About our new build mastic in Broadstairs
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. Typical jobs include messy sealant that spoils new finishes and internal frame sealant that has split, across plot handovers, kitchens and show homes.
In a town like Broadstairs, skirting and floor joints open up as homes settle and floors move with the seasons. A flexible sealant, rather than rigid filler, keeps those joints closed.
There’s a 12-month guarantee on every job.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Resist patching a failed seal with a tube from the DIY shop
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Broadstairs and across Kent. We can quote a run of properties together, and we’re fully insured.
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 that we can handle for you.
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. For a job in Broadstairs, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

What else we do in Broadstairs
New homes and floors in Broadstairs
Broadstairs is within about 1 mile 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Broadstairs station, it’s worth checking the sealant early, while snags are still fresh. In and around Broadstairs, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Broadstairs
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Black mould and gaps in sealant do not fix themselves, and in a busy household in Broadstairs they spread with every shower and every downpour. Now is the easy time to put it right.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Different surfaces, different methods
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A tray or bath that is not properly supported, until it’s fixed
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Kitchens
- Bathrooms & en suites
- Show homes
- Windows & doors
- Skirting & floors
- Plot handovers
Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
