How We Got Started

I chose to work in this industry because John Lombardi formed John’s Waterproofing Company in 1974 in Washington. In 1975, John became licensed, bonded and insured in Oregon. Since then John’s Waterproofing Company has been educating the public about water issues that occur under our homes and businesses, and helping our customers solve those water intrusion issues. We enjoy creating healthier homes for our customers at a great price. .

We started in this industry in 1974.

We describe our business as Well established

There was some miscommunication between the dispatcher and I but the plumber that came to my house explained the issue and rescheduled me for the weekend. I explained the urgency of filling in the trenches and he accommodated my schedule, he was great to work with. He spoke very highly of his company, not something you hear everyday from employees!

From beginning to end of the job,everything went pretty much as planned. The Work Crew , lead by the Foreman, Lupe were great , thorough and swift in their work. They left my basement the way that they found it and so far the equipment that they installed seems to be working well.

Review by in Lake Oswego, OR
We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that 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)
