About our new build mastic in Kingsnorth
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on plot handovers, windows & doors and kitchens, and the jobs we see most are skirting joints opening in the first winter and gaps opening as the house dries out and settles.
For a small place like Kingsnorth, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of new build mastic
There’s no set price list, because jobs vary so much. What we look at:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- The size of the job
- Which sealant suits the joint
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- A few pictures by email, if you can
- The address or postcode of the job
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Plot handovers
Developers can send the plot schedule and specification and we will quote. Sealant work across the plot is covered.
The process
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours in a single home, depending on the size of the job. Somewhere like Kingsnorth needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
How to get a quote
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
Why it’s worth doing now in Kingsnorth
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. In a small place like Kingsnorth, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

We’d rather tell you now than do work that will not last, so these are the limits:
- Leaking fittings rather than failed sealant

- Movement caused by a poorly fitted tray or bath

When to call us in Kingsnorth
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
People normally contact us when they notice something like this:
- Second-fix sealing on new plots
- New-build shower sealant that has already split
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
For new homes near Ashford International station, it’s worth checking the sealant early, while snags are still fresh.

When is the sealant fully cured?
It depends on the product and the conditions. We tell you how long to leave it before we go.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
