Expansion joint sealing in Seton
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What affects the price in Seton
These are the things that shape the price:
- Location, for remote and island sites
- Whether the work must be split into stages
- Any access equipment needed
- Removal of failed or old sealant
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The site address and postcode
- Photos of the joints, close up and from further back
- Your programme or deadline
- How the joints are reached, and at what height
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email the details over.

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Changing the joint layout or spacing of a structure
- Cracking or settlement that calls for an engineer’s assessment
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

Seton: questions and answers
Our building in Seton is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Is Seton too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. Where we can, we group nearby jobs to make the most of each trip.
Do you reseal car park expansion joints?
Yes. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.
Do you use silicone or polyurethane in movement joints?
The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote so there are no surprises.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What causes movement joint sealant to fail?
The way it has failed usually tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Expansion joint sealing around Seton: points for this area
Seton lies within about 1 mile of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Less than 3 miles from Seton there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Large sites such as Roodlands General Hospital (to the east of Seton) have car parks, service roads and long elevations with movement joints in brick and panels. Warehouse floors on estates like Whin Park Industrial Estate, 1.2 miles to the north-west of Seton, carry pallet trucks and forklifts over every saw-cut joint. Schools such as Ross High School have movement joints in their walls and floors that are easy to overlook.
Seton is about 4 miles east of Musselburgh, in East Lothian. Commercial clients in Seton can call on us for movement joints, as part of our coverage of East Lothian. Across East Lothian, 48 places are covered, including Seton. Our Edinburgh page has more on work in that area, about 10 miles away.

Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
What the job involves on each surface
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Cladding panel joints
We confirm what access is in place before pricing. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep traffic off new joints until the cure time is up
- Note which joints were done, when, and with what
- Brief car park operatives to protect joint lines during winter clearance
- Keep racking legs and heavy point loads off floor joints
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Where we can, we combine work around Seton with other jobs nearby. Tell us how flexible your dates are.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Confirm the product named in the specification
- Let building users know which areas are affected
