How we handle new build mastic in Molehill Green
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. We work on plot handovers, skirting & floors and windows & doors, and common reasons people get in touch are gaps between new skirting and floors and frame joints opening as the plaster dries.
For a small place like Molehill Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee.

Skirting and floors

The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. In a small place like Molehill Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

What we’re called out for in Molehill Green
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
Keep an eye out for any of the following:
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
- Gaps between new skirting and floors
For new homes near Stansted Airport station, it’s worth checking the sealant early, while snags are still fresh.

To help us quote quickly, let us know:
- Access, such as stairs, a lift or height

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
