"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"I have used Roy for three items, the latest being a hot water heater replacement (mine had a super vent, hence the higher cost). I first used Roy for a subpump emergency a few years ago. He came out the same day, actually at night with little notice. He replaced the subpump quickly and professionally. Based on the great service and price fro the subpump we have used Roy for other household repair, such as clogged toliets, clogged kitchen sink etc...I highly recommend Roy and AABCO."

"Glenn was quick to respond. I was lucky that he was available on the day I called him. He called me for heads-up on his way that he could not arrive on time, which was good to me as I could do something else until the rescheduled time. The requested work was a simple one, so that a big plumbing company on Angie’s list didn’t even respond to my request:( It was nice that Glenn took care it."

"We’re very happy to have contacted Junior’s Plumbing! After speaking with Michelle on the phone in the morning, the work was completed to our satisfaction that very afternoon! Joshua Eldridge, the plumbing technician came out and was very professional and knowledgeable. He made sure that when he started, he was going to complete the work that very same day! He paid attention to details and took that extra time to install our new house hydrant correctly. We’ve had disappointments in the past with contractors coming out and not completing on time or performing unsatisfactory work, but Junior’s Plumbing did an excellent job. I wouldn’t hesitate to recommend them for your plumbing needs."

"Tom at DR Restore was great to work with. We had a pipe burst in the unit above causing substantial damage to our condo. He responded immediately and was at our condo that night to work on the mitigation. He explained the process upfront and was with us every step of the way. He has been a valuable resource through the mitigation and repair process and I would highly recommend his services."

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

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
