New homes and floors in Branstone
Branstone is within about 3 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Shanklin station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Branstone, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Branstone
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on plot handovers, show homes and skirting & floors, and people most often call us about gaps between new skirting and floors and sealant that never bonded to the surface.
For a small place like Branstone, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
After the cure time, these simple habits help:
- Report sealant problems to your builder during the snagging period
- Resist patching a failed seal with a tube from the DIY shop
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Early snagging is easier snagging. Small faults turn into leaks if left.
How we quote for new build mastic
For a quick quote, just ask. What matters most is:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Whether there’s mould to deal with
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- The rough size of the job
- Access, such as stairs, a lift or height
- If someone has resealed it before
- Whether it’s a home or a business
Need a quote? Please ring 0345 464 0079 or email us and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Branstone, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Branstone questions
Do you work for landlords with property near Shanklin station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover Branstone for new build mastic?
Yes. Our work covers London and the South East, and Branstone is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you do plot mastic on a new development?
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.

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In a small place like Branstone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What sealant work cannot fix
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:
- Damaged fittings that need replacing
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
