Treasure Coast Locksmith provides door sweep & weatherstripping services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Door sweeps and weatherstripping seal doors against drafts, water, pests, smoke, and sound. Main products: door bottom sweeps, perimeter frame seals, smoke gaskets for fire doors, and intumescent seals that expand under heat. Pemko and NGP are dominant commercial brands.
Door sweeps and weatherstripping seal the gaps around doors. Gaps allow air, water, dust, insects, rodents, and sound to pass. In fire-rated applications, gaps allow smoke passage that defeats the purpose of fire doors.
Proper sealing matters for energy efficiency, pest control, comfort, and code compliance.
Commercial weatherstripping uses specialized products from manufacturers like Pemko, NGP, and Hager. Door bottom sweeps mount to the bottom of the door meeting the threshold. Perimeter seals mount in the frame around the door.
Smoke gaskets provide silicone sealing for fire-rated doors. Intumescent seals expand when heated to close gaps during fire events.
Treasure Coast Locksmith installs commercial sweeps and weatherstripping for offices, retail, medical facilities, schools, and institutional buildings across Port St. Lucie, Stuart, Vero Beach, Fort Pierce, and every Treasure Coast city.

Weatherstripping types and selection
Commercial weatherstripping products serve different sealing purposes. Understanding the categories helps specify correct products for each application.
Door Bottom Sweeps: Mount to the bottom of the door and seal against the threshold when the door is closed. Available in many materials:
• Brush sweeps - flexible brush material, good for uneven thresholds
• Neoprene blade sweeps - rubber blade seals firmly against smooth thresholds
• Vinyl blade sweeps - economical option for lighter sealing
• Automatic door bottoms - drop down when door closes, retract when open (for ADA threshold clearance)
Brands: Pemko, NGP, Hager, Endura.
Perimeter Seals: Mount in the door frame around the perimeter of the door opening. Seal against the door face when door is closed. Types:
• Silicone bulb seals - compression seal on bulb profile
• Foam-filled vinyl - softer compression with foam core
• Brush seals - flexible for irregular gaps
• Spring bronze - traditional metal seal, extremely durable
Installation in frame kerf (slot) or with adhesive backing.
Smoke Gaskets: Specialized for fire-rated doors. Silicone-based gaskets that seal against smoke passage. Required on many fire-rated assemblies per NFPA 80.
Must be UL-listed for the specific door rating. Smoke gaskets work at lower temperatures than intumescent seals - they seal against smoke as soon as the door closes.
Intumescent Seals: Expand when heated to multiple times their original size, sealing door edge gaps during fire events. Invisible under normal conditions but activate at around 300°F (148°C). Required on UL-listed fire doors rated 60 minutes or higher.
Combined with smoke gaskets for complete fire door sealing.
Sound Seals: Acoustic weatherstripping designed to reduce sound transmission through door gaps. Used in offices, conference rooms, music rooms, and healthcare facilities where privacy matters. Typically denser and more compressible than standard weatherstripping.
Meeting Stile Seals: For pair doors (double doors) where two doors meet in the middle. Seals the vertical gap between the two door edges. Important for pair door applications to prevent drafts and pest entry.
Threshold Seals: Some thresholds have integrated seals (rubber or silicone) on the top surface. Door sweep meets the threshold seal for complete sealing. Common on exterior doors where weather sealing is critical.
Fire Door Requirements: NFPA 80 requires specific weatherstripping on fire-rated doors. Products must be UL-listed for the specific fire rating. Using non-listed products invalidates fire rating.
See NFPA 80 for specific requirements.
Coastal Considerations: Florida coastal environments require weatherstripping that handles salt air, humidity, and UV exposure. Silicone-based products outlast vinyl in coastal applications. Upgraded marine-grade products for oceanfront installations.

Why does my door have drafts?
Worn or missing door sweep, perimeter weatherstripping gaps, or frame shift allowing air infiltration. Easy to identify by looking for light gaps around the door. Replacement restores sealing and reduces energy costs.
Do I need weatherstripping on fire doors?
Yes for most rated doors. NFPA 80 requires smoke gaskets and/or intumescent seals on labeled fire doors to prevent smoke passage. Must use UL-listed products specific to the door rating.
Non-listed products invalidate fire rating.
What's the difference between sweeps and perimeter seals?
Sweeps seal the bottom gap between door and threshold. Perimeter seals seal the sides and top of the door to the frame. Complete sealing requires both.
Often installed together for full draft protection.
Can you handle pest control sealing?
Yes. Proper door sealing excludes insects, rodents, and other pests. Brush sweeps, silicone bulb seals, and tight weatherstripping prevent pest entry.
Common service for restaurants, food service, and sensitive applications.
What about sound sealing?
Yes. Acoustic weatherstripping reduces sound transmission through door gaps. Dense compressible products seal better than standard weatherstripping.
Common for conference rooms, offices, and privacy-sensitive applications.
Do you install automatic door bottoms?
Yes. Automatic door bottoms drop down when door closes, retract when door opens. Provides seal when closed but allows ADA threshold clearance when opening.
Common for healthcare and accessible applications.
What brands do you use?
Pemko, NGP (National Guard Products), Hager, Endura, and other commercial weatherstripping manufacturers. Brand selection based on product quality, availability, and match to existing products.
Can you retrofit existing doors?
Yes. Most existing doors can be retrofitted with new sweeps and weatherstripping. Installation involves measuring, selecting products, and mounting without damage to door or frame.
Standard service.
How long does weatherstripping last?
Indoor weatherstripping: 10-20 years. Exterior weatherstripping: 5-15 years depending on exposure. Coastal Florida with salt air and UV: shorter life.
Silicone products last longer than vinyl in coastal applications.
Do you service healthcare facilities?
Yes. Healthcare often requires specific sealing for infection control, privacy, and code compliance. Silicone gaskets for cleanability, sound seals for privacy, and fire door compliance for rated assemblies.
Can you handle multi-door projects?
Yes. Building-wide weatherstripping projects for offices, hotels, schools, and institutional facilities. Volume pricing for large projects.
