"Matt, AJ, Scott, Vinnie, Charlie all did a terrific job. They installed a gas water heater, installed a shut off on the water heater where there was one missing, replaced a kitchen sink from an old double sink to a new full size sink and in doing so, moved the garbage disposal and re-piped the whole project. They checked other pipes & plumbing and repaired a broken outside water pipe. Tisha in the office was also wonderful - very accommodating, congenial and they are all very customer service oriented. Respectful, honest, and I would highly recommend this company to anyone."

"Jason was prompt and helpful and was very flexible in changing or modifying the nature of some of the work before starting. He did virtually all the grading himself and knew exactly what to do. The work was done on time and as specified. I will surely contact him if I need drainage work for another project."

"When in need of a new septic system to replace an aging cesspool I contacted several advertised septic companies. Site estimates were from $15,000 to $20,000 for a simple installation to $25,000 - $30,000 with difficulties. So, with the information found on Home Advisor we chose Dan Mackin Jr. Construction from Jewett City, CT (860-376-6591 or 860639-7933) whose estimate after examination of the site was $13,200. It turned out the only acceptable area required extensive ledge removal! Mackin Construction removed the ledge at no extra cost. After installation was complete, the area was totally restored to our satisfaction. At no time was there a lack of communication (verbal or digital) between the customer and the contractor. Payoff was $13, 050 because we were credited $150 for parts not needed. BOTTOM LINE: This is one of the last family owned businesses of this kind that deliver a quality product at a fair price!"

"Paul was very knowledgeable about what needed to be done to replace my whole Septic System. The installation that was completed was amazing and flawless. Paul worked with the town to get the system in and approved. Paul answered every question in a timely matter. I did not have to worry about anything regarding this big project. I recommend Paul 200% and would share his information with all my family and friends. Paul is a master at his work and is priceless in this industry. You will not feel like a number or inconvenience with Paul. Give him a call and let your worries be out to rest with his work."

Septic Tanks questions, answered by experts

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.

Septic tank odors can happen because of a few different issues with your septic system, such as a full tank, clogged drains, or blocked venting systems. Not only is a smelly septic tank pretty unpleasant, but it can also pose a potential hazard to yourself and your home. Toxic fumes could be hanging around, or untreated wastewater could be harming the environment.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Yes, experts handle manual pumping, chemical flushing, and equipment use properly, ensuring thorough cleaning and legal compliance with disposal regulations.
