Review by in Ashburn, VA
Ernest Waterproofing did a very thorough professional job from the moment they walked in our door to estimate what needed to be done through the conclusion of the actual work. On the day the work was to be done, they laid plastic sheets from the door to the work area, and kept me appraised of the work they were doing. I very highly recommend them. They did a 5 star job in every aspect of their work and customer service.

Review by in Warrenton, VA
The quality of the work was excellent. They arrived promptly and finished as promised. They maintained a neat work-site and removed all work related materials when they finished. Plus, they were nice people to work with.

Review by in Sterling, VA
Ernesto and Alex went above and beyond to get to the house, assess the situation and come up with a solution, quickly. The work was done in a single day as promised and, now that we’ve had several hard rains since the fix, I can say confidently that their work has resolved the problem. Also, the best price among several estimates. Would recommend.

Review by in Woodbridge, VA
They worked quickly and efficiently. I ended up paying more than I expected. I won't really be able to assess their work until we get some heavy rain but as of now I believe they did a good job.

Review by in Gainesville, VA
A little unorganized setting up the work. after a couple of weeks was able to set up a time for the repair. The work was done professionally and satisfactorily. cleaned up the debris and dust. No more leaking since. Happy and would use again if needed.

Review by in Great Falls, VA
Competent workmanship - I got basement leak repaired to secure their “lifetime warranty” - ie went with maximum repair recommended. Some scheduling missteps and communication snafus between the estimator and the repair team that led them to back away from quoted pricing led me to take a star or two off. Work quality seemed very good though.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  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.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  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
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
