Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Greenigoe, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- Flag any permit to work we’ll need
- For older buildings, check the asbestos register before work

Expansion joint sealing in Greenigoe, done properly
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Greenigoe. If you have layers of sealant in a movement joint and rain penetration at brick or block movement joints, we can help. Most enquiries from Greenigoe start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For floor or movement joints around smaller places like Greenigoe, we plan to finish in one visit where we can. Send photographs, joint widths and details of the traffic first.
Our workmanship is guaranteed for 12 months, in Greenigoe as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?
Redoing a failed joint usually 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Different surfaces, different methods
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 and check the edges for soundness as we go.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Leave it or put it right?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Traffic, movement and joints around Greenigoe
The sea is no more than about 1 mile from Greenigoe. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. For an island location such as Greenigoe, work is planned around ferry crossings and the weather. Joint widths, lengths and the traffic over them help us bring the right fillers and sealants.
Large sites such as Balfour Hospital (2.4 miles north-east of Greenigoe) have car parks, service roads and long elevations with movement joints in brick and panels.
Greenigoe is about 3 miles south-west of Kirkwall, in the Orkney Islands. We cover commercial sites throughout Greenigoe, for single jobs and planned programmes alike. 51 places across the Orkney Islands fall within our area, Greenigoe among them.

Just outside Greenigoe, we also work in Blackhill (2 miles north), Kirkwall (3 miles north-east), Kirbister (3 miles west), Grimbister (4 miles north-west) and Orphir (5 miles west).

Greenigoe: questions and answers
Can being near the sea in Greenigoe affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Is a hospital such as Balfour Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What timescale should we allow for resealing expansion joints?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Common problems we fix in Greenigoe
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
If one of these sounds familiar, it’s time for a closer look:
- Layers of sealant in a movement joint
- Water getting into the wall through a failed joint
- Weathered movement joint sealant that no longer flexes
- Debris jammed in movement joints
Around Greenigoe, each joint gets a filler or sealant matched to what crosses it and how much it moves.
