4.5 Boulder, CO

They were prompt and efficient.

N/A James I. Lone Tree, CO

Professional. Courteous. Clean. Timely. Efficient. Knowledgeable. Fair. A pleasure doing business -- from sales through job completion and billing.

3.0 Golden, CO

Concrete slab still looking good 18 months later

5.0 Loveland, CO

they were competent people. They were on time, and did what they said they would do.

5.0 James P. Longmont, CO

The Olshan salesman explained the differences in foundation repair technologies in a clear fashion. I choose Olshan because of their transferable lifetime warranty. The crew that came out to do the work did an excellent job in returning our foundation to level. The landscaping they added to keep water away from the foundation in the future looks great.

5.0 Dean A. Westminster, CO

When the work got done, it was fine. Keeping us informed about what was going on when there was a no show, slacked for communications. The project completely changed when the foundation was looked at. All in all, the work was excellent. Communications between crews and management , not good. Crew were hard working. Got job done much cheaper than original estimated. Would recommend to anyone.

1.0 Englewood, CO

Very poor customer service. Poor workmanship, had to come out numerous times to fix problems. Don't return phone calls.

5.0 Golden, CO

The "Olshan man" told me that the matter with which I was concerned was actuallly not that important and that it would remedy itself as soon as the water table dropped and the foundation had an opportunity to dry out. He was very helpful and professional. So, while I cannot rate the job, I can say that Olshan was honest and competent.

3.0 Robert P. Castle Rock, CO

The work, once it was done, was very good and professional. The scheduling, however, was a royal pain! Granted, part of the problem was weather, starting this project in the fall. However, just getting the local Olshan office to communicate with me was very difficult. In the end though, the project is done and we are happy with our new driveway and walk.

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.
