New homes and floors in Kingsnorth
Kingsnorth is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Kingsnorth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Questions from Kingsnorth
Can you help a landlord with a rental near Gillingham (Kent) station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Kingsnorth?
Yes. Kingsnorth is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Landlord and commercial work in Kingsnorth
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. We can quote a run of properties together.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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. Older cottages and farmhouses around Kingsnorth can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

When to call us in Kingsnorth
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Keep an eye out for any of the following:
- Joints pulling apart as timber shrinks
- Sealant work across a run of new homes
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
For new homes near Gillingham (Kent) station, it’s worth checking the sealant early, while snags are still fresh.
