DMI/ Accusystems for Water & Radon

Description of Work: Performed radon testing and installed a suction port active soil depressurization radon abatement system in our basement. Essentially drilled a hole in the basement, installed pvc pipe from the hole through the wall outside to a constantly running air pump to additional pvc pipe all the way up the outside of the house to above the roof.

Description of Work: Installed radon remediation system and retested for radon levels

Description of Work: I have an unusual house with half dirt crawl space and half cement floor - difficult for radon remediation. Don, the owner of DMI, recommended an initial installation in the cement floor area which brought radon levels down to 1.1 parts, well under the state standard of 3.9 parts. My own initial radon test, done in Febr. '12, prior to the installation, showed radon at 4 times the acceptable level. Don answered all my questions patiently both before, during & after the installation. Was courteous, prompt, diligent, very professional. The original estimate suggested that a stronger fan might have to be installed; This was actually done as the pipe to the sump was not laid in stone but packed dirt.

Description of Work: We purchased our home in Madison, CT and had a Radon test done as part of the inspection with test results indicating no problem in the home. Five years later, we performed a retest and found very high levels of Radon in the air which indicated that the original test had been tampered with, most likely, or not properly done, least likely. We used a local company to install a sub-slab ventilation fan to remediate the airborne Radon. A full test of the water showed that the Radon levels in the water were also very high. Accu-systems quoted on a system that two other companies also quoted and they were the least expensive with the fastest turn time to install the system. Testing after installation confirmed that the system is performing well and we have been able to discontinue using a secondary systemt to raise the PH of the water because the Radon removal process also neutralizes the water. Accu-systems provided the electrician to power the system and was in-and-out of our house the same day.
