How we handle mastic sealing in Lochranza
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on communal kitchens and washrooms, communal entrances and stairwells and balcony and threshold joints, and the failures we’re asked to look at most are old repairs sealed over failed mastic and repeated reactive repairs to the same buildings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lochranza is the same: the right product in a properly prepared joint.
Around Lochranza, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
Work we carry out in North Ayrshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email the details over and we’ll come back to it.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Prioritise elevations facing the weather
- List the paperwork your organisation requires when you send details
- Make it easy for occupiers to report draughts
- Have the asbestos survey to hand for older buildings
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

Should maintenance staff do it?
Certain joints really need a specialist: 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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Lochranza, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- We inspect the joints, building by building, and record what has failed and why.
- 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.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready

Mastic sealing in Lochranza: the local picture
Lochranza lies within about 1 mile of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Lochranza is on Scotland’s wetter western side. Frame mastic on weather-facing sides tends to fail first. We plan block programmes with the forecast in mind.
For owners and agents with buildings in or around Lochranza, block-wide mastic programmes deal with frames and external joints of the same age together. Churches, halls and community buildings such as Castlekirk are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

FAQs: Lochranza
Is Lochranza too far out for you?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does a coastal location like Lochranza affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.
Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Materials that need asbestos testing before work
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.
