What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Goodnestone 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 go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Move anything stored near the joints

New build mastic in Goodnestone, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on kitchens, windows & doors and show homes, and people most often call us about cracked sealant around new window and door frames and untidy sealant flagged on a snagging list.
In a village or hamlet like Goodnestone, 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Landlords, agents and businesses in Goodnestone
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Where a wall is exposed, as many are in small places like Goodnestone, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before we start.

Common problems we fix in Goodnestone
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Common reasons people contact us include:
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
If you’ve bought a new home near Faversham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Goodnestone questions

Yes, Goodnestone is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. If it is not resolved, we’ll cut it out and reseal it.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
New build mastic around Goodnestone
Goodnestone is close to 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Goodnestone, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Put sealant faults on your snagging list early
- Don’t seal over failed sealant yourself
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
