0.50 Peter R. Mineola, NY

We had a bad experience with GreenStar Renovations and Peter OBrien and had to go to court to obtain a judgment against them. We would not recommend them.

5.0 Richard L. Farmingdale, NY

Hired Greenstar to excavate about 35â  of foundation wall to repair with hydraulic cement and re-tar with a membrane to prevent water from seeping thru our wall in the basement.

5.0 Chaya Z. Northport, NY

Peter and his guys did a great job, very pleased with the end result, pricing was very affordable!!

5.0 Kevin F. Saint James, NY

Pete Oâ Brien is. man of his word. He was competitively priced, did great work and followed through on every promise. Not easy to find contractors like that nowadays. Strongly recommend Greenstar/Pete Oâ Brien !!!!!!

5.0 Justin B. Huntington, NY

Peter is an all-around professional guy. He honest, trustworthy, detail-oriented, and fair. Never once did I feel like I had any doubt in my project as he patiently addressed any concerns I may have had. What started out as a kitchen remodel snowballed into several additional projects such as a bathroom project, new floors, railing, etc. The guys that work with him too are skilled and versatile but also respectful of your home. They were in my house for roughly 2-3 months but not one day did they ever leave a mess. I would hire Peter again for a future project in a heart beat. Overall his work was fantastic and for the price you get a great value. I would surely and highly recommend him.

5.0 Chris E. Huntington, NY

Peter and his team are terrific. Professional, honest and do high quality work. I will be hiring them again for a range on construction work; finishing the basement, mud room etc. Highly recommend.

5.0 Shayna F. Huntington, NY

Peter was a pleasure to work with! He was knowledgeable, trustworthy, courteous and conscientious. He offered an array of choices, provided thoughtful suggestions and did not apply any pressure while we weighed our options. He (and his team) completed the job quickly, skillfully and at a fair priceâ ¦ and offered to return to the project should any issue arise. The newly installed countertops & sink greatly improve the look of our kitchen. We are extremely happy with the finished product and hope to work with Peter again in the near future.

5.0 Stuart E. New Hyde Park, NY

Bathroom came out great! High quality workmanship, clean and tidy and very professional, Peter knows what heâ s doing.

5.0 Michele C. Farmingdale, NY

Peter and his team are incredible. Peter renovated my basement, built me a beautiful closet, closet doors he did himself because the size was custom, put up new walls, flooring, electric. His work is creative, meticulous and he is reasonable, reliable and most of all always helpful and friendly. I continue to hire him and recommend him to everyone I know.

5.0 Matthew S. Coram, NY

Peter and his team are the consummate professionals. Absolutely excellent attention to detail, obviously very experienced in all aspects of construction. Courteous , friendly , FUN and finds a solution to all the little things that come up during all projects in the home. I have passed his info on to many people because he is fair, honest, and really does incredible work ! I will hire him again in a second for my next project after the holidays . It s rare to find a company and an owner whom takes pride in his work and won t stop till everything is right! Very very impressive!

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.
