The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run 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, and the visit is planned around that.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

About our new build mastic in St John's Town of Dalry
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on windows & doors, plot handovers and kitchens, and the jobs we see most are gaps between new skirting and floors and frame joints opening as the plaster dries.
For a place like St John's Town of Dalry, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
To keep the joints looking good and working properly:
- Raise failed sealant with the developer while you are covered
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
New build mastic in St John's Town of Dalry: local notes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. St John's Town of Dalry is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Around St John's Town of Dalry, as everywhere, new build mastic is only as good as the preparation behind it.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
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.
Do you need new build mastic in St John's Town of Dalry?
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we are asked about most:
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
For jobs in and around St John's Town of Dalry, choosing the right material for each joint is as important as a tidy finish.

What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a place like St John's Town of Dalry, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- We never seal over old sealant
- Every job guaranteed for a year
- We agree the colour with you first

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
- Plumbing faults behind the sealant
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
