Window & door mastic in Athelstaneford, East Lothian
Window mastic for Athelstaneford and the surrounding area: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Damp patches on the reveal after heavy rain
Aftercare tips
Aftercare is simple:
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
- Avoid harsh chemicals near the mastic
- Keep timber frames painted
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
About our window mastic in Athelstaneford
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on patio & French doors, timber windows & doors and uPVC windows, and people most often call us about untidy mastic left by window fitters and old mastic that has gone black or come away.
Outdoor sealant needs a dry surface, so window work around Athelstaneford is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Big or small, you get the same one-year guarantee in Athelstaneford and across East Lothian.

Landlords, agents and businesses in Athelstaneford
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Landlords and letting agents in Athelstaneford 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.
Common problems we fix in Athelstaneford
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The most common problems we see are:
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
For an older house near a landmark such as Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What the job involves on each surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Outdoor work around Athelstaneford 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.

- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.

Frames and glazing around Athelstaneford
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against 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 landlords with property near Drem station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When it isn’t the sealant

- Damp coming through the wall itself rather than the frame joint

Surfaces we seal
- Aluminium frames
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Window sills
- Composite doors
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
