"This company was highly rated on Home Advisor. That is why I hired them. They sent a **junior** plumber to rework the pipes in the shower of a 60-year-old house. I also asked that a new faucet be installed in the lower-level bathroom. In the case of the bathroom repiping, a couple of mistakes were made according to the tile installer who had to ask for a correction. In the case of the lower bathroom faucet, I was told that because of the pedestal sink, a portion of the bathroom wall would have to be replaced. I certainly did not want that to occur to replace a faucet. Ultimately, this inexperienced plumber asked the main office to send another plumber to do the work and determine how to save the wall in the process. Day 2, a more experienced plumber came, changed the faucet without further adieu. The total cost of all of this far exceeded what I expected."

"We would Highly Recommend A & C Plumbing.They did an extraordinary job and really went the extra mile for us. We had to replace our main service line. And they were able to come the day after the estimate to do the work, and get the proper permits, which was great since we didn't have any water. They spent the entire day getting a monster of a job done, in the scorching heat. There was a hand dug trench 3ft deep 6 ft across for the main service line, replaced the ancient galvanized main service line, and a whole new up to code system installed inside. So, they go to tie the house into the city line and there's a leak on the city side too. They called it in to DPW and finish their part, and we had water (we hadn't for over 2 days at that point). A & C gave us the DPW work order number and we all think it's going to get taken care of, right.....ð ¤ For the next 2 weeks DPW says they are investigating and to be patient. Then they tell us it's our fault and the leak is on our side, which we knew wasn't correct, and  contacted A & C. We called DPW, A& C called DPW, we emailed, and A &C emailed. We finally got an inspector to really investigate, then DPW came to fix it, twice, after first visit we had no water. Anthony came to the second DPW service call to talk to the crew, supervisor and inspector, to make sure everything was ok and to see if they had any questions for him, then he went to his other job site. When DPW tied the house back to the water main they had clogged the line (working in an open muddy pit) and told me to call the plumber. I called Anthony (A &C), informed him of everything going on. When he finished the job he was working he came back to the house, he cleared out the traps he just installed we Finally had Water! A & C Plumbing are a small local business that really stuck with us and helped us with a difficult time with the water company. Anthony came back when we really needed him to Personally talk with the DPW work crew, supervisors, and inspectors. Competitive rates, Quality work and a Warranty!"

"Several years back, I called for help and we talked through my problem. We concluded that no water was leaving my house and it was backing up out of a pipe in the basement. In talking through our architecture and location, he determined this was most likely something that could be solved by Baltimore City services (for free). That turned out to be the case. The City workers came out fairly quickly, identified and cleared the clog outside my home, and I paid nothing (outside of my tax returns, of course ... "my tax dollars at work"). Knock You Out could have tried to make some money off of me by saying they needed to come out and look at it, then referring me to the City, and then charging me for their time/truck-roll (while prolonging the entire thing for me). Knock You Out is not cold and unscrupulous. By spending time with me on the phone, but doing no work here and making nothing from it, they proved themselves to be honest and decent people. And that may be the main thing we shop for in home services."

"Robert Boccia, the owner of the company, came to my rescue within about an hour of when I called. A rental property had a complete blockage in the waste line. He rearranged his schedule so they could do the line replacement the next day. His crew began working around 9am. The waste lines for all the other houses in the neighborhood line up with the front bedroom window. That also lined up with where waste water lines were found in the house. The crew worked hard to minimize damage to the tree that my late father had planted and loved. When, after several attempts, the waste line couldn't be found, calls were made to the City offices to determine where the line actually was. While time and effort could have been saved by calling ahead, in most cases, it wouldn't have been necessary because waste lines are typically buried in a predictable fashion. My house proved to be the exception. Finding out where the waste line was actually located turned out to be good news and bad news. Instead of being to the left of the walkway to the house, it was on the right UNDER a concrete parking pad. This significantly changed the scope of the job. Again, the crew found a solution that minimized damage: instead of breaking up the entire parking pad to dig out the old line, they took out the rightmost portion of the pad, which, happily, came away cleanly, and dug a trench to the right of the clogged/collapsed portion of the line. They found the waste line close to the house, attached new pipes and then ran a new line to the right of the old line, essentially doing a bypass. I had previously spoken to another company about my waste line problem, and they didn't know their right hand from their left. I'm so glad I called Glenoak Plumbing to do this job. It needed to be done immediately and correctly. It was."

"upon inspection of the old tank it was determined that the tank itself, bladder, etc, was fine but the couplings at the bottom were corroded resulting in a pin hole leak. Jim offered me the choice to try to replace the couplings and save the tank but pointed out that since the tank was 10 years old it could fail sooner than later and I'd have to go through the labor charge all over again...we both agreed it was best to replace the entire tank and fittings to get it taked care of right the first time. Clearly the best way to go but nevertheless appreciated being given the choice. Jim and his assistant Glenn, were very professional and courteous."

"Was able to inspect the hot water heater and order the parts to install the very next day. Hot water heater now works better then ever. Just wasn't sure about writing the check to the repair man and not the actual company.

FAQs for sewer main install, replace or repair projects in Forest Hill, MD

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
