Surface by surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Window mastic in Wigtown
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before work begins. Just email us at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached for window mastic in Wigtown. Common call-outs are for draughty joints inside around the window and cracked or shrunken mastic around the frame, on window sills, aluminium frames and composite doors.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job is covered by our one-year guarantee.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. For a place like Wigtown, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
How to get a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

Signs you need window mastic in Wigtown
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.
People usually contact us after spotting one of these:
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
Homes close to Sacred Heart Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Who turns up on the day
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
- How long the guarantee is
What we can’t put right
In fairness, some problems need a different trade:
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. 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.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet

Frames and glazing around Wigtown
Wigtown is within about 1 mile of 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.
In and around Wigtown, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Questions from Wigtown
Does living near the coast affect window mastic in Wigtown?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you cover Wigtown for window mastic?
Yes. We work across all of Scotland, and Wigtown is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
