New build mastic in Petworth, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for smeared, uneven beads picked up at snagging and cracks appearing as a new home settles, on kitchens, windows & doors and bathrooms & en suites.
Older homes in small places like Petworth 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, it’s backed by our one-year guarantee.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Petworth, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Let us know about earlier repairs to the joints

Related advice
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Petworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
What you get with us
- Homes, businesses and hotels
- White, clear, grey or coloured to suit, where the product allows
- An ARBOMaster approved applicator
- We agree the colour with you first
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Raise failed sealant with the developer while you are covered
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
When it isn’t the sealant
It helps to know what we cannot do too:
- Cracked trays, tiles or worktops
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Petworth: your questions answered
I let a flat near Pulborough station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Is Petworth within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
What do you need from me for a quote?
Tell us what needs doing and where. If we need more, we’ll ask.
