Slabs, ramps and loading bays in Thurso
Thurso sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Thurso is in the east of Scotland, which is drier than the west. Frost and winter road salt still work into open joints in car parks and yards. Sealing them before winter limits the damage.
In a school such as Thurso High School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Expansion joint sealing in Thurso, done properly
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on car park decks and ramps, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are joints packed with grit and debris and brittle, chalky sealant on external joints. Facilities teams, main contractors and managing agents in Thurso tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Schools, health centres and council buildings in towns like Thurso have long runs of brick and panel movement joints. Renewing them before they leak protects the structure behind.
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’re upfront about that.

When to call us in Thurso
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
Site and facilities staff are often the first to spot these:
- Water dripping through deck or ramp joints
- Joints where the bead has lost adhesion
- Spalled or broken joint edges in floors and decks
- Water getting into the wall through a failed joint
Sites like Dunbar Hospital, 0.8 miles south-west of Thurso, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- How much there is to seal
- Any access equipment needed
- Joint width, depth and condition
- Whether old sealant has to be cut out first
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- How the joints are reached, and at what height
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email us.
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 before we move to the next. Industrial estates and retail parks around towns like Thurso usually have yard space and site rules. Town-centre premises may need parking planned.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Tell staff and tenants when we will be in
- Send any specification or drawings in advance
- Let us know about inductions and permits

Why act early in Thurso
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we’ll plan around it. In Thurso, rain and frost work into any failed joint, so small failures grow. Resealing early keeps it a simple job.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Thurso: questions and answers
Will our site in Thurso have to close for joint sealing?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.
Our building in Thurso is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Are you insured?
Yes. We’re fully insured, including public liability cover.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
