Whether the job is in Elsted itself or nearby, the right material for each joint matters as much as a neat finish. Around Elsted, as everywhere, new build mastic is only as good as the preparation behind it.

How we handle new build mastic in Elsted
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Typical jobs include gaps behind new kitchen upstands and frame joints opening as the plaster dries, across show homes, skirting & floors and windows & doors.
Older homes in small places like Elsted often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Looking after it afterwards
Aftercare is simple:
- Get a leaking seal dealt with straight away
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work normally takes a few hours in a single home. Somewhere like Elsted needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Older cottages and farmhouses around Elsted can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Common questions in Elsted
Is there a guarantee on new build mastic in Elsted?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Elsted for new build mastic?
Yes. We work across London and the South East, and Elsted is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
How much does new build mastic cost in Elsted?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
How long will you be here?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we will say how long yours will take.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
