How we handle new build mastic in Boxgrove
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. If you are dealing with kitchen sealant that has pulled off the wall and internal frame sealant that has split, we can put it right, whatever the surface.
For a small place like Boxgrove, the journey and access are planned in advance, and the work itself is the same as on any site.
Whatever the size of the job, you get the same 12-month guarantee in Boxgrove and across West Sussex.

Your questions about new build mastic in Boxgrove
Can you help a landlord with a rental near Chichester station?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Boxgrove within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots. We will confirm how long when we quote.
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.
Do you need new build mastic in Boxgrove?
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
The problems people usually mention when they call are:
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
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.

What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there.
Why act early in Boxgrove
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Boxgrove, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- White, clear, grey or another colour, product permitting

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
When you contact us, it’s useful to know:
- The problem you’ve noticed
- If someone has resealed it before
- Photos by email, if that’s easy
- The rough size of the job
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or send us an email and describe the job and send pictures if you have them.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours in a single home. In a small place like Boxgrove, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- 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.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

For anyone letting property in or around Boxgrove, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
