New build mastic in Harbledown
Across Harbledown, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you have leaking shower tray seals in a new home and second-fix sealing on new plots, we can put it right.
In a village or hamlet like Harbledown, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Record problems with dated pictures
- Keep water off fresh sealant until it has cured
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Settlement cracks that need a surveyor
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Why it’s worth doing now in Harbledown
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Where a wall is exposed, as many are in small places like Harbledown, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
What you get with us
- Any old sealant cut out fully, not covered over
- Over 20 years’ experience
- You choose the colour before work begins
- Quality sealants from Arbo and Everbuild

When to call us in Harbledown
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Most people get in touch after spotting something like this:
- Cracked caulk along new skirting
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
- 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.
Questions to ask before you book
- How the surfaces are prepared before sealing
- How long the guarantee is
- What the quote includes, VAT included or not
- When the joint can take water or movement

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Harbledown and across Kent. We can quote a run of properties together, and we are fully insured.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Harbledown, access is generally the main thing to plan. 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
