New build mastic in Shiplake Cross
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We work on windows & doors, plot handovers and skirting & floors, and common reasons people get in touch are leaking shower tray seals in a new home and joints pulling apart as timber shrinks.
In a village or hamlet like Shiplake Cross, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Watch for new gaps as the house dries out
- Get a leaking seal dealt with straight away
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Small faults turn into leaks if left.

Other services in Shiplake Cross
Different surfaces, different methods
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Shiplake Cross, older homes often have timber in their 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, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Signs you need new build mastic in Shiplake Cross
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
For new homes near Shiplake station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- What happens if the job turns out different
- Whether VAT is included
- How long the guarantee is
- How the surfaces are prepared before sealing
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Shiplake Cross?

Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
