They were excellent. Worked looks great. Walter and his employees were a pleasure to work with. Showed up on time and did an excellent job cleaning up after work was completed. Would highly recommend them.

5.0 Barbara G. Caldwell, NJ

The entire process was seamless. From the initial meeting to the completion of the project. Very relatable and the quality is top notch. We will use this company again for future projects. North Caldwell, NJ

Seemed very honest and trustwotmrthy

5.0 Lynn P. Sayreville, NJ

I waited until it rained to give my review of my gutter. I really liked Walter, he was very professional and did everything in a timely fashion. I also like that as soon as I contacted Angi I got several calls right away.When I tried to find someone to install a small gutter 29 feet and 8 feet high, no one was interested.

5.0 Rosa M. Staten Island, NY

I chose Walter because of his character and reasonable pricing. He was not pushy, was very patient, answered all my questions, and was honest. He monitored the job, explained any issues with my roof along the way and resolved them. His team works hard and was pleasant as well. Overall, they did a great job, he did everything he said he would do and cared about the work. He also stands by his word and I think that is important ( but I also make sure it is in the contract anyway). They cleaned up very well after too. I would highly recommend him and not look anywhere else. After 4 contractors he was the one I went with (and I am picky).

5.0 Erol B. Maplewood, NJ

Quick quoting and job finished on time. I would use them again.

5.0 Chandani S. Livingston, NJ

I always look for value more than the cost of the project and always review the contractor I plan to work with to avoid any future stress. I can say confiidently that you will not go wrong choosing Walter and his crew. He is honest, courtesies and a true professional roofing contractor. I am also an real estate investor and all my roofing and siding work will go to him.

5.0 Paul J. Morristown, NJ

Very responsive, good clean-up, and knowledgeable. I would use them again.

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.
