FAQs for Collennan
Can you do new build mastic in Collennan?
Yes. Our work covers the whole of Scotland, and Collennan is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Collennan?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
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.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including the preparation. We will confirm how long when we quote.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
New build mastic for homes and businesses in Collennan
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on plot handovers, show homes and skirting & floors, and people most often call us about untidy sealant flagged on a snagging list and second-fix sealing on new plots.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Our work is backed for twelve months.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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. Everything old must be removed first.
What we are called out for in Collennan
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Signs it’s time to call us include:
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
In and around Collennan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- Which colour the sealant will be
- How the surfaces are prepared before sealing

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What affects the cost of new build mastic
You’ll get a clear quote before work begins. It takes into account:
- The amount of work
- How many areas need sealing
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- Photos by email, if that is easy
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
Every job is quoted individually, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send photos if you have them.
What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

New build mastic around Collennan
Collennan is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Collennan is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
If you’ve bought a new home near Barassie station, the sealant around baths, showers and frames is worth checking in the first year or two.

How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. Outside jobs in Collennan need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any tricky access

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
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Don’t seal over failed sealant yourself
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
