About our new build mastic in Tapnage
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. Typical jobs include second-fix sealing on new plots and joints pulling apart as timber shrinks, across skirting & floors, kitchens and plot handovers.
Older homes in small places like Tapnage often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant

What the job involves on each surface

Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Tapnage, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Tapnage needs a little journey planning: 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.
- 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.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Tapnage
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Shower seals failing in the first year or two
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
In and around Tapnage, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Tapnage: your questions answered
I let a flat near Swanwick station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Will you come out to Tapnage?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room before we begin.
Should I wait before resealing?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Are you insured?
Yes. We are fully insured.
What information do you need?
Tell us what needs doing and where. We will ask anything else we need to know.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Raise failed sealant with the developer while you are covered
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
