Lead paint can be found in almost 75% of all housing built before 1978 and a dangerous mold infestation could exist in any home no matter how old the home is. A professional inspection from ASAP Environmental is the best way to protect yourself before you buy.

"We had a pipe break in our kitchen ceiling and an issue with condo owners that felt “the mold was everywhere”. Christopher was amazingly knowledgeable and explained all of the issues without being an alarmist putting us all at ease and did a thorough inspection. As an architect for 40 years he was the best mold expert that I have met and would highly recommend them."

Veteran owned and operated with over a decade of experience in the demolition and environmental services.

"The 1964 bulkhead I had out back was replaced a year ago, but the wood and insulation underneath (the ceiling of the walkway underground to my basement under the back living room) took in water damage and the area was very musty for years. Tom Morneault of Morneault Environmental was the only guy I could find that would not only treat the wood to remove anything growing on it/get rid of the smell, but his team also removed old wood and insulation and re-insulated for me as part of the deal, which was still hundreds of dollars cheaper than the other companies I talked to, which would only remove the old wood and insulation, they don't put anything back in. Tom's team was here by 8:30 this morning and by 2pm they were done and it looks fantastic and smells crisp and clean. They didn't even stop for breaks or have to make any trips to get supplies, they had them all in the van, including the insulation boards. Very highly recommended if anyone is in the same situation."

FAQs for radon gas abatement projects in Hanover, MA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
