New-build mastic & snagging in Hipley, Hampshire
We cover Hipley for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How we handle new build mastic in Hipley
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. Common call-outs are for gaps behind new kitchen upstands and cracked sealant around new window and door frames, across bathrooms & en suites, skirting & floors and show homes.
In a village or hamlet like Hipley, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee.

What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- When we can work, for business premises
- The type of sealant required
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
To make quoting easier, please include:
- Roughly how big the job is
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. For a village or hamlet like Hipley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Mention any tricky access
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant

Common questions in Hipley
Will you come out to Hipley?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Portchester station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
How long does new build mastic take?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer, and we’ll say how long yours will take.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
New homes and floors in Hipley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Hipley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Portchester station, it’s worth checking the sealant early, while snags are still fresh.

Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you are unsure which you have, call 0345 464 0079 or drop us an email with photos. Older cottages and farmhouses around Hipley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
