Contractors need sealants that perform under pressure—on every surface, in any condition. From high-moisture interiors to harsh exterior environments, the right silicone sealant ensures lasting results and fewer callbacks. This guide introduces the best silicone sealants for contractors from GE—built for the jobsite, tested for performance.
Key qualities contractors need in sealants
Professional-grade results start with choosing a sealant to meet the demands of tough job site conditions. Contractors need products offering:
- Long-term durability
- Quick readiness
- Broad surface compatibility
- High flexibility for areas prone to movement or temperature shifts
Strong adhesion also ensures reliable bonding to substrates like concrete, tile, glass, and metal. Water resistance, mold protection, and the ability to maintain integrity in extreme temperatures are also must-haves.
Speed matters too—fast curing times allow for efficient workflows and fewer return visits. Products with low odor and easy tooling support indoor applications and tight timelines. The visual finish also plays a role. Smooth, paintable—when needed—or color-matched sealants help deliver a clean, professional appearance.
In short, the best silicone sealants for contractors strike a balance between performance, workability, and reliability. GE’s advanced formulations in the Pro Seal Max series are engineered with these priorities in mind, making them a practical choice across a range of building and remodeling jobs.

GE Pro Seal Max: Kitchen & Bath and Window & Door
GE Pro Seal Max Kitchen & Bath is engineered for demanding wet-area applications where moisture, movement, and mold are constant threats. This sealant offers strong adhesion to nonporous surfaces like tile, porcelain, glass, metal, and laminate—ideal for high-use environments like bathrooms, kitchens, and utility rooms. It provides long-term performance with lifetime mold-free product protection, making it a go-to for contractors working in health-sensitive or high-humidity spaces.
Water-ready in just 30 minutes, Pro Seal Max reduces downtime on jobs where fast turnaround matters. It’s also Class 50 flexible—meaning it can stretch or compress up to 50% of its original joint width—which helps it stay intact around fixtures, trim, and joints subject to expansion and contraction.
The sealant is low odor, easy to apply, and comes in both clear and white finishes to suit a range of installations. Whether you’re sealing a new undermount sink or replacing aging caulk in a commercial bath, this product delivers reliable, professional-grade results built to last in wet zones.
GE Pro Seal Max Window & Door excels in tough exterior applications where flexibility, adhesion, and weatherproofing are critical. This sealant forms a durable, watertight barrier around windows, doors, siding, trim, and other exterior penetrations—making it a go-to product for contractors tackling residential or light commercial work.
It’s similarly rated for Class 50 movement, making it ideal for sealing joints and gaps exposed to seasonal temperature shifts, wind, and UV rays. GE Pro Seal Max Window & Door adheres to wood, vinyl, aluminum, glass, fiber cement, and composite materials—offering versatility across a range of exterior finishes.
Unlike many hybrid or acrylic alternatives, it remains permanently flexible, won’t shrink, and is water-ready in just 30 minutes. Its advanced formula also includes lifetime mold-free product protection, making it a reliable choice for high-humidity or damp climates.
With low-odor varieties in both clear and white, GE Pro Seal Max Window & Door blends well with most common exterior color schemes. For pros who need long-term performance with minimal maintenance, this exceptional sealant for contractors delivers reliable results on the first pass.
100% silicone sealants
GE All Purpose Silicone is a versatile, pro-trusted sealant for contractors designed for general interior and exterior applications. It’s a toolbox must for contractors who need one reliable product to handle a wide variety of sealing tasks—from kitchens and bathrooms to siding, trim, and utility penetrations.
This 100% silicone formula offers permanent weatherproofing and remains flexible after curing, so it won’t shrink, crack, or degrade over time. It adheres well to nonporous materials like metal, glass, ceramic, laminate, and plastic, and also performs reliably on surfaces like vinyl, wood, and composite.
GE All Purpose Silicone is water-ready in 30 minutes and mold-resistant, making it suitable for damp areas or outdoor environments with shifting temperatures. The equally low-odor formula is easy to apply and clean up, and it’s available in both clear and white finishes to match most surfaces.
For specialty applications that require higher stretch and movement capability, consider keeping GE’s Advanced Silicone Kitchen & Bath and Advanced Silicone 2 Window & Door on hand. They are 100% silicone and rated for ±35% joint movement, making them a strong choice for sealing around kitchen and bathroom water fixtures and windows and doors with high moisture exposure.
For day-to-day sealing work that demands consistency, GE All Purpose Silicone is a durable, dependable addition to any contractor’s toolkit. Of course, no contractor’s sealant kit is complete without the tools to apply and remove it. For sealing jobs of all varieties, GE’s Sealant Smoothing Tool and Sealant Remover Tool will keep you ready for what the day demands.
Choosing the right sealant for the job
Contractors know that no two sealing jobs are exactly alike—what works for a kitchen backsplash won’t hold up to outdoor expansion joints or utility penetrations. That’s why pros keep multiple sealant formulas on hand, each tailored to different conditions. For example, GE Pro Seal Max Kitchen & Bath is ideal for sinks, tubs, and shower trim thanks to its mold protection and wet-area durability. Pro Seal Max Window & Door is built for weather exposure and movement, making it the go-to for exterior joints, window framing, and siding connections. For everything else—general interior or exterior applications—GE All Purpose Silicone provides a flexible, weatherproof seal that covers gaps around baseboards, vents, and utility lines.
