Frames and glazing around Lochmaben
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Lockerbie station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Window mastic in Lochmaben
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you have rushed sealant from a window installation and a bead that doesn’t match the frame, we can put it right, on timber windows & doors, patio & French doors and uPVC windows alike.
Outdoor sealant needs a dry surface, so window work around Lochmaben is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

For landlords and businesses
Letting agents and landlords in Lochmaben can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
What happens if it’s left?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a place like Lochmaben, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why Lochmaben clients choose us
- Anti-fungal silicone where joints get wet
- Tidy, careful work
- We are fully insured
- Approved under the ARBOMaster scheme

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A sash or casement that won’t close properly
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Surface by surface
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Signs you need window mastic in Lochmaben
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
- Whistling draughts around closed windows
Around Lochmaben, as everywhere, window mastic is only as good as the preparation behind it.

Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
