Expansion & Control Joint Sealants for Commercial Properties
We install and replace exterior joint sealants for condominiums, hotels, multi-family communities, and commercial buildings. From expansion and control joints to window perimeters, facade transitions, and concrete surfaces, we build the scope around the joint, substrate, movement, exposure, and condition of the property.
Joint Sealant Work for Building Exteriors, Openings & Concrete Surfaces
We install and replace expansion and control joint sealants on commercial buildings, condos, HOA-managed properties, hotels, and multi-family communities. Our crews work on parking structures, plaza decks, building facades, window and door perimeters, and concrete surfaces that require properly prepared and sealed joints.
Whether the project involves new sealant installation or replacement of failed material on an aging property, we start with the existing joint conditions. Material selection and joint preparation are matched to the substrate, expected movement, exposure, and project requirements rather than using one sealant system everywhere.
Sealant Systems Across the Exterior Building Envelope
Commercial sealant work often crosses several parts of the property. The right scope depends on where the joint is located, how it is expected to move, what surfaces it connects, and how exposed it is to weather and water.
Expansion Joints
Sealant installation or replacement at joints designed to accommodate movement between building sections or materials.
Control Joints
Joint treatment on concrete, masonry, stucco, panel systems, and other exterior assemblies where movement or cracking is managed through a defined joint.
Window & Door Perimeters
Exterior perimeter sealing around openings where failed sealant can leave gaps between frames and surrounding wall systems.
Facade Transitions
Sealant work where different exterior materials, panels, wall sections, or architectural components meet.
Parking Structures
Joint sealant work on parking decks, garages, ramps, and concrete areas where movement, traffic, and weather exposure affect the assembly.
Plaza Decks & Walkways
Sealant replacement at exposed joints and transitions on pedestrian surfaces and exterior common areas.
Stucco, EIFS & Masonry
Joint and perimeter sealing coordinated with exterior wall systems where flexible transitions are needed between adjacent materials or openings.
Maintenance & Replacement
Removal and replacement of cracked, separated, hardened, loose, or otherwise failed exterior sealant on existing commercial properties.
Preparation Matters as Much as the Sealant Itself
Replacement work starts by getting the joint ready to receive the new material. Clean, sound bonding surfaces and the correct joint configuration are important to how a sealant system performs.
Depending on the joint and specified system, the scope may include failed-material removal, cleaning, substrate repair, primer, backer rod or bond-breaker material, and tooling. We follow the requirements of the selected sealant system and the project conditions rather than treating every joint the same way.
Evaluate the Joint
Review failed material, open gaps, adhesion loss, substrate condition, joint geometry, movement, access, and surrounding surfaces.
Remove & Prepare
Remove failed material where required and prepare the bonding surfaces so the new system is installed against clean, sound substrates.
Set the Joint Configuration
Use the backing, bond-breaker, primer, depth, and other preparation called for by the selected system and the joint design.
Install & Tool
Install the specified sealant with full contact to the intended bonding surfaces and finish the joint according to the system requirements.
Failed Sealants Can Be One Part of a Larger Exterior Repair
Open or deteriorated joints can appear alongside damaged concrete, failed coatings, stucco deterioration, or leaking transitions. When the surrounding building system also needs work, we can coordinate the related restoration instead of treating the sealant as an isolated detail.
For exterior surfaces, decks, balconies, and transitions where moisture protection extends beyond the sealant joint.

Explore Concrete Repair →For failed or deteriorated stucco around control joints, openings, transitions, and exterior wall repairs.
Explore Stucco Repair →For larger property scopes that combine sealants with multiple exterior restoration needs.
