Surface by surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered to the agreed spec.

For builders and developers, we work through plots to the schedule you give us.

If you’re dealing with shower seals failing in the first year or two and cracks appearing as a new home settles, we can put it right, whatever the surface.
For a small place like Greatham, the journey and access are planned in advance, and the work itself is the same as on any site.

What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- The type of sealant required
- Access and height
- Mould in or behind the old joints
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- The rough size of the job
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or drop us an email.
When to call us in Greatham
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
These are the problems we are asked about most:
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
- Messy sealant that spoils new finishes
Around Greatham, as everywhere, new build mastic is only as good as the preparation behind it.

Aftercare tips
To keep the joints looking good and working properly:
- Avoid scourers and strong chemicals on sealant
- Record problems with dated photos
- Follow the cure time we give you
- Act quickly if a seal starts to leak
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
FAQs for Greatham
Is Greatham in your area for new build mastic?
Yes, Greatham is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Will you come out to Greatham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

How it works

Everything for the job comes with us, so a second trip is avoided where possible.
