How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

About our new build mastic in Innerleithen
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We are often asked to deal with joints pulling apart as timber shrinks and gaps between new skirting and floors, on windows & doors, kitchens and bathrooms & en suites.
For a place like Innerleithen, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Each job carries a 12-month guarantee, whatever its size.

What else we do in Innerleithen
What we are called out for in Innerleithen
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
It’s worth asking for a quote if you see:
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
Around Innerleithen, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- How hidden problems are handled

What we cannot put right
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Settlement cracks that need a surveyor
- Broken tiles or a split tray
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.

Joints and finishes in Innerleithen homes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Whether the job is in Innerleithen itself or nearby, the right material for each joint matters as much as a neat finish.

Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Follow the cure time we give you
- Record problems with dated photos
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Innerleithen and across the Scottish Borders. Several sites can be quoted together.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
DIY versus a professional finish
If you are set on DIY, put the effort into 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 lifts and traps water and mould underneath. Everything old must be removed first.

Is the work guaranteed?
