"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

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 repair projects in Concord, NH

Leach field failure can often occur due to a lack of proper maintenance, hydraulic overload, or environmental factors. When too much water enters the septic system—like running multiple large laundry loads back-to-back—it can overwhelm the leach field. Regular professional inspections, ongoing maintenance, and spacing out high-water-use activities help prevent failure.

A septic tank shows repair needs when noticeable symptoms arise around your home. Noticeable signs include strong sewage odors at fixtures, recurring pipe blockages, pooling water or damp patches near the leach field, and areas of unusually bright green or spongy grass. These indicators confirm that deteriorating components or clogs exist. Monitoring such signs and scheduling timely professional inspections prevents further costly damage.

Adhering to a strict, scheduled maintenance plan prevents septic system repairs. An annual inspection and a pump-out every three to five years safeguard your system’s performance. Additionally, only flushing waste and toilet paper, installing drain filters, keeping nonapproved items out of the system, and avoiding excessive water use help maintain your septic system’s health and efficiency.
