New-build mastic & snagging in Shawford, Hampshire
New-build sealant joints in Shawford need attention? We cut out the old, prepare the joints and apply the right sealant.
- Second-fix sealing on new plots
- Kitchen sealant that has pulled off the wall
- Shower seals failing in the first year or two
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with

How we handle new build mastic in Shawford
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. Common call-outs are for beads laid onto grit and dust from the build and cracks appearing as a new home settles, on kitchens, plot handovers and show homes.
Older homes in small places like Shawford often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Housing providers, facilities teams and property managers book us too in Shawford and across Hampshire. We can quote a run of properties together, and we are fully insured.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What happens on the day
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Shawford 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.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know about stairs, lifts or work at height
- Clear the area around the work
- Keep children and pets away from the work area

- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
In and around Shawford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
