"Very well. All done and good as new."

"I purchased a radon kit to asses the need for radon mitigation but I was educated by the business owner himself who was incredibly knowleadeable and helpful. If we do have radon over the next 6 months after seeing what the averages are from winter to summer, this is the company we will gladly hire!"

"It was excellent. I've been working with that company for over 12 years now and I always found them to be exceptional at the work that they do. They were personable very responsive."

"These guys were AWESOME. They arrived within 90 minutes, assessed, estimated, and had equipment already with them to handle our flooding. They moved the furniture, explained how it all worked, came back half way through (it was a 3 day process), moved the fans, and then put it all back when they were done at the end of the 3rd day. If every company worked like this - had staff as professional, friendly, and reassuring as these guys - there'd be no need for a better business bureau! Love them. Don't hesitate to use them!"

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

"Rodney is extremely professional, easy to schedule and highly knowledgeable about lead testing! Have used him many times and will continue moving forward. Highly recommend."

"I own a condominium in DC. The inspector tested my unit with his x-ray equipment. It was determined that no lead was found in my unit and I will never have to have it tested again. The inspector was prompt and very knowledgeable. It gives me great joy knowing that my future tenants will be safe in my unit."

"The service was excellent, as usual. I've used this company once in the past. I especially like Wanda who helps answer the phones for the company, she is very pleasant. Two technician's came out. They had to cut out drywall, and cut a 2x4 to access the crack. They then sealed the crack with two different types of materials. One was Teflon over top of the epoxy they used. They also went a step above and sealed the outside crack for me as well. This company is 10/10."

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

"It was a tale of two companies: The technician (Saeid) was excellent--very knowledgable, thorough, and professional. He diagnosed and fixed the problem superbly. On the other hand, the price for services rendered was exorbitantly high, and they completely missed an appointment scheduled, despite repeated calls from me and assurances that someone would be coming out."
