External mastic in Fintry, done properly
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with failed seals between different materials and weathered mastic that no longer stretches, we can help.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
Whatever the size of the job, you get the same one-year guarantee in Fintry and across Stirling.

External mastic in Fintry: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.

What else we do in Fintry
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In an older home around Fintry, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- 4.9 on Google from 180+ five-star reviews
- We never seal over old sealant
- Neat joints and a tidy finish
- White, clear, grey or another colour, product permitting
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Signs you need external mastic in Fintry
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
Signs it’s time to call us include:
- Failed seals between different materials
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
- Panel joints letting water in
Homes close to Old Fintry Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- Whether you can choose the colour
- What happens if the job turns out different
- How long the guarantee is
- Whether they seal over old material or remove it
Fintry: your questions answered
Do you cover Fintry for external mastic?
Yes. Our work covers the whole of Scotland, and Fintry is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Is there a guarantee on external mastic in Fintry?
All our work, in Fintry and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do you work for letting agents?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What is backing rod for?
That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
What sealant work cannot fix
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Render that is blown, hollow or coming away
- Adding movement joints to masonry that has none
- Damp that isn’t coming from the joint
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before booking.
Surfaces we seal
- Copings & trims
