Frequently Asked Questions
Why is my door still drafty after adding weatherstripping?
Most often it's due to an improper seal or incorrect product for the gap size. Check that the surface was cleaned before applying adhesive strips, that the strip thickness matches the gap, and that the sweep is installed flush. For very uneven gaps, combining perimeter weatherstripping with a mechanical door sweep at the bottom often fixes remaining drafts.
Can I install weatherstripping myself or do I need a pro?
Yes—most adhesive silicone strips, T-shaped seals, and slide-on sweeps are designed for DIY installation with basic tools (scissors, screwdriver, measuring tape). Mechanical sweeps that require drilling are straightforward but take a bit more care to align; follow the included instructions and measure precisely.
How long does weatherstripping usually last?
Lifespan depends on material and exposure. Adhesive silicone strips and quality T-seals can last several years indoors; exterior sweeps with mechanical mounts tend to be more durable. Expect to inspect seals annually—replace if cracked, compressed, or if drafts return.
