About our new build mastic in Bàgh a'Chaisteil
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you have cracked sealant around new window and door frames and skirting joints opening in the first winter, we can help, on plot handovers, windows & doors and kitchens alike.
Around smaller Scottish places like Bàgh a'Chaisteil, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Bàgh a'Chaisteil
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- Which sealant suits the joint
- Any working-time requirements on site
- Access and height
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, email us at info@mrmastic.co.uk.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
- Watch for new gaps as the house dries out
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What the job involves on each surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

What do you need from me for a quote?

What we’re called out for in Bàgh a'Chaisteil
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
If you can see any of these, it’s time to have the joints looked at:
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
Whether the job is in Bàgh a'Chaisteil itself or nearby, the right material for each joint matters as much as a neat finish.
