Window & door mastic in Caddonfoot, Scottish Borders
Window and door frames in Caddonfoot need attention? We cut out the old, prepare the joints and apply the right sealant.
- White mastic on grey or black frames
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
How we handle window mastic in Caddonfoot
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on aluminium frames, window sills and patio & French doors, and people most often call us about gaps between the frame and the inside reveal and rushed sealant from a window installation.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Different surfaces, different methods
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
How the visit works
At the end, we look at the finished work together. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. Somewhere like Caddonfoot may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Landlords, agents and businesses in Caddonfoot
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Make sure the drainage slots aren’t blocked
- Do not aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Quotes for window mastic in Caddonfoot
We quote each job individually. This is what makes a difference:
- The product the joint needs
- Mould in or behind the old joints
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Helping us quote
When you call or email, it’s useful to know:
- The rough size of the job
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- The type of property
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
What we seal
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors
- uPVC windows
- Timber windows & doors
Windows and doors in Caddonfoot
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Historic houses such as Peel House, about 1 mile west, show how far back building around Caddonfoot goes, and older homes nearby need a sealant that suits their walls. Letting a property close to Galashiels station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Is Caddonfoot in your area for window mastic?

Do you work for landlords with property near Galashiels station?

Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before work begins.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How long will my window job take?
A handful of frames is a short visit. You will get a timescale with the quote.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
