About our new build mastic in Grange Park
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for sealant that never bonded to the surface and smeared, uneven beads picked up at snagging, on plot handovers, bathrooms & en suites and show homes.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Grange Park and beyond.
All our work comes with our one-year guarantee, wherever you are in Greater London.

Why act early in Grange Park
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a flat in Grange Park, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.
Why book with us
- 20+ years of sealant experience
- White, clear, grey or coloured to suit, where the product allows
- Any old sealant cut out fully, not covered over
- ARBOMaster approved applicator
When to call us in Grange Park
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
The problems people generally mention when they call include:
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
For new homes near Grange Park station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- How long to leave it before use
- Whether they seal over old material or remove it
- Whether you can choose the colour
- Which sealant they’ll use, and why
The process
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. The work normally takes anything from a few hours to several days, depending on the number of plots. For a job in Grange Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Joints and finishes in Grange Park homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Grange Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
