New build mastic in Denstroude, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on kitchens, bathrooms & en suites and windows & doors, and people most often call us about skirting joints opening in the first winter and beads laid onto grit and dust from the build.
For a small place like Denstroude, the journey and access are planned in advance, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Denstroude
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Denstroude, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Joints and finishes in Denstroude homes
Denstroude is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
For new homes near Whitstable station, it’s worth checking the sealant early, while snags are still fresh. In and around Denstroude, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Denstroude, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Before we arrive
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can

Related advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The old material and how stubborn it is
- How much there is to do
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
