- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
Leave it or put it right?
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. Around Stonesfield, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before we start.

How we handle new build mastic in Stonesfield
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. We work on plot handovers, kitchens and skirting & floors, and the jobs we see most are gaps between new skirting and floors and untidy sealant flagged on a snagging list.
Work in a small place like Stonesfield just needs the journey and access planning, and once on site, the job is the same as anywhere.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

The process
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 starts. The work usually takes a few hours in a single home. Somewhere as small as Stonesfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Act quickly if a seal starts to leak
- Raise failed sealant with the developer while you are covered
- Record problems with dated photos
- Wipe joints with warm soapy water
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
