Mastic sealing for commercial buildings in Dewartown
Across Dewartown and the rest of Midlothian, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. Site teams most often ask us about damp patches beside frames and movement joints with sealant missing, across communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dewartown, preparation and product choice get the time they need.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Dewartown is planned with the forecast. We agree a window with some flexibility.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Frames, entrances and external joints in Dewartown
Dewartown is in the east of Scotland, which is drier than the west. Frost and condensation on winter mornings can still delay outside mastic. Block programmes are built with that in mind
For owners of several units at places like McSence Business Park (1.8 miles west of Dewartown), one programme can deal with frame and external mastic across the lot. Older buildings near Dewartown, from historic houses such as Melville Castle (4.6 miles west of Dewartown) to more modest stock, need compatible products when frames are resealed. Buildings close to stations like Gorebridge station (to the south-west of Dewartown) are often flats over shops, with frame mastic to keep sound.

Why it’s worth doing now in Dewartown
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Dewartown before they leak.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Cost factors for mastic joints
What shapes the price:
- Travel to remote or island sites
- Access and working height
- How much existing material needs removing
- Backing rod, priming and other preparation
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- When you need the work done

- A wide shot and a close-up of the area
- How the joints are reached, and at what height

Communal areas

Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

FAQs: Dewartown
Will you take on a block within reach of Gorebridge station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you work at a site such as McSence Business Park, by Dewartown?
Yes, sites like McSence Business Park are within our area, along with the rest of Dewartown. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
