New build mastic in Hollingbury, done properly
We work in new homes and on new-build sites across Hollingbury. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with cracked caulk along new skirting and messy sealant that spoils new finishes, we can help, whatever the surface.
Homes around Hollingbury range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Your questions about new build mastic in Hollingbury
Is Hollingbury within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Moulsecoomb station?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
How long does new build mastic take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer, and we will say how long yours will take.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Hollingbury.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
How do I get a quote for new build mastic in Hollingbury?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. A visit to Hollingbury is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Why it’s worth doing now in Hollingbury
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. Homes in smaller places like Hollingbury can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
What you get with us
- Quality sealants from Arbo and Everbuild
- Colour agreed with you before work begins
- White, clear, grey or coloured to suit, where the product allows
- We leave the area clean and tidy

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

What affects the quote in Hollingbury
We quote each job individually. This is what makes a difference:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- The type of sealant required
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How we’d reach the joints
- The problem you’ve noticed
- Whether it has been sealed before
- A few photos by email, if you can
If you’re in Hollingbury and need new build mastic, call 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before work begins.
New build mastic around Hollingbury
Hollingbury is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Hollingbury, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Moulsecoomb station, it’s worth checking the sealant early, while snags are still fresh.

- Plot handovers

Looking after it afterwards
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
- Record problems with dated photos
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
