What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
New build mastic in Deaconsbank
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on bathrooms & en suites, plot handovers and show homes, and the jobs we see most are sealant that never bonded to the surface and second-fix sealing on new plots.
In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. For a flat in Deaconsbank, a flexible sealant copes with that movement where filler would crack.
Each job carries a 12-month guarantee, whatever its size.

Why act early in Deaconsbank
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Wind-driven rain gets into any failed joint on the outside of a city building, and in Deaconsbank, damp can spread through stone and plaster before anyone sees it.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Not at all. The area is protected while we work and cleaned up afterwards.
Signs you need new build mastic in Deaconsbank
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Keep an eye out for any of the following:
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
For new homes near Patterton station, it’s worth checking the sealant early, while snags are still fresh.

Joints and finishes in Deaconsbank homes
The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Deaconsbank, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re 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 does not work out, we can still put it right.
What we cannot put right
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
