Common questions in Chapelton
Is Chapelton within the area you cover?
Yes. Chapelton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Portlethen station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
How much does sand mastic cost in Chapelton?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
How we handle sand mastic in Chapelton
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. Common call-outs are for old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, on tenement windows, timber door frames and brick reveals.
Mastic can only go onto a dry joint, so outside work in Chapelton depends on the weather. Tell us about access to all the windows and doors, upstairs included.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Common problems we fix in Chapelton
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Gaps round a timber door in stone or brick
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
Schools such as Portlethen Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How it works
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before we start. The work usually takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at the surrounds with you and agree the joints to renew.
- 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.
How to prepare
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

How we quote for sand mastic
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Access and height
- The type of sealant required
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
Photos help, but a description is a good start. Please mention:
- Where the job is, and your postcode
- How we’d reach the joints
- What’s wrong with the joints now
- If someone has resealed it before
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Putty and glazing repairs
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Brick reveals
- Timber door frames
- Sash and case windows
- Period & listed homes
- Stone surrounds
- Tenement windows
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.

What else we do in Chapelton
Windows and doors in Chapelton
Chapelton 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 older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Portlethen station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Saint Ternan's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
