Window & door mastic in Whitecross, West Lothian
Problem with your window and door frames in Whitecross? We remove the old material, prepare the joints and seal them properly.
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
How we handle window mastic in Whitecross
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. Either or both can be done. Typical jobs include gaps where the sill meets the wall and rain getting in at the frame or under the sill, on window sills, composite doors and uPVC windows.
Outdoor sealant needs a dry surface, so window work around Whitecross 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, it’s backed by our one-year guarantee.

What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Whitecross: your questions answered
Does the coastal weather in Whitecross affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Linlithgow station. Can you help?
Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Do you come to Whitecross?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Whitecross.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Can you do upstairs windows?
Yes, in most cases. Access is planned before we start.
What we can’t put right
To be straight with you, some problems need a different trade:
- Worn gaskets, brush seals or a door that has dropped
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Whitecross homes and the weather
Whitecross is within about 3 miles of 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 window and door frames, 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 failed outside joints work against that.
If you look after a building such as Linlithgow Academy, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Linlithgow station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Muiravonside Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
