Questions about Pathhead

Is a smaller place like Pathhead outside your area?

Not at all. Pathhead is within our area. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.

Can you work at a site such as McSence Business Park, by Pathhead?

Yes. We cover Pathhead and the area around it, including industrial estates, business parks and retail parks such as McSence Business Park. To start, just give us a call on 01277 525 020 or email a schedule or drawings 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: its movement, its surfaces and what it has to cope with.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How much does the work cost?

There isn’t a price list, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

How we handle facade sealing in Pathhead

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have cladding panel joints that have opened up and unsightly perimeter sealant on a visible elevation, we can put it right. One point of contact handles commercial sealant work in Pathhead from the first photos to the final walk-round, for single jobs and planned programmes alike.

In smaller places such as Pathhead, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we’ll come back to it.

How the job changes by surface

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Joints whose design needs changing by the specifier
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If you are not sure, just phone 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Where we work in Pathhead

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

Maintenance after handover

For the best life from the joints:

  • Don’t wait for a second leak before calling
  • Record the product and colour used on each elevation
  • Never let anyone seal over old sealant
  • Plan facade sealing alongside redecoration

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.

Building owners, agents and FMs in Pathhead

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For a building near Pathhead, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Make sure the joints can be reached
  • Let us know about inductions and permits
  • Point out parking and an unloading spot

Scotland has its own building regulations, and in Pathhead warrants come from the local authority verifier. Our job is to seal to that specification.

For a contractor working at a hospital such as Midlothian Community Hospital, which lies west of Pathhead, perimeter and facade sealing is planned around patients and deliveries. When units on a site such as McSence Business Park, 2.8 miles to the west of Pathhead, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Work at a hotel such as The Stair Arms Hotel, 0.6 miles north-west of Pathhead, tends to be programmed around bookings, mastic included.
