Facade sealing for Cousland sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Travel to smaller Scottish places like Cousland is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Point out parking and an unloading spot
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Advice

Facade sealing in Cousland

We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. The enquiries we see most involve weathered joints at frame-to-structure perimeters and cold air coming in at window perimeters, across window and door perimeters, shopfront frames and coping and flashing joints. A single leaking joint is often how a building in Cousland first comes to us: we look at the rest while we are there and tell you what we find.

Sites near smaller places like Cousland can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Looking after the joints

To get the most from the new sealant:

  • Keep sills, gutters and drainage paths clear
  • Confirm the survey covers external sealants in older buildings
  • Avoid patch repairs on failed facade joints
  • Share access with other external trades

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What the job involves on each surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification.

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod.

When to call us in Cousland

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Look out for the following:

  • Weathered facade joints that have lost their grip
  • Gaps between rainscreen or cladding panels
  • Weathered joints at frame-to-structure perimeters
  • Sealant pulling away from frames or panels

Units on estates such as Wallyford Industrial Estate (2.2 miles north of Cousland) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Cousland, a repair visit takes planning, so it’s better to act early.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Why appoint us

  • Standard and matched colours in many product ranges
  • Sealing commercial buildings since 2005
  • Work carried out by CSCS-carded applicators
  • Public liability insurance in place

Contractors’ notes for Cousland

The east of Scotland, where Cousland is, gets less rain than the west. Cold, damp starts still stop external sealing on some days. We agree external dates with the site team and keep internal work ready. There are several hotels within about 2 miles of Cousland. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Building work at universities like Queen Margaret University, 3.4 miles to the north-west of Cousland, is often timed for the summer, mastic included. Hospital estates such as Midlothian Community Hospital (to the south-west of Cousland) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Cousland is about 3 miles east of Dalkeith, in Midlothian. Commercial clients in Cousland can call on us for facade joints. We work across 34 places in Midlothian, large and small. Edinburgh is covered too, some 8 miles away.

Cousland: questions and answers

Is Cousland too small for you to travel to?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.

Can you work on a hospital site such as Midlothian Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you take on multi-site work?

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

What will the job cost?

Each job is quoted on its own details. For yours, call the office on 01277 525 020 or email us with a description of the work.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we will plan the work with you.
