- Any mould that needs treating
- Any working-time requirements on site
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

About our new build mastic in Highcliffe
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. We work on kitchens, windows & doors and show homes, and the jobs we see most are skirting joints opening in the first winter and sealant work across a run of new homes.
Homes around Highcliffe range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.

Signs you need new build mastic in Highcliffe
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
If you can see any of these, it’s time to have the joints looked at:
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
For new homes near Winchester station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Highcliffe
Do you cover smaller places like Highcliffe?
Yes. Highcliffe is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Winchester station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours in a single home. We will tell you when we quote.
Do you work for developers?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved and we’ll quote.
Why it’s worth doing now in Highcliffe
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a smaller place like Highcliffe, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Why Highcliffe customers choose us

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
