Grahame Park New Build Mastic
Our applicators work in Grahame Park on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

New build mastic for homes and businesses in Grahame Park
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that’s what rushed new-build sealant usually lacks. We work on skirting & floors, bathrooms & en suites and show homes, and common reasons people get in touch are cracked sealant around new window and door frames and cracked caulk along new skirting.
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, in Grahame Park as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

What else we do in Grahame Park
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots. In a London area like Grahame Park, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Advice
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Joints and finishes in Grahame Park homes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Grahame Park can be tricky for parking: let us know about parking bays, permits or a driveway. For new homes near Mill Hill Broadway station, it’s worth checking the sealant early, while snags are still fresh.
