Sand mastic in Findon
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you have gaps between timber frames and stone or brick and weathered mastic on the most exposed windows, we can help, whatever the surface.
In and around a place like Findon, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Do you need sand mastic in Findon?
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
Signs it’s time to call us include:
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
If you look after a building such as Portlethen Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in Findon
You will get a clear quote before any work starts. It’s based on:
- The old material and how stubborn it is
- How easy the joints are to reach
- Mould in or behind the old joints
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
When you contact us, these details help:
- A few photos by email, if you can
- The type of property
- What’s wrong with the joints now
- Access, such as stairs, a lift or height

Why it’s worth doing now in Findon
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and finishes neatly against the masonry. 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.
Some things make a job bigger or smaller: 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.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair
- Crumbling stone or brickwork round the window
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.

Looking after it afterwards
To keep the joints looking good and working properly:
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Don’t run silicone over sand mastic
- Renew mastic before redecorating the windows
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Frames and glazing around Findon
Findon is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Aberdeen’s nickname, the Granite City, comes from its stone buildings, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
In the older streets around Portlethen Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Portlethen station? Then any sash windows need sound mastic to keep draughts and rain out.

Findon: your questions answered
Do you work for landlords with property near Portlethen station?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Findon?
Yes. Findon 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.
What should I tell you?
Tell us what needs doing and where. We’ll ask anything else we need to know.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
