Review by in Brooklyn, MD
The team dispatched to my home was on time very courteous. Other companies offered long wait times but best buy was ready to do the job the same week of the free estimate. The work looks very professional and not a drop of water since the job was complete.
Response by Best Buy Waterproofing, LLC: Thank you for taking the time to give such a great review! We appreciate that and customer satisfaction is our #1 priority! Thanks again!

I want to thank Best Buy for the wonderful job that they did with waterproofing our basement. We have had nothing but rain since they fixed it, and not a drop of water has made it into our space. We had some miscommunication about one aspect of the job, but the president of the company and one of their associates took care of it and demonstrated that they will stand by their product and service. I will definitely recommend them to others.
Response by Best Buy Waterproofing, LLC: Thank you so much for the great review! Everyone at Best Buy Waterproofing takes pride for what they do and they know that customer satisfaction is the #1 Priority! Thank you again for your time to write the review! We appreciate you!

Would encourage people to obtain a second opinion. They did a terrific job but I think we rushed into making a decision to hire them.

A leak was discovered in my townhome basement during a home inspection for a potential buyer. I was under a serious time crunch to get the leak fixed in order to still make the closing date. James called and came out on a weekend in order to give me an estimate AND he got the job done in less than a week. HIGHLY recommend. James was great. Quick to respond, professional and answered all of our questions.
Response by Best Buy Waterproofing, LLC: We appreciate your kind words every much! Thanks for taking the time out of your day to write this review! We are super glad we exceeded your expectations!

Excellent! Quality work! So polite! Ed explained in detail with pics of what my basement needed and he came back out to see how the work was going. The contractors were knowledgeable and so patient, polite and respectful. You can tell when a company takes pride in their work when their name “Best Buy” is on the materials used. If you need your basement waterproofed then your best bet (buy) is to call the pros at Best Buy Waterproofing.
Response by Best Buy Waterproofing, LLC: Thank you so much Mrs. W.[Consumer name withheld at their request] for the awesome review. We do take pride in what we do and I am so happy you saw that. Best Buy Waterproofing is a very passionate company and everyone who works here is a MIH Graduate. (Make It Happen) We strive for A+++++ reviews as an A review isn't good enough. We have high expectations and we will do everything in our power to make it happen! Thanks again as we appreciate you!

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.
