"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

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."

Grady Consulting LLC is a family owned and operated professional Civil Engineering Company serving Massachusetts since 1998.

"I was looking for a surveyor to do some work on our property. As a long time member I've used Angie's list in the past, but haven't had occasion to do so in quite some time. I looked at the companies that were available in our area and considered Grady Consulting. I was somewhat surprised to see that they only had one, brief review. I made the decision to call after viewing their web site. I first spoke with Marianne at Grady Consulting in late June. I mentioned to her that I had found them on Angie's list and was somewhat concerned that they only had one review. She told me that they were not an Angie's list member. Since everyone I had hired was a member, I appreciated that she informed me that they were not. Since we have never had a survey done of our property, I was unfamiliar with how things worked but told her that we wanted to have our property surveyed and the lines staked. We also wanted a plan showing the elevations and location of the house on our lot. I also mentioned that we wanted this information so that we could have an architect draw up plans for a possible, future addition. Marianne was my first contact and thus my first impression of the company came from her. I found her to be a good listener and very knowledgeable. She both asked and answered my questions and responded to all my concerns. She also asked me about my future plans. She was able to pull up our lot on her computer and to let me know that our property had some wetlands in one corner and said that they would also be able to have their botanist walk the property and mark any necessary areas of concern. She repeated back all that I told her I would like to have done and said she would work up a proposal for us. Then, after reviewing the proposal we could decide on what and how much we wanted to do at this time. After speaking with her, I felt that they were very professional in their approach and was comfortable in taking the next step. We received an email that showed our property on a map and were able to see the small area of wetlands that were mentioned. Also, a very comprehensive proposal that listed the scope of services, the estimated fee schedule, the payment schedule and a rate schedule. Out of the 13 listed services we decided to do the first 4. We decided to wait until the late fall, when they would be less busy, to have the work done. In mid November I called and gave the required retainer and said I would bring the signed proposal to their office because I wanted to show them some old plans we had showing a few changes that had been made over the years to bordering properties. I met with Mr Grady who was very polite and professional. He listened to my concerns, answered my questions and then made copies of the old plans. The next day the botanist came and flagged the wetland areas. He spoke with my husband who told me that he was very knowledgable and personable. Two days later two men came and spent a few hours working and then marked the corners of the property with stakes. The rest of the work on the property took place after the Holidays. My husband did have occasion to speak with the surveyor and mentioned that he was very professional and quite jovial considering the extreme, cold weather on that day. We received the progress invoice for the completed work and it was structured so that you could easily see what was done, who did it, how much time it took, what the rate was and how much we were billed for each service provided. The estimated fee given for this job was somewhat higher than the end cost. An envelope containing two copies of the existing conditions plan arrived a week or so later. Since we received a list of 13 services and decided only to do 4, we now have the information for future work we might decide to do."

FAQs for septic system installation and replacement projects in Leominster, MA

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.
