Project: Install an Oil Fired Boiler or Radiator Heating System
Jim and Cullen did a great job. They came to remove my old boiler and installed my new boiler in two days just as they said. They cleaned up everything and even installed an extra valve I needed with no questions asked. My wife had a broken ankle and couldn't go downstairs and Jim asked her if she wanted him to bring in my garbage cans. All work was done neatly and everything worked excellently. Best price out of three offers too. Highly recommended.

Review by in Peekskill, NY
This morning I had the pleasure of discovering my hot water heater had failed during my lovely ice cold shower. Shortly after I placed the Home Advisor request, Jim called me and offered a very reasonable quote to replace my water heater and arrived around an hour later. He was very kind, polite and courteous; he did a wonderful job. I would definitely recommend him to family, friends and anyone reading this review.

Project: Install or Replace a Bathtub
I had a leak which I was told would require a tub replacement. Another company I spoke with tried to upsell me to a $3000 job. Jim listened and suggested a less costly, less invasive job and did it promptly and well.

Wasn't a big job and had some difficulty getting a reasonable price from other contractors. Jim provided a reasonable estimate and got the job done. Pleasant to deal with too.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
