How we handle new build mastic in Gravel Castle
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Common call-outs are for cracked caulk along new skirting and worktop and upstand sealant coming away, on windows & doors, plot handovers and bathrooms & en suites.
Work in a small place like Gravel Castle just needs the journey and access planning, and the work itself is the same as on any site.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Clean sealant with mild detergent, not abrasives
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Avoid running a DIY bead over the old one
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we are called out for in Gravel Castle
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- Internal frame sealant that has split
- Cracked caulk along new skirting
- New-build shower sealant that has already split
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Snowdown station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Is VAT in the price?
- What product goes in the joint
- The length of the guarantee
- Who turns up on the day
Why act early in Gravel Castle
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Older cottages and farmhouses around Gravel Castle can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Old sealant always removed completely
- Colour agreed with you before any work starts
- 12-month guarantee on every job

When it is not the sealant
Before you book, it’s worth knowing the limits:
- Damaged fittings that need replacing
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
