FAQs: Portsoy

Is a smaller place like Portsoy outside your area?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.

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

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

About our expansion joint sealing in Portsoy

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. The enquiries we see most involve joints packed with grit and debris and movement joints with split or torn sealant, across cladding panel joints, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Portsoy it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Portsoy is planned so the work is done in one trip where possible. Photos, approximate widths and what uses the floor help us bring the right materials.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What we’re called out for in Portsoy

When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again unless width and product are reviewed.

Site and facilities staff are often the first to spot these:

  • Weathered movement joint sealant that no longer flexes
  • Torn sealant in brick or block movement joints
  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face

In and around Portsoy, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • Health and safety accreditation such as CHAS
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Brief car park operatives to protect joint lines during winter clearance
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Inspect exposed joints once the cold weather has passed
  • Reopen bays and walkways only after the stated cure time

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, call the office on 01277 525 020 or email a schedule or drawings with photographs.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Honest limits

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

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

  • Precast concrete panel joints
  • Podiums and floor movement joints
  • Brickwork movement joints
  • Blockwork control joints
  • Cladding panel joints
  • Car park decks and ramps

Why act early in Portsoy

Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too. Where it helps, we quote both options. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Portsoy before they leak.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Expansion joint sealing around Portsoy: points for this area

Portsoy lies within about 1 mile of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. The east of Scotland, where Portsoy is, gets less rain than the west. Frost and de-icing salt still find their way into open external joints. Sealing them in drier months limits winter damage.

A healthcare site such as Campbell Hospital (to the west of Portsoy) depends on car parks, ramps and service yards whose joints take traffic all day.

Portsoy is about 10 miles east of Buckie, in Aberdeenshire. Any commercial site in Portsoy is covered, for single jobs and planned programmes alike. Portsoy is one of 179 places in Aberdeenshire on our list. Sites around Aberdeen have their own page, roughly 42 miles from Portsoy.

If you need expansion joint sealing in AB45, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. For a building on South High Street, North High Street and Main Street or nearby, send details and we will quote for movement joints. Portsoy sits on or close to the A98 and B9019, useful when we plan access and materials. Close to Portsoy, our area also takes in Sandend (2 miles west), Fordyce (2 miles south-west), Boyndie (4 miles south-east), Ladysbridge (4 miles east) and Whitehills (4 miles east).

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Induction, permit and paperwork requirements
  • The product specified
  • Any access equipment needed
  • Travel to remote or island sites

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.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • What the building is and how it’s used
  • When you need the work done
  • Anything awkward about access or site hours
  • Any specification or named product

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Tell us who will meet us and how to get in at your building near Portsoy. We will confirm the plan with the fixed quote.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Send your site hours and access windows

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
