New build mastic for homes and businesses in Plasterfield
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. Typical jobs include untidy sealant flagged on a snagging list and kitchen sealant that has pulled off the wall, across skirting & floors, bathrooms & en suites and windows & doors.
Work in a place like Plasterfield is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
When to call us in Plasterfield
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Most people get in touch when they notice something like this:
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
Around Plasterfield, as everywhere, new build mastic is only as good as the preparation behind it.

Advice
More services for Plasterfield
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
Landlord and commercial work in Plasterfield
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured for the work.
Why act early in Plasterfield
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In an older home around Plasterfield, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

Joints and finishes in Plasterfield homes
Plasterfield is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Plasterfield 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.
For jobs in and around Plasterfield, choosing the right material for each joint is as important as a tidy finish.
