I had a bad water issue in my basement and instead of digging up the concrete floor and installing french drains, Humberto addressed the issue of water getting in in the first place. He sealed and refinished our driveway and waterproofed the area where driveway met the foundation of the house. Also installed sump pump in landing of basement stairs and installed drains in the window wells. He was very responsive and wonderful to work with. I highly recommend!

5.0 Nancy S. Ellicott City, MD

I had restoration of brick porches, flagstone sidewalks and a concrete driveway. All of the work was scheduled and completed during a 2 week period. The team was extremely professional and skilled. Humberto thoroughly explained the processes they would use. The company used quality products to do the work. Worksite was left clean every day. I couldn't be more pleased with the results. I have already recommended this company to several neighbors and friends. However, the work speaks for itself. People are stopping by to compliment the job and ask who did it. I am a very happy customer and will use this company again. Nancy Schoenberg Ellicott City, MD June 13, 2020

5.0 Trend F. Clinton, MD

I hired Humberto and company to do some work to my back walk-up; including structure repair, adding a step, burying a pipe for the sump pump and adding some height from the front step plus a railing. Adding waterproofing and concrete surface protection. Humberto carefully explained every suggestion. Always communicated any delay due to weather. He immediately and completely answered questions and concerns. The sub-contractors hired were also professional, punctual, hardworking. Not only on time, but the project was also completed early beyond expectations.

5.0 Wayne C. Silver Spring, MD

3.5 Edward P. Bowie, MD

5.0 Patty P. Bowie, MD

Humberto and his crew were great. Humberto is very professional, polite, and thorough. He kept us posted throughout the project, and he kept his word every step of the way. They believe in quality materials and workmanship. We are very happy with the end result, and I highly recommend Humberto and Quality Waterproofing.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments

  8. Liens Search
