How we handle new build mastic in Great Mongeham
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on kitchens, show homes and plot handovers, and common reasons people get in touch are beads laid onto grit and dust from the build and internal frame sealant that has split.
Somewhere as small as Great Mongeham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, in Great Mongeham and everywhere else we cover.

What happens if it’s left?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. In a small place like Great Mongeham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit generally 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.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
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.

New build mastic around Great Mongeham
Great Mongeham is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Great Mongeham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Walmer station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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 fails, we can still redo it.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Great Mongeham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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 down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
