New Build Mastic in Sherington
Our applicators work in Sherington on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
- Sealant that never bonded to the surface
How we handle new build mastic in Sherington
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you have kitchen sealant that has pulled off the wall and sealant that never bonded to the surface, we can help, on skirting & floors, kitchens and plot handovers alike.
Around Sherington, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots. Your quote will say how long we expect yours to take.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something is not sealant, we will say so.
How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Sherington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
When to call us in Sherington
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Look out for any of the following:
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
In and around Sherington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Whether all the old sealant comes out first
- How hidden problems are handled
- How long to leave it before use
- How the joint is cleaned and prepared
Aftercare tips
Looking after new joints is easy:
- Photograph failed sealant before it’s redone
- Do not wait for the house to settle if water is getting through
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
