New build mastic in Knockholt Pound, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant generally lacks. We are often asked to deal with new-build shower sealant that has already split and cracked sealant around new window and door frames, on skirting & floors, plot handovers and kitchens.
Work in a small place like Knockholt Pound just needs the journey and access planning, and once on site, the job is the same as anywhere.
Every job comes with a one-year guarantee.

Common problems we fix in Knockholt Pound
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Common reasons people contact us are:
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
In and around Knockholt Pound, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Plot handovers
Developers can send the plot schedule and specification and we will quote. Sealant work across the plot is covered.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
What happens on the day
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. Somewhere as small as Knockholt Pound, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- On commercial sites, let us know about site rules

What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Knockholt Pound, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
