New homes and floors in Wentworth
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Wentworth, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Longcross station, it’s worth checking the sealant early, while snags are still fresh.

How we handle new build mastic in Wentworth
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We work on show homes, skirting & floors and windows & doors, and people most often call us about skirting joints opening in the first winter and cracks appearing as a new home settles.
For a small place like Wentworth, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

What the job involves on each surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Somewhere like Wentworth needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- 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.
- We check every joint and tell you how long each needs to cure.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Wentworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope and we will quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Don’t wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
- Look at the sealant regularly in the first couple of years
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
