    5.0 Maryellen K. Syosset, NY

    We were very pleased with the work done by Brian and his crew.

    5.0 Mike K. Merrick, NY

    They were very responsive and able to fix the roof before the rain came. Even more importantly, there were no leaks.

    Brian Nela [Alsideconstruction] 10/29/2022 2:42:00 PM Brian Nela and a family member as an assistant arrived a little late due to auto and ferry traffic. No big deal. [Normal for the east end of long island.] THE Work ethic was outstanding: (a) explained all work, (b) answered questions, (c) made sure I knew what was going to be done: including the materials to be used and the quality of the materials to be used. In addition, The work was not JUST a repair, it was the installation of a new flat roof over a two-car garage, which necessitated (1) removing the decking, and placing it on the patio (neatly!); (2) removing the stringers, cleaning all debris that lay beneath the decking, including rotted stringers, with nailing to be removed, and biological debris from leaves, tree seeds, etc, (3) power washing the top of the base roofing that will remain, epoxying all rows of nail holes on the 20x17 roof, laying a base epoxy coat prior to installing the new roofing fabric. In addition, Brian cleaned the chimney from my wood-burning stove, surveyed the roof and the flashing around two chimneys, and found the flashings in need of replacement, those flashing were also repaired. Finally, one section of siding on the second story was replaced with a matching sheet of asphalt shingle. For the future: a new roof for the house is under consideration. ***** Brian Nela [Alsideconstruction] is highly recommended.

    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.
