Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Bobbingworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

New build mastic in Bobbingworth
Across Bobbingworth, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Typical jobs include new-build shower sealant that has already split and cracks appearing as a new home settles, on bathrooms & en suites, skirting & floors and windows & doors.
Older homes in small places like Bobbingworth often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What sealant work cannot fix
Before booking, it’s worth knowing the limits:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem

What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots from start to finish. Somewhere as small as Bobbingworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Common questions in Bobbingworth
What guarantee comes with new build mastic in Bobbingworth?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Bobbingworth?
Yes, Bobbingworth is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
What new build mastic looks like in Bobbingworth

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with straight away
- Ventilate bathrooms well, especially in the first year
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
