Real People, Honest Reviews

I set up an appointment with Tony Koppers to look at an outdoor drainage problem that was leaking into my basement in a DC Capitol Hill Row House. Tony was prompt to the appointment and within 5 seconds of looking at the problem gave me a diagnosis and… told me I could fix it myself.
I can’t speak to the quality of work Tony and his team can do, but I can speak to their integrity. Rather than trying to sell me on a sump pump or some other expensive solution, Tony told me that my issue could be solved by a $20 trip to
Home Depot.

“Absolutely the best service ever.  They kept me on schedule which was a complete turnaround from what I have experienced with everyone else in the business.  I shopped for 3 months obsessing about a contractor to do under my house because this is a huge commitment of funds.   These guys were perfect, creative, polite, clean and on time.  They did much more work than anyone that came out, including all the big guys, even working with another contractor because I asked them to…… I cant say enough good about this company.  They are nothing fancy but absolutely you should use them.  Good. old fashioned hard workers. They left not a speck of dirt anywhere in or around my home.
