Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
About our new build mastic in Wood Green
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you are dealing with new-build shower sealant that has already split and joints pulling apart as timber shrinks, we can help, on windows & doors, skirting & floors and kitchens alike.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Wood Green as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Signs you need new build mastic in Wood Green
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Keep an eye out for these signs:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
As a London address, Wood Green can be tricky for parking: let us know about parking bays, permits or a driveway.

New build mastic in Wood Green: local notes
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
For new homes near Alexandra Palace station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. For a job in Wood Green, 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.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention any tricky access
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in

Advice
Looking after it afterwards
So the new joints stay in good condition:
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.

Why deal with it now?
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few photos and we’ll give you a straight answer. In a flat in Wood Green, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

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.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
