How we handle new build mastic in Beamond End
We work in new homes and on new-build sites across Beamond End. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. Common call-outs are for cracked caulk along new skirting and sealant applied over dusty or wet surfaces, on skirting & floors, kitchens and windows & doors.
In a village or hamlet like Beamond End, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
New homes and floors in Beamond End
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Great Missenden station, it’s worth checking the sealant early, while snags are still fresh. Around Beamond End, as everywhere, new build mastic is only as good as the preparation behind it.

What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Movement caused by a poorly fitted tray or bath
- Plumbing faults behind the sealant
- Disputes or warranty claims with your builder
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Beamond End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What the job involves on each surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
What we do, step by step
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours in a single home. In a small place like Beamond End, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
