New Build Mastic in Flexford
We cover Flexford for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Smeared, uneven beads picked up at snagging
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
New build mastic for homes and businesses in Flexford
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on show homes, windows & doors and plot handovers, and the jobs we see most are sealant that never bonded to the surface and messy sealant that spoils new finishes.
Older homes in small places like Flexford often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Flexford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Flexford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
Advice
Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Landlords, agents and businesses in Flexford
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
If you manage several properties in or around Flexford, several properties can be quoted together. Just tell us the addresses and what each one needs.
Looking after it afterwards
To keep the joints looking good and working properly:
- Record problems with dated pictures
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

Signs it’s time to call us include:
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
