New build mastic in Coldingham
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. If you have skirting joints opening in the first winter and joints pulling apart as timber shrinks, we can put it right, on windows & doors, bathrooms & en suites and show homes alike.
Around smaller Scottish places like Coldingham, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Keeping the joints in good condition
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
- Keep pictures and emails about snagging items
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours in a single home. Somewhere like Coldingham may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

What the job involves on each surface
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 that suits the frame.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
What else we do in Coldingham
New build mastic around Coldingham
Coldingham is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Coldingham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Reston station, it’s worth checking the sealant early, while snags are still fresh.

Can new sealant go on top of the old bead?
