Review by in Maple Valley, WA
They came a did a majority of the work two days after flooding in our crawlspace. Our old sump pump died, so they brought out a pump a day before their job to pump the water out. I am so glad they did this, because had they not done the work when they did, we would have had major flooding the following week when it rained about 5" in 2-1/2 days. The finishing work was done 4 months later, well after things had thoroughly dried (my only beef is that it took 4 months before they finally finished the work, although this was minor compared to the excellent job of finishing the majority of the work as scheduled).
Response by PermaDry Waterproofing & Drainage: If the crawl space is quite wet at the completion of the system installation, we will leave the vapor brrier off for a time until the surface starts to dry, and then we cover it. Crawl space soil can take 5, 6 even 10 months to firm up and start drying. It costs more to make a return trip to a site just to install a vapor barrier, but it makes for a better finished job for the homeowner.

They gave us options as to what needed to be done with clear pricing. And they showed up when they said they would and finished the job in one day!

Review by in Everett, WA
Came by 1/2 hr late. Nice guy. Let me know of a few things I could try and if I needed further help they would be here for me. Could do better in keeping in contact with customer prior to and post assessment.
Response by PermaDry Waterproofing & Drainage: We appreciate the comments and always take them as corrective criticism. Moving men and equipment on the freeways does not always go as planned. Next time we will do a better job of calling ahead. Management.

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.
