"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."

"Service Tech Brandon H cae for my yearly inspection of the wall braces and sump pump. Brandon was ever the orofessional as we reviewed my covered services and explained some other options for me to consider for the future. The braces were fine, the in checking the sump pump, we found it needed to be replaced. Brandon thoroughly explained the situation and replaced my sump pump in timely fashion. It was a pleasure meeting and engaging with him. "

"Charles and Kevin were outstanding! We were very impressed by the notifications to allow us to know precisely when they would arrive. They were very clear throughout the process on what was required, what the process itself entailed, the cost, and how much time was estimated for the project. In addition, they were very professional and friendly! We would highly recommend Charles and Kevin!"

"Frank and his team at Kozan did an absolutely incredible job on my house replumb! We had to replace our 1980s polybutylene pipes as they were finally starting to leak, and knew it would be an invasive job. I had 5 companies come out and quote me - Kozan came in the most reasonable, but that wasn't the only reason I went with them. When Frank was here doing his estimate, he was the only guy who really looked at the pipes, and started putting together a plan; having worked construction myself, this is exactly what I would've done. All the others were in and out with a handshake and a couple pics. Regarding the work, they replumbed the house with minor intrusion, and even took care to cut the drywall stud-to-stud to make my patchwork a bit easier. They did everything they could to keep the water running to all the lines not being worked on, and cleaned everything up every day before they left. All-in-all the job was very well done, and Frank was a true professional. Thanks Frank!"

"The technician, Marvin, could not have been more professional, knowledgeable and efficient. The main issue we wished to resolve was changing the shower. Marvin communicated the process involved, project pricing and returned on the second day with necessary parts to complete the job. The entire experience working with him was seamless and was a great way to start 2026!"

FAQs for sump pump or interior foundation drains installation projects in Washington DC, DC

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
