Our full service philosophy includes working with each client in creating and maintaining a schedule and providing communication throughout the project, and minimizing any inconvenience to building tenants.

Caulking & Waterproofing

Has your building been affected by weather and age? Leaking roofs, windows frames, joints between concrete panes, decks or balconies? Fix early! Leaks can cause major damage and major construction/restoration needs.

As original building sealants fail from weather and age, the openings left behind can cause hazardous situations, mold, and water damage in the building. This damage can cost thousands of dollars if left unfixed.

HSG Waterproofing Experts repairs sealants by removing failed caulking, priming the surface, and adding new sealant and waterproofing as needed. The quality of our work keeps properties from greater damage down the road by being proactive about caulking and waterproofing.

Our specialists will walk you through the right tests and inspections, and then give you recommendations on how to solve your water damage issues. We can also bring product experts from our manufacturers to your project to support leak source investigation, identification, and material specification.

HSG offers a variety of Waterproofing Service to include but not limited to:

  • Roof Deck Coating
  • Elastomeric Coating
  • Parking Garage Coating
  • Concrete Repairs
  • Grout Injection
  • Wetsealing
  • Planter Coating
  • Epoxy Injections
  • Curtain Wall Inspections

‘There Whenever I Need Any Type Of Work!’

HSG has always been there whenever I needed any type of work, most recently for water proofing. Due to the heavy rains we had a small water leak on the 15th floor, all I had to do was to place a call to HSG and they immediately came up with an action plan. Response times are great and the staff are always professional and courteous
