Tower Sealants

What Tower Sealants does

Tower Sealants is a U.S.-based manufacturer of professional-grade caulks and sealants, founded in 2005 as a division of M-D Building Products (formerly Maclanburg-Duncan). The company produces its full product line at a single facility in Gainesville, Georgia, using proprietary vacuum-filling technology that delivers air-free product from the tube, alongside an in-house adhesion validation methodology (TCBSAT-30) that tests across 30 substrates under UV and weathering conditions. Its portfolio spans the AU-1 commercial construction line (acrylic urethane and STPE hybrid sealants plus a liquid-applied barrier for waterproofing), the Tower Tech² professional painting line, residential sealants, specialty repair products (Category 5 Patch, Mortar & Stucco Repair), and accessories including the Reusable Caulk Tube, which the company claims reduces jobsite waste by 85%.

The company serves professional painters, commercial developers, residential builders, waterproofing specialists, modular construction manufacturers, and window/door installers, with products specified to meet ASTM C-920, ASTM C-834, ASTM E84 Class A, AAMA 714-22/808.3/805.2/803.3/802.3, and Fed Spec TTS-00230C standards. Revenue is generated through one-time product sales across three channels: an authorized distributor and dealer network spanning the U.S. and Canada, a wholesale onboarding program, and direct-to-consumer e-commerce through the company website. The firm is family-owned, privately held, and discloses no subscription, licensing, or recurring revenue components.
