What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. Renewing every failing joint on one visit is the sensible approach for a place like Grimsay. Send photographs and we will quote for everything together.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

About our expansion joint sealing in Grimsay
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. Most enquiries involve hardened, cracked sealant on exposed facades and arrises breaking up along floor joints, across podiums and floor movement joints, car park decks and ramps and blockwork control joints. Whoever orders the work in Grimsay, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For outside joints near Grimsay, the Scottish weather sets the timetable: dry faces and the right temperature are essential. Inside slabs aren’t affected and can be scheduled around the occupier.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

How the job changes by surface
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.
Do you need expansion joint sealing in Grimsay?
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.
What tends to prompt an enquiry:
- Arrises breaking up along floor joints
- Weathered movement joint sealant that no longer flexes
- Sealant peeling off one face of the joint
- Expansion joints filled with dirt and stones
Around Grimsay, each joint gets a filler or sealant matched to what crosses it and how much it moves.
Questions to ask before you book
- What the guarantee covers, and for how long
- The named product and why it was chosen
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Movement on a scale no sealant is meant to absorb
- Leaks coming from the membrane rather than the joint seal
- A joint that has to be widened or re-detailed before it can work
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Travel to smaller Scottish places like Grimsay is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Make sure the joints can be reached
- Point out any areas we must not close

Slabs, ramps and loading bays in Grimsay
Grimsay is within about 1 mile of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Being on an island, Grimsay means planning around ferry times as well as the weather. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.
Hospital campuses such as Uist and Barra Hospital, 5.8 miles to the north-west of Grimsay, grow in stages, leaving movement joints wherever new blocks meet old.

Maintenance after handover
Regular inspection catches problems early. Specifically:
- Record the sealant used and the date in the O&M file
- Act on the first tear or lifting edge rather than waiting
- Brief car park operatives to protect joint lines during winter clearance
- Put movement joints on the planned maintenance inspection round
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Barriers left in place until then protect the finish.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.
Questions about Grimsay
Would you work within a site like Uist and Barra Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work on the island where Grimsay is?
Yes. Islands are part of our area, Grimsay included. Island work is planned around ferry crossings and the weather, so photographs and a full list before we travel are essential.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last, and we’ll point out where that’s the case. A bead on a broken edge soon lets go.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
