How we handle facade sealing in Howgate

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, but not always. If the evidence points away from the sealant, we say so before quoting. Most enquiries involve staining on stone next to old sealant and failed seals around shopfront and entrance frames, across cladding panel joints, window and door perimeters and stone and brick facade joints. A single leaking joint is often how a building in Howgate first comes to us: we look at the rest while we are there and tell you what we find.

Sites near smaller places like Howgate can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Quoting for work in Howgate

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Distance, for remote addresses
  • Whether the work must be split into stages

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any specification or named product
  • Your programme or deadline
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Your questions answered

Is Howgate off your patch?

No. Places such as Howgate are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like University of Edinburgh - Easter Bush Campus for the vacation?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

Can you work on upper floors?

That comes down to the access arranged for the job. When you speak to us on 01277 525 020 or email us, describe the access, and we’ll plan the work with you.

Looking after the joints

A few simple habits keep the new joints working:

  • Clear debris that holds water against joints
  • Keep the sealant details on the building file
  • Investigate damp beside windows promptly
  • Never let anyone seal over old sealant

After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Facade sealing around Howgate: points for this area

A number of hotels sit less than 2 miles from Howgate. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Howgate is on Scotland’s drier eastern side. Frosty spells still affect external mastic dates. External mastic is planned with the site manager for workable conditions.

For a contractor at a hotel such as The Royal Hotel, 1.3 miles to the north-west of Howgate, the mastic often has to be finished before a reopening date. School extensions, at buildings such as Wellington School, typically run to the summer holidays, mastic included. For contractors refurbishing units at places like Eastfield Industrial Estate, 1.8 miles north of Howgate, the mastic covers cladding panels, roller-door and window perimeters.

Howgate is about 2 miles south-east of Penicuik, in Midlothian. Looking for facade sealing in Howgate? We can help, as we do across Midlothian. Howgate is one of 34 places we cover in Midlothian for facade joints. Edinburgh is covered too, around 9 miles from Howgate.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For work around Howgate, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  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. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Send your site hours and access windows

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Render or concrete edges that have broken away
  • Work on the window or framing system itself
  • Arranging specialist high-level access, which is planned with the client

If in doubt, call 01277 525 020 or email us and we’ll say what we think.

Where we work in Howgate

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

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Howgate. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Why it’s worth doing now in Howgate

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
