External mastic in Patna: 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. Patna is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain.
For jobs in and around Patna, choosing the right material for each joint is as important as a tidy finish. Around Patna, as everywhere, external mastic is only as good as the preparation behind it.

External mastic for homes and businesses in Patna
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you’re dealing with weeds or debris growing in open joints and joints pointed up with cement by mistake, we can help, whatever the surface.
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.
Every job is covered by our one-year guarantee.

How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the building. For a place like Patna, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Why act early in Patna
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Your questions about external mastic in Patna
What guarantee comes with external mastic in Patna?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Patna for external mastic?
Yes. Our work covers the whole of Scotland, and Patna is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can a movement joint be filled with mortar?
No. Cement or mortar can’t stretch and the joint fails. If it has already been filled, we can generally cut it out and reseal it.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can new sealant go over the old?
No. The old sealant always comes out first.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together.
How we quote for external mastic
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The size of the job
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Asking for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- The problem you’ve noticed
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, send an email to info@mrmastic.co.uk.
Can I do it myself?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before sealing.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Get split or bare joints resealed while the damage is small
- Do not let climbing plants root in the sealant
- Deal with leaking gutters that soak the joints below
- Never let anyone fill a movement joint with mortar
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
