Portnahaven: questions and answers
Is Portnahaven off your patch?
No. Small places get the same service as large ones. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does a coastal location like Portnahaven affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can you supply RAMS and insurance details?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
How do you keep disruption to occupiers down?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

What else we do in Portnahaven
What affects the price in Portnahaven
Each job is priced on its own details. The main factors are:
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- Any access equipment needed
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- What the building is and how it’s used
- When you need the work done
- Whether an asbestos survey exists
- The postcode of the building
For a fixed quote, phone 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What we are called out for in Portnahaven
A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.
Any of the following is a good reason to get the joints checked over:
- Movement joints packed with grit and debris
- Layers of sealant, all of them failing
- Mouldy silicone around WCs, urinals and vanity tops
- Damp patches where an external joint has failed
Where a joint is on show in Portnahaven, we’ll check which shades the product offers before work starts.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
Leave it or put it right?
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after. We can price both options so you can decide on the facts. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Portnahaven, a repair visit takes planning, so it’s better to act early.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

For work around Portnahaven, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.

What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Old mastic that tests positive for asbestos
- A dripping trap, valve or pipe behind a fitting
- Cracking that needs a structural engineer to look at it
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.
What we seal
- External facade joints
- Window and door perimeters
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Floor and threshold joints
- Movement joints in walls and floors
Sealant on show in Portnahaven’s commercial buildings
With the shore within about 1 mile, Portnahaven counts as a coastal location. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. The west of Scotland, where Portnahaven is, gets more rain than the east. Outside sealing needs dry spells and a programme that can move a little. Weather-facing frames tend to need resealing before the sheltered ones
For any commercial premises in Portnahaven, a lasting joint depends on full removal of the old sealant and clean, dry faces.
