About our new build mastic in Goddington
We work in new homes and on new-build sites across Goddington. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Common call-outs are for cracked sealant around new window and door frames and cracked caulk along new skirting, across skirting & floors, show homes and bathrooms & en suites.
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.
Our work is backed for twelve months, in Goddington and everywhere else we cover.

What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal

What new build mastic looks like in Goddington
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Goddington is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Common questions in Goddington
Can you help a landlord with a rental near Chelsfield station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is parking an issue for new build mastic in Goddington?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots. In a London area like Goddington, the main things to plan are parking and access: 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.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints

Do you need new build mastic in Goddington?
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Keep an eye out for any of the following:
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
For new homes near Chelsfield station, it’s worth checking the sealant early, while snags are still fresh.
