Facade sealing across Hermiston

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Quoting for work in Hermiston

The price varies from site to site. It mainly depends on:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Which sealant the job calls for
  • How accessible the joints are

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Any specification or named product
  • Asbestos survey details if the building is older
  • When you need the work done

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call the office on 01277 525 020 or email drawings and photos.

Facade sealing in Hermiston

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve hard, chalky sealant that no longer flexes and facade joints cracked through the middle, on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters. One point of contact handles commercial sealant work in Hermiston from the first photographs to the final walk-round, whether it’s one building or several.

In smaller places such as Hermiston, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to call us in Hermiston

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.

Common reasons buildings call us in:

  • Weathered facade joints that have lost their grip
  • Cladding panel joints that have opened up
  • Water coming in around window frames
  • Unsightly perimeter sealant on a visible elevation

Further education sites such as Edinburgh College - Sighthill Campus (1.2 miles east of Hermiston) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Our contractor checklist

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Installing or repairing glazing systems

If in doubt, ring 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

  • Shopfront frames
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Cladding panel joints

Building owners, agents and FMs in Hermiston

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

FAQs: Hermiston

Is a smaller place like Hermiston outside your area?

Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you cover business parks and estates near Hermiston, such as Hermiston Gait Retail Park?

Yes, sites like Hermiston Gait Retail Park are within our area, along with the rest of Hermiston. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Different surfaces, different methods

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Building and refurbishing in Hermiston

Being in the east of Scotland, Hermiston gets less rain than the west coast. Winter mornings can still bring frost and condensation on steel and glass. External mastic is planned with the site manager for workable conditions. A number of hotels sit less than 2 miles from Hermiston. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

For contractors on a campus like Heriot-Watt University, 0.8 miles to the south of Hermiston, facade and perimeter sealing has to fit around students and term dates. Units on estates such as Hermiston Gait Retail Park, 0.6 miles north-east of Hermiston, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Hermiston is about 5 miles west of Edinburgh, in Edinburgh. Across the EH12 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Hermiston is one of 174 places we cover in Edinburgh for facade joints.

If you need facade sealing in EH12 and EH14, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. For a building on Gogar Station Road, Hermiston House Road and Hermiston Steading or nearby, we can quote for facade joints. If your building is just outside Hermiston, we cover Riccarton (1 mile south), Gogar (1 mile north-west), Maybury (1 mile north), Warriston (1 mile south-west) and West Craigs (1 mile north). Bigger towns within reach include Edinburgh (5 miles east), Leith (7 miles north-east), Bonnington (6 miles north-east), Greenside (6 miles north-east), Broughton (6 miles north-east) and Bellevue (6 miles north-east).

What’s near Hermiston

The nearest railway station is Edinburgh Park station, roughly 0.6 miles north-east. Nearby you will also find ICE Scotland Museum (0.8 miles south) and The Gyle Shopping Centre (1.2 miles north). For a walk, there’s The New Leaf Co-op and Warklaw Hill.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Hermiston, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.
