How we handle external mastic in Clarencefield
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on copings & trims, brickwork movement joints and concrete & block, and people most often call us about damp patches traced to an open external joint and joints where the bead has come unstuck.
Outside joints can only be sealed when they’re dry, so work in Clarencefield depends on the weather. Let us know about access to every wall and roofline.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the damage spreads beyond the joint. In an older home around Clarencefield, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Why Clarencefield clients choose us
- More than 20 years in sealant work
- A sealant colour to suit the surroundings
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or another colour, product permitting
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Show decorators and builders where the movement joints are
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Keep soil, plants and ivy away from the joints
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

What affects the quote in Clarencefield
Call for a quick quote. The main things that affect it are:
- The type of sealant required
- The old material and how stubborn it is
- Whether the work is at height
- How much there is to do
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
What to tell us when you ask for a quote:
- The rough size of the job
- Any previous sealing or DIY work
- A few photos by email, if you can
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Outside jobs in Clarencefield need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

Clarencefield: your questions answered
Is Clarencefield in your area for external mastic?
Yes, Clarencefield is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
Will you come out to Clarencefield?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
Clarencefield buildings and the weather
Clarencefield is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
In the older streets around Ruthwell Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Around Clarencefield, as everywhere, external mastic is only as good as the preparation behind it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
