New build mastic in Radwinter
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 show homes, kitchens and bathrooms & en suites, and the jobs we see most are messy sealant that spoils new finishes and second-fix sealing on new plots.
Somewhere as small as Radwinter, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same 12-month guarantee.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours in a single home. For a village or hamlet like Radwinter, 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Access and height
- How many areas need sealing
- The type of sealant required
- When we can work, for business premises
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
Helping us quote
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- What’s wrong with the joints now
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or drop us an email.
How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
What new build mastic looks like in Radwinter
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.
For jobs in and around Radwinter, choosing the right material for each joint is as important as a tidy finish. In and around Radwinter, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Cracking that points to a structural problem
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal

My new home is still under warranty. Should I contact you?

If you’ve already had a go yourself, that’s fine. We cut it out and start again.
