About our new build mastic in Westergate
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on show homes, kitchens and plot handovers, and the jobs we see most are messy sealant that spoils new finishes and worktop and upstand sealant coming away.
For a new home in or near Westergate, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
Questions from Westergate
Do you cover smaller places like Westergate?
Yes, smaller places are covered as well as towns. We work across 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 Barnham station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish before we begin.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Do you need new build mastic in Westergate?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Common reasons people contact us are:
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
In and around Westergate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What to tell us for a quote

Keeping the joints in good condition
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
