About our new build mastic in Ganavan
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We’re often asked to deal with messy sealant that spoils new finishes and cracked sealant around new window and door frames, across kitchens, windows & doors and plot handovers.
For a place like Ganavan, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
You get a 12-month guarantee, the same in Ganavan as everywhere else we work.

Do you need new build mastic in Ganavan?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Keep an eye out for these signs:
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
Around Ganavan, as everywhere, new build mastic is only as good as the preparation behind it.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
FAQs for Ganavan
Can you help a landlord with a rental near Oban station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Ganavan?
Yes. Ganavan is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Look at the sealant regularly in the first couple of years
- Do not seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Keep pictures and emails about snagging items
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In an older home around Ganavan, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

How the job changes by surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
When it isn’t the sealant
We won’t take on work that won’t last, so these are the limits:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Plot handovers
- Skirting & floors
- Show homes
- Windows & doors
- Bathrooms & en suites

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention any tricky access
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

New homes and floors in Ganavan
