"Steve called me within an hour of my request and was at my house within hours. He guided me through the process, handled all of the permitting process from inception through inspection. He dropped the new tank within an 1/8” pitch. He’s an exceptional machine operator and completed the job during the hottest days of summer. BY FAR Fenn was the most reasonably priced contractor. My yard will be better than ever as soon as the grass grows back… Steve evened out the topsoil and removed all of the surface rocks. Can’t say enough good things about the job and its timeline. "

"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. I’ve been involved in court proceedings since May 2024 to get my money back. I won in small claims court and he still has yet to pay me as of July 2025."

We joined Angie's List in August of 2007 and have earned their Super Service Award every year since 2009 when they started that program. HARP Home Services, LLC is here to take care of all your heating and air conditioning needs. Whether you are looking for a free quote on a new central air conditioning system or are ready to install radiant floor heating or a new boiler for those chilly winter months, we're just a phone call (or e-mail) away. Residential & Commercial.

"We had a furnace installed by Harp on July 8th 2024 after it being diagnosed by their technician as to the reason our ac system was not functioning properly. That’s when our troubles with Harp began. The installation was not done properly, we needed 3 service calls to get the ac to work properly. The installers were sloppy. We cleaned up screws and wire and parts from the old furnace for weeks. When heating season began we noticed that the humidifier installed with the furnace was not operating. We scheduled an appointment to have it repaired and they called the day of the appointment and told us they couldn’t come that day and we had to reschedule, so reluctantly we did. They finally came and repaired it. From what the technician told me it was not wired properly. On January 21st 2025( the coldest night of the year) the furnace stopped working. We called Harp to get someone to come to repair it as we had no heat in below 0º weather I was told the best they could do is to come the next day between 2 and 6 pm. I tried to explain that this was an emergency but to no avail. I called my local oil company and they were at my door within 30 minutes( which I would’ve expected from the company who sold us the furnace) the repaired it quickly and told us that one f the wires on the control panel was not attached properly. It cost me $300. I would NOT recommend Harp to anyone. They are not reliable and do not stand behind their promises of service 24/7. Stay as far away from this company as possible. We are sorry we ever started with them."

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 system installation and replacement projects in New Britain, CT

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
