External mastic for homes and businesses in Loaningfoot
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. If you have sealant that has lost its bond to the brick or render and rain getting behind render or cladding at a joint, we can put it right.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
There’s a 12-month guarantee on every job, large or small.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Leave the joints unpainted unless we have said otherwise
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Access and height
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Where the property is
For a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Outside jobs in Loaningfoot need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.

What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Outside joints around Loaningfoot
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you let a flat or house near Dumfries station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Your questions about external mastic in Loaningfoot
Do you work for landlords with property near Dumfries station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Will you come out to Loaningfoot?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you match the colour of my brickwork?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Common problems we fix in Loaningfoot
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Common reasons people contact us are:
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
- Joints where the bead has come unstuck
For site and facilities teams at buildings such as Dumfries High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
