How to Seal Door Gaps: A Simple Guide for Singapore Homes
Noticed light peeking through your door frame? Feeling a draft even when the door is shut? These are signs of unsealed door gaps — and they can lead to higher electricity bills, unwanted pests and street noise creeping into your home.
Here’s a quick guide on how to seal door gaps effectively and affordably.
Step 1: Identify Where the Gap Is
Start by checking:
• Under the door (threshold area)
• Sides of the door
• Top of the door frame
Use a torch or daylight to spot visible gaps. You can also feel for air leaks with your hand.
Step 2: Choose the Right Sealing Method
For Gaps Under the Door:
• Automatic Drop-Down Door Seals – A premium option that seals only when the door is shut.
• Door sweeps or rubber draft stoppers – Easy to install, ideal for blocking cold air and insects.
For Side or Top Gaps:
• Adhesive weatherstripping (rubber or foam) – A quick fix to cushion and seal.
• Magnetic seals – Great for soundproof doors.
Step 3: Install the Seal
• Clean the surface.
• Measure and cut the seal to fit the door edges.
• Apply adhesive backing or screw in the seal based on type.
• Installation can usually be done with basic tools — or reach out to a professional for a neater finish.
