About our new build mastic in Elmstead
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We are often asked to deal with worktop and upstand sealant coming away and messy sealant that spoils new finishes, across plot handovers, windows & doors and skirting & floors.
Older homes in small places like Elmstead often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, it’s backed by our 12-month guarantee in Elmstead and across Essex.

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Elmstead needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Keeping the joints in good condition
So the new joints stay in good condition:
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
- Keep photos and emails about snagging items
- Watch for new gaps as the house dries out
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
