We also work for property managers and facilities teams in Blacklands and across East Sussex. We can quote a run of properties together, and we are fully insured.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How we handle new build mastic in Blacklands
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We’re often asked to deal with second-fix sealing on new plots and cracked sealant around new window and door frames, on kitchens, bathrooms & en suites and show homes.
In and around Blacklands, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Record problems with dated photos
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
- Do not seal over failed sealant yourself
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
Why act early in Blacklands
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Homes in smaller places like Blacklands 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.
A few things move the cost up or down: 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 affects the quote in Blacklands
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- The amount of work
- How easy the joints are to reach
- How many areas need sealing
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
Helping us quote
When you contact us, it’s useful to know:
- If someone has resealed it before
- Whether it’s a home or a business
- What’s wrong with the joints now
- A few pictures by email, if you can
We do not publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or drop us an email.
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 for most snagging lists, longer for a run of plots, including the tidy-up. Parking around Blacklands is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Settlement cracks that need a surveyor
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

When to call us in Blacklands
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
Common reasons people contact us include:
- Shower seals failing in the first year or two
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
If you’ve bought a new home near Ore station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic in Blacklands: local notes
Blacklands is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. 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.
Around Blacklands, as everywhere, new build mastic is only as good as the preparation behind it.

Your questions about new build mastic in Blacklands
Can you help a landlord with a rental near Ore station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Blacklands?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Why does sealant fail so quickly in new builds?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
