Sealant specialists in Upper Sanday

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. If you have damp patches where an external joint has failed and gaps behind commercial kitchen worktops and sinks, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Upper Sanday tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In an occupied building in Upper Sanday, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

In smaller Scottish places like Upper Sanday, commercial buildings are often hotels, pubs, shops, schools, surgeries and farm or estate buildings put to new use. Their kitchens, washrooms and window perimeters all need joints that keep water out.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Leave it or put it right?

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Upper Sanday before they leak.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

What the job involves on each surface

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, and we’ll tell you if the detail calls for something else.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What affects the price in Upper Sanday

Each job is priced on its own details. The main factors are:

  • The size and state of each joint
  • Removal of failed or old sealant
  • Travel to remote or island sites
  • Working within restricted access windows

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • The product your specification calls for
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • The site address and postcode

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email drawings and photos.

Frontages, fit-outs and joints in Upper Sanday

With the shore within about 1 mile, Upper Sanday counts as a coastal location. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. The east of Scotland, where Upper Sanday is, gets less rain than the west. Cold, frosty mornings and condensation on steel and glass can still delay outside work.

Where a joint is on show in Upper Sanday, we will check which shades the product offers before work starts. A lasting commercial joint around Upper Sanday begins with the old bead fully out and the faces clean and dry.

Upper Sanday is about 7 miles south-east of Kirkwall, in the Orkney Islands. We cover commercial sites throughout Upper Sanday. We work across 51 places in the Orkney Islands.

Business premises anywhere in KW17 are within our area. If your building is just outside Upper Sanday, we cover Toab (2 miles north), Tankerness (3 miles north), St Mary's (3 miles west), Burray Village (6 miles south-west) and Kirkwall (7 miles north-west). For island and remote sites, we plan travel and materials carefully, so the full address helps from the start.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Structural cracks or movement the joints weren’t designed for
  • Roof leaks that only look like a joint problem
  • Faulty windows rather than failed perimeter sealant

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.

Where we work in Upper Sanday

  • Washrooms and tea points
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • External facade joints
  • Kitchen worktops and splashbacks

Questions we are asked in Upper Sanday

Do you offer colour-matched sealant for buildings in Upper Sanday?

Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photos and we’ll confirm what’s available for the product.

Will you travel to Upper Sanday on the island?

Yes. Our area covers all of Scotland, cities, towns and islands alike, and that includes island locations such as Upper Sanday. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.

Could the old sealant in an older building contain asbestos?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you hold CHAS accreditation?

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

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How is commercial sealant work priced?

Send photographs, drawings or a list of locations through the quote form on this site. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
