Sealant applicators in Gowkshill

We have applied sealant on commercial sites for over 20 years: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. Most enquiries involve gaps behind commercial kitchen worktops and sinks and frame mastic that has hardened and come away from the wall, on kitchen worktops and splashbacks, window and door perimeters and external facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Gowkshill, preparation and product choice get the time they need.

In Gowkshill, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

For a job around Gowkshill, the Scottish weather is part of the planning: sealant needs a dry joint and the right temperature, so external work has a weather window built in. Indoor work isn’t held up by rain.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Walls or slabs moving more than any sealant can take
  • A dripping trap, valve or pipe behind a fitting

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Surfaces we seal

  • External facade joints
  • Floor and threshold joints
  • Movement joints in walls and floors
  • Washrooms and tea points
  • Window and door perimeters
  • Kitchen worktops and splashbacks

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Tell us who will meet us and how to get in at your building near Gowkshill. That goes into the plan alongside the quote.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use

Commercial premises in Gowkshill

There are a number of hotels within about 2 miles of Gowkshill. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let. Gowkshill is on Scotland’s drier eastern side. Frost and condensation on winter mornings can still hold up external sealing. We plan external frontages and frames around that

In hotels such as Kirkhill Hotel, which lies south-west of Gowkshill, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. A unit on an estate like Butlerfield Industrial Estate, 0.6 miles west of Gowkshill, normally has an office front, a trade counter and staff facilities with joints of their own.

Gowkshill is about 2 miles south-east of Bonnyrigg, in Midlothian. Anywhere in EH23, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Gowkshill is one of 34 places we cover in Midlothian for sealant joints. Sites around Edinburgh have their own page, about 8 miles away.

Commercial sites across EH23 are covered. If your site is on The Crescent and Stobhill Road or close by, send details and we will quote for sealant joints. If your building is just outside Gowkshill, we cover Newtongrange (1 mile north), Gorebridge (1 mile south), Mayfield (1 mile north-east), Birkenside (2 miles south) and Easthouses (2 miles north). A short drive away, we cover Penicuik (7 miles west), Loanhead (4 miles west), Shawfair (5 miles north), Danderhall (4 miles north-west), Rosewell (3 miles west) and Roslin (4 miles west).

Do you need commercial sealant contractors in Gowkshill?

A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into. Getting back to a clean joint then means removing every layer.

What tends to prompt an enquiry:

  • Expansion joints with the sealant torn out
  • Leaks that seem to come through a sealant line
  • Black mould through washroom sealant that won’t clean off
  • Frame sealant that has cracked, shrunk or pulled away

If you have premises on more than one site, say at Butlerfield Industrial Estate and Mayfield Industrial Estate, one contractor and one quote can cover both.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • The named product and why it was chosen
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we are asked in Gowkshill

Is Gowkshill too far out for you?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is Butlerfield Industrial Estate, near Gowkshill, within your area?

Yes. We cover Gowkshill and the area around it, including industrial estates, business parks and retail parks such as Butlerfield Industrial Estate. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

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.

Can one contractor look after sealant on all our buildings?

Yes. Give us the sites and the scope at each, and we’ll put together a fixed quote and a sensible order of work.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Keep barriers up until the new sealant has cured
  • Keep washroom and kitchen extraction working
  • Act on the first lifting edges rather than waiting

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet. Your maintenance team can look at extract fans at the same time.

Sealant installed at the same time normally fails in sequence. A few splits this year usually mean more next year so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.

Different surfaces, different methods

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
