How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home. For a village or hamlet like Bonchurch, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit

Do you need new build mastic in Bonchurch?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening as the house dries out and settles
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Shower seals failing in the first year or two
If you’ve bought a new home near Shanklin station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Whether the sealant suits the joint
- What happens if they find a problem under the old sealant
- The length of the guarantee
- How much experience the applicator has
Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

Why it’s worth doing now in Bonchurch
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Bonchurch can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Joints and finishes in Bonchurch homes
Bonchurch is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
In and around Bonchurch, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Follow the cure time we give you
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.

Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
