Mastic sealing for businesses in Portincaple
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Travel to remote or island sites
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Removal of failed or old sealant
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- Whether an asbestos survey exists
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Mastic sealing in Portincaple
Before work starts, most agents and landlords want the documents in order. 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 window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks, and the usual reasons a site gets in touch are brittle perimeter mastic across a building and communal area joints that look neglected. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Portincaple, that means joint design, primers and backing rod as standard.
Around Portincaple, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. Renewing every failing joint on one visit is the sensible approach for a place like Portincaple. Photos of each area help us quote the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Broken glass or failed sealed units
- 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)
Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly.
Where we work in Portincaple
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal entrances and stairwells
- External wall and movement joints
Common problems we fix in Portincaple
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Typical triggers for a call:
- Damp patches beside frames
- Open joints in brickwork or panels
- The same joint failures repeated across a portfolio
- Draughts at frames across a block
For owners and agents with buildings in or around Portincaple, block-wide mastic programmes deal with frames and external joints of the same age together.
What to look for in a quote
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
Block-wide mastic in Portincaple
Portincaple 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, so it’s worth inspecting those sides more often. Portincaple is in the west of Scotland, the wetter side of the country. Exposed elevations on blocks take a soaking and their mastic shows it. Programmes allow for wet days.
If you look after a block within reach of Garelochhead station (1.4 miles south of Portincaple), frame and balcony mastic can be renewed on one programme.
Portincaple is about 8 miles north-west of Helensburgh, in Argyll and Bute. We cover commercial sites throughout Portincaple, whether it’s a single job or part of a planned programme.

Local landmarks in Portincaple

When to bring in a specialist
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Our process
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Tell us who will meet us and how to get in at your building near Portincaple. That goes into the plan alongside the quote.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Tell us which areas need to stay in use

Questions about Portincaple
Will you take on a block within reach of Garelochhead station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Portincaple off your patch?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
