About our new build mastic in Heaverham
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Common call-outs are for leaking shower tray seals in a new home and gaps behind new kitchen upstands, on bathrooms & en suites, skirting & floors and windows & doors.
Work in a small place like Heaverham just needs the journey and access planning, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Heaverham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- 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.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
After the cure time, these simple habits help:
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Don’t seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Work for landlords, hotels and businesses
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.
Landlords and letting agents in Heaverham can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Joints and finishes in Heaverham homes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Heaverham questions
Do you work for landlords with property near Kemsing station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Heaverham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
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. Poor preparation at handover adds to it.
Are you insured?
Yes, we are fully insured.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
When to call us in Heaverham
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
Any of these means the joints need attention:
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
Around Heaverham, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Who turns up on the day
- What product goes in the joint
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
Why act early in Heaverham
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Older cottages and farmhouses around Heaverham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- Approved under the ARBOMaster scheme
- 20+ years of sealant experience
