New build mastic for homes and businesses in Stromness
We work in new homes and on new-build sites across Stromness. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you are dealing with untidy sealant flagged on a snagging list and second-fix sealing on new plots, we can put it right, on show homes, plot handovers and windows & doors alike.
For a place like Stromness, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.

How to look after the new joints
So the new joints stay in good condition:
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
- Get a leaking seal dealt with right away
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

New homes and floors in Stromness
Stromness 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.
Whether the job is in Stromness itself or nearby, the right material for each joint matters as much as a neat finish.

When to call us in Stromness
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
Common reasons people contact us include:
- Sealant that never bonded to the surface
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
In and around Stromness, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether all the old sealant comes out first
- The length of the guarantee
- Whether the sealant suits the joint
- Who turns up on the day
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. In a place like Stromness, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Your questions about new build mastic in Stromness
What guarantee comes with new build mastic in Stromness?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Stromness?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I wait before resealing?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where are you based?
We work from Crawley. We cover Stromness and the rest of the Orkney Islands.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
It helps to know what we can’t do:
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
