New build mastic in Billingshurst
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you are dealing with gaps opening as the house dries out and settles and beads laid onto grit and dust from the build, we can help, on plot handovers, windows & doors and kitchens alike.
If you’ve bought a new home in or near Billingshurst, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours in a single home for a typical job. For a job in Billingshurst, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Why deal with it now?
The builder is normally 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. Homes in smaller places like Billingshurst can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Arbo and Everbuild products
- White, clear, grey or another colour, product permitting
- Tidy, careful work
- A sealant colour to suit the surroundings

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
Joints and surfaces we work on
- Kitchens
- Plot handovers
- Skirting & floors
- Bathrooms & en suites

When to call us in Billingshurst
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
These are the problems we’re asked about most:
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
- Skirting joints opening in the first winter
In and around Billingshurst, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Do not wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
