How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on.

Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.

Advice
How we handle new build mastic in West Itchenor
We work in new homes and on new-build sites across West Itchenor. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. If you have internal frame sealant that has split and messy sealant that spoils new finishes, we can put it right.
Older homes in small places like West Itchenor often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Why act early in West Itchenor
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few pictures and we’ll give you a straight answer. Where a wall is exposed, as many are in small places like West Itchenor, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why book with us
- A sealant colour to suit the surroundings
- We agree the colour with you first
- Any old sealant cut out fully, not covered over
- 12-month guarantee on every job

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 West Itchenor, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Record problems with dated photos
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
What we are called out for in West Itchenor
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
For new homes near Bosham station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- Is the old sealant removed completely?
- How long to leave it before use
- What product goes in the joint
- Which colour the sealant will be
