New build mastic in Crombie
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 show homes, and common reasons people get in touch are sealant work across a run of new homes and new-build shower sealant that has already split.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How the job changes by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Your questions about new build mastic in Crombie
I let a flat near Dunfermline City station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Is Crombie in your area for new build mastic?
Yes, Crombie is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What do you need from me for a quote?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In an older home around Crombie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Signs you need new build mastic in Crombie
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
It’s worth asking for a quote if you see:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
- Joints pulling apart as timber shrinks
Around Crombie, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Are they insured?
- What happens if the job turns out different
- How much experience the applicator has
- When the joint can take water or movement

What new build mastic looks like in Crombie
Crombie is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Dunfermline City station, it’s worth checking the sealant early, while snags are still fresh.

- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
