New build mastic for homes and businesses in Kidbrooke
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. If you have second-fix sealing on new plots and gaps behind new kitchen upstands, we can put it right.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement.
All our work comes with our 12-month guarantee, wherever you are in Greater London.

Kidbrooke: your questions answered
I let a flat near Kidbrooke station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is parking an issue for new build mastic in Kidbrooke?
Parking in Kidbrooke, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Cracked trays, tiles or worktops
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.
Joints and surfaces we work on
- Windows & doors
- Plot handovers
- Kitchens
- Skirting & floors
- Bathrooms & en suites
- Show homes
Why deal with it now?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Kidbrooke, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
Why book with us
- A 12-month guarantee on all work
- You choose the colour before work begins
- More than 20 years in sealant work
- Full insurance on every job

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we’re called out for in Kidbrooke
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Internal frame sealant that has split
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
As a London address, Kidbrooke can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a job in Kidbrooke, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
How to get a quote
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
