5.0 Frank F. Brooklyn, NY

I had tried another asbestos testing entity, not from Home Advisor, and they wanted $650 just to show up & have me give them a tile & adhesive sample to be analyzed! I searched on HomeAdvisor & Sentinel was able to beat the price & provide a prompt lab report for less with a reasonable rate. Thanks Sentinel & Home Advisor!

5.0 Andy N. Brooklyn, NY

I hired a different company, recommended by friends, to test our basement for asbestos. They found it (in heating pipe insulation, about 18 linear feet) and gave me a quote of $2400. I started calling around for quotes and Sentinel gave me a price of $1600. Kunle of Sentinel also explained that I needed to hire a third-party air monitor â he sent me the (very confusing) regs describing the need. The original company said there was no monitoring needed because the job was under 25 linear feet. I ended up calling the NYC DEPâ s asbestos unit (718-595-3623 if you ever have questions about asbestos in NYC) who explained that in fact for a job of under 25 linear feet, air monitoring was not required, but they very strongly recommended it. So for $550 I found a third party company to air-monitor. Meaning for $250 less than the first guy quoted, I got the project done with air monitoring instead of without. Kunle was a very nice guy on the phone, not at all a hard-sell, and answered any questions. He and his one-person crew came in and were in and out quickly and cleanly. The air monitor report came back clean. All good.

5.0 Gerard i M. Staten Island, NY

Very good professional experience. I used Sentinel Environmental for the testing of tile flooring in my finished basement following a sewer/ water backup. The test proved positive for asbestos tile but luckily negative for asbestos in the dust. The person who came to my home was very polite, professional and thorough. The examiner showed me his state and city certifications as well as the companyâ s. Turnaround wS very fast and prices were very reasonable. I would recommend this company 5/5.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
