DIY Home Draught Proofing

Sash Window Repair Draught Proofing

If you think that we are only a sash window repair company, then you are mistaken. Although repairing and maintaining sash windows is the main thing that we do, we also do a lot of draught proofing. Draught proofing one’s home does not only keep cold air out, it can also save you money.

As much as we want to service anyone who is in need of draught proofing, we have limited resources and cannot fly out to service someone, let’s say in Switzerland. So the best that we can do to help is to give you tips on how to do it. We won’t get any money, but at least the idea of sharing our knowledge to others makes us sleep better at night.
The first thing one must do in draught proofing is to asses where the cold air comes in.

And from our experience, it can be found around;

Floorboards and Skirting Gaps

To resolve this, all you need to do is to use flexible sealants to fill the gaps between floorboards and skirting.

Sash Windows and Patio Doors

For this one, the problem comes from moving surfaces. Movement can create spaces where wind can come in. To resolve this, you need to put a flexible barrier between moving parts. In this case, brush strips.

Window Frames and Doors

Just like the one above, moving surfaces is the culprit. You can use rubber strips or self-adhesive foam.

External Doors

Use screw on external door kits for this one.

Bottom Part of External Doors

To block the passage of cold air, use compression threshold strips. Place the strips at the bottom of the door.


For this one, you can use pivoting brass covers. This way, you get to cover the opening and add a little style to the keyhole.


To draught proof letterboxes, you should use flaps both outside and inside of the letterbox. For the external part, you can use a flap that is of good quality. Look for a durable one with a good spring mechanism. For the internal part, a regular flap would do. Just make sure that it covers the entire hole and sticks to the opening of the letterbox.

Now we have other ways of professionally draught proofing homes, but if we give it to you guys, we might as well close shop.

Anyway, I hope that these tips will help you start your DIY draught proofing. And if your project does not work 100%, remember that we are not only a sash window repair company, we can also keep that chilly winter air out.
