Facade sealing across Strachan

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Strachan can form part of a wider programme across Aberdeenshire.

Facade sealing in Strachan

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. Most enquiries involve failed sealant on precast panel joints and water coming in around window frames, across perimeter joints where frames meet the structure, window and door perimeters and shopfront frames. A single leaking joint is often how a building in Strachan 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.

For a site around Strachan, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Travel to smaller Scottish places like Strachan is planned so the job is finished in one visit where possible, 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. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  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. We go over the completed work with you before leaving.

Before we start on site

  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use
  • Send any specification or drawings in advance

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Advice

Questions about Strachan

Is Strachan off your patch?

No. Small places get the same service as large ones. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Glen O'Dee Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

Do you replace failed glazing units?

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

What the job involves on each surface

Precast concrete panels

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

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

What we are called out for in Strachan

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

It’s worth sending us details if you spot any of the following:

  • Discoloured or dirty facade joints
  • Damp patches beside frames after rain
  • Patch repairs that keep failing
  • Hard, chalky sealant that no longer flexes

For contractors building in or near Strachan, we seal to the drawings, the specification and the programme.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • Proof of insurance

Facade sealing around Strachan: how the place shapes the job

The east of Scotland, where Strachan is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We programme around it with the site team. Scotland has its own building regulations, and in Strachan warrants come from the local authority verifier. Our job is to seal to that specification.

Extensions at sites like Glen O'Dee Hospital, 2.8 miles to the north of Strachan, normally sit beside working departments, and the mastic follows strict access rules.

Strachan is about 18 miles south-west of Aberdeen, in Aberdeenshire. Businesses, contractors and managing agents in Strachan use us for work on facade joints. Strachan is one of 179 places we cover in Aberdeenshire. Aberdeen is covered too, some 18 miles away.

Business premises anywhere in AB31 are within our area. For a building on Bowbutts Brae and Feugh View or nearby, send details and we will quote for facade joints. Sites close to Strachan are covered too, including Banchory (3 miles north-east), Inchmarlo (3 miles north), Crossroads (5 miles east), Crathes (5 miles north-east) and Potarch (5 miles north-west).

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Render or concrete edges that have broken away
  • Providing access systems for the work
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

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

Joints and surfaces we work on

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

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
