What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
About our new build mastic in Binsey
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, because that’s what rushed new-build sealant normally lacks. We work on windows & doors, kitchens and show homes, and common reasons people get in touch are messy sealant that spoils new finishes and gaps between new skirting and floors.
In a village or hamlet like Binsey, 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.
There’s a 12-month guarantee on every job, large or small.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Binsey, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Binsey can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

When it is not the sealant
It helps to know what we cannot do too:
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Binsey questions
Will you come out to Binsey?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Oxford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Why has my new-build shower seal failed already?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll say how long yours will take.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
When to call us in Binsey
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch after spotting one of these:
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
Around Binsey, as everywhere, new build mastic is only as good as the preparation behind it.
