New build mastic in Stone
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. We are often asked to deal with gaps between new skirting and floors and sealant work across a run of new homes, across show homes, skirting & floors and bathrooms & en suites.
Somewhere as small as Stone, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Why act early in Stone
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. In a small place like Stone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- A 12-month guarantee on all work
- Over 20 years’ experience
- Full insurance on every job
- A choice of colours where the product allows

New homes and floors in Stone
Stone is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Do you cover smaller places like Stone?

What guarantee comes with new build mastic in Stone?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Will the old sealant be removed?

Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Hampshire.

Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. Somewhere like Stone needs a little journey planning: let us know about lanes, gates and parking. 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.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

Related advice
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Do you need new build mastic in Stone?
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
If you can see any of these, it’s time to have the joints looked at:
- Internal frame sealant that has split
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
Whether the job is in Stone itself or nearby, the right material for each joint matters as much as a neat finish.

Helping us quote
To help us quote quickly, let us know:
- How we’d reach the joints
- The problem you’ve noticed
- Whether it has been sealed before
- Whether it’s a home or a business
We quote each job on its own. Simply phone 0345 464 0079 or email us and describe the job.
How to look after the new joints
To keep the joints looking good and working properly:
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
