About our new build mastic in Heronden
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly instead of bonding to the dust. We work on skirting & floors, plot handovers and kitchens, and people most often call us about new-build shower sealant that has already split and frame joints opening as the plaster dries.
Older homes in small places like Heronden often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We stand behind the work with a 12-month guarantee.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours in a single home, depending on the size of the job. Somewhere as small as Heronden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Mention any sign-in or site rules at work premises

When to call us in Heronden
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
These are the problems we are asked about most:
- Sealant applied over dusty or wet surfaces
- Gaps between new skirting and floors
- Internal frame sealant that has split
- Worktop and upstand sealant coming away
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.

- Is VAT in the price?

New build mastic in Heronden: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Heronden, as everywhere, new build mastic is only as good as the preparation behind it.
Heronden is about 5 miles west of Deal, in Kent. From the centre of Heronden to the outskirts, we cover new build mastic for every kind of property. Our Kent coverage runs to 922 places, Heronden among them. There’s also a page for Chelmsford, roughly 49 miles from Heronden.

Your questions about new build mastic in Heronden
Do you cover smaller places like Heronden?
Yes, Heronden is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Sandwich station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
When is the best time to reseal in a new build?
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 new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Why it’s worth doing now in Heronden
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around Heronden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- The old material and how stubborn it is
- The number and length of the joints
- Which sealant suits the joint
- Any mould that needs treating
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
- Keep pictures and emails about snagging items
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
