Facade sealing in Walls, done properly

Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on shopfront frames, coping and flashing joints and window and door perimeters, and what we’re called in for most is draughts around frames and panels and sealant pulling away from frames or panels. A single leaking joint is often how a building in Walls first comes to us: we look at the rest while we’re there and tell you what we find.

External sealing around Walls depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Signs you need facade sealing in Walls

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

These are often picked up first by site or facilities staff:

  • Previous reseals run over old sealant
  • Failed seals around shopfront and entrance frames
  • Gaps between rainscreen or cladding panels
  • Unsightly perimeter sealant on a visible elevation

Around Walls, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?
  • The named product and why it was chosen

How to choose a sealant contractor

Questions about Walls

Will you travel to Walls on the island?

Yes. We cover the whole of Scotland, and that includes island locations such as Walls. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Does a coastal location like Walls affect which sealant is used?

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.

Can the building stay open while you work?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Do you replace windows or glass?

No. That work needs a glazing specialist. What we seal are the joints around frames and panels.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Contractors’ notes for Walls

Walls sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Walls is in the east of Scotland, which is drier than the west. Cold, damp starts still stop external sealing on some days. We programme around it with the site team.

On any site in or around Walls, the mastic follows the specification and the programme.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Walls, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Commercial clients in Walls

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, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Walls before they leak.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

Why us?

  • Fully insured, including public liability cover
  • One phone line for London, the South East and Scotland
  • Work carried out by CSCS-carded applicators
  • Colour options checked against the specified product

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Providing access systems for the work
  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
