About our new build mastic in Garelochhead
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We’re often asked to deal with plot mastic for developers ahead of handover and leaking shower tray seals in a new home, on windows & doors, show homes and kitchens.
Around smaller Scottish places like Garelochhead, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All our work comes with our 12-month guarantee.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots from start to finish. For a place like Garelochhead, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

What we’re called out for in Garelochhead
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
For new homes near Garelochhead station, it’s worth checking the sealant early, while snags are still fresh.

FAQs for Garelochhead
Can you help a landlord with a rental near Garelochhead station?
Yes, we work for landlords and 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 work begins.
Do you cover smaller places like Garelochhead?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the number of plots. We will give you a better idea when we quote.
Is it normal for sealant to crack in a new home?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, 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.
Landlords, agents and businesses in Garelochhead
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What new build mastic looks like in Garelochhead
Garelochhead is close to 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. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
In and around Garelochhead, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. In a place like Garelochhead, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
