New Build Mastic in Craigour
New-build sealant joints in Craigour need attention? We cut out the old, prepare the joints and apply the right sealant.
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
New build mastic in Craigour
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have gaps behind new kitchen upstands and sealant work across a run of new homes, we can put it right, on plot handovers, bathrooms & en suites and show homes alike.
New flats and houses are still being built in and around Scotland’s cities, and new-home owners often find sealant snags in the first year or two.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Common problems we fix in Craigour
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
People generally contact us after spotting one of these:
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
In and around Craigour, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Who turns up on the day
- What guarantee comes with the work
- Which sealant they’ll use, and why
- What the cure time is
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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, and the work is guaranteed for a year.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Raise failed sealant with the developer while you are covered
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
FAQs for Craigour
Is new build mastic in Craigour guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
I let a flat near Shawfair station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is it normal for sealant to crack in a new home?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.

What else we do in Craigour
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- The number and length of the joints
- Whether the work is at height
- Mould in or behind the old joints
Doing several joints on one visit usually makes better use of the time than several visits. We will give you a clear price for the lot.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The type of property
- The address or postcode of the job
- The problem you’ve noticed
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Joints and finishes in Craigour homes
Craigour 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Shawfair station, the sealant around baths, showers and frames is worth checking in the first year or two.
