What new build mastic looks like in Barwick

New build mastic in Barwick, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you’re dealing with cracked sealant around new window and door frames and messy sealant that spoils new finishes, we can help, on kitchens, bathrooms & en suites and plot handovers alike.
Older homes in small places like Barwick often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All of our work is guaranteed for twelve months, in Barwick and everywhere else we cover.

What else we do in Barwick
When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Cracked trays, tiles or worktops
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Kitchens
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Plot handovers
- Windows & doors
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Raise failed sealant with the developer while you’re covered
- Look at the sealant regularly in the first couple of years
- Keep pictures and emails about snagging items
- Follow the cure time we give you
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
What we’re called out for in Barwick
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Signs it’s time to call us include:
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
In and around Barwick, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Around Barwick, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

- 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.
