- Gaps behind new kitchen upstands
- Gaps between new skirting and floors

About our new build mastic in Butcher's Cross
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on bathrooms & en suites, kitchens and windows & doors, and the jobs we see most are gaps opening as the house dries out and settles and second-fix sealing on new plots.
For a small place like Butcher's Cross, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

What else we do in Butcher's Cross
Different surfaces, different methods
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 in a matching colour.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Keep pictures and emails about snagging items
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.

Work for landlords, hotels and businesses

Landlords and letting agents in Butcher's Cross can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Butcher's Cross 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: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Old sealant always removed completely
- Approved under the ARBOMaster scheme
- We’re fully insured
- Neat joints and a tidy finish

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Butcher's Cross, the journey is planned in advance: 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 start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Advice
Butcher's Cross questions
Do you work for landlords with property near Crowborough station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Can you do new build mastic in Butcher's Cross?

Should I wait before resealing?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
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.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
