Upper Harbledown New Build Mastic
We cover Upper Harbledown for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Upper Harbledown, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Why book with us
- Tidy, careful work
- Domestic, commercial and hotel work
- Colour agreed with you before any work starts
- White, clear, grey or coloured to suit, where the product allows
How we handle new build mastic in Upper Harbledown
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on windows & doors, bathrooms & en suites and show homes, and common reasons people get in touch are joints pulling apart as timber shrinks and sealant that never bonded to the surface.
For a small place like Upper Harbledown, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Every job comes with our one-year guarantee, wherever you are in Kent.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
When to call us in Upper Harbledown
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
The most common problems we see are:
- New-build shower sealant that has already split
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
For new homes near Canterbury West station, it’s worth checking the sealant early, while snags are still fresh.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Upper Harbledown, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- 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.
Before we arrive
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Related advice
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
