Joints and finishes in Sandbank homes
Sandbank is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
In and around Sandbank, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Sandbank is about 7 miles west of Greenock, in Argyll and Bute. Sandbank gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

How we handle new build mastic in Sandbank
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have cracked sealant around new window and door frames and gaps between new skirting and floors, we can help, whatever the surface.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints
To keep the joints looking good and working properly:
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
- Follow the cure time we give you
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.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.

What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Do you need new build mastic in Sandbank?
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.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Gourock station, the sealant around baths, showers and frames is worth checking in the first year or two.

Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What information do you need?
A short description and the location. We’ll ask anything else we need to know.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
