Mastic sealing in Geirinis
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints, and the failures we are asked to look at most are estate-wide sealant that is simply worn out and occupiers reporting cold air round windows. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Geirinis is the same: the right product in a properly prepared joint.
In smaller Scottish places like Geirinis, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Your questions answered
Can one quote cover a number of our buildings near Geirinis?
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 Geirinis inside the area you cover, given it’s on an island?
Yes, Geirinis 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.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.

Geirinis is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Being on an island, Geirinis means planning around ferry times as well as the weather. Send photos and addresses so every building can be covered on as few trips as possible.
Wherever your building is in or near Geirinis, we look at the whole elevation before quoting, so you know what needs doing now. For owners and agents with buildings in or around Geirinis, block-wide mastic programmes deal with frames and external joints of the same age together.

General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
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.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs near Geirinis are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
What we need from you
- Confirm the product named in the specification
- Send your site hours and access windows
- Explain the parking and delivery arrangements
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

What sets the cost
These are the things that shape the price:
- The size and state of each joint
- Any access equipment needed
- How much there is to seal
- The site’s rules and procedures
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- When you need the work done
- Approximate linear metres or a joint schedule
- The postcode of the building
- Clear photographs of the problem areas
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Where we work in Geirinis
- Window and door perimeters on blocks
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
- Check the asbestos register before any old mastic is disturbed
- List the paperwork your organisation requires when you send details
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
Owners, agents and contractors
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
