About our new build mastic in Southington
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you have plot mastic for developers ahead of handover and smeared, uneven beads picked up at snagging, we can help, on plot handovers, skirting & floors and bathrooms & en suites alike.
Older homes in small places like Southington often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours in a single home. Somewhere like Southington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

Common problems we fix in Southington
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Look out for these signs:
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
- Gaps behind new kitchen upstands
For new homes near Overton station, it’s worth checking the sealant early, while snags are still fresh.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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. Around Southington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What the job involves on each surface
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We’ll plan around viewing times.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
