New build mastic in West Chiltington
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. Both get the same care over preparation. We work on kitchens, bathrooms & en suites and skirting & floors, and people most often call us about beads laid onto grit and dust from the build and untidy sealant flagged on a snagging list.
Around West Chiltington, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee.

West Chiltington: your questions answered
I let a flat near Pulborough station. Can you help?

Is West Chiltington in your area for new build mastic?

What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we’re fully insured.
Can I send you my snagging list?
Yes. Send the list and a few photos of the sealant items and we’ll give you a quote. We’ll flag anything that needs another trade.
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.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: 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 West Chiltington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours in a single home, including the tidy-up. For a village or hamlet like West Chiltington, 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 agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules

When to call us in West Chiltington
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
In and around West Chiltington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What affects the quote in West Chiltington
Every job gets its own quote. This is what makes a difference:
- Any working-time requirements on site
- The product the joint needs
- The number of rooms or windows
- The number and length of the joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
To make quoting easier, please include:
- The address or postcode of the job
- Roughly how big the job is
- Whether it’s a home or a business
- Photos by email, if that is easy
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Record problems with dated photos
- Wait for the cure time before using a resealed shower
- Act quickly if a seal starts to leak
- Put sealant faults on your snagging list early
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
