How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
New build mastic for homes and businesses in Gatehouse of Fleet
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, plot handovers and skirting & floors, and common reasons people get in touch are skirting joints opening in the first winter and plot mastic for developers ahead of handover.
Work in a place like Gatehouse of Fleet is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Every job comes with our 12-month guarantee.

What new build mastic looks like in Gatehouse of Fleet
Gatehouse of Fleet 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. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Whether the job is in Gatehouse of Fleet itself or nearby, the right material for each joint matters as much as a neat finish.

FAQs for Gatehouse of Fleet
What guarantee comes with new build mastic in Gatehouse of Fleet?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Gatehouse of Fleet?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
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.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
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.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.

Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, send an email to info@mrmastic.co.uk with photos and we’ll tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What we’re called out for in Gatehouse of Fleet
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
The most common problems we see are:
- Kitchen sealant that has pulled off the wall
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
In and around Gatehouse of Fleet, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
- Follow the cure time we give you
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
