FAQs for Hamilton West
Is Hamilton West in your area for external mastic?
Yes, Hamilton West is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Will you come out to Hamilton West?
Yes. Hamilton West is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you use backing rod?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
External mastic in Hamilton West
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. If you have cracked joints where brick meets render or frames and movement joints with cracked, split or missing sealant, we can put it right.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the building for a typical job. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last so it’s worth doing right. 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too in Hamilton West and across South Lanarkshire. Several sites can be quoted together.
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When to call us in Hamilton West
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Any of these means the joints need attention:
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Weeds or debris growing in open joints
- Panel joints letting water in
In the older streets around Hamilton North Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Walls and rooflines in Hamilton West
The west of Scotland is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
Rented homes near Hamilton West station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Holy Cross High School, larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
