New-build mastic & snagging in Broadwater Farm, Greater London
New-build sealant joints in Broadwater Farm need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

How we handle new build mastic in Broadwater Farm
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you have leaking shower tray seals in a new home and messy sealant that spoils new finishes, we can put it right, whatever the surface.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
All our work comes with our 12-month guarantee, wherever you are in Greater London.

The process
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. In Broadwater Farm, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Do not seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
- Record problems with dated pictures
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
New homes and floors in Broadwater Farm
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Broadwater Farm can be tricky for parking: let us know about parking bays, permits or a driveway. If you’ve bought a new home near Bruce Grove station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Broadwater Farm
Honest limits
New sealant can’t fix everything, and we will tell you before work begins. Sealant won’t put right:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Show homes
- Kitchens
- Windows & doors
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Why act early in Broadwater Farm
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

Your questions about new build mastic in Broadwater Farm
Can you help a landlord with a rental near Bruce Grove station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is parking an issue for new build mastic in Broadwater Farm?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll tell you when we quote.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
