Joints and finishes in Balfour homes
Balfour is within about 3 miles of 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. Island jobs need planning around ferries and the weather, so the more notice, the better.
In and around Balfour, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Balfour
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. Typical jobs include sealant applied over dusty or wet surfaces and plot mastic for developers ahead of handover, on show homes, skirting & floors and windows & doors.
Around smaller Scottish places like Balfour, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Every job is covered by a 12-month guarantee, wherever you are in the Orkney Islands.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Get a leaking seal dealt with straight away
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
When to call us in Balfour
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People generally contact us after spotting something like this:
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
- Joints pulling apart as timber shrinks
For jobs in and around Balfour, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before you book
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- What happens if the job turns out different
- How the surfaces are prepared before sealing

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours in a single home, depending on how much there is to do. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Landlords, agents and businesses in Balfour
Mouldy or split sealant often shows up at the end of a tenancy. 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.

Balfour: your questions answered
Will you come out to Balfour?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on new build mastic in Balfour?
All our work, in Balfour and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Why does sealant fail so quickly in new builds?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
