"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"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."

"Hired for air duct cleaning but mold was discovered and pointed out to us.  With young children in the house, we wanted to attack this problem right away so we immediately negotiated a price.  The primary contact was a bit difficult to understand due to language differences and I'm not confident we got a good price, but we were very satisfied with the quality of the work.  They were very timely and the full service took an hour or so.  My recommendation is to check for signs for mold before you order any air duct cleaning services.

"Heavy drain cleaning machines were taken down my basement including a little camera. They carefully vacuumed out all the water on the the floor and inserted more than 200ft of drain cleaning cable into the main drain, and in less than 45minutes i was all cleared. Same company  steam-cleaned my carpet in march. I will use them again and again."

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