Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Open a window or run the fan after bathing
- Wait for the cure time before using a resealed shower
- Raise failed sealant with the developer while you’re covered
- Clean sealant with mild detergent, not abrasives
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Around Little Gaddesden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Little Gaddesden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.

Signs you need new build mastic in Little Gaddesden
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
These are the problems we are asked about most:
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
Around Little Gaddesden, as everywhere, new build mastic is only as good as the preparation behind it.
