Commercial Masonry Repair and Restoration Services

“Façade restoration” is probably a more fitting term for the broad spectrum of service types that masonry restoration projects encapsulate. Some of the most common services we perform include:


    • Thru-wall flashing above window heads. We’ll remove the masonry façade above the window head to expose the back-up wall. Once exposed, a new waterproofing membrane is installed at the back up wall, and the previously removed masonry is re-installed. 
    • Above/below grade waterproofing. Our experts will excavate any soil or earth to expose the existing foundation waterproofing system, allowing us to make repairs or perform a complete replacement.
    • Masonry/Concrete Coatings. Once the brick, concrete, mortar, precast, and/or sealants are replaced, we’ll install brand new masonry coatings.
    • Masonry/Concrete Repairs. Services in this area include the removal of existing mortar and installation of new mortar (“tuck pointing”), brick or CMU replacement, limestone repair, precast repairs, concrete repairs/replacement (partial and full depth), granite/precast panel repairs/replacement, concrete/precast crack injections.


We also regularly perform expansion joints, control joint, and window/door perimeter caulking replacement and window glazing (metal to glass).
