Anderston New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for Anderston, backed by a 12-month guarantee. Ask us for a quote.
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Sealant that never bonded to the surface
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Raise failed sealant with the developer while you are covered
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
New build mastic in Anderston
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on windows & doors, bathrooms & en suites and plot handovers, and common reasons people get in touch are second-fix sealing on new plots and cracked caulk along new skirting.
In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. In Anderston, a flexible sealant suits those joints better than filler.
Whatever the size of the job, it’s backed by our 12-month guarantee in Anderston and across Glasgow.

Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What colour sealant will you use?

Related advice
Why it’s worth doing now in Anderston
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Anderston, damp can travel a long way before it shows.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.

Signs you need new build mastic in Anderston
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Most people get in touch when they notice one of these:
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
In and around Anderston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Which sealant they’ll use, and why
- Whether VAT is included
- Who turns up on the day
- How hidden problems are handled
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

New homes and floors in Anderston
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. 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.
For new homes near Charing Cross (Glasgow) station, it’s worth checking the sealant early, while snags are still fresh.
