Why it’s worth doing now in Westdene
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In an older home around Westdene, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How we handle new build mastic in Westdene
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on windows & doors, kitchens and plot handovers, and common reasons people get in touch are gaps behind new kitchen upstands and leaking shower tray seals in a new home.
In smaller places like Westdene, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Honest limits
A few problems are outside what sealant work can do:
- Deciding who is responsible under a builder’s warranty
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracking that points to a structural problem

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Get a leaking seal dealt with straight away
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors.
New homes and floors in Westdene
Westdene is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

What sealant do you use?

Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Parking around Westdene is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
