Len The Plumber Heating & Air, LLC is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"Our first encounter with Len the Plumber for gas boiler repairs went well and lead us to purchase a service contract with them for the 15% discount. However once we needed actual plumbing services and after they provided their "free" HVAC annual inspection it all went downhill rapidly. As others have noted the %15 discount is a concept they don't really honor. We were charged $1100 for less than 30 minutes of work for a repair that only required one cut and a simple joint (We had already removed the drywall and trim for access) and about $30 in parts (which by the way good luck getting an itemized bill from these people). On the HVAC side they broke what was a perfectly functioning 4 yr old AC HVAC and then wanted to charge $1200 to figure out how they broke it plus whatever parts they dreamed up needed replacing. They tried to claim the capacitor was bad. BTW - they brute force discharge the capacitors on units as part of their "maintenance check", something they should never do. We had BGE come out since their info was on the installation tag on the air handler and they diagnosed the issue in less than 30 minutes finding the thermostat had been burned up by mis-handling by the Len tech. They also said they never brutalize the capacitors the ways these guys do unless there is already a suspected issue with it. That's because the capacitor could be damaged by the way they handle it at Len the Plumber. So the "free" annual HVAC check cost me 3 days of discomfort and $250. Len refuses to admit wrong doing and will not reimburse us. They got $5000 in fees from us in less than a year so they don't care if we leave because they know another sucker is just around the corner waiting to be taken. These guys should lose their license given their business practices. Stay away from them at all costs."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"They did a great job. We got 4 quotes; they were neither the cheapest nor the most expensive. Everything was done on schedule, and they did not try to talk us into work we didn't need. Very professional, and they did a good clean-up job. We were initially annoyed that they had not cleanly cut through our tile (which we did not think to request), but we would have ended up pulling up and replacing the cut pieces anyway, so it really doesn't matter. Water problems in our basement have stopped! We are very satisfied."

Drain Pipe Installation questions, answered by experts

How long it takes for a pipe to freeze depends on the outdoor temperature, the level of preventative measures taken, and how long the outdoor temperature stays below freezing. With this in mind, expect most pipes to freeze within six to eight hours. Uninsulated exterior pipes can freeze in under six hours if the temperature is below 20 degrees. It takes at least 12 hours for unprotected pipes to freeze at 32 degrees.

Yes, it’s possible to cap a gas line yourself if you’re no longer using it or are simply going out of town for an extended period of time. It’s essential to follow the steps on properly capping a gas line yourself. If you’re uncomfortable with any of the steps, you may want to bring in a natural gas plumber for added reassurance.

Yes, shower water does go into the septic tank. In fact, all the water you use in your home goes into the septic tank. This includes water from sinks, the dishwasher, the washing machine, and toilets. This water is called greywater. It’s important never to put oil or harsh chemicals down any drain because they could cause a clog in your septic system or even disrupt the natural bacteria needed for wastewater management. 

You’ll only need to replace your sink’s pipes when you start to notice signs of wear like corrosion or leaking. Most pipes last somewhere between 20 and 100 years, depending on the material. Copper and cast iron can last up to 100 years. Galvanized steel and brass generally have a 50-year lifespan. PVC pipes last 25 to 40 years.

Sealant doesn’t need to be applied to the bolts, but it can be a good way to stop an active leak in the moment. However, don’t rely on it as a cure-all; instead, make sure to fix the problem at the source by changing or tightening the bolts. 

If you do use sealant, make sure to spread it thickly and evenly across the bolts and the tank's porcelain.
