New-build mastic & snagging in Butlocks Heath, Hampshire
New-build sealant joints in Butlocks Heath need attention? We cut out the old, prepare the joints and apply the right sealant.
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
New build mastic in Butlocks Heath, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, plot handovers and skirting & floors, and the jobs we see most are sealant applied over dusty or wet surfaces and skirting joints opening in the first winter.
Somewhere as small as Butlocks Heath, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job.

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Landlord and commercial work in Butlocks Heath
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Older cottages and farmhouses around Butlocks Heath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
