About our sand mastic in Shader
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you have old cement repairs round a window that have failed and window mastic to renew ahead of painting, we can put it right.
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, so the mastic there works hard.
All our work comes with a 12-month guarantee, wherever you are in Na h-Eileanan Siar.

What sand mastic looks like in Shader
Shader is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. On the islands, wind and salt spray are hard on outside sealant.
In and around Shader, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Outdoor work around Shader depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
- Get any rot dealt with first
- Make sure water runs off the sill
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Questions from Shader
Will you come out to Shader?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Does the coastal weather in Shader affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will talk you through it.
How do I get a quote for sand mastic in Shader?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we are fully insured.
Signs you need sand mastic in Shader
Timber frames move with the seasons. The movement cracks the mastic little by little.
Signs it’s time to call us include:
- Modern sealant on a period surround
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
Whether the job is in Shader itself or nearby, the right material for each joint matters as much as a neat finish.

Why act early in Shader
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a place like Shader, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
