COMMERCIAL
CAULKING & SEALANT
IN HOWE, TX.
Howe's US-75 Business Route commercial strip averages over 40 years old — and constant ground vibration from the Union Pacific rail corridor accelerates sealant degradation faster than most property owners expect. When deferred maintenance has stretched repair cycles, failed joint sealant is the first thing causing interior damage.
What Commercial Caulking & Sealant Replacement Includes
Comprehensive joint sealant restoration for commercial building envelopes — from expansion joints to glazing perimeters.
Expansion & Control Joint Sealant
Expansion and control joints are designed to accommodate building movement — but only when the sealant bridging them remains flexible and bonded. On Howe's aging commercial masonry buildings, Grayson County's expansive clay soils and Union Pacific rail vibration cause continuous facade movement that depletes sealant service life.
We remove failed sealant, install a proper backer rod for two-point adhesion, and apply commercial polyurethane or silicone sealant sized to the joint's movement range — not a generic tube of caulk.
Window & Curtain Wall Perimeter Sealant
The perimeter joint between a window frame and the surrounding wall is among the most failure-prone locations on any commercial building. UV exposure oxidizes sealant surfaces; thermal cycling pulls bonds free; and water infiltrating this joint travels behind wall cladding before appearing on interior surfaces.
We use silicone sealants rated for glazing perimeter applications on Howe's commercial storefronts and window walls, properly primed to the substrate for long-term adhesion.
Wet Seal & Dry Glazing Repair
Older commercial buildings in Howe's US-75 strip rely on wet seal glazing systems — field-applied silicone between glass and frame. These sealants oxidize, shrink, and lose adhesion over time, allowing wind-driven rain to enter the building at every window opening.
Dry glazing gasket systems develop their own failure modes as rubber hardens and shrinks with age. We assess which system your building uses, remove failed material, and restore weather-tight performance to the original specification.
Below-Grade & Through-Wall Sealant
Foundation wall penetrations, utility entries, and through-wall joints are subject to hydrostatic pressure that surface-applied sealants cannot reliably resist. Grayson County's clay soils hold moisture against foundation walls for extended periods after rainfall, making proper below-grade sealant chemistry critical.
We use polysulfide and specialized hydraulic sealant systems for below-grade applications, properly prepped and applied under the conditions required for long-term performance.

Why Howe Buildings Need Sealant Replacement Now
Howe's commercial strip along the US-75 Business Route has a median year built of 1983, meaning most structures are now past 40 years old. Original sealant systems installed during construction have long exceeded their designed service life — and the combination of Grayson County's expansive clay soils and persistent ground vibration from the Union Pacific rail corridor through town accelerates degradation beyond what age alone would cause.
Howe grew 37% in one decade — from 2,600 residents in 2010 to 3,571 in 2020 — as spillover from the Sherman-Denison metro pushed workforce southward on US-75. Businesses along the corridor now face increased scrutiny from a larger customer base. The Texas Instruments semiconductor campus 12 miles north on US-75 represents a $30+ billion investment that continues to drive commercial activity through Howe's US-75 frontage strip.
Based in Whitesboro, Griffin Restoration serves the southern Grayson County corridor — including Howe, Gunter, and Sherman — as part of our core service territory. We understand the specific conditions that affect commercial envelopes in this area.

Commercial Caulking & Sealant FAQ
How often should commercial building sealants be replaced?
Most commercial-grade sealants carry a designed service life of 10-20 years depending on product type, substrate movement, and UV exposure. On Howe's US-75 Business Route, where buildings average over 40 years old and ground vibration from the Union Pacific rail corridor is constant, sealants often fail ahead of schedule. We recommend a professional inspection every 5-7 years, or immediately after any severe hail or wind event.
What are the signs of failed caulking on a commercial building?
Visible cracking, shrinkage gaps, adhesion loss at the substrate bond line, discoloration, and chalky or brittle texture are all indicators of sealant failure. On masonry buildings along Howe's US-75 corridor, look for water staining below joints, efflorescence on brick faces, and interior moisture at window frames. Grayson County's expansive clay soils cause ongoing facade movement that can pull sealants free even when the material itself is relatively young.
What types of sealants are used for commercial building envelopes?
The three primary commercial sealant chemistries are silicone (best UV and temperature resistance, ideal for glazing perimeters), polyurethane (excellent adhesion to masonry and concrete, good for expansion joints), and polysulfide (chemical resistance, common in below-grade applications). We match the sealant type to the joint location, movement characteristics, and substrate — a critical step often skipped by general contractors that leads to premature failure.
Can caulking replacement prevent water infiltration in commercial buildings?
Yes — failed sealant joints are the most common entry point for water infiltration in commercial buildings. On Howe's commercial stock, where deferred maintenance has been common due to constrained ownership budgets, a systematic sealant replacement program addresses the root cause of most moisture complaints. Replacing deteriorated caulking is consistently the highest-value-per-dollar repair available on aging commercial envelopes.
What is the difference between wet seal and dry glazing systems?
Wet seal systems use a field-applied silicone or polyurethane sealant as the primary weather seal between glass and frame — common on older commercial storefronts and window walls. Dry glazing systems use pre-formed compression gaskets instead of field-applied sealant. Both systems fail over time: wet seal sealants oxidize and lose adhesion; dry glazing gaskets harden and shrink. We assess which system your building uses and restore it to original performance specifications.
