- Second-fix sealing on new plots
New build mastic in Freshwater
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with untidy sealant flagged on a snagging list and gaps behind new kitchen upstands, across bathrooms & en suites, kitchens and plot handovers.
If you’ve bought a new home in or near Freshwater, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Whatever the size of the job, it’s backed by our one-year guarantee in Freshwater and across the Isle of Wight.

Why act early in Freshwater
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Freshwater, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Questions from Freshwater
Will you come out to Freshwater?
Yes. Freshwater is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on new build mastic in Freshwater?
All our work, in Freshwater and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Do you have insurance?
Yes, we’re fully insured.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.

New build mastic around Freshwater
Freshwater is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For jobs in and around Freshwater, choosing the right material for each joint is as important as a tidy finish.
Freshwater is about 5 miles south of Lymington, in the Isle of Wight. Jobs in Freshwater get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Freshwater is one of 125 towns and villages in the Isle of Wight where we work. We also work in Southampton, about 17 miles from Freshwater.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Resist patching a failed seal with a tube from the DIY shop
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Common problems we fix in Freshwater
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
Around Freshwater, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- How long to leave it before use
- How much experience the applicator has
- How the colour is chosen
- Whether they’re fully insured
What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- The product the joint needs
- The size of the job
- Whether old sealant or filler has to be cut out
- Access and height
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The type of property
- Photos by email, if that is easy
- The problem you’ve noticed
- Access, such as stairs, a lift or height
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours in a single home, depending on the amount of work. Parking around Freshwater is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
Advice
How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
