"This is a great company. Artie and Nick were right on time, provided high quality work. They were very professional and saved me thousands of dollars! My home warranty company in house plumbers had told me my main line sewer line had to be replaced (to deny a home repair a camera diagnostic). Replacing the main sewer line would have cost somewhere between $6,500 - $10,000. Artie and I met and reviewed my options. He recommended I go ahead and complete a camera diagnostic and simultaneously have anything in the line descaled. Their descaling machine has a camera attached to it. This process cost $750, but was far less expensive and time consuming than replacing a main sewer line. The end result, verified by camera, a clean sewer line! Thank you so very much BFMD for a job well done! Mary Ann"

"Am starting this review for this contractor as he partially finished the job with the promise to be back in two weeks to address the remaining cosmetic clean-up and seeding.  I will finish reviewing the quality of his work in greater details when he comes back to complete the job started and update on the overall quality of his workmanship. 
Roots from a tree had damaged the sewer line of my 1949 house.  Needless to say, it was not pleasant.  I called five contractors and everyone (with the exception of 1) quoted similar estimates for the job.  I chose Knock Your Plumb Out Plumbing because reading the reviews in Angie's List, talking to a reference, and partially because Johnathan (the owner) was proactive in his communication with me.  He was efficient-visited my house, called the city to get a better idea of my sewer line and the city's, identified that a water line may have to be replaced since the sewer line is beneath it, gave me a quote--all within a span of a few hours.  He then followed-up.  I was initially taken aback on how assertive he was, but in retrospect, it was what made Johnathan stood out amongst the other 4 contractors I called.  Once I screened Johnathan, my husband took over the details in communicating with Jonathan while updating me.  My husband and I were quite concerned initially when we read the negative reviews that Jonathan did not come back to finish the job; however, Jonathan was open and willing to discuss our concerns.  He seemed upfront and a straight shooter, which my husband typically appreciates.
Once the contract was signed, Jonathan called to set up a day to begin the job.  Due to several raining days this past week, the work was delayed by a couple of days.  Jonathan and his crew worked all day to hand-dig the yard and completed the job by the evening.  My husband checked in twice throughout the day.  Our yard looks horrible right now, but Johnathan reassures us that I will look better.  He will come back to complete the job in two weeks and seed the yard for grass.  I will become back to finish up this review.  Thus far though, Johnathan is very professional.  His quote is within the range of other contractors' (although he gives a lifetime warranty-not sure whose life's or how we can enforce that though :))!  He is very communicative and will update you on the progress.  He didn't pick up my phone call but did pick up for my husband on the day he was working.  If all goes well, I will definitely recommend Knock Your Plumb Out Plumbing to other friends in the city and will use him again for other works.  Will be back to update this review.  The rating of B for "overall" and "quality" are not reflective of the work per say but as the work is not completed yet, it will have to be a B right now.

"Mr. Fama had not remembered or written down the appointment time and so came to my house before I got home. Once that was straightened out, he worked very hard to remove my old stubborn faucet and installed my new one. He made sure that it was installed correctly and there were no leaks."

"Don (the owner of Aqua) was in the area at the time I called and was able to stop by within 60-90 minutes of my call. He checked operation of the boiler, and diagnosed the problem with the help of the boiler manufacturer tech support. I needed a new ignition control module; the problem was that the boiler flame would not stay lit. He tried to get the old one working again, and seemed to succeed, but I called him back the next morning to report it started acting up again. He ordered the part and returned after it arrived in a few days to install it. The part appeared to resolve the issue and I was good to go. The boiler is over 25 years old and my previous HVAC contractor had said it needed to be replaced. Don looked at me like I was nuts when I told him that. He genuinely believed in repairing rather than replacing if at all possible, and I could not agree more."

FAQs for sewer main install, replace or repair projects in Hampstead, 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.
