"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."

"Excellent technicians. Very professional. Great to work with. Honest and did not try to talk me into additional repairs I do not need right now. Quick working replaced control box, pressure gauge, pump switch, flushed and repressurized the tank and got everything running again."

"I saw a water spot on the ceiling of main floor. I suspect it is from the bathroom of master bedroom, and I removed toilet. Matt found the small crack on the flange of toilet. He give me a price to fix it and also suggest me I can use epoxy to fix it. He check the whole home plumbing, and replace the worn of flapper of two toilets. When he came in, he always wear a shoe cover. The whole process is very smooth and he did a good job.

"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

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.
