New build mastic in Wickstreet
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on kitchens, bathrooms & en suites and windows & doors, and people most often call us about cracked caulk along new skirting and sealant applied over dusty or wet surfaces.
Around Wickstreet, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months, in Wickstreet and everywhere else we cover.

Why it’s worth doing now in Wickstreet
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Wickstreet, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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.
Why Wickstreet customers choose us
- Anti-fungal sanitary silicone in wet areas
- Sealant colour chosen to suit
- A choice of colours where the product allows
- We leave the area clean and tidy

What we cannot put right
It helps to know what we cannot do:
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem

What we are called out for in Wickstreet
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Signs it’s time to call us include:
- Joints pulling apart as timber shrinks
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
If you’ve bought a new home near Berwick (Sussex) station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Which colour the sealant will be
- How long to leave it before use
- Who turns up on the day
- Whether all the old sealant comes out first

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a small place like Wickstreet, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out 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.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

New homes and floors in Wickstreet
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Wickstreet questions
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes. We work for landlords and agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Wickstreet within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- The number of rooms or windows
- How easy the joints are to reach
- When we can work, for business premises
- Whether there’s mould to deal with
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To make quoting easier, please include:
- Whether it has been sealed before
- A few pictures by email, if you can
- Whether it’s a home or a business
- How we’d reach the joints
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
