Expansion joint sealing in Shawbost
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. Most enquiries involve rain penetration at brick or block movement joints and leaks through car park deck joints onto the level below, across precast concrete panel joints, podiums and floor movement joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Shawbost is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Travel to smaller places like Shawbost 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.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. Where we can, we combine work around Shawbost with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- 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.
- 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.
- 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.
Getting the site ready
- Warn occupants and staff about the work
- Flag any permit to work we’ll need

Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Your questions answered
Is Shawbost inside the area you cover, given it’s on an island?
Yes. Every Scottish council area is within our area, and that includes island locations such as Shawbost. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Can being near the sea in Shawbost affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Which product is best for expansion joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- The product specified
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Asbestos survey details if the building is older
- The postcode of the building
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or send details through our quote form.

What happens if it’s left?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. For buildings near Shawbost, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Floors, slabs and movement joints in Shawbost
The sea is no more than about 2 miles from Shawbost. 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. Being in the west of Scotland, Shawbost gets more rain than eastern areas. Open joints in car parks and yards let in more water than in drier areas. External sealing is booked for dry spells, with some give in the dates.
A joint near Shawbost that has lost its sealant lets in water and grit, and the edges suffer next; we’ll tell you if the edges need repairing first. Around Shawbost, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Keep scrapers and ploughs from dragging across joint sealant
- Keep racking legs and heavy point loads off floor joints
- Act on the first tear or lifting edge rather than waiting
- Keep stones and debris out of open joint lines
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.
