Joint Sealant Replacement

Remove failed sealant from control, construction, and expansion joints and install new sealant for a watertight envelope.

Joint sealant replacement removes aged, cracked, or debonded sealant from control, construction, and expansion joints and installs new sealant to maintain a watertight envelope.

02

Applicable across all structure types when sealant fails through adhesive or cohesive cracking — referenced to ASTM C920.

03

We saw or grind out failed material, clean joint faces, install backer rod where required, and tool new sealant for proper geometry and adhesion.

04

Fresh sealant is low-cost insurance against water entry at joints — one of the most common paths for chloride and moisture into Florida concrete.

01

How often should joint sealant be replaced?

UV, traffic, and movement shorten life. Many joints need renewal every 5–15 years; inspect annually for cracks and adhesion loss.

02

Can new sealant be applied over old sealant?

No. Failed sealant must be fully removed so new material bonds to clean joint faces.

03

What sealant types do you use?

Polyurethane, silicone, and other ASTM C920-compliant sealants selected for joint movement, substrate, and exposure.

04

Is this the same as expansion joint replacement?

Sealant replacement addresses the flexible seal. Expansion joint systems may also include glands and headers that need broader repair.
