For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Sand mastic in Port Ellen, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include gaps where the frame meets the masonry and mastic dropping out of the joint, across brick reveals, stone surrounds and sash and case windows.
Outdoor sealant needs a dry surface, so window work around Port Ellen is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
You’re covered for a year from the day we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Your questions about sand mastic in Port Ellen
Can you do sand mastic in Port Ellen?
Yes. We work across all of Scotland, and Port Ellen is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Is Port Ellen within the area you cover?
Yes. Port Ellen 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.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints. We will confirm how long when we quote.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Cracked or broken glass
- Whether work needs listed building consent
- Sash cords, weights and draught-proofing of the sashes
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Tenement windows
- Stone surrounds

- Timber door frames
- Period & listed homes

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sand mastic in Port Ellen: local notes
Port Ellen 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. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
For an older house near a landmark such as St John's Church (Port Ellen), the joint between an old wall and a newer frame is normally the first place rain gets in.
Port Ellen (Gaelic: Port Eilein) is in Argyll and Bute. We provide sand mastic to homes and businesses in Port Ellen and the surrounding area. Port Ellen is one of 118 places in Argyll and Bute where we work. We also work in Glasgow, around 76 miles away.

Do you need sand mastic in Port Ellen?
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Any of these means the joints need attention:
- Mastic that needs renewing before redecorating
- Gaps round a timber door in stone or brick
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
Around Port Ellen, as everywhere, sand mastic is only as good as the preparation behind it.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
- Plan mastic work ahead of painting
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it.

Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a place like Port Ellen, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
