New build mastic in Ightham
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you have sealant that never bonded to the surface and gaps behind new kitchen upstands, we can help, on kitchens, bathrooms & en suites and windows & doors alike.
Work in a small place like Ightham just needs the journey and access planning, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

What we do, step by step
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours in a single home, including the tidy-up. For a village or hamlet like Ightham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip 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.
- Surfaces are cleaned of building dust and primed where needed.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Ightham: your questions answered
Will you come out to Ightham?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Ightham for new build mastic?
Yes. Our work covers London and the South East, and Ightham is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Ightham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.

DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Plumbing faults behind the sealant
- Settlement cracks that need a surveyor
- Broken tiles or a split tray
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

How to look after the new joints
Looking after new joints is easy:
- Do not wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
