Need expansion joint sealing in Unthank?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle expansion joint sealing in Unthank

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on blockwork control joints, precast concrete panel joints and brickwork movement joints, and the usual reasons a site gets in touch are layers of sealant in a movement joint and expansion joints split through the centre of the bead. Whoever orders the work in Unthank, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller Scottish places like Unthank, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Slabs and yards take vehicles, rain and frost.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Unthank

Is a smaller place like Unthank outside your area?

No. Places such as Unthank are covered as much as the big towns. We cover the whole of Scotland. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

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

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can the building stay open while you work?

In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Does the weather affect joint sealing?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • Phasing around occupants
  • Any access equipment needed
  • Backing rod, priming and other preparation
  • The total length or number of joints

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

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

  • What the building is and how it’s used
  • When you need the work done
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email drawings and photos.

Commercial clients in Unthank

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Unthank can form part of a wider programme.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Unthank. Several sites can go on one quote, which keeps the paperwork simple.

Expansion joint sealing around Unthank: how the place shapes the job

Being in the east of Scotland, Unthank gets less rain than the west coast. Frost and winter road salt still work into open joints in car parks and yards. Sealing them in drier months limits winter damage.

For an estate such as Stracathro Hospital, which lies north-east of Unthank, the joints in ramps, decks and long building elevations all need attention over time. In a school such as Brechin High School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Office parks like Brechin Business Park, 1.2 miles south-west of Unthank, have decks, ramps and clad elevations whose joints take movement every day.

Unthank is about 7 miles west of Montrose, in Angus. Our applicators travel to Unthank for work on movement joints. We work across 65 places in Angus. There’s a separate page for Dundee, about 22 miles away.

Commercial sites across DD9 are covered. If your site is on Trinity Road, Eddie Avenue and Cookston Road or close by, send details and we will quote for movement joints. If your building is just outside Unthank, we cover Brechin (1 mile south), Little Brechin (2 miles north-west), Edzell (5 miles north), Edzell Woods (5 miles north) and Craigo (6 miles east). Further afield, our area takes in Arbroath (13 miles south), Forfar (11 miles south-west), Montrose (7 miles east), Kirriemuir (14 miles west), Letham (9 miles south-west) and Hillside (7 miles east).

What’s near Unthank

Around Unthank, our work takes us to commercial buildings near City Road Bar and Brechin Public Park, among other places. Well-known places in the area include Brechin Castle (0.9 miles south) and Brechin Town House Museum (0.7 miles south). For a walk, there’s Caterthun and Duns Dish.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Tell us who will meet us and how to get in at your building near Unthank. That goes into the plan alongside the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need

Quotes

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Advice

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Report split or peeling joint sealant early
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Look over external and deck joints after a hard winter
  • Keep product details with the building records for the next reseal

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • A joint that has to be widened or re-detailed before it can work
  • Damaged metal nosings or cover plates over a joint
  • Leaks coming from the membrane rather than the joint seal

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Joints and surfaces we work on

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

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
