Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
New build mastic in Deane, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Typical jobs include smeared, uneven beads picked up at snagging and beads laid onto grit and dust from the build, across bathrooms & en suites, skirting & floors and kitchens.
In a village or hamlet like Deane, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in Deane
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry first.
These are the problems we are asked about most:
- Sealant applied over dusty or wet surfaces
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
Around Deane, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
- Follow the cure time we give you
Watch the joints as the house settles. Small gaps can appear as the house dries.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:

- Whether there’s mould to deal with
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

How it works
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work usually takes a few hours in a single home. In a small place like Deane, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Why it’s worth doing now in Deane
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Deane can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
Why book with us
- A 12-month guarantee on all work
- Tidy, careful work
- More than 20 years in sealant work
- Fully insured
Your questions about new build mastic in Deane
Is Deane in your area for new build mastic?
Yes, Deane is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is Deane within the area you cover?
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.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
Should I wait before resealing?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
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.

What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
