How the job changes by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
New build mastic for homes and businesses in Northfield
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on skirting & floors, bathrooms & en suites and windows & doors, and people most often call us about sealant that never bonded to the surface and kitchen sealant that has pulled off the wall.
Older tenement flats normally have timber floors on joists, so skirting joints open and close through the year. For a flat in Northfield, a flexible sealant copes with that movement where filler would crack.
A one-year guarantee comes with the work, just as it does everywhere we cover.

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 Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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 does not work out, we can still put it right.
Joints and finishes in Northfield homes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Northfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Act quickly if a seal starts to leak
- Avoid running a DIY bead over the old one
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.

Advice
Signs you need new build mastic in Northfield
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
- Sealant that never bonded to the surface
For new homes near Aberdeen station, it’s worth checking the sealant early, while snags are still fresh.
