New build mastic for homes and businesses in Thorley
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We are often asked to deal with leaking shower tray seals in a new home and gaps opening as the house dries out and settles, across skirting & floors, plot handovers and show homes.
For a small place like Thorley, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
All our work is covered by our 12-month guarantee.

Common problems we fix in Thorley
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
People generally contact us after spotting one of these:
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
Around Thorley, as everywhere, new build mastic is only as good as the preparation behind it.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Older cottages and farmhouses around Thorley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why Thorley customers choose us
- We’re fully insured
- White, clear, grey or another colour, product permitting
- Anti-fungal sanitary silicone in wet areas
- We never seal over old sealant
See our cost guide or customer reviews.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
When it is not the sealant
Sealant is not the answer to every problem, and we will tell you before any work starts. It will not solve:
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Show homes
- Bathrooms & en suites
- Windows & doors
- Kitchens
- Skirting & floors
- Plot handovers
Thorley questions
Is Thorley in your area for new build mastic?

Is Thorley within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. Once that is done, or if they won’t put it right, we can reseal it properly.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across the Isle of Wight.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
New build mastic in Thorley: local notes
Thorley is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. 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.
For new homes near Lymington Pier station, it’s worth checking the sealant early, while snags are still fresh.
Thorley is about 5 miles south-east of Lymington, in the Isle of Wight. Our applicators cover new build mastic for homes and businesses in Thorley and the surrounding area, as part of our work across the Isle of Wight. We cover 125 towns and villages across the Isle of Wight, from the larger towns to small villages. We also work in Southampton, around 16 miles away.
All of PO41 is covered for new build mastic. Close by, we work in Thorley Street (1 mile east), Wellow (1 mile south-east), Ningwood (2 miles east), Shalcombe (2 miles south-east) and Newbridge (2 miles east).

If you are somewhere remote, the job takes a little more planning, so mention it when you ask for a quote.

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a village or hamlet like Thorley, 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 look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
What affects the quote in Thorley
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- The old material and how stubborn it is
- How many areas need sealing
- The size of the job
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Photos by email, if that’s easy
