Sand mastic for homes and businesses in Kenmore
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you have a silicone bead on a sash window that spoils the look and mastic dropping out of the joint, we can help, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Whatever the size of the job, you get the same one-year guarantee.

Frames and glazing around Kenmore
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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 Kenmore, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

What happens on the day
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Outdoor work around Kenmore depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Related advice
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep sills and gutters clear so water drains away
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Kenmore questions
Do you cover Kenmore for sand mastic?
Yes, Kenmore is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Kenmore within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What does sand mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
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.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Common problems we fix in Kenmore
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they normally need raking out.
Look out for these signs:
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
For jobs in and around Kenmore, choosing the right material for each joint is as important as a tidy finish.
