Facade sealing in Arniston, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. We work on shopfront frames, stone and brick facade joints and coping and flashing joints, and what we’re called in for most is perimeter sealant that has split or peeled away and damp patches beside frames after rain. One point of contact handles commercial sealant work in Arniston from the first photographs to the final walk-round, for single jobs and planned programmes alike.

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

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When to call us in Arniston

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.

Things that normally lead to an enquiry:

  • Hard, chalky sealant that no longer flexes
  • New sealant peeling off old mastic
  • Unsightly perimeter sealant on a visible elevation
  • Perimeter joints where frames meet the structure

On a healthcare site such as Midlothian Community Hospital (3.8 miles north-west of Arniston), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Contractors’ notes for Arniston

Arniston is in the east of Scotland, which is drier than the west. Frosty spells still affect external mastic dates. We agree external dates with the site team and keep internal work ready. Building work in Arniston comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.

Historic houses such as Melville Castle, 4.7 miles north-west of Arniston, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New units and refits on sites such as Butlerfield Industrial Estate, 2.3 miles north of Arniston, need their panel and perimeter joints sealed to the specification.

Common questions from Arniston clients

Can you work at a site such as Butlerfield Industrial Estate, by Arniston?

Yes. Estates, retail parks and business parks around Arniston, Butlerfield Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Midlothian Community Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

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.

Is Arniston in your area?

Yes. Arniston is in our area. To discuss a job, give us a call on 01277 525 020 or use the quote form.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Brief window cleaners about newly sealed joints
  • Inspect facade joints on a regular cycle
  • Combine resealing with other works that need access
  • Note when each elevation was last resealed

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

What the job involves on each surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair.

Window and door perimeters

Frame materials vary, and so does the preparation. Primer goes on where the manufacturer specifies it for that substrate.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Arranging specialist high-level access, which is planned with the client
  • Cracked or spalling substrates that need repair before sealing
  • Movement beyond what any sealant can handle

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Surfaces we seal

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

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
