"My husband and I used David in the spring for the home inspection on a property we ended up purchasing. He was easy to get ahold of, available quickly, and incredibly knowledgeable. We purchased an almost 4000 square foot, 135 year old home, and David went out of his way to check every square inch of that property. He arrived early and had already checked the exterior by the time we got there to join him. He was excellent to deal with, made the process painless, and had some great advice for my husband and I as new homeowners. The follow up email with his report was detailed and included photos of every part of the house. His pricing was also very reasonable, especially considering the size of the home. Highly recommend!"

"Peter and his crew were great. Peter was prompt in responding to my inquiry and came out to the house to walk through the lead report and work that needed to be done with me. He gave me a number of options for remediating things and showed me where we could do things in a less expensive manner--explaining the costs and benefits of the different approaches. For example, in one area he told me it was going to cost a significant amount for him to remediate and that it would ultimately be much cheaper for me to replace a section of wood railing instead of remediating the paint. This was to my benefit and his detriment, so I really appreciated it. His crew remediated 15 historic windows and they fixed some cracked panes of glass without my even asking. Peter was very fair, always in communication, and they completed the work promptly and professionally. I highly recommend."

FAQs for radon gas abatement projects in North Chelmsford, 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.
