Details. Details. Details. It’s what we specialize in.

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.
