"Norman is an upstanding business owner with integrity. He's also friendly, knowledgeable, and a clear communicator. He sent all of his credential ahead of time, arrived 5 minutes early, and explained his process and everything he was doing. When there was a minor misunderstanding, he offered a compromise on price just to make sure we were fully satisfied. A real gentleman. I would 100% recommend Norman to anyone in need to lead testing services!"

"Work team was polite, on time every day and highly professional. They explained the process in detail and kept us informed during each phase. I highly recommend D&H."

"We hired Mighty in 2020 for soot removal after a kitchen pot caused smoke to accumulate all over the apartment. Mighty did an excellent job. They arrived promptly to inspect the damage and did a thorough clean up. I highly recommend them."

"Excellent work! Prompt, responsive to emails and phone calls. Justin went out of his way to finish the work on the agreed date. I’m very happy with the work and quality."

"We received an asbestos inspection/test for our old plaster walls and ceiling areas. The turn around times were fantastic - inspector was in our area and able to fit us in the same day I called. Sample results and accompanying lab report were emailed within 36 hours. All samples were analyzed by a local lab accredited under the NIST NVLAP Asbestos Fiber Analysis Lab Accreditation Program, so I felt comfortable trusting the results. The inspector seemed very knowledgeable and helped walk us through any areas that could be of concern. Thankfully all samples were negative, but the modest inspection and sampling fees were well worth the piece of mind during our remodel. In short, I highly recommend this company for asbestos testing/inspections."

"Quick response, well documented process, epa certified. Was very easy to work with, thorough, and helpful to make sure testing was comprehensive."

"Gina Raspa was wonderful to work with.  She responded within 24 hours to my email and she performed the testing within 4 days of my first contact.  Everything went smoothly thanks to her willingness to respond as soon as possible.
The news was much better than we expected and Gina gave me 3 recommendations for companies who could successfully perform the clean-up.
Thanks to Gina, we were able to move the family into the house without fear of future health issues.
I give Gina and her company the highest ratings because she earned them.
