"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

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.
