New build mastic in Waterham, done properly
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you’re dealing with frame joints opening as the plaster dries and leaking shower tray seals in a new home, we can help, whatever the surface.
In a village or hamlet like Waterham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Waterham questions
Is Waterham within the area you cover?
Yes, Waterham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Waterham?
Yes. Our work covers London and the South East, and Waterham is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us with a short description of the job.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
How we quote for new build mastic
Call for a quick quote. What matters most is:
- Which sealant suits the joint
- How many areas need sealing
- Whether the work is at height
- Any working-time requirements on site
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
Helping us quote
Photos help, but a description is a good start. Please mention:
- A few pictures by email, if you can
- Whether it’s a home or a business
- How we’d reach the joints
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.

Do you need new build mastic in Waterham?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
For new homes near Whitstable station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether all the old sealant comes out first
- Is VAT in the price?
- How much experience the applicator has
- When the joint can take water or movement

What new build mastic looks like in Waterham
Waterham is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Waterham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
