Flag Waterproofing & Restoration Co. has been proudly restoring buildings for more than three decades. We apply the best restoration and maintenance techniques coupled with the finest materials for each unique job--always staying consistent with the original character of the building. We consider a wide array of factors, including the original construction methods, environmental effects, building age, and all relevant features that make up the building character. Then we approach every project in a custom way to achieve optimum beauty and lasting results.

More than three decades of service, one company. One single commitment: your project

Flag is unlike other restoration firms in the Tri-state area: We employ our craftsmen on a full time basis. We employ full time craftsmen to ensure consistent control and deliver the best end-product in the most cost-effective way. The workers on our jobs are the same workers who have been with us for many years.

Depend on us for quality that endures

Flag’s experience means that you work with the same well-respected and dedicated people who comprise our company from more than 30 years ago. As part of our long term commitment, we continually reinvest in our business, bringing the latest restoration techniques and the most advanced waterproofing and protection materials to your project.

Preserve don’t destroy

Our sensitivity to the historicity of buildings and our passion for restoration and preservation translates to the quality of our work.

With our vast amount of privately-owned scaffolding equipment, including six (6) motorized mast climbers, eight (8) hand-powered mast climbers and over 75 suspended scaffolding rigs, our licensed riggers and certified operators can solve any access problem to insure the work gets done.
