FAQs for Highstead
Do you cover smaller places like Highstead?
Yes. Highstead is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Herne Bay station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Are you fully insured?

That depends on the sealant. Some smell for a while, some hardly at all.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they won’t put it right, we will cut it out and reseal it.
What does new build mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
How we handle new build mastic in Highstead
Across Highstead, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on kitchens, bathrooms & en suites and windows & doors, and people most often call us about frame joints opening as the plaster dries and messy sealant that spoils new finishes.

What new build mastic looks like in Highstead
Highstead is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Herne Bay station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Highstead, as everywhere, new build mastic is only as good as the preparation behind it.

- The failed sealant is removed completely down to clean surfaces.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. 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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- A tray or bath that is not properly supported, until it’s fixed
- Broken tiles or a split tray
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Highstead, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How the job changes by surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
