A Guide to Door Thresholds, Sweeps, and Weatherstripping
The right doorway components can improve appearance, accessibility, energy efficiency, and protection from the elements. Here is how thresholds, sweeps, and weatherstripping work together.
Better-performing doorways start with the right parts.
Door threshold areas are an essential part of any home. Properly selected and maintained components create smooth transitions, support dependable door operation, reduce drafts, and help protect interior spaces from moisture, dust, and insects.
Solid Hardwood Interior Thresholds
Our unfinished solid hardwood thresholds create clean, attractive transitions between rooms and different flooring materials. They are in stock and ready to ship.
What Is an Interior Threshold?
An interior threshold is a wood transition piece installed in a doorway between two adjoining flooring surfaces, such as carpet and hardwood, tile and laminate, or floors with slightly different heights.
- Covers gaps between adjacent floors
- Creates a clean, finished appearance
- Helps reduce tripping hazards
- Minimizes drafts at door openings
- Provides a solid base for door sweeps
Unfinished for a Custom Look
All of our interior thresholds are made from unfinished solid wood. They can be stained or painted to coordinate with your flooring, doors, trim, and overall interior design.
ADA and Low-Profile Threshold Options
For doorways that require easier mobility or a reduced step height, low-profile thresholds provide a smoother transition.
Accessibility Friendly
ADA-compliant interior thresholds are designed to stay within applicable height limits while creating a smooth transition.
Minimal Step Height
A lower profile is helpful where wheelchair access, walkers, or easier movement between rooms is important.
Solid Hardwood Construction
Durable hardwood provides a dependable transition that can be finished to match the surrounding space.
How to Choose the Right Interior Threshold
Consider the flooring height, doorway width, and desired finish before selecting a threshold.
Match Floor Heights
Choose a profile that properly bridges the height difference between adjoining floors for a clean, level transition.
Consider the Width
Wider thresholds can accommodate larger transitions or create a broader decorative seam between rooms.
Select the Finish
Stain or paint the unfinished hardwood to complement your flooring, doors, trim, and interior color palette.
Exterior Door Thresholds
A properly installed exterior threshold helps reduce drafts, limit water infiltration, and create a clean transition between indoor and outdoor spaces.
Key Exterior Threshold Features
Adjustable components and moisture-resistant materials help provide a reliable fit and long-lasting exterior performance.
Composite Adjustable Cap
The cap can be raised or lowered during installation to align with the door's bottom seal and improve weather protection.
Moisture-Resistant Base
The composite base is engineered to resist moisture, prevent rot, and withstand years of exterior use.
Oversized for a Custom Fit
Thresholds are supplied slightly oversized so they can be trimmed on-site for a more accurate installation.
Benefits of a Quality Exterior Threshold
The right materials and fit can help improve durability, sealing, and overall door performance.
Long-Lasting Materials
Composite caps and bases, along with anodized aluminum components, help resist moisture, wear, and everyday exposure.
Adjustable Installation
On-site trimming and cap adjustments allow the threshold to be customized to the specific door opening.
Improved Sealing Performance
When paired with compatible sweeps and weatherstripping, the threshold helps reduce drafts, moisture, dust, and insects.
Multiple Size Options
Available sizes are designed to fit many standard residential exterior door openings.
Door Bottom Sweeps
Door sweeps help close the gap between the bottom of the door and the threshold.
How Door Sweeps Work
Door bottom sweeps typically feature flexible vinyl fins or fingers that make contact with the threshold when the door is closed.
What They Help Block
- Drafts and outside air
- Dust and outdoor debris
- Moisture
- Insects
- Energy loss through door gaps
Door Weatherstripping
Weatherstripping creates a tight seal along the sides and top of the door frame to improve comfort and energy efficiency.
What Is Included
The weatherstripping set includes three 8-foot, or 96-inch, sections that can be trimmed to fit the door frame.
Product Benefits
- Seals the sides and top of the door
- Helps improve energy efficiency
- Blocks drafts, moisture, dust, and insects
- Springs back after compression
- Trims easily to fit the door frame
