About our new build mastic in Row Town
We work in new homes and on new-build sites across Row Town. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you have sealant applied over dusty or wet surfaces and frame joints opening as the plaster dries, we can help.
If you’ve bought a new home in or near Row Town, 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.
All of our work is guaranteed for twelve months.

What we can’t put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Bathrooms & en suites
- Windows & doors
- Show homes
- Plot handovers
- Kitchens
- Skirting & floors
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
What happens if it’s left?
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. Homes in smaller places like Row Town can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Whether the work is at height
- The product the joint needs
- Any mould that needs treating
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

There’s no need for technical detail. It helps if you can tell us:
- Whether it has been sealed before
- The address or postcode of the job
- The problem you’ve noticed
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
New build mastic in Row Town: local notes
