Common problems we fix in Bilston
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
The problems people generally mention when they call are:
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Rented homes near Eskbank station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- What happens if the job turns out different
- Is VAT in the price?
- Whether the sealant suits the joint
- Who turns up on the day
About our window mastic in Bilston
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We work on aluminium frames, window sills and composite doors, and the jobs we see most are white mastic on grey or black frames and rushed sealant from a window installation.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Why act early in Bilston
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What else we do in Bilston
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Penetrating damp from a failed cavity tray or render
- Condensation trapped between the panes
- Faulty window hardware
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.
Surfaces we seal
- Window sills
- Patio & French doors
- Composite doors
