"The work done was to clear a tub drain. An old and detached stopper was the real issue. They replaced the piping and did some dry wall work because they had to go thru our kitchen to get to the drain. Weâ re going to keep these guys on service for seasonal clearing of th drains. Thanks so much for the fair price and hard work."

"Adrian responded to our immediate issue right away (clear clogged drain). While on the job, I had him quote several other plumbing jobs I wanted to have done. He provided fair estimates and did a great job getting the work done. One job involved replacing two old valves on the main line coming into the house. For this work we needed to coordinate with the water authority to have the water shut off. Adrian was very accommodating while trying to schedule the shut off. He always returned calls and texts which made coordination easy and did a great job with the plumbing work. Will definitely use him again for any future plumbing needs."

"New refrigerator purchased and in process of removing old unit found that copper water line was crimped badly.  I also wanted the saddle valve at source replaced with a more reliable vale, so I called HL Bowman for estimate on a Thursday.  Quoted price of $40 travel fee and $75 per hour was most reasonable among the high quality providers, and plumber came out on Monday.  He worked thru a slightly challenging installation with ease, with a lot of running up and down to basement.  Had a new valve and coiled copper wire installed in about 90 minutes.  Not cheap but work done at a much higher level of quality than before.

"The job took 1.5 days because I had moved everything to the center of the basement. They had 5+ feet of clearance around the perimeter, with plastic covering hung from floor joists. The dust still managed to cover everything behind the plastic walls. My advice: do a thorough job of sealing the space or be prepared to have a big dust cleanup. Only disappointment was that the drain at the foot of the steps to the bilco doors was positioned directly below the internal door. You cannot install a sill on top of this so when finishing we will now have a dangerous transition. This was never explained. Otherwise, a great crew."

French Drains FAQs, answered by experts

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
