The owner is great to work with. Keep you updated on everything. The painter is superb and easy to get along with. They (company) go out of their way to make sure you are happy. You can't beat them, I highly recommend you call and use them.

5.0 Patricia C. Ithaca, NY

This is a great team to work with. James, the owner is friendly and accommodating. He was available throughout the entire project for questions and advice. Cory, the painter, pays attention to details, has expert advice on painting and making sure the accent colors stand out. I would hire them again.

4.5 Joe F. Ithaca, NY

Worked in our small siding job between other commitments as those got delayed by weather and design changes. Good workers. Fast and steady. Especially appreciate that they cleaned up nightly.

It was a small project yet he was willing to take care of it. Jim is a really nice person and I hope to work with him in the future.

The Core of JBK is treating customers good and going the extra yard to make sure they are happy and they get 100%. The best part of my job that I really enjoy is meeting new people!!

A great team. Excellent work. Clean and quiet. Had 3 bathrooms done and laundry room. Perfectionists. Will hire again.

4.5 Kim S. Cortland, NY

Jim was thorough with explaining the project and gave a competitive price. Tom, the carpenter, was meticulous with his work and was here every day at 7:30 and worked through the day. The crew was respectful of us and our property, leaving it clean every night. We love our deck!!!

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)
