About our window mastic in Ballachulish
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you’re dealing with draughts coming in around windows and doors and gaps left after new windows were fitted, we can put it right, on patio & French doors, window sills and aluminium frames alike.
Outdoor sealant needs a dry surface, so window work around Ballachulish is planned around the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by a one-year guarantee.

Common questions in Ballachulish
Is Ballachulish in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Ballachulish is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Ballachulish?
Yes, Ballachulish is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Other services in Ballachulish
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: 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?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. 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.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Outside jobs in Ballachulish need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Ballachulish homes and the weather
Ballachulish 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 window and door frames, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Ballachulish, as everywhere, window mastic is only as good as the preparation behind it.

Aftercare tips
After the cure time, these simple habits help:
- Do not aim a pressure washer at the joints
- Keep timber frames painted
- Make sure the drainage slots are not blocked
- Don’t use solvent cleaners on the joint
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Signs you need window mastic in Ballachulish
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
Look out for any of the following:
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
Whether the job is in Ballachulish itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- How the colour is chosen
- How the joint is cleaned and prepared
- How long the guarantee is
