About our sand mastic in Cowie
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you’re redecorating. Typical jobs include failed mastic on an exposed elevation and silicone on a period window that looks wrong, on stone surrounds, period & listed homes and sash and case windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Your questions about sand mastic in Cowie
Do you work for landlords with property near Stonehaven station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Cowie?
Yes. Cowie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
What guarantee comes with the work?
Every job comes with our one-year guarantee, and we are fully insured.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What sand mastic looks like in Cowie
Cowie is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For an older house near a landmark such as Chapel of St. Mary and St. Nathalan, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Mackie Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep sills and gutters clear so water drains away
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at the surrounds with you and agree the joints to renew.
- 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.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
