New build mastic for homes and businesses in Fullwell Cross
Across Fullwell Cross, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you are dealing with gaps between new skirting and floors and leaking shower tray seals in a new home, we can put it right, whatever the surface. As specialist sealant applicators, we take on new build mastic and every other kind of sealant job in Fullwell Cross.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we’re called out for in Fullwell Cross
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry first.
Signs it’s time to call us include:
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Cracked caulk along new skirting
Fullwell Cross is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Which colour the sealant will be
- Whether they’re fully insured
- Is VAT in the price?
- How the joint is cleaned and prepared
Why act early in Fullwell Cross
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
Why Fullwell Cross customers choose us
- An ARBOMaster approved applicator
- A choice of colours where the product allows
- You choose the colour before work begins
- A 12-month guarantee on all work

When it is not the sealant
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- A tray or bath that is not properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
Not sure which it is? You can phone 07833 053749 or email us and we will tell you honestly.
What we seal
