Window Mastic in Craigmarloch
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Craigmarloch. Fully insured, ARBOMaster approved and guaranteed for a year.
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
- Draughty joints inside around the window
How we handle window mastic in Craigmarloch
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have rain getting in at the frame or under the sill and rushed sealant from a window installation, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Craigmarloch depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, it’s backed by our one-year guarantee.

Windows and doors in Craigmarloch
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Craigmarloch is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
For landlords with property near Croy station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why it’s worth doing now in Craigmarloch
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Craigmarloch, water from a failed joint in an older stone home can soak into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- A sash or casement that will not close properly
- A door that needs adjusting, rehanging or new seals
- Condensation trapped between the panes
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep timber frames painted
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Check the mastic once a year
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

What we do, step by step
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes most of a day for a typical house, less for a few frames in most cases. Outdoor work around Craigmarloch 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 confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before

Related advice
Signs you need window mastic in Craigmarloch
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That’s what backing rod is for.
These are the problems we’re asked about most:
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- Gaps left after new windows were fitted
Managing a site like Our Lady's High? Then its window and door frames need their mastic kept sound, just like a home’s.

Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
