Commercial mastic work in Old Pentland
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. We work on movement joints in walls and floors, external facade joints and washrooms and tea points, and the failures we’re asked to look at most are smeared sealant across finishes from a rushed job and a top-up bead over failed sealant, now lifting. Most enquiries from Old Pentland start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Occupied buildings in Old Pentland need the work phased: we agree the order with you and hand back each area with its cure time.
Around smaller places such as Old Pentland, the commercial buildings tend to be hospitality, local shops, schools, health centres and converted rural buildings. Each has kitchens, washrooms and frames that depend on sound joints.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Building owners, agents and FMs in Old Pentland
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
What happens if it’s left?
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. Where it helps, we quote a patch and a full reseal side by side. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs near Old Pentland are often grouped with others in the same area. Let us know if your dates have any give.
- We start with the evidence: photos, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings

Shops, offices and hotels in and around Old Pentland
At least three named trading, business or retail sites lie within about 3 miles of Old Pentland. Each new occupier on a park like these tends to refit, from reception to staff kitchen. Being in the east of Scotland, Old Pentland gets less rain than the west coast. Cold snaps still affect when external joints can be sealed. Outside work is booked with that in mind
Offices and shops close to stations such as Slateford station, 3.8 miles north-west of Old Pentland, tend to be busy all day, so sealant work is planned around opening hours. If you have premises on more than one site, say at Straiton Retail Park and Pentland Industrial Park, one contractor and one quote can cover both. Units at retail parks like Straiton Retail Park (to the south-east of Old Pentland) change hands and get refitted, with new joints at every frontage.

What sets the cost
A fixed quote reflects the actual work. It allows for:
- Phasing around occupants
- Which sealant the job calls for
- Induction, permit and paperwork requirements
- The total length or number of joints
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- The product your specification calls for
- Where the site is, with the postcode

- Access details, including height

Different surfaces, different methods
Shop fronts and retail fit-outs
Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal, often in a colour to suit the brand finish. Colour options are confirmed with the quote.
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.
What else we do in Old Pentland
After the work
To get the most from the new sealant:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Respect the cure time before reopening an area
- Check the asbestos register before anyone disturbs old sealant in an older building
- Note dates and locations of sealant work for future planning
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
Old Pentland: questions and answers
Do you cover business parks and estates near Old Pentland, such as Straiton Retail Park?
Yes. We cover Old Pentland and the area around it, including industrial estates, business parks and retail parks such as Straiton Retail Park. A few photos and the unit address let us price the work.
Is a smaller place like Old Pentland outside your area?
Not at all. Old Pentland is within our area. We cover the whole of Scotland. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
