Surface by surface

Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered as agreed.
New build mastic in Chavey Down, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. Typical jobs include gaps behind new kitchen upstands and cracked caulk along new skirting, across show homes, plot handovers and windows & doors.
Older homes in small places like Chavey Down often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Landlords, agents and businesses in Chavey Down
For anyone letting property in or around Chavey Down, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Where a wall is exposed, as many are in small places like Chavey Down, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- One-year guarantee on every job
- Neat joints and a tidy finish
- Quality sealants from Arbo and Everbuild
- Domestic, commercial and hotel work

When to call us in Chavey Down
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 can tear.
Signs it’s time to call us include:
- Beads laid onto grit and dust from the build
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
For new homes near Martins Heron station, it’s worth checking the sealant early, while snags are still fresh.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Do the sealants smell?

What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room before we begin.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.

How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
