Common call-outs are for gaps behind new kitchen upstands and smeared, uneven beads picked up at snagging, across windows & doors, show homes and plot handovers.
Small business units and shops in a town like Whitstable have floors that take heavy wear. Threshold and floor joints are best resealed before their edges start breaking away.

What new build mastic looks like in Whitstable
Whitstable is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Whitstable, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Whitstable station, the sealant around baths, showers and frames is worth checking in the first year or two.

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Which sealant suits the joint
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- Where the job is, and your postcode
- How we’d reach the joints
- Whether it has been sealed before
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
The process
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours in a single home.

- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.

Landlord and commercial work in Whitstable

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Aftercare tips
A little care helps the new joints last. Our advice:
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Why act early in Whitstable
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a family home in Whitstable, a failed seal around a bath or a frame lets water into places you cannot see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
