New build mastic around South Chailey
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around South Chailey, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Plumpton station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in South Chailey, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on skirting & floors, kitchens and plot handovers, and people most often call us about sealant work across a run of new homes and sealant applied over dusty or wet surfaces.
Work in a small place like South Chailey just needs the journey and access planning, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee, whatever its size.

What else we do in South Chailey
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Aftercare tips
Aftercare is simple:
- Watch for new gaps as the house dries out
- Record problems with dated photos
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with right away
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
- Plumbing faults behind the sealant
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few photos. Where a wall is exposed, as many are in small places like South Chailey, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
To help us quote quickly, please include:
- How we’d reach the joints
- A few photos by email, if you can
- The type of property
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It usually takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as South Chailey, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
