What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

New build mastic for homes and businesses in Willey Green
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you are dealing with frame joints opening as the plaster dries and plot mastic for developers ahead of handover, we can help, whatever the surface.
For a small place like Willey Green, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, you get the same one-year guarantee in Willey Green and across Surrey.

Your questions about new build mastic in Willey Green
Do you cover Willey Green for new build mastic?
Yes. We work across London and the South East, and Willey Green is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like Willey Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Can I do it myself?
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.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items. We’ll flag anything that needs another trade.
How it works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Willey Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

Related advice
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Looking after it afterwards
So the new joints stay in good condition:
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
Landlord and commercial work in Willey Green
Landlords and agents in Willey Green can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In a small place like Willey Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
