Editorial Review

Our Take on A.M. Shield Waterproofing Corp.

A.M. Shield stands out for credentials that can be checked and for reviewers who describe both the diagnosis and the cleanup in detail. The main trade-off is geography, since the base is in Albertson and Queens is the only borough its site names. Reviewers also mention being steered toward cheaper fixes rather than the biggest job.

What We Like

  • President Hugo D'Esposito and general manager Jonathan Sorscher both hold the CWS credential
  • Operating since 1995 from 33 Albertson Avenue in Nassau County
  • Basement Health Association STAR Award for customer care, eleven consecutive years by the company's count
  • Exterior waterproofing with a 90 mil Tegra-Tite 500 bentonite membrane and footing drain upgrade
  • Named crew members and a semi-annual service check praised in Google reviews

Things to Consider

  • Based in Albertson on Long Island, and the site names only Queens among the five boroughs
  • Google weekday hours (9 to 5) differ from the website (8:30 to 6 plus Saturday morning)
  • Lifetime guarantee is mentioned but the site gives no written terms and no pricing

  • Anthony Levas5.0

    It is with great pleasure that I give my highest recommendation for the water remediation project at my home which was completed yesterday. I am thoroughly impressed by A&M Shield’s professionalism. From initial evaluation by Joe, to diagnosis and remediation design by Jose to the final implementation by the crew under the leadership of Pedro, I am thoroughly impressed with their process and ultimately the outcome of the work. Exterior installation of window wells, property grading and downspout drainage was far better than I ever thought it would be, ensuring water is diverted away from the home. They graded the property and also installed topsoil and grass seed to provide a complete finished look. They performed mold remediation and installation of a Pressure Release/French Drained system with sump pump that ensures a healthy space and that water is removed from below foundation should the water table rise again, like I assume it did this year from the excessive rain we have had. They have put my mind at ease as I think this year’s excessive rain may be the norm. In summary, I am exceptionally pleased with every aspect of A&M Shield’s work and professionalism and grateful I found them and had them performed the work. They get my highest recommendation! Thank you A&M Shield Tony

    Made an appointment online for an estimate. Got an email confirmation with the date and time. Took off of work so I would be present for when they come. An hour goes by and they’re not here. I call and they said that it is just a request, not an actual appointment (even though the email was a confirmation of the appointment?) then they said they have been having issues with the website. Which one is it? Asked to talk to a manager and they said not possible. Asked if they were going to do anything for the inconvenience or for my loss of pay and they said they can’t. Reported them to the better business bureau of NY - someone will be investigating the company further.

Company Background

About A.M. Shield Waterproofing Corp.

Two of the people running A.M. Shield Waterproofing Corp. hold the Certified Waterproofing Specialist credential, and the company's own site says it was the first in the Long Island, New York City and Westchester region to have nationally certified specialists on staff. President Hugo D'Esposito has served on the board of the Basement Health Association, and general manager Jonathan Sorscher joined in 2004. The firm has worked out of 33 Albertson Avenue in Nassau County since 1995 and lists Queens, Nassau, Suffolk and Westchester as its service areas.

Exterior work is the specialty. The crew excavates to the footing, repairs loose concrete, applies a Tegra-Tite 500 bentonite membrane over mastic, and upgrades the footing drain. Inside, the company installs interior French drains, pressure relief systems, battery backup sump pumps and speed drains, and it does crack injection, window well correction, dry wells, leak investigation and egress windows.

Reviewers give a specific picture. One homeowner with a wall that leaked every heavy rain credits Hugo for the estimate and Tony and his crew for two and a half days of work, then reports a dry basement after the next downpour. A customer who has used the firm for years praises Vladimir's semi-annual service check, and a more recent one names Jose and Oliver as clean and attentive. A.M. Shield holds 5.0 from 223 Google reviews, read October 21, 2026.

Some limits are worth knowing. The company is based on Long Island, and its New York City coverage is described on its site mainly as Queens, so ask about travel and scheduling for Brooklyn, Manhattan, the Bronx or Staten Island addresses. Google lists weekday hours of 9 AM to 5 PM while the website shows 8:30 AM to 6 PM and Saturday mornings, so call to confirm. The site states a lifetime guarantee on most services but gives no terms, and it does not publish prices.

It suits owners of houses in Queens and Nassau who want a certified inspection and a written estimate. It suits less well anyone who needs a Manhattan co-op or a very small repair done in a day. Ask for the warranty in writing, what it covers and whether it transfers. New York City requires a Home Improvement Contractor licence from the Department of Consumer and Worker Protection for residential work, so check the contractor on nyc.gov. There is no waterproofing specific state licence.
