This was by far the best company to handle the job. I received a quote from another Home Advisor contractor and they were extremely overpriced. Dan came into my home over a year ago and gave me a quote that was a fraction of the other companies quote. I decided to do the job 17 months later and it was still the same price as quoted over a year ago. The crew came out on an extremely hot day and did the job, working through lunch to be sure to get the job done before it rained. I would totally recommend this company and all who work there. Dan is very professional and an all around honest guy. I would trust any part of my home to them.

Review by in Nutley, NJ
These guys are very professional and very clean. Their work was excellent and have very reasonable prices. We would only consider them if we ever did any additional work in the basement. Highly recommended.

Review by in Bordentown, NJ
I was impressed from the beginning. The owner Dan listened to what I wanted and offered reasonably priced and attractive options, rather than just barging in trying to sell me some high priced system not suitable to my needs. The two guys who did the work were awesome - all done in one day and it looks great. I couldn t be happier!

Amazing experience from start to finish. The owner made us feel very comfortable from the first contact made to the field visit to the next consultation and then the actual work process was painless and very stress free. Would definitely recommend.

This was a very professional business with good communication and great workers . The manager Dan made a great observation that two other companies did not mention which saved a lot of work and tearing up of my backyard. The price was very fair. A great team.

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.
