Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.
About our new build mastic in High Park Corner
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. If you have leaking shower tray seals in a new home and kitchen sealant that has pulled off the wall, we can help, whatever the surface.
Older homes in small places like High Park Corner often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Can you quote for more than one area?
Yes. Just list everything you need and we will quote it together.
Is it normal for sealant to crack in a new home?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.

What new build mastic looks like in High Park Corner
High Park Corner is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
In and around High Park Corner, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ventilate bathrooms well, especially in the first year
- Do not wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
- Don’t seal over failed sealant yourself
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why it’s worth doing now in High Park Corner
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Where a wall is exposed, as many are in small places like High Park Corner, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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. Your quote takes all of that into account.
Why us?
- Colour picked to suit the job
- We leave the area clean and tidy
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over

How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. Somewhere as small as High Park Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- 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
- Move anything stored near the joints
- Mention any tricky access
- Mention any parking rules near the property
Getting a quote
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.

Common problems we fix in High Park Corner
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Common reasons people contact us include:
- Second-fix sealing on new plots
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
For new homes near Wivenhoe station, it’s worth checking the sealant early, while snags are still fresh.
