"He was difficult to work with and unresponsive to inquiries. After collecting a down payment from me, he made no progress on the project for months as verified by town hall, despite his claims that the project was in motion.

We are a full service Excavation and Trucking Company with 30+ years of experience. Specializing in Complete Septic System Installation and Repair. New or Failing System we perform perk and have Design Engineers we work with your particular project. Demolition of any Building and removal of debris. We do not perform septic pump outs.
"Addendum to my last review: When the septic pump failed, we discovered how many corners were cut. Instead of a septic pump, a sump pump (for rainwater) was installed with the 1½ inch pipe joined to a 2 inch pipe to make it look like it was supposed to. There was no coupler on the pipe leading to the distribution box, necessitating cutting the pipe to get the sump pump out. No check valve. Do NOT use this guy."

FAQs for septic tank service projects in Windsor, CT
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
