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!

"We’ve used Len the Plumber in the past, and while they’ve been slightly overpriced, they’ve been reliable and effective. But after this week I’ll be taking my plumbing business elsewhere, and I would highly recommend that anyone else do the same. Several times over the past few weeks we’ve had issues with the sink and toilet in one bathroom. A little less than a month ago, a Len the Plumber tech had replaced the toilet in that bathroom (not for the same issue). On Friday I called Len the Plumber to have someone come out and take a look. The woman who answered the phone said she would have the same tech that had installed the toilet come out that afternoon between 2 and 5pm. At 2:41pm someone from Len the Plumber called. She said that unfortunately that tech wasn’t scheduled to work that day and the appointment shouldn’t have been made. She told me he could come out Sunday morning between 8 and 11am. At 8:43 Sunday morning, a woman from Len the Plumber called to say the tech would be out in 30-45 minutes. Eight minutes later she called back to say that no, he doesn’t have a snake, so she’ll have to send someone else later. I told her he wouldn’t need a snake, that it wasn’t clogged right now. She said she’d discuss with the tech and call me back. At 8:58am she called me back and said that it sounded like the P-trap was clogged, and the tech would need a snake. I asked why he didn’t have one with him (since he worked for a company called Len the Plumber) and why he couldn’t just swing by a hardware store and pick one up. She said the techs don’t always have snakes, and sometimes they break and need to be fixed. She said she could send someone else out later in the day. I told her that we wouldn’t be here later, and that we had made plans around the tech coming out this morning (after we had made plans around the tech coming out on Friday). She said she would try to get someone out during the same timeframe, within the next two hours. At 10:36am she called back and said that she could have a different tech come out in 30-60 minutes. I told her no, we had planned to be home based on the 8-11 timeframe that we’d been given, and that wouldn’t work. She said she was sorry, but they had emergencies. I canceled the appointment and will never be using Len the Plumber again. The fact that a plumbing company can schedule a call two days in advance for a technician to come out for a problem with a sink and toilet, and neither the tech nor the dispatcher realizes that the tech doesn’t have a snake with him (and for some reason he can’t just pick one up) speaks volumes about the company’s competency. Add to that the bungling of the initial appointment, and the fact that a Len the Plumber tech told me to my face that he has no way of knowing what model toilet he installed in my house without physically coming out to see it, and this is clearly a poorly-run company with an outdated and/or low-quality field service and dispatch system. There are many competent plumbing companies in the mid-Atlantic area. Len the Plumber is not one of them."

"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."

FAQs for solar panel installation projects in Baltimore, MD

Annual inspections are recommended for residential solar systems, though specific needs vary based on several factors. Newer installations in moderate climates require less frequent professional evaluation, while systems over a decade old or those in harsh environments benefit from more regular attention. Always arrange an inspection following severe weather events that might have damaged components or affected system performance.

Pre-inspection cleaning isn't necessary, as evaluating the current condition of your panels is part of the assessment process. Professional inspectors can effectively examine systems regardless of cleanliness level, as accumulation patterns often provide valuable diagnostic information. However, if panels are completely obscured by heavy debris, bird droppings, or other materials that prevent visual examination of the surface, a basic rinse might be helpful before the scheduled inspection.

A comprehensive solar inspection examines all system components, including panels, wiring, mounting hardware, and inverters. Technicians check for physical damage like cracks or delamination, evaluate electrical connections for corrosion or looseness, and assess overall system performance against expected output levels. The inspection may also verify that safety systems are functioning correctly and that the installation complies with applicable codes and standards.

While traditional manual inspections are effective for most residential systems, specialized inspection methods may provide advantages for certain installations. Factors to consider include system size, roof complexity, accessibility challenges, and safety considerations. For multi-story homes or commercial installations where roof access is difficult or potentially hazardous, alternative inspection approaches offer improved documentation and reduced risk, though potentially at a higher cost.
