Mastic sealing in Aithsetter, done properly
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on external wall and movement joints, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are damp patches beside frames and failed external movement joints. One point of contact handles commercial sealant work in Aithsetter from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around Aithsetter, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Aithsetter, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Confirm the product named in the specification
- Make sure the joints can be reached

Advice
Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Why act early in Aithsetter
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. Around smaller places like Aithsetter, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Your questions answered
Does the sea air around Aithsetter change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Do you work on the island where Aithsetter is?
Yes, Aithsetter is within the area we cover. Every Scottish council area is within our area. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
What will the job cost?
Every job gets its own fixed quote. For yours, call 01277 525 020 or send photos by email.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
