Our team has over 90 years of combined experience providing reliable radon mitigation, water filtration, and well pump services and solutions to the Fairfield, New Haven, Hartford and Litchfield Counties of CT. Want to create a healthier and safer home environment? Call CT Radon and Well Water Solutions to schedule a no-cost radon mitigation or well water treatment estimate. We also offer cost effective well pump repairs throughout Fairfield, New Haven, Litchfield, and portions of Hartford and Middlesex counties. Schedule yours today!

"I would not recommend. I am a real estate agent and contracted this company to install a radon mitigation system in a home prior to closing based on a high radon level test during inspection. I met the company rep at the property and he quoted a system later that day after inspecting the home. The system was installed two weeks later and a retest came back more than double the level of the initial test. This company claims they have a warranty to cover any system modification to get the levels below 2.0. The company sent a crew back out twice and yesterday said the slab is too thick for the system they installed, the hole the installers drilled is too narrow and the home is in a flood zone. We knew the home was in a flood zone, but this company never asked about that and did not do any due diligence prior to installation. They are refusing to honor their warranty and are now quoting a different system that is much more costly. Can?t recommend."

Septic Tanks questions, answered by experts

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

The cost of sump pump installation varies depending on factors like the type of sump pump, labor rates, and the complexity of the installation. On average, you can expect to pay around $1,200 for a standard sump pump install. However, the cost may be higher if additional features like a backup system or extensive drainage work are required.
