When to call us in Swanley Village
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Most people get in touch after spotting one of these:
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
If you’ve bought a new home near Swanley station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Swanley Village
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have kitchen sealant that has pulled off the wall and cracks appearing as a new home settles, we can put it right, on bathrooms & en suites, kitchens and skirting & floors alike.
In a village or hamlet like Swanley Village, 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.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
- Broken tiles or a split tray

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Raise failed sealant with the developer while you are covered
- Keep pictures and emails about snagging items
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
Different surfaces, different methods
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.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

Tidy work is part of the job. Nearby surfaces are protected.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you work for developers?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
