What new build mastic looks like in Crossbush
Crossbush is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Crossbush, as everywhere, new build mastic is only as good as the preparation behind it.

How we handle new build mastic in Crossbush
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. If you’re dealing with gaps between new skirting and floors and sealant that never bonded to the surface, we can help, whatever the surface.
Work in a small place like Crossbush just needs the journey and access planning, and once on site, the job is the same as anywhere.
Whatever the size of the job, you get the same 12-month guarantee.

For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
What affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- Working hours on commercial sites
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The rough size of the job
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
Need a quote? Please call 0345 464 0079 or email us and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Keeping the joints in good condition
Aftercare is simple:
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Keep photos and emails about snagging items
- Follow the cure time we give you
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

What else we do in Crossbush
Signs you need new build mastic in Crossbush
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracked sealant shows up.
It’s worth asking for a quote if you see:
- Internal frame sealant that has split
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
If you’ve bought a new home near Arundel station, the sealant around baths, showers and frames is worth checking in the first year or two.

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours in a single home. In a small place like Crossbush, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Mention any tricky access

Advice
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Where a wall is exposed, as many are in small places like Crossbush, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, 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.

How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
