What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In an older home around Glencaple, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Sand mastic in Glencaple
We work across Glencaple renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have cracked mastic round a front door frame and cement or filler used on old window joints that has cracked, we can help.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a place like Glencaple, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

Advice
Your questions about sand mastic in Glencaple
Do you cover smaller places like Glencaple?
Yes, Glencaple is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Glencaple in your area for sand mastic?
Yes, Glencaple is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Can I do 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 have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
What do you need from me for a quote?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Glencaple homes and the weather
Glencaple is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Whether the job is in Glencaple itself or nearby, the right material for each joint matters as much as a neat finish. In and around Glencaple, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What else we do in Glencaple
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
