What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Graveney needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height

How we handle new build mastic in Graveney
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. Typical jobs include sealant applied over dusty or wet surfaces and cracked sealant around new window and door frames, on show homes, kitchens and bathrooms & en suites.
Work in a small place like Graveney just needs the journey and access planning, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Graveney
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
In and around Graveney, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking

Graveney questions
Do you cover Graveney for new build mastic?
Yes. Our work covers London and the South East, and Graveney is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is Graveney within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we’ll quote. We’ll flag anything that needs another trade.
Is it normal for sealant to crack in a new home?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.
What does new build mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep photos and emails about snagging items
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
