Facade sealing in Grindiscol

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. We work on stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are weathered facade joints that have lost their grip and sealant pulling away from frames or panels. One point of contact handles commercial sealant work in Grindiscol from the first photos to the final walk-round, whether it’s one building or several.

Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Grindiscol that means watching the forecast. We build some give into the plan and agree it with the site manager.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, and mask the edges carefully.

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 with backing and a facade-grade sealant.

Honest limits

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

  • Installing or repairing glazing systems
  • Joints too narrow for the movement they take, which need redesign
  • Providing access systems for the work

Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.

What we seal

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

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building near Grindiscol, directions, keys and a contact on the day are worth sorting early. We’ll confirm the plan with the fixed quote.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  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. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

Advice

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

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, with each stage agreed with your site contact.

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Grindiscol before they leak.

Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Keep pressure washers away from fresh sealant
  • Keep sills, gutters and drainage paths clear
  • Share access with other external trades
  • Record the product and colour used on each elevation

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Building and refurbishing in Grindiscol

Grindiscol lies within about 1 mile of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Grindiscol has several hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

For contractors refurbishing units at places like North Ness Business Park, which lies north-west of Grindiscol, the mastic covers cladding panels, roller-door and window perimeters. Work at a hotel such as Kveldsro House Hotel, 1.1 miles to the north-west of Grindiscol, tends to be programmed around bookings, mastic included. New wings at hospitals like Montfield Hospital, 1.6 miles north-west of Grindiscol, bring long runs of window and panel joints to seal.

Common questions from Grindiscol clients

Is hospital work, at somewhere like Montfield Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you take on a job in Grindiscol, on the island?

Yes, Grindiscol is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

How much does the work cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

How long does a job like this take?

It depends on the scope, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Which sealant will you use?

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.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.
