New-build mastic & snagging in Brockbridge, Hampshire
Plot mastic for developers and snagging failed sealant in new homes for homeowners, landlords and businesses in Brockbridge. Fully insured, ARBOMaster approved and guaranteed for a year.
- Worktop and upstand sealant coming away
- Cracked caulk along new skirting
- Internal frame sealant that has split
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Check bath and shower seals every few months as the house settles
- Do not seal over failed sealant yourself
- Put sealant faults on your snagging list early
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
New build mastic for homes and businesses in Brockbridge
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on bathrooms & en suites, plot handovers and windows & doors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and skirting joints opening in the first winter.
Somewhere as small as Brockbridge, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
New build mastic in Brockbridge: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

When to call us in Brockbridge
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
People normally contact us after spotting something like this:
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
Whether the job is in Brockbridge itself or nearby, the right material for each joint matters as much as a neat finish.
