5.0 Tucson, AZ

Ken and his crew did multiple jobs around my home and did an excellent job doing so. They added teal tile baseboards to my master bath and also to the rest of my bathrooms so they would all match. They installed a built in over, installed all new windows throughout my house also sliding glass doors to the back part of the house. His main purpose was to construct a new master bath but I had a few other tasks to do around the house and he was confident enough to take on these other jobs. The crew did a wonderful job I would definitely recommend to friends and family!

5.0 Jack W. Tucson, AZ

The contractor was easy to work with and addressed any concerns I had quickly and to my satisfaction.

Response from Company:

Another nice 1200 sf garage / shop combo with a 3/4 bath. Vinyl siding & aluminum fascia for a no maintenance exterior. Design, plans & complete construction.

5.0 Richard Y. Tucson, AZ

Ken of KR Building & Design was fantastic. He communicated consistently. He inspected and monitored the work at every level. His crew was very knowledgeable and friendly, not to mention, the great job they did. Never a problem. Professional at every level. Best contractor I have used. I highly recommend this company. In addition, he is a very personable person. Thanks Ken.

5.0 Jonathan Z. Tucson, AZ

Ken remodeled the master bedroom, which included new walls, ductwork, electrical construction. He also finished the work with painting trim, doors, flooring and carpeting work. The job was ~$10k. Ken and his team were very efficient and professional. Workmanship was excellent, with full county permitting, and the crew was conscientious about time and materials. Ken also accommodate a couple of small changes in stride. Ken and his team were very easy to work with.

5.0 Tucson, AZ

My remodel, a small but complex renovation involving demolition, rewiring, masonry, ductwork, and painting, was done under County permit, in record time, neatly and proficiently (with one small exception which I was fortunately able to correct myself), with all construction detritus removed every day. Ken and his capable/experienced/amiable employees basically put on a seven-day remodeling "clinic" wherein a minimally utilized space underwent practically glitchless transformation into a useful workroom. Ken, with his decades of experience, encyclopedic knowledge of building codes, and expert grasp of structural and electrical engineering principles , maintains friendly, patient rapport, answers all questions, and explains and attends punctiliously to details. He moves quickly and meticulously, without seeming to hurry, and always toward an apparent internalized image of the completed work. Tucson is indeed quite fortunate to boast someone of this caliber willing to do small remodels rather than to solely build the gorgeous custom homes, seen on the KR website, which probably net him more funds and fame.

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)
