Why it’s worth doing now in Gayfield

A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. Getting access arranged for a building in Gayfield takes time, so it makes sense to renew every failing joint while it’s in place.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why clients in Gayfield choose us

  • A range of standard colours, depending on the product

About our construction mastic in Gayfield

Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. If you have perimeter gaps outside the sealant’s range and a mastic package split between trades with no clear owner, we can help. A single leaking joint is often how a building in Gayfield first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Construction in Scotland’s cities is a mix of new build and work to existing stone buildings. Building warrants and the Scottish technical handbooks set the standard, and the mastic follows the specification.

A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

When to call us in Gayfield

Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is normally the first to crack. Choosing the right product for each joint reduces that.

What tends to prompt an enquiry:

  • Mastic snags holding up handover
  • Sanitary sealant damaged by following trades
  • Perimeter gaps outside the sealant’s range
  • Cracks opening in caulked internal joints

University estates such as University of Edinburgh - Holyrood Campus, 0.7 miles to the south of Gayfield, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Questions to ask before you appoint anyone

What the job involves on each surface

Internal decorators’ caulk

Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.

Sites and facades in and around Gayfield

Gayfield lies within about 1 mile of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. There are a good number of hotels within about 2 miles of Gayfield. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

When units on a site such as Beaverbank Business Park, 0.5 miles north-west of Gayfield, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotels like Cairn Hotel, less than half a mile east of Gayfield, rarely close for long, so refurbishment mastic is phased floor by floor.

Gayfield is about 1 mile north-east of Edinburgh, in Edinburgh. We cover commercial sites throughout Gayfield, whether it’s a single job or part of a planned programme. Gayfield is one of 174 places in Edinburgh on our list for mastic packages.

Anyone looking for construction mastic in EH7, EH1 and EH3 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on York Lane, Meuse Lane and Albany Lane or close by, send details and we’ll quote for mastic packages.

Questions we are asked in Gayfield

Will you plan work around the academic year at somewhere like University of Edinburgh - Holyrood Campus?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can being near the sea in Gayfield affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

What does a mastic package normally include?

External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

What guarantee comes with a mastic package?

It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Can fire-rated sealing at service penetrations be included?

We install fire-rated sealant where it is the specified product to the tested detail. If the detail calls for collars, wraps or batts instead, we’ll tell you.

Aftercare for building managers

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

  • Get the mastic subcontractor involved early in the programme
  • Ask installers to correct oversized gaps first
  • Don’t schedule sealing before decorators and flooring are done
  • Note which sealant went where at handover

Record which products went where in the handover file. Future maintenance is easier when the products are known. Tell us what records you need and we’ll confirm with the quote.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. For premises in Gayfield, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows
  • Point out parking and an unloading spot
