How we handle new build mastic in Black Crofts
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include cracks appearing as a new home settles and kitchen sealant that has pulled off the wall, on skirting & floors, plot handovers and bathrooms & en suites.
Work in a place like Black Crofts is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Advice
Joints and finishes in Black Crofts homes
Black Crofts is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Connel Ferry station, it’s worth checking the sealant early, while snags are still fresh.

- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
Around Black Crofts, as everywhere, new build mastic is only as good as the preparation behind it.

Yes. We work across all of Scotland, and Black Crofts is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How do I get a quote for new build mastic in Black Crofts?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with right away
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
