    Kept us informed as work progressed.

    5.0 Jared P. Kirkland, WA

    Water started collecting in my basement after large rain showers this fall and it turned out that I had a crack in my foundation wall. Called Injectech and they were out the next day and had the crack all sealed up. It's been nearly two months now and my basement has been bone dry since. Crew was professional, courteous, on time and got the job done. Would definitely use again.

    Great overall experience. Excellent customer service and subject matter expertise.

    There was dampness on my basement. The building was built in 1940ies, and I thought there was a crack in the foundation. I talked to many companies, and some of them even suggested to have straining wall replaced along with the building. They supposedly think in this way underground water will flow away from the building. It did not make sense for me since none of the house has the wall around them to protect from the underground water. Morgan contacted me in an hour after I filled out the form on Home Advisor and with no time came and checked, and solved the problem. He and David covered the floor with resin -like material. He is very professional and very quick. Because of him without any delay, I completed my renovation.

    5.0 Linda W. Edmonds, WA

    WOW! Great customer service!! We had a small leak in our basement and could not fine the problem. We had three other contractors (not listed on Home Advisor) over and all they could talk about was to dig up next to the foundation for $15000.00 or more. Morgan looked at the wall, found a crack that NO one saw and within two days had it fixed for a third of the price we were give by others. Morgan and his crew are very professional, cleaned up the basement when they were done. We would highly recommend them for any job.

    5.0 Steve M. Kirkland, WA

    Highest rating for this company and it's president/owner, Morgan Mullin. He contacted me very quickly and arrived promptly to our mutually agreed appointment. His was the only company to come out and give us an estimate. Morgan and his crew arrived when the promised and completed the work completely. After the large volume of rain we have had recently, our basement is still dry. We are very impressed!

    4.5 Janet H. Kenmore, WA

    We just had a small water seepage below the stair well, on the basement floor. They did the job in the time that Morgan said it would take, and the seepage is fixed. Very friendly guys. They cleaned up everything when they were finished. I would recommend them .

    5.0 Philip S. Seattle, WA

    Morgan and his assistant Jordan were both knowledgeable. They worked smartly and were efficient. The work was high quality, the basement and yard were cleaned thoroughly when they were done. Morgan came up with creative solutions for our leakage problem. They addressed all our areas of concern. I am confident that they have cured our leakage issues. And if there is any leakage, Morgan will follow up. I would hire them again and would recommend them highly.

    Very good people and great to work with.

    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.

      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.

      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.
