Do you need new build mastic in Walton?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Look out for any of the following:
- Skirting joints opening in the first winter
- Shower seals failing in the first year or two
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
If you’ve bought a new home near Bow Brickhill station, the sealant around baths, showers and frames is worth checking in the first year or two.

About our new build mastic in Walton
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for frame joints opening as the plaster dries and kitchen sealant that has pulled off the wall, across show homes, kitchens and windows & doors.
Where new homes go up in smaller places like Walton, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Landlord and commercial work in Walton
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Why it’s worth doing now in Walton
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. Homes in smaller places like Walton can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
