- Hard, cracked sealant around windows

Window mastic for homes and businesses in Sgalpaigh
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Common call-outs are for rushed sealant from a window installation and leaking joints at the ends of sills, on composite doors, timber windows & doors and patio & French 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.

Sgalpaigh: your questions answered
Is window mastic in a coastal place like Sgalpaigh any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Sgalpaigh within the area you cover?
Yes. Sgalpaigh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Where are you based?
We work from Crawley. We cover Sgalpaigh and the rest of Na h-Eileanan Siar.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Common problems we fix in Sgalpaigh
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Common reasons people contact us include:
- Draughts coming in around windows and doors
- Water coming in at the bottom corners of a door
- Gaps where the sill meets the wall
- Draughty joints inside around the window
Around Sgalpaigh, as everywhere, window mastic is only as good as the preparation behind it.

How to look after the new joints
Looking after new joints is easy:
- Clean frames with a soft cloth and soapy water
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Windows and doors in Sgalpaigh
Sgalpaigh 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’s hard on the mastic around window and door frames, especially on the side facing the sea. Island jobs need planning around ferries and the weather, so the more notice, the better.
For jobs in and around Sgalpaigh, choosing the right material for each joint is as important as a tidy finish.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What the job involves on each surface
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
