Best Foundation Leak Repair in Washington DC

Received four quotes for three major home projects: A complete master bathroom remodel, a new deck, and replacement of a drop ceiling with sheetrock and repair of a water-damaged wall in a guest bedroom.
The first three quotes were from high end remodelers. A friend recommended Allen Geoffrey's Handyman Services to us (she had just had her bathroom remodeled). Geoff and his crew (Mark and Brian) came out to survey the jobs. They spent more time with me going over what work we wanted and what our major concerns were. They suggested a comprehensive plan of attack from top to bottom. We were consulted at every step of each of the projects to ensure that our expectations and design elements were incorporated.
Their price quote came in thousands (yes, thousands) of dollars less than the three previous quotes. While they don't provide the design assistance of the high end contractors, they met us at a big box contractor store and helped us color-coordinate our design interests. They took care of ordering all the various pieces parts needed and got us a significant discount on materials.
First, they replaced the deck to install flashing (that the previous home owner neglected to do), that led to the water damage in the guest bedroom. The deck was brought up to code and revealed serious problems with the previous deck installation.
After the deck was done, the crew split off into two teams, one working on the master bathroom, the other, working on the guest bedroom.
The crew took care of hauling off all old materials and cleaned up after each day. The work was first-rate.
As with any major home project, unexpected/unforeseen problems arise. While removing the water-damaged sheetrock in the guest bedroom, major water damage was discovered to the exterior wall. Geoff gave me a very reasonable labor estimate to repair the wall. That wall is now the strongest in the house.
They show up when expected, every day, until the job is done.  They go beyond what is expected to ensure that the client is happy with the direction the project is headed.
I highly recommend these master plumbers. I guess my highest endorsement is that, when our kitchen cabinets come in, Geoff and his crew will be doing our complete kitchen remodel (again, coming in thousands of dollars less than the high-end contractors). If you need any work done to your home, give them a call. They will not disappoint you.
And, Geoff, Mark, & Brian, our new master bathroom looks and functions beyond our expectations. Thank you!

After: picture was of bathroom being remodeled. Friendly workers, he responded to messages and contacts quickly. Would definitely recommend to family and friends.

Elliott came to my house to install a new water heater today and did a great job! He was able to fit me in the schedule very quickly and showed up promptly as scheduled. His pricing was great and his work was perfect! He brought the new water heater, took the old one, and set everything up great! It is a gas water heater and he took care of moving the gas and connecting everything back as well. His work was very clean and I would certainly recommend him to anyone else looking for a great plumber!

I called around to have someone come out to look at my toilet that was leaking. I was looking at plumbing companies and somehow ended up leaving a message with James and he called back right away. When I realized he was not an actual plumbing company I was hesitant, but decided to give him a shot since his prices were right in line with the other companies AND he was very prompt to call back. Plus, I liked his voice because he seemed honest and sincere, so I decided to give him a try. He was right on time, walked up and introduced himself, shook my hand and went to work. He knew immediately what the problem was, went to get parts, returned right away and fixed the toilet. He gave me an invoice, thanked me for my business, and shook my hand again. It was such a great experience and when I need other things done, I will give James a call. Thank you!

I've never come across such professional plumbers before. When I was moving in my new apartment the water system had issues. I called these guys and they did a really incredible job. Money well spent with these guys.

Precision completed a large project for us that included building out an in-laws suite in our basement, creating a new laundry room in the primary bedroom and a new closet space.  It was complicated by a leaky sewer which they also were able to replace.  Work ethic and productivity was amazing- the guys did such a great job and made sure everything was done to meet our expectations.  We're so grateful and already planning our next project !

Our realtor recommended Lee to do some work on a home we'd recently purchased. Lee is easy to get in touch with, responsive, and his team did high quality work. He also uses a convenient online invoice and payment system. We would hire Lee again in a heartbeat.

I had the opportunity of using Less Leaks to perform an assessment on my home. Less Leaks is a very professional, thorough, knowledgeable, and punctual business. I was aware of every detail throughout the entire process.

Less Leaks was hired because I had a water bill that tripled from WSSC. I wanted to make sure that my home was not experiencing any hidden internal/external leaks. The entire inspection took about an hour. Less Leaks also winterized my home and pointed out things that may cause issues in the future. Less Leaks also provided paperwork to submit to WSSC, as well as what the issue is.

I highly recommend Less Leaks for anything concerning to increased water bills and leaks.

Horrible service and borderline predatory pricing. Magnolia does not honor appointments, will attempt to upsell you services in excess of 3x market rates, and are generally rude and unpleasant to deal with.

We scheduled a repair with Magnolia for a Tuesday from 10-12, they did not show up. At 4pm, they notified us the tech would not make it that day. The next day the tech arrived, informed us he did not know how to fix our unit, and could not find a leak. He refilled the freon and the system broke three days later. We scheduled a follow-up appointment for 12-2, the tech did not arrive until 3:30. He found the leak the other tech had missed and informed us it would $3,600 to fix or $12,000 to replace (and he strongly suggested replacing because the unit is old).

A simple call to another repair service determined that our unit was under warranty and would only cost time and materials to repair. They said under no circumstances could a replacement unit cost $12,000. We do not typically write Yelp reviews, but want to warn others of this fraudulent business.
