Commercial sealant contractors for businesses in Moredun

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Different surfaces, different methods

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.

Commercial sealant contractors for commercial buildings in Moredun

Failed sealant isn’t always the whole story. A leak near a frame edge can start in the frame, the cill or the cavity, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant. We work on washrooms and tea points, window and door perimeters and external facade joints, and the failures we’re asked to look at most are gaps behind commercial kitchen worktops and sinks and expansion joints with the sealant torn out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Moredun is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Multi-site clients with buildings in and around Moredun can put several sites on one programme, so standards and paperwork match across every site.

Natural stone gives a lot of Scottish city premises their character: sandstone in most, granite in Aberdeen. Stone needs a neutral-cure sealant suited to it and a colour that sits quietly against the masonry.

A 12-month guarantee applies to all our work in Edinburgh. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we will come back to it.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. In a Scottish city, kerbside space and loading need planning, especially near the centre. Shared closes, stairs and the property factor may need to be part of the plan.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements

Advice

What Moredun’s businesses ask us to seal

Moredun lies within about 3 miles of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. A matched colour is only half the brief on an exposed frontage. Three care or nursing homes sit less than 2 miles from Moredun. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor.

For premises near Shawfair station (1.8 miles east of Moredun), footfall is part of the plan: work is phased so shops and offices keep trading. Sites a few miles apart, such as Craigmillar Shopping Centre and Peffermill Industrial Estate, can share one programme and one point of contact.

Moredun is about 3 miles north-west of Bonnyrigg, in Edinburgh. We cover Moredun, with the same fixed quotes and 12-month guarantee as everywhere else. Moredun is one of 174 places we cover in Edinburgh.

Business premises anywhere in EH17 and EH16 are within our area. Streets here include Drum Avenue, Gilmerton Road and Craigour Avenue, and sites on any of them can send details for a fixed quote. Access to Moredun is via the A772. Close to Moredun, our area also takes in Craigour (1 mile north-west), Fernieside (1 mile south-east), Ferniehill (1 mile south-east), Little France (1 mile north) and Ellen's Glen (1 mile south-west). Further afield, our area takes in Edinburgh (3 miles north-west), Leith (5 miles north), Bonnington (4 miles north-west), Greenside (4 miles north-west), Broughton (4 miles north-west) and Bellevue (4 miles north-west).

FAQs: Moredun

Does a coastal location like Moredun affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Does your area include sites such as Craigmillar Shopping Centre, near Moredun?

Yes. Our area takes in Moredun and its surroundings, with estates and business parks such as Craigmillar Shopping Centre included. A few photos and the unit address let us price the work.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Can one contractor look after sealant on all our buildings?

Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Could the old sealant in an older building contain asbestos?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Moredun can sit alongside others in a wider programme across Edinburgh.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Common problems we fix in Moredun

If sealant tears through its centre, it has failed cohesively. Typically the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds, which is why we look at the joint design as well.

These are often picked up first by site or facilities staff:

  • Untidy joints in a reception, shop floor or lobby
  • Weathered facade sealant that no longer flexes
  • Frame mastic that has hardened and come away from the wall
  • Gaps behind commercial kitchen worktops and sinks

If you look after units at a retail site such as Craigmillar Shopping Centre, which lies north of Moredun, shopfront perimeters and shop-fit joints are where a matched colour shows.

Questions to ask before you appoint anyone

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Respect the cure time before reopening an area
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Put external and wet-area joints on a regular inspection round
  • Make sure contractors see the asbestos survey before cutting out old mastic

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.

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, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Scottish city buildings take plenty of rain, and failed external joints let it into stone walls and around frames. Renewing them early protects the fabric.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
