Common problems we fix in Killen
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Common reasons people contact us are:
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
For jobs in and around Killen, choosing the right material for each joint is as important as a tidy finish.

About our window mastic in Killen
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before work begins. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. If you’re dealing with mastic that’s falling out in pieces and cracked or shrunken mastic around the frame, we can help, whatever the surface.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Do not aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us about any water getting in
- Let us know about parking restrictions
- Move anything stored near the joints

Common questions in Killen
Is Killen within the area you cover?
Yes. Killen is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Killen for window mastic?
Yes. Our work covers the whole of Scotland, and Killen is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you guarantee window mastic?
Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Windows and doors in Killen
Killen is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Around Killen, as everywhere, window mastic is only as good as the preparation behind it.

Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
