How we handle new build mastic in Nash Street
Across Nash Street, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you have sealant work across a run of new homes and shower seals failing in the first year or two, we can help.
In a village or hamlet like Nash Street, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee, large or small.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours in a single home. Somewhere like Nash Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive

Advice
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
- Wipe joints with warm soapy water
- Don’t seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Why act early in Nash Street
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote. Around Nash Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Common problems we fix in Nash Street
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Signs it’s time to call us include:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
Around Nash Street, as everywhere, new build mastic is only as good as the preparation behind it.
