceiling, vinyl floor, pipe wrap, post-abatement clearance, real-estate timeline — and we’ll scope the right test the first time.
A bulk PLM is the cheapest insurance policy a homeowner or contractor buys before disturbing suspect material. Tell us what you’re seeing and we’ll take it from there.
