Sand mastic in Powmill
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on sash and case windows, timber door frames and stone surrounds, and people most often call us about mastic dropping out of the joint and open joints round the window box.
Mastic can only go onto a dry joint, so outside work in Powmill depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In an older home around Powmill, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- Over 20 years’ experience
- Every job guaranteed for a year
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants

Questions from Powmill
Can you do sand mastic in Powmill?
Yes, Powmill is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Is Powmill within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will advise.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Frames and glazing around Powmill
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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For jobs in and around Powmill, choosing the right material for each joint is as important as a tidy finish.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
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 the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we are called out for in Powmill
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they normally need raking out.
Keep an eye out for any of the following:
- Window mastic to renew ahead of painting
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
In and around Powmill, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
