New build mastic in Herongate, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you have plot mastic for developers ahead of handover and sealant applied over dusty or wet surfaces, we can put it right, on show homes, windows & doors and bathrooms & en suites alike.
Somewhere as small as Herongate, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes a few hours in a single home. Somewhere like Herongate needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, 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.
- Each bead is tooled and the cure times explained.
How to prepare

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What affects the cost of new build mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- When we can work, for business premises
- The amount of work
- Which sealant suits the joint
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
When you contact us, it’s useful to know:
- A few photos by email, if you can
- Where the job is, and your postcode
- If someone has resealed it before
- How many joints, rooms or windows are involved
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.
Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Herongate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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.

Do you need new build mastic in Herongate?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Look out for any of the following:
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Worktop and upstand sealant coming away
If you’ve bought a new home near West Horndon station, the sealant around baths, showers and frames is worth checking in the first year or two.

How do I get a quote for new build mastic in Herongate?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
Why has my new-build shower seal failed already?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
