Your questions about external mastic in Tarsappie
I let a flat near Perth station. Can you help?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Is Tarsappie within the area you cover?
Yes. Tarsappie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How much does external mastic cost in Tarsappie?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
External mastic for homes and businesses in Tarsappie
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. Typical jobs include cracked joints where brick meets render or frames and damp patches traced to an open external joint, across copings & trims, joints between brick and frames and concrete & block.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
You get a one-year guarantee, the same in Tarsappie as everywhere else we work.

What affects the quote in Tarsappie
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- The product the joint needs
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- A few photos by email, if you can
- If someone has resealed it before
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, drop us a line at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.

Walls and rooflines in Tarsappie
Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Tarsappie, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
After the cure time, these simple habits help:
- Tell anyone working on the walls about the movement joints
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Keep high-pressure jets off the joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Signs you need external mastic in Tarsappie
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint.
The most common problems we see are:
- Old sealant gone brittle and cracked
- Weeds or debris growing in open joints
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
If you let a flat or house near Perth station, split movement joints are easy to miss on a rental until damp shows inside.

Why act early in Tarsappie
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation. Outdoor work around Tarsappie 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.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
