Sand mastic in Kilkerran
We work across Kilkerran renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on stone surrounds, brick reveals and period & listed homes, and common reasons people get in touch are silicone on a period window that looks wrong and open joints round the window box.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Sand mastic in Kilkerran: local notes
Kilkerran 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 older windows and doors, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Kilkerran, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For an older house near a landmark such as Kilkerran Old Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Kilkerran is in Argyll and Bute. Jobs in Kilkerran get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Across Argyll and Bute, we cover 118 places, and Kilkerran is one of them. We also work in Glasgow, about 60 miles from Kilkerran.
Work in PA28 works the same way as everywhere else we cover. You’ll find streets such as Hutcheon Road, Kilkerran Road and Ardnacraig Avenue, all of which we cover. We also cover the places around Kilkerran: Askomill (1 mile north), Campbeltown (1 mile north-west), Drumlemble (4 miles west), West Darlochan (5 miles north-west) and Southend (7 miles south). If you are somewhere remote, a little more planning is needed, so mention it when you ask for a quote.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several. Somewhere like Kilkerran 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

Aftercare tips
A little care helps the new joints last. Our advice:
- Make sure water runs off the sill
- Look over the window mastic once a year
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- The type of sealant required
- How many areas need sealing
- The number and length of the joints
- Mould in or behind the old joints
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Common questions in Kilkerran
Is Kilkerran within the area you cover?
Yes, Kilkerran is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Kilkerran affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Is sand mastic better than silicone for my windows?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does sand mastic take?
A typical job takes anything from a few hours to a full day, depending on how many windows, including the preparation. Your quote will say how long we expect yours to take.

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
