How we handle mastic sealing in Lybster
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. Most enquiries involve brittle perimeter mastic across a building and patchy repairs in mismatched sealant, across external wall and movement joints, window and door perimeters on blocks and communal entrances and stairwells. A specialist sealant contractor works differently from a general builder: on jobs in Lybster, preparation and product choice get the time they need.
In smaller Scottish places like Lybster, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we are asked in Lybster
Is Lybster too far out for you?
Not at all. Lybster is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Can one quote cover a number of our buildings near Lybster?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
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 asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.

Advice
Keeping the joints sound
To get the most from the new sealant:
- List the paperwork your organisation requires when you send details
- Avoid piecemeal callouts where you can
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Surface by surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Looking after buildings in and around Lybster
Lybster sits close to the coast, within about 1 mile. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Lybster is in the east of Scotland, which is drier than the west. Frost and condensation on winter mornings can still delay outside mastic. Programmes allow for that
Churches, halls and community buildings such as St Mary's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Owners near Lybster can renew frame and external mastic block by block on one programme.
Lybster is about 22 miles south-east of Thurso, in Highland. Anywhere in KW3, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Highland coverage takes in 256 places.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Failed window or door frames, which need a window contractor
- Asbestos-containing sealant, which we don’t remove
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Why act early in Lybster
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
