We are skilled in all aspects of home improvement and home renovation including interior and exterior painting as well.

"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."

"For those of you looking for an honest, kind, caring person in the world of “hazardous vapors” look no further than this company. Kevin at All Clean Environmental Services took my panicked call on a Saturday and listened in detail about health concerns regarding “moth ball odors” in my family’s rental property. With that he volunteered to come and “check out” the offensive odors. Kevin was very discreet as well as thorough in his handling of visit to “our” home.

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."

"Stuart is professional, thorough, responsive and very knowledgeable. He patiently answered all of our questions throughout the inspection and we left feeling like we had a great understanding of the home we're buying. As for the inspection report itself, I intend to reference it for months and years to come as I prioritize improvements. Stuart was also able to turn the report around quickly to accommodate the timelines of our purchase. I would 100% recommend him to anyone in need of home inspection services."

Radon detection and reduction services FAQs

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.

If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.

Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
