New build mastic in Balgay, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. We work on bathrooms & en suites, skirting & floors and windows & doors, and the jobs we see most are new-build shower sealant that has already split and sealant applied over dusty or wet surfaces.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags, in Balgay as anywhere.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. Inside a flat in Balgay, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
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.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common problems we fix in Balgay
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Most people get in touch after spotting one of these:
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- Cracks appearing as a new home settles
If you’ve bought a new home near Invergowrie station, the sealant around baths, showers and frames is worth checking in the first year or two.

New build mastic around Balgay
Balgay is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Balgay, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
- Use the extractor fan every time you shower
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.

Why act early in Balgay
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Balgay, damp can travel a long way before it shows.
