New Build Mastic in Hillyfields
Our applicators work in Hillyfields on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
How we handle new build mastic in Hillyfields
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. If you are dealing with beads laid onto grit and dust from the build and untidy sealant flagged on a snagging list, we can help, on skirting & floors, windows & doors and plot handovers alike.
In smaller places like Hillyfields, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
All our work is covered by our 12-month guarantee, wherever you are in Southampton.

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Hillyfields questions
Do you cover Hillyfields for new build mastic?
Yes. We work across London and the South East, and Hillyfields is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Redbridge station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours in a single home. We will give you a better idea when we quote.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Homes in smaller places like Hillyfields can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, 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.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What else we do in Hillyfields
What affects the quote in Hillyfields
We do not publish a price list, because jobs vary so much. What we look at:
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- The size of the job
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.
Asking for a quote
To help us quote quickly, let us know:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Any previous sealing or DIY work
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
The process
Before we leave, we go over the finished joints with you. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. A visit to Hillyfields 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.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Do you need new build mastic in Hillyfields?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
People normally contact us when they notice one of these:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
Around Hillyfields, as everywhere, new build mastic is only as good as the preparation behind it.

Joints and finishes in Hillyfields homes
Hillyfields is close to 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Redbridge station, it’s worth checking the sealant early, while snags are still fresh.
