Facade sealing for businesses in Deanston

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When to call us in Deanston

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

What tends to prompt an enquiry:

  • Hard, chalky sealant that no longer flexes
  • Perimeter joints where frames meet the structure
  • Facade joints cracked through the middle
  • Patch repairs that keep failing

Hotel extensions and refits, at places such as Highland Hotel, 1 mile east of Deanston, usually run between busy periods, so the sealing is squeezed into short windows.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Whether primer will be used where the manufacturer specifies it
  • What level of public liability insurance do they hold?
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

Facade sealing for commercial buildings in Deanston

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and failed sealant on precast panel joints, on stone and brick facade joints, window and door perimeters and coping and flashing joints. Most enquiries from Deanston start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Construction around smaller Scottish places like Deanston is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

Your questions answered

Will you fit the mastic around our build programme in Deanston?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is a smaller place like Deanston outside your area?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it.

When to bring in a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs near Deanston 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. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Deanston can form part of a wider programme across Stirling.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Why act early in Deanston

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Renewing every failing joint on one visit is the sensible approach for a place like Deanston. Photos of each area help us quote the whole job.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

  • CSCS-carded applicators
  • Fixed quotes based on photographs, drawings or a visit
  • Colours confirmed for the specified product
  • Old sealant cut out, never sealed over
