- Skirting joints opening in the first winter

What we are called out for in Westcott
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracked sealant shows up.
Any of these means the joints need attention:
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Sealant applied over dusty or wet surfaces
For new homes near Aylesbury Vale Parkway station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Westcott
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on plot handovers, windows & doors and kitchens, and common reasons people get in touch are frame joints opening as the plaster dries and beads laid onto grit and dust from the build.
For a small place like Westcott, the journey and access are planned in advance, and the work itself is the same as on any site.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

How long does the job take?

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Westcott, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Clear the area around the work
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Related advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Aftercare tips
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
- Follow the cure time we give you
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes 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.
