New build mastic in Elstead
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. Typical jobs include smeared, uneven beads picked up at snagging and internal frame sealant that has split, on kitchens, bathrooms & en suites and plot handovers.
Where new homes go up in smaller places like Elstead, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. For a job in Elstead, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children

Advice
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Why act early in Elstead
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Homes in smaller places like Elstead can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Common problems we fix in Elstead
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
The most common problems we see are:
- Sealant applied over dusty or wet surfaces
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
If you’ve bought a new home near Milford (Surrey) station, the sealant around baths, showers and frames is worth checking in the first year or two.
