External mastic for homes and businesses in Bower
A movement joint is only as good as its depth. 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 are dealing with moss and dirt in joints with no sealant left and joints pointed up with cement by mistake, we can help.
External sealant needs dry surfaces, so outdoor work around Bower is planned around the weather. Let us know about access to every wall and roofline.
Whatever the size of the job, you get the same 12-month guarantee.

Landlord and commercial work in Bower
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and agents in Bower can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Your questions about external mastic in Bower
Can you do external mastic in Bower?
Yes. Our work covers the whole of Scotland, and Bower is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Will you come out to Bower?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.

Outside joints around Bower
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In and around Bower, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
Bower is about 9 miles east of Thurso, in Highland. Every kind of property in Bower is covered for external mastic. The work is guaranteed for a year. Bower is one of 253 places in Highland we cover.
Work in KW1 works the same way as everywhere else we cover. External mastic is available to properties on Auchorn Square and Thura Place and the roads around them.

What happens if it’s left?
A failed movement joint lets water into the wall. Resealing early keeps the job to the joint itself, rather than the wall around it. In a place like Bower, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How the visit works
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Outside jobs in Bower need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

When to call us in Bower
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
Signs it’s time to call us include:
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
- Failed sealant between panels on a façade
- Moss and dirt in joints with no sealant left
Homes close to Bower Parish Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
