Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

New build mastic in Broadwater: local notes
Broadwater is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Broadwater, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Worthing station, the sealant around baths, showers and frames is worth checking in the first year or two.

Do I have to be there?

Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Skirting & floors
- Windows & doors
- Kitchens
- Show homes
- Bathrooms & en suites

What else we do in Broadwater
What we do, step by step
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours in a single home in most cases. For a job in Broadwater, 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

Related advice
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Homes in smaller places like Broadwater can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What you get with us
- Homes, businesses and hotels
- 20+ years of sealant experience

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
