If you live in an older home like mine (our house is a Victorian gem), you’re probably no stranger to draughts. They creep in under doors, whistle through sash windows, and rise up through the gaps in your floorboards. While charming period features can be beautiful, they often come with the challenge of keeping your home warm — and your heating bills manageable.
One of the worst culprits in our house was the uncarpeted floorboards in the downstairs living areas. Though they looked stunning, but the gaps between the boards let cold air flood in, making the floors icy and the whole space uncomfortable during winter.
If you’re facing the same problem, don’t worry! I’ve found a simple, cost-effective solution to fix draughty floorboards without spending a fortune or enduring a messy, time-consuming project.
Why Fix Draughty Floorboards?
Fixing draughty floorboards is about more than just comfort. Here’s why it’s worth tackling this issue:
- Lower Heating Bills: By sealing gaps, you’ll reduce heat loss and make your home more energy-efficient, cutting down on your heating costs.
- Improved Comfort: No more chilly feet or cold drafts in your living spaces.
- Preserve Your Home’s Style: You can keep the charm of exposed wooden floors while making them practical for modern living.
How to Fix Draughty Floorboards: My Top Solution
After exploring numerous options like papier-mâché, wood filler, cork, and foam, I stumbled upon a product that worked wonders for us: STOPGAP. This ingenious plastic strip is designed specifically for sealing gaps between floorboards, and it’s a game-changer.
Here’s how it works:
- Bend and Insert: Take the StopGap strip, bend it in half lengthwise (so it forms a “V”), and push it into the gap between the floorboards with the “V” facing downward.
- Secure in Place: Use a credit card or a similar flat tool to press the strip further down until it’s just a few millimeters below the surface of the floor.

- Vacuum Regularly: While the StopGap is highly effective, fine dust and fluff can settle in the gaps over time. A quick vacuum directly over the gaps will keep them clean. But if it does get really clogged up with dirt it’s easy to remove, wipe down and reinstall.
Not only does StopGap create a neat finish, but it’s also durable, easy to install, and much more effective than newspaper or makeshift fillers. Plus, it can be used to seal draughty skirting boards and windows, making it a versatile solution for keeping your home warm.

Other Areas to Draught-Proof
Once you’ve sealed your floorboards, consider tackling other common draught sources to make your home even cozier. Doors, windows, and chimneys are all worth addressing to maximize warmth and minimize heating costs.

Fixing draughty floorboards doesn’t have to be an expensive or overwhelming task. With StopGap, you can enjoy the beauty of your wooden floors without compromising on comfort or energy efficiency. It’s a small investment that delivers big results, helping you create a warmer, more inviting home.

Looks like a good idea! We were in a Victorian home before and it can get really cold. I hadn’t heard of this product before.
Given that our dog has destroyed the hallway carpet, we may resort to painted wooden floors very soon! Thanks for a great post
That’s a really clever idea. I’d love wooden floors but they wouldn’t work in our house.
Oh wow that IS a clever idea! I’ve never heard of it before. We have floorboards in most of our downstairs, I’m going to take a look at this! x
