New build mastic for homes and businesses in Old Wolverton
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly. We work on plot handovers, kitchens and windows & doors, and the jobs we see most are leaking shower tray seals in a new home and beads laid onto grit and dust from the build.
In and around Old Wolverton, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
Our work is backed for twelve months.

What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We’ll plan around viewing times.
Landlords, agents and businesses in Old Wolverton
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Homes in smaller places like Old Wolverton 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.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Common problems we fix in Old Wolverton
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Most people get in touch when they notice one of these:
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Wolverton station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. In a smaller place like Old Wolverton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about any water getting in
- Clear the area around the work
- Keep children and pets away from the work area

How to look after the new joints
So the new joints stay in good condition:
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
