Cost factors for mastic joints
What shapes the price:
- Joint width, depth and condition
- Location, for remote and island sites
- The product specified
- Working within restricted access windows
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Your programme or deadline
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- The product your specification calls for
To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
How we handle mastic sealing in Monreith
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Most enquiries involve cracked, hardened mastic round windows on a block and mastic failing across several blocks on an estate, on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. One point of contact handles commercial sealant work in Monreith from the first photos to the final walk-round, for single jobs and planned programmes alike.
In smaller Scottish places like Monreith, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Every job we finish is backed by a 12-month workmanship guarantee, in Monreith as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. Renewing every failing joint on one visit is the sensible approach for a place like Monreith. Send photos and we’ll quote for everything together.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

Common questions from Monreith clients
Will you price a mastic programme across our Monreith portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Is Monreith off your patch?
Not at all: smaller places are covered as well as towns. 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.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can people stay in the building while you reseal?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Aftercare for building managers
For the best life from the joints:
- Prioritise elevations facing the weather
- Mention RAMS, insurance or CSCS requirements up front
- Have the asbestos survey to hand for older buildings
- Avoid piecemeal callouts where you can
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
For owners and agents in Monreith
Monreith sits close to the coast, within about 1 mile. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. Monreith is in the west of Scotland, the wetter side of the country. The most exposed elevations need checking most often. We plan block programmes with the forecast in mind.
For owners and agents with buildings in or around Monreith, block-wide mastic programmes deal with frames and external joints of the same age together.
