Oxton: your questions answered
Is Oxton in your area for external mastic?
Yes, Oxton is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Will you come out to Oxton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Are you fully insured?
Yes, we are fully insured for every job we do.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
External mastic in Oxton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we don’t skip that step. If you are dealing with moss and dirt in joints with no sealant left and damp patches traced to an open external joint, we can put it right, on copings & trims, façade panels and brickwork movement joints alike.
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.
Big or small, it’s backed by our 12-month guarantee in Oxton and across the Scottish Borders.

When to call us in Oxton
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
For jobs in and around Oxton, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- How the colour is chosen
- Is the old sealant removed completely?
How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access from start to finish. Outside jobs in Oxton need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Mention any tricky access
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

What affects the cost of external mastic
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- Access and height
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
When you contact us, these details help:
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- Any access issues, like height or stairs

Aftercare tips
Looking after new joints is easy:
- Walk round the building once a year and look at the joints
- Have failed joints looked at early
- Point out the joints to other trades
- Keep high-pressure jets off the joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Landlords, agents and businesses in Oxton
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Damp that isn’t coming from the joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

External mastic in Oxton: local notes
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. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
