New Build Mastic in Bunessan
We cover Bunessan for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Skirting joints opening in the first winter
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Bunessan may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
How we handle new build mastic in Bunessan
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. If you’re dealing with second-fix sealing on new plots and skirting joints opening in the first winter, we can put it right.
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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

FAQs for Bunessan
Will you come out to Bunessan?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Bunessan in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Bunessan is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How much does new build mastic cost in Bunessan?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Different surfaces, different methods
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Keep pictures and emails about snagging items
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
New build mastic in Bunessan: local notes
Bunessan 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. Bunessan 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.
In and around Bunessan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. Whether the job is in Bunessan itself or nearby, the right material for each joint matters as much as a neat finish.

Why it’s worth doing now in Bunessan
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In an older home around Bunessan, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- The old material and how stubborn it is
- The amount of work
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
