New build mastic in Wildhern
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you have sealant that never bonded to the surface and shower seals failing in the first year or two, we can help.
Somewhere as small as Wildhern, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, in Wildhern and everywhere else we cover.

Questions from Wildhern
Will you come out to Wildhern?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Andover station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.

New build mastic in Wildhern: local notes

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Record problems with dated photos
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Landlords, agents and businesses in Wildhern
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Somewhere as small as Wildhern, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules

Related advice
Do you need new build mastic in Wildhern?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
The most common problems we see are:
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
Around Wildhern, as everywhere, new build mastic is only as good as the preparation behind it.
