Window & door mastic in Auchmithie, Angus
Window and door frames in Auchmithie need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
About our window mastic in Auchmithie
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you’re dealing with cracked internal joints between frame and plaster and whistling draughts around closed windows, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we’re called out for in Auchmithie
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 can’t flex. That’s what backing rod is for.
These are the problems we are asked about most:
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
Homes close to 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.

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Timber windows & doors
- uPVC windows
- Window sills
- Composite doors
- Patio & French doors
- Aluminium frames
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes a morning for a couple of windows and a door, and we explain the cure time before we leave. Outdoor work around Auchmithie depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

What window mastic looks like in Auchmithie
Auchmithie is within about 1 mile of 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.
Letting a property close to Arbroath station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Surface by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. Neutral-cure sealant is the safe choice.
Common questions in Auchmithie
Will you come out to Auchmithie?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is window mastic in a coastal place like Auchmithie any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Why act early in Auchmithie
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Auchmithie, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
