Common call-outs are for kitchen sealant that has pulled off the wall and skirting joints opening in the first winter, on skirting & floors, kitchens and show homes.
Work in a place like Wiston is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Every job comes with our 12-month guarantee.

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a place like Wiston, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Common questions in Wiston
Do you cover smaller places like Wiston?
Yes. Wiston is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Wiston for new build mastic?
Yes. We work across all of Scotland, and Wiston is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
When to call us in Wiston
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Look out for any of the following:
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
- Joints pulling apart as timber shrinks
- Leaking shower tray seals in a new home
For jobs in and around Wiston, choosing the right material for each joint is as important as a tidy finish.

What affects the quote in Wiston
Jobs vary more than people expect. What affects the quote:
- The size of the job
- Which sealant suits the joint
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
To make quoting easier, let us know:
- Where the property is
- Whether it has been sealed before
- How we’d reach the joints
- The problem you’ve noticed
For a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before work begins.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Record problems with dated photos
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
