New build mastic for homes and businesses in Newtongrange
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you’re dealing with gaps opening as the house dries out and settles and leaking shower tray seals in a new home, we can help, on bathrooms & en suites, show homes and kitchens alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can. We’ll tell you if anything on it is not a sealant job.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Raise failed sealant with the developer while you are covered
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours in a single home, depending on the amount of work. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Signs you need new build mastic in Newtongrange
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
- Cracked caulk along new skirting
If you’ve bought a new home near Newtongrange station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- How long to leave it before use
- What product goes in the joint
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
