New build mastic in Wivelsfield, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on bathrooms & en suites, skirting & floors and kitchens, and common reasons people get in touch are leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall.
Older homes in small places like Wivelsfield often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, it’s backed by our one-year guarantee.

When it is not the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours in a single home. For a village or hamlet like Wivelsfield, the journey is planned in advance: 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- 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.
Getting ready for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
Advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few photos. Older cottages and farmhouses around Wivelsfield can have timber floors and frames, where water from a failed joint can cause rot 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. You’ll know the price before we begin.

What we are called out for in Wivelsfield
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Keep an eye out for these signs:
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
For new homes near Wivelsfield station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether they’re fully insured
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
- How the colour is chosen

How do I get a quote for new build mastic in Wivelsfield?
Size, access and the old material all affect the cost. Ask us for a quote.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. Once that’s done, or if they will not put it right, we can reseal it properly.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
