Window mastic in Lochearnhead: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Lochearnhead, as everywhere, window mastic is only as good as the preparation behind it.

About our window mastic in Lochearnhead
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. If you’re dealing with hard, cracked sealant around windows and rushed sealant from a window installation, we can help, on window sills, timber windows & doors and aluminium frames alike.
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.
There’s a 12-month guarantee on every job, whatever its size.

When to call us in Lochearnhead
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Common reasons people contact us are:
- A bead that doesn’t match the frame
- Mastic that’s falling out in pieces
- Mastic that has split away from the wall
- Cold air getting in at the frame edge
Homes close to St Angus Episcopal Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include

- How the surfaces are prepared before sealing
- Whether you can choose the colour
- Whether VAT is included
Why it’s worth doing now in Lochearnhead
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. 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.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Lochearnhead: your questions answered
Do you cover smaller places like Lochearnhead?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with window mastic in Lochearnhead?
All our work, in Lochearnhead and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Do you have insurance?
Yes. We’re fully insured.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Honest limits
We won’t take on work that will not last, so these are the limits:
- A sash or casement that won’t close properly
- Soft or decayed wood in the frame
- Damp coming through the wall itself rather than the frame joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Lochearnhead may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
