"I had a great experience with Joe , getting a co-op unit inspected. His price was very reasonable and he was very accommodating when unexpected obstacles occurred on the day of the inspection. He was very thorough and knowledgeable. I love that he explained everything at the inspection, which was very helpful. Everything was also written out in a detailed report that he sent very promptly. We ended up not purchasing the unit. What really helped us with this difficult decision is Joe's leveled and unbiased relaying of what he found at the inspection. He didn't exaggerate any flaws for example. At the end of the day we feel like we dodged a bullet after the inspection and will definitely be hiring Joe again once we find a home to purchase. Highly recommend him."

"Olivier was terrific. He was incredibly thorough and left no detail out of his inspection or his report. He took the time necessary to inspect all elements of the inside and outside of the home, he was patient in explaining what he found, and he was able to put all his comments within a helpful perspective. I would recommend him 100% and would use him again without hesitation."

"Paul cam to assess the mold on my basement walls and he didn't just come in a look. He went above what we thought he'd do and inspect the baseboard in the entire basement. He also checked oitsode to see where the moisture could be coming in from. He was very efficient and helpful with providing information on air filters, remediation, and potential causes and how to prevent. We would use him again."
Ground water infiltration occurred through the concrete slab in two rooms on the ground floor of the house causing water damage and mold growth on the overlying flooring. The cause of the water infiltration appears to be associated with cracks and a crater in the concrete slab, which is believed to have been caused by pile driving work being performed during the construction of an adjacent building.
Mold in HVAC Coil Compartment
Construction/demolition work in an  apartment unavoidably released high levels of dust that migrated into adjacent apartments. Dust containment methods, such as negative air filtration and poly sheeting, should have been used to prevent dust migration into adjoining spaces. Settled dust samples were collected from a table & curtain rod in a nearby apt, which revealed the presence of substantially elevated levels of silica and asbestos in the dust. Asbestos and silica are known carcinogens.

"John M. was courteous, timely, and professional in his inspection. He was upfront about the issues -- whether they are serious or minor, rare or common, and whether more specialized input is required. His written report was very well done and will serve as a great home guide for us in the future after we move in. Thank you!"

Radon Detection and Reduction FAQs, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.
