New Build Mastic in Yarbridge
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Yarbridge and across the Isle of Wight. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Beads laid onto grit and dust from the build
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Record problems with dated pictures
- Follow the cure time we give you
- Do not seal over failed sealant yourself
- Get a leaking seal dealt with right away
Watch the joints as the house settles. Small gaps can appear as the house dries.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
New build mastic in Yarbridge, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Typical jobs include joints pulling apart as timber shrinks and plot mastic for developers ahead of handover, on skirting & floors, show homes and plot handovers.
In a village or hamlet like Yarbridge, 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.
Big or small, you get the same 12-month guarantee.

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Brading station, it’s worth checking the sealant early, while snags are still fresh.

When to call us in Yarbridge
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry.
Most people get in touch after spotting something like this:
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
Around Yarbridge, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- How long to leave it before use
- What happens if they find a problem under the old sealant
- What product goes in the joint
- How the joint is cleaned and prepared
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Yarbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Where is Mr Mastic based?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
