New-build mastic & snagging in Sandy Balls, Hampshire
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Sandy Balls and across Hampshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic in Sandy Balls
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you have skirting joints opening in the first winter and second-fix sealing on new plots, we can help, on bathrooms & en suites, skirting & floors and plot handovers alike.
Somewhere as small as Sandy Balls, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sandy Balls and across Hampshire.

What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
When to call us in Sandy Balls
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
In and around Sandy Balls, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Sandy Balls, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. Somewhere as small as Sandy Balls, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- 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
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Clear the area around the work

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For jobs in and around Sandy Balls, choosing the right material for each joint is as important as a tidy finish.
