- Kitchen sealant that has pulled off the wall
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
- Record problems with dated photos
- Resist patching a failed seal with a tube from the DIY shop
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
New build mastic in Dunning
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for cracks appearing as a new home settles and sealant work across a run of new homes, on windows & doors, bathrooms & en suites and skirting & floors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
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.

FAQs for Dunning
What guarantee comes with new build mastic in Dunning?
All our work, in Dunning and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Dunning for new build mastic?
Yes. Our work covers the whole of Scotland, and Dunning 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 price.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that doesn’t work out, we are happy to quote with our 12-month guarantee.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we’ll do.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. Somewhere like Dunning may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Related advice
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
