How we handle new build mastic in Densole
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. We work on windows & doors, kitchens and plot handovers, and the jobs we see most are cracked caulk along new skirting and beads laid onto grit and dust from the build.
Older homes in small places like Densole often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a one-year guarantee, the same in Densole as everywhere else we work.

How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered as agreed.
Your questions about new build mastic in Densole
Is Densole within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in Densole?
Yes. Our work covers London and the South East, and Densole is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
My new home is still under warranty. Should I contact you?
Start with the builder if you are in the snagging or warranty period. If it is not resolved, we can reseal it properly.
How do I get a quote for new build mastic in Densole?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us with a short description of the job.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.

What we can’t put right
We will always be straight with you, so here’s what new sealant won’t do:
- Structural cracks in walls or ceilings
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
Where we work in Densole
- Windows & doors
- Show homes
- Skirting & floors
- Plot handovers
- Kitchens
- Bathrooms & en suites
Looking after it afterwards
Looking after new joints is easy:
- Wait for the cure time before using a resealed shower
- Do not wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Signs you need new build mastic in Densole
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
Around Densole, as everywhere, new build mastic is only as good as the preparation behind it.
