When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Proprietary pre-formed expansion joint systems
- Movement on a scale no sealant is meant to absorb
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.
Where we work in Darnick

Expansion joint sealing in Darnick, done properly
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. The enquiries we see most involve water dripping through deck or ramp joints and torn sealant in brick or block movement joints, on cladding panel joints, car park decks and ramps and precast concrete panel joints. A specialist sealant contractor works differently from a general builder: in Darnick, that means joint design, primers and backing rod as standard.
Travel to smaller places like Darnick 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.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What sets the cost
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- How much existing material needs removing
- Location, for remote and island sites
- Access and working height
There’s no price list, since every building and every scope is different. Call for a quote.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
- The product your specification calls for
- The type of building and who uses it
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or send photos by email.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Darnick: questions and answers
Would you work within a site like Borders General Hospital?
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.
Is Tweedbank Industrial Estate, near Darnick, within your area?
Yes. We cover Darnick and the area around it, including industrial estates, business parks and retail parks such as Tweedbank Industrial Estate. Photos and a short description are enough for a first look.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
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, so we’ll confirm the curing time on the day.
Does the weather affect joint sealing?
Sealing onto a damp surface leads to adhesion failure. We agree a revised date with you.
Leave it or put it right?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. For buildings near Darnick, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Darnick has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Phasing is what makes joint work possible on busy sites such as Borders Innovation Park (0.6 miles north-west of Darnick): one bay, aisle or car park row at a time. University campuses such as Heriot-Watt University - Scottish Borders Campus (to the west of Darnick) have car parks, paved walkways and building elevations with movement joints. Hospitals like Borders General Hospital (to the south of Darnick) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Darnick are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work
