Wasbister: questions and answers
Can one quote cover a number of our buildings near Wasbister?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Wasbister inside the area you cover, given it’s on an island?
Yes, Wasbister is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. Ferry times and the weather set the plan, so we ask for photos and a full list first.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
About our mastic sealing in Wasbister
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Most enquiries involve draughts at frames across a block and communal area joints that look neglected, across shopfronts below residential blocks, balcony and threshold joints and external wall and movement joints. Facilities teams, main contractors and managing agents in Wasbister tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In smaller Scottish places like Wasbister, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Asbestos-containing sealant, which we don’t remove
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
If you’re not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Communal kitchens and washrooms
- External wall and movement joints
- Communal entrances and stairwells
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Wasbister, a repair visit takes planning, so it’s better to act early.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent and easier to manage.
When to call us in Wasbister
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Things that typically lead to an enquiry:
- Mastic failing across several blocks on an estate
- Draught complaints from residents or tenants
- Leaks at window and door perimeters
- Patchy repairs in mismatched sealant
Older buildings near Wasbister, from historic houses such as Skaill House (to the north-west of Wasbister) to more modest stock, need compatible products when frames are resealed.
