Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
New build mastic in Chilworth, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. If you’re dealing with sealant applied over dusty or wet surfaces and skirting joints opening in the first winter, we can help, whatever the surface.
In a village or hamlet like Chilworth, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Every job is covered by a 12-month guarantee, wherever you are in Southampton.

Do you need new build mastic in Chilworth?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Common reasons people contact us are:
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
Around Chilworth, as everywhere, new build mastic is only as good as the preparation behind it.

Landlords, agents and businesses in Chilworth
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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.
New homes and floors in Chilworth
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.
For new homes near Swaythling station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
To keep the joints looking good and working properly:
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Do not seal over failed sealant yourself
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
