Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Clear dirt from joint lines during routine cleaning
- Put movement joints on the planned maintenance inspection round
- Reopen bays and walkways only after the stated cure time
- Act on the first tear or lifting edge rather than waiting
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, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
FAQs: Castlebay
Would you work within a site like St Brendan's Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you take on a job in Castlebay, on the island?
Yes, Castlebay is within the area we cover. We cover the whole of Scotland. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
What guarantee do you give on joint sealing?
A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably, and the sealing method is much the same.
What if the joint edges are damaged?
Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first, so the new seal has something to grip.
Our process
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs near Castlebay are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Agree which areas must stay open
- Arrange parking or a loading space
Ask for a quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send details through our quote form.
Advice
Cost factors for movement joints
Before we quote, we look at:
- How accessible the joints are
- Which sealant the job calls for
- The total length or number of joints
- Induction, permit and paperwork requirements
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- What the building is and how it’s used
- Any dates the work must fit around
- Whether an asbestos survey exists
- The postcode of the building
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Leave it or put it right?
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Renewing every failing joint on one visit is the sensible approach for a place like Castlebay. Send photos and we’ll quote for everything together.
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 you’ll have a fixed figure to work with.

Expansion joint sealing around Castlebay: what changes locally
Castlebay lies within about 1 mile of the sea. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Castlebay is on Scotland’s wetter western side. External slab joints left open take plenty of rain. External sealing is booked for dry spells, with some give in the dates.
Hospital campuses such as St Brendan's Hospital (under half a mile south-west of Castlebay) grow in stages, leaving movement joints wherever new blocks meet old. Schools like Castlebay Community School often have long brick elevations with movement joints that age quietly.

What else we do in Castlebay
Different surfaces, different methods
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
