Construction mastic for commercial buildings in North Middleton
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. If you have caulk cracking where joints are moving more than expected and mastic snags holding up handover, we can put it right. Searching for sealant specialists in North Middleton? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Sites near smaller places like North Middleton can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Exposed buildings in Scotland take a lot of weather, and for a smaller place like North Middleton, a repair visit takes planning, so it’s better to act early.
Pricing mastic packages depends on quantities, condition and access. Call for a quote.

Facades, frames and programmes in North Middleton
Being in the east of Scotland, North Middleton gets less rain than the west coast. Winter mornings can still bring frost and condensation on steel and glass. We programme around it with the site team. Scotland has its own building regulations, and in North Middleton warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant.
For a contractor working at a hospital such as Midlothian Community Hospital (4.9 miles north-west of North Middleton), perimeter and facade sealing is planned around patients and deliveries.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Allow flexibility for external sealing in damp or cold weather
- Put any product change through the designer first
- Keep scrapers and abrasive pads off new beads
- Don’t schedule sealing before decorators and flooring are done
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.

Your questions answered
Is North Middleton too small for you to travel to?
Not at all. North Middleton is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you work on a hospital site such as Midlothian Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you seal on top of existing sealant?
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.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
What do you charge?
Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or send photos by email.
Can you fit around our programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Rework caused by others damaging completed areas
- Designing joint widths or choosing the specification (that sits with the designer)
- Oversized gaps that need packing or adjustment by others
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What the job involves on each surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Common problems we fix in North Middleton
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Site and facilities staff are often the first to spot these:
- Inconsistent sealant finishes from plot to plot
- Existing joints on a refurb that need cutting out and resealing
- Missed perimeter joints on a new elevation
- Bath and shower joints scraped during the final clean
Hotel extensions and refits, at places such as Borthwick Castle Hotel, 0.8 miles north-east of North Middleton, usually run between busy periods, so the sealing is squeezed into short windows.
