How we handle expansion joint sealing in Lochmaddy
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Lochmaddy. Most enquiries involve torn sealant in brick or block movement joints and new sealant over old, now failing, on podiums and floor movement joints, brickwork movement joints and cladding panel joints. A single leaking joint is often how a building in Lochmaddy first comes to us: we look at the rest while we are there and tell you what we find.
For outside joints near Lochmaddy, the Scottish weather sets the timetable: dry faces and the right temperature are essential. Internal floors can be done whenever suits the site.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Floors, slabs and movement joints in Lochmaddy
With the shore within about 1 mile, Lochmaddy counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Being in the west of Scotland, Lochmaddy gets more rain than eastern areas. Open joints in car parks and yards let in more water than in drier areas. Outside joints are sealed in dry spells, so dates have some give.
For floors and slabs around Lochmaddy, the product is chosen for the traffic and the movement at each joint.

Different surfaces, different methods
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement flagging broken arrises before sealing.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Signs you need expansion joint sealing in Lochmaddy
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.
Most enquiries start with something like this:
- Chipped joint edges on forklift routes
- Joints packed with grit and debris
- Leaks through car park deck joints onto the level below
- Water getting into the wall through a failed joint
Around Lochmaddy, open joints collect water and debris, and the arrises are the next to go; we’ll tell you if the edges need repairing first.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
- Their approach to joint depth and backing
What sets the cost
What shapes the price:
- The product specified
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- Whether the work must be split into stages
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
However big the job, the same details help:
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
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.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us.

- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.

Advice
Why act early in Lochmaddy
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. Where it helps, we quote both options. Around smaller places like Lochmaddy, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Early resealing prevents it.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Lochmaddy: questions and answers
Do you work on the island where Lochmaddy is?
Yes. Islands are part of our area, Lochmaddy included. Ferry times and the weather set the plan, so we ask for photos and a full list first.
Does the sea air around Lochmaddy change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
What exactly is a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. The quote states the sealant and its movement class.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. 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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
