New build mastic for homes and businesses in Kingsdown
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for new-build shower sealant that has already split and joints pulling apart as timber shrinks, on windows & doors, plot handovers and show homes.
In and around Kingsdown, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What else we do in Kingsdown
What we do, step by step
We keep the work tidy and contained to the area we are working on. The job generally takes a few hours in a single home. For a job in Kingsdown, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Why it’s worth doing now in Kingsdown
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In an older home around Kingsdown, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Kingsdown questions
Is Kingsdown within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Kingsdown in your area for new build mastic?
Yes, Kingsdown is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Is the work guaranteed?
Yes. All our work carries our 12-month guarantee.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
How long does new build mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will give you a better idea when we quote.
Landlords, agents and businesses in Kingsdown
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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. Everything old must be removed first.
How we quote for new build mastic
There’s no set price list, because jobs vary so much. What we look at:
- The number and length of the joints
- When we can work, for business premises
- The product the joint needs
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Helping us quote
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- If someone has resealed it before
- The problem you’ve noticed

New build mastic in Kingsdown: local notes
Kingsdown is close to 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. Rainfall in the South East is lower than in much 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 Walmer station, the sealant around baths, showers and frames is worth checking in the first year or two.

Do you need new build mastic in Kingsdown?
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Look out for any of the following:
- Leaking shower tray seals in a new home
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Sealant work across a run of new homes
Around Kingsdown, as everywhere, new build mastic is only as good as the preparation behind it.
