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.
If you’ve bought a new home near Chichester station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Westerton, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with messy sealant that spoils new finishes and frame joints opening as the plaster dries, on windows & doors, plot handovers and bathrooms & en suites.
Older homes in small places like Westerton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, you get the same one-year guarantee.

Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- The product the joint needs
- How easy the joints are to reach
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
When you call or email, it’s useful to know:
- The type of property
- The address or postcode of the job
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
If you manage several properties in or around Westerton, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Leave it or put it right?
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. In a small place like Westerton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Signs you need new build mastic in Westerton
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
- Kitchen sealant that has pulled off the wall
Around Westerton, as everywhere, new build mastic is only as good as the preparation behind it.

Common questions in Westerton
Do you work for landlords with property near Chichester station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do new build mastic in Westerton?

Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
How much does new build mastic cost in Westerton?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Westerton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- 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
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
