Facade sealing in Clo Mhuillin: the local picture

The sea is no more than about 1 mile from Clo Mhuillin. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. A 2-mile radius around Clo Mhuillin takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

A facade joint near Clo Mhuillin lasts when width, depth and backing are right, not just the finish.

Facade sealing in Clo Mhuillin, done properly

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. Most enquiries involve unsightly perimeter sealant on a visible elevation and patch repairs that keep failing, across stone and brick facade joints, perimeter joints where frames meet the structure and window and door perimeters. Looking for mastic applicators who cover Clo Mhuillin? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

External sealing around Clo Mhuillin depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or use the quote form and we’ll arrange a return visit.

When to call us in Clo Mhuillin

Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.

What tends to prompt an enquiry:

  • New sealant peeling off old mastic
  • Cladding panel joints that have opened up
  • Damp patches beside frames after rain
  • Unsightly perimeter sealant on a visible elevation

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

What your quote should include

  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?
  • Their pre-qualification and accreditations
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. 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. Jobs near Clo Mhuillin are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Advice

Cost factors for facade joints

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • How much existing material needs removing
  • The total length or number of joints
  • The site’s rules and procedures

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Clear photographs of the problem areas
  • The asbestos register, for older buildings
  • Access details, including height
  • When you need the work done

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or email us.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign
  • Specialist high-level access methods

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Joints and surfaces we work on

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

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Keep sills, gutters and drainage paths clear
  • Note when each elevation was last resealed
  • Insist on a full cut-out when joints are renewed
  • Combine resealing with other works that need access

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

Site staff or a sealant specialist?

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 where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we are asked in Clo Mhuillin

Is a smaller place like Clo Mhuillin outside your area?

Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Does the sea air around Clo Mhuillin change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can you just add new sealant on top?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Can you find out why a window is leaking?

Yes. Photos help, and you can give us a call on 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all.
