COMMERCIAL
CAULKING &
SEALANT IN SHERMAN, TX.
Sherman's median commercial building dates to 1980 — 46 years old — while Texas Instruments' $30 billion semiconductor campus is drawing corporate tenants who expect Class A facilities. Aging sealants on Travis Street and the US-82 corridor aren't just a maintenance problem; they're a competitive liability in a market undergoing the largest private investment in Texas history.
What Commercial Caulking & Sealant Replacement Includes
Complete sealant restoration for commercial building envelopes — from historic downtown masonry to new semiconductor campus construction.
Expansion & Control Joint Sealant
Grayson County's clay soils expand and contract with seasonal moisture — transmitting building movement directly to expansion joints. We remove all failed sealant material, prepare joint faces to correct geometry, install appropriate backer rod, and apply commercial-grade polyurethane or silicone matched to each joint's movement profile.
For Sherman's industrial parks — Progress Park (3,300 acres), Midway Industrial Park, and Texoma Technology Park — expansion joint sealing in tilt-wall and precast buildings is a recurring maintenance need that we handle with efficient boom truck access, minimizing production disruption.
Window & Curtain Wall Perimeter Sealant
Sherman has 41 recorded hail events in the past 12 months — each one capable of cracking aged window perimeter caulk and opening gaps that admit water before the next inspection. We remove deteriorated perimeter sealant, clean substrate faces, and apply neutral-cure silicone in a proper two-sided bond with no bridging over the joint void.
Austin College's historic campus buildings and Wilson N. Jones Regional Medical Center's patient-facing facilities require window perimeter sealing that matches architectural standards while delivering genuine moisture protection.
Wet Seal & Dry Glazing Repair
Sherman's older commercial core — buildings dating to the 1950s through 1980s along Travis Street and US-82 — predominantly uses wet-seal storefront systems where original silicone has long since oxidized and cracked. We strip all failed sealant, prepare glass and frame faces to bond-breaking-free condition, and apply new wet seal in the correct configuration.
For Sherman's newer Progress Park industrial buildings with curtain wall assemblies, we assess dry-glazing gasket condition and replace failed components to restore factory-spec compression seals.
Below-Grade & Through-Wall Sealant
Grayson County's clay soils exert lateral hydrostatic pressure on below-grade walls — a primary cause of water infiltration in Sherman's commercial basement and loading dock areas. We use two-component polyurethane and hybrid sealant systems at utility penetrations, pipe sleeves, and below-grade wall transitions to create continuous moisture barriers under sustained hydrostatic load.
Heritage Row Historical District properties along S. Crockett Street require below-grade sealant approaches that don't compromise historic fabric — we work within Whitesboro Preservation Board guidelines when required.

Why Sherman Buildings Need Sealant Service Now
Sherman's commercial building stock has a median year built of 1980, meaning the average property is 46 years old. At that age, original caulks and sealants installed in the 1970s and 1980s have undergone hundreds of thermal cycles, dozens of hail events, and continuous clay soil movement. The failure mode isn't visible until water is already inside the building.
The urgency is compounded by Sherman's economic transformation. Texas Instruments began production at its SM1 semiconductor fabrication facility in late 2025, part of a $30 billion campus that will bring thousands of highly-compensated workers to Grayson County. GlobiTech's $5 billion wafer plant adds to the demand. Commercial property owners who want to compete for the restaurants, professional services, and retail that follows semiconductor investment need buildings that present — and perform — at a higher standard.
Located just 16 miles from our Whitesboro headquarters, Sherman is in our core service area. We've worked on commercial buildings throughout Grayson County and understand both the historic preservation requirements of the downtown district and the fast-track schedules of the industrial parks.

Commercial Caulking & Sealant FAQ
How often should commercial building sealants be replaced?
Commercial sealants typically last 10-15 years, but Sherman's conditions compress that timeline. Grayson County's expansive clay soils cause continuous building movement that fatigues sealant joints, while 41 recorded hail events in the past 12 months create additional mechanical stress. Sherman's median commercial year built of 1980 means most buildings along Travis Street and the US-82 corridor have original or first-generation sealants that are well past service life. We recommend inspection every 3 years for Sherman's pre-2000 building stock.
What are the signs of failed caulking on a commercial building?
Primary indicators include sealant that has separated from one or both joint faces, surface chalking or crazing, efflorescence (white mineral deposits) migrating from joints, water staining below window sills, and deteriorating masonry adjacent to failed joints. Sherman's historic downtown buildings — including structures near the 1907 Paul Brown U.S. Courthouse and Heritage Row — show these signs concentrated at original mortar joints and early window perimeter sealants that have never been replaced.
What types of sealants are used for commercial building envelopes?
The primary commercial sealant families are silicone (superior UV and temperature resistance, ideal for window perimeters and curtain wall), polyurethane (paintable, excellent adhesion to masonry and concrete), polysulfide (traditional wet-seal glazing standard), and one-part polyurethane (for smaller expansion joints). Sherman's building inventory spans from 1900s masonry to current semiconductor campus construction — each substrate and joint type requires a matched sealant chemistry. Historic structures often require flexible, breathable formulations that won't trap moisture behind them.
Can caulking replacement prevent water infiltration in commercial buildings?
Yes — and in Sherman's aging commercial stock, it's often the single most cost-effective intervention available. Buildings along the US-82 corridor and Travis Street have accumulated decades of deferred sealant maintenance. A systematic joint-by-joint replacement program closes the pathways that allow rain, groundwater, and freeze-thaw moisture to migrate into wall assemblies. Texas Instruments' $30 billion semiconductor investment is driving demand for Class A commercial space in Sherman — buildings with unaddressed sealant failures simply won't compete for the corporate tenants that investment brings.
What is the difference between wet seal and dry glazing systems?
Dry glazing relies on pre-formed compression gaskets — typically EPDM or silicone rubber — to seal glass to frame. Wet seal uses field-applied liquid silicone that cures in place against the glass edge. Both degrade over Sherman's temperature extremes: gaskets harden and lose compression in winter cold; wet seals crack and shrink in summer heat exceeding 100°F. Sherman's older commercial buildings, including structures near Austin College's historic campus and downtown Travis Street, predominantly use wet-seal systems that require periodic replacement as the original silicone oxidizes.
