New build mastic for homes and businesses in Chandler's Ford
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on skirting & floors, windows & doors and kitchens, and common reasons people get in touch are plot mastic for developers ahead of handover and joints pulling apart as timber shrinks.
Towns like Chandler's Ford have older streets and newer estates side by side. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.
Each job carries a 12-month guarantee, large or small.

FAQs for Chandler's Ford
I let a flat near Chandlers Ford station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is new build mastic in Chandler's Ford guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
What should I tell you?
Let us know what needs doing and where. We will ask anything else we need to know.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep water off fresh sealant until it has cured
- Don’t wait for the house to settle if water is getting through
- Use the extractor fan every time you shower
- Keep photos and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. 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.
What affects the quote in Chandler's Ford
Call for a quick quote. The main things that affect it are:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- The type of property
- Any access issues, like height or stairs
- A few photos by email, if you can

Signs you need new build mastic in Chandler's Ford
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Common reasons people contact us include:
- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
For new homes near Chandlers Ford station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- Which colour the sealant will be
- Are they insured?
Landlord and commercial work in Chandler's Ford
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
How it works
The work is kept neat and contained to the joints we’re treating. The job generally takes a few hours in a single home, and we explain the cure time before we leave. For a job in Chandler's Ford, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Clear items away from the joints we are working on
