How we handle window mastic in Brinian
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have a bead that doesn’t match the frame and water coming in at the bottom corners of a door, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wipe condensation off the frames
- Keep timber frames painted
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks usually 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.
How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Composite doors
Front doors take the weather head on. Those corners get the most care.
When something else is needed
To be straight with you, some problems need a different trade:
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Patio & French doors
- Composite doors
- Aluminium frames
- uPVC windows
- Window sills
- Timber windows & doors
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Around Brinian, 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 is why we ask a few questions first.

Brinian: your questions answered
Does the coastal weather in Brinian 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.
Do you cover Brinian for window mastic?
Yes. We work across all of Scotland, and Brinian is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Where do you work from?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Frames and glazing around Brinian
Brinian is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For jobs in and around Brinian, choosing the right material for each joint is as important as a tidy finish.

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Whether the work is at height
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
You don’t need to know the technical terms. Just tell us:
- If someone has resealed it before
- Where the property is
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
What we are called out for in Brinian
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
The most common problems we see are:
- Black, perished sealant on frames
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
In and around Brinian, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
