Very professional work. Happy with everyone with this job. Looks great!

5.0 Timothy S. Hudson, WI

I had a roof issue two years ago and they did such a great job that when I needed my bathrooms done, I knew I would get only quality work. I was not disappointed. The rooms look so good, my wife cannot stop bragging to everyone that this is in our home. Will never use anyone else. True professionals.

Response from Company:

Thank you so much, Tim! We truly value and are grateful for your wife and yourself as clients and homeowners. I looked at pictures of your bathrooms that Carl had taken and I LOVE your newly remodeled bathrooms! They are gorgeous! Again, Thank you, Tim, from the bottom of our hearts. Penny

5.0 Bev B. New Richmond, WI

They did a fantastic job on our shingles and gutters. Josie was very professional and kept us up to date on everything. We are happy to recommend them.

5.0 Patrick D. Columbus, MN

They went the extra mile. Drove to a home with the colors we were looking for. Even worked off a generator when a storm took our power. New roof, new siding great to work with pros!

5.0 Stillwater, MN

Everything was first rate. Carl was professional, timely and responsive in putting the bid together. He did a great job with some silly city building regulations that they tried to apply but did not fit our situation. The project started and finished on time. The work was first class. The guys doing it were great, taking a lot of care in the workmanship. David

5.0 James S. Lake Elmo, MN

The crew was courteous, knowledgeable and very professional. The quality of the work was outstanding and exceeded expectations. The cost was fair providing true value. I give Krumm my highest endorsement.

5.0 Frederick F. Saint Croix Falls, WI

Great salesman/supervisor. Great installation crew

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.
