"The inspector was professional and thorough. The report was timely and the company's representative called me to explain the results of the test. I've emailed him to request clarifications and am awaiting his reply. The only negative thing is that after our telephone conversation he transferred me to a 3rd party company who markets mold removal services. The rep there tried to sell me his product. I didn't buy it yet."

"We had mold in one room of our new house. As Brandon and his crew pulled out the moldy boards and checked the other boards we realized that the entire extension was not sealed properly. They fixed it for us, helped us find a plumber when a pipe in the room busted(it was a very old laundry room) and were just super nice guys. 12/10 we would definitely hire again!!!!"

"This company is fantastic. We found them on Angie's List and everything we read was true. Our 2 year old daughter is highly allergic to everything and we wanted to rule out mold. John wouldn't do more than was necessary and explained everything you've ever wanted to know about mold in detail. He also talked me through the report so I could share the findings with our allergist. I was really nervous about how much it all would cost, but luckily nothing was found."

"I called Synergy based on Angie's list reviews for removal of popcorn ceiling as it had asbestos. Yes, I had it tested and the results showed it had asbestos and needs an abatement company to remove it. I had an estimate from another company that was referred by our contractor. I thought that quote was outrageous and wanted another opinion. Synergy sent their estimator(Robert) in couple of days. I got the quote the same day evening and it was very reasonable. So I decided to go with the offer and scheduled the work. I had to postpone the work by a week due to delay in moving but they were very nice and worked with me to schedule the very next week as other remodel work was starting right after, On the day of the work, Joe (foreman) + another worker showed up on time and completed all the work in three days (as per the estimate). Since we had moved out of the house for remodeling, we had no issues with existing fixtures or furnitures being at the house. So I did not have to deal with any breakages or incorrect handling. The abatement work itself proceeded with no surprises and they had removed the ceiling fixtures as they said they would, and left the last layer of plastic sheets covering for the walls and floor for painting(as they said they would). So nothing unexpected. They were thorough to set proper expectation and met them. I just completed the abatement last Friday and am expecting the final docs to be shipped to me. Since I paid after the work was complete, I am just waiting for the air sample results, permit docs, final paperwork etc from them. I would recommend them strongly. I hate to leave a review saying how much it cost as every job is different. I did the abatement with the permit and the quote was almost half of the another company. But don't use that as a benchmark, but it was in my case. I am only highlighting that part to show they are priced reasonably. I am glad I called them."

FAQs for mold & toxic material test projects in Brentwood, CA

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
