New Build Mastic in Killin
Professional new build mastic in and around Killin, with old sealant always removed completely and a 12-month guarantee.
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours in a single home. Outside jobs in Killin need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
How to get a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Advice
How we handle new build mastic in Killin
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. Typical jobs include sealant applied over dusty or wet surfaces and cracked sealant around new window and door frames, across kitchens, windows & doors and show homes.
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.
Whatever the size of the job, you get the same 12-month guarantee.

- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Any previous sealing or DIY work
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Joints and finishes in Killin homes
Killin 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. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Killin, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Landlord and commercial work in Killin
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, 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.
Your questions about new build mastic in Killin
Do you cover Killin for new build mastic?
Yes. Our work covers the whole of Scotland, and Killin is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is Killin within the area you cover?
Yes, Killin is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
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.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we will tell you the cure time.
How long will you be here?
That depends on how much there is to do, but as a guide it takes a few hours in a single home. We’ll tell you when we quote.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
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.
Do you need new build mastic in Killin?
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Any of these means the joints need attention:
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
- Shower seals failing in the first year or two
For jobs in and around Killin, choosing the right material for each joint is as important as a tidy finish.
Before you book anyone
- Whether the sealant suits the joint
- Is VAT in the price?
- Which colour the sealant will be
- Whether they’re fully insured
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Photograph failed sealant before it’s redone
- Check bath and shower seals every few months as the house settles
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
