Expansion joint sealing in Portslade
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. If you are dealing with damp inside where a wall movement joint has failed and chipped joint edges on forklift routes, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Portslade, that means joint design, primers and backing rod as standard.
In a smaller place such as Portslade, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Clear dirt from joint lines during routine cleaning
- Reopen bays and walkways only after the stated cure time
- Brief car park operatives to protect joint lines during winter clearance
- Keep product details with the building records for the next reseal
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We will tell you which movement joints need doing now and which can wait.

Building owners, agents and FMs in Portslade
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Site staff or a sealant specialist?
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.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Proprietary pre-formed expansion joint systems
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Broken or spalled joint edges, which need repairing before any sealant goes in
If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work 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 our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Portslade need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.

Advice
Expansion joint sealing around Portslade: how the place shapes the job
Portslade 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, and edges left open tend to break up faster. Central London is about 46 miles from Portslade. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.
Across sites such as Portland Road Trading Estate, 0.9 miles to the south-east of Portslade, floor and movement joints can be sealed in phases so units keep working. For a centre such as Goldstone Retail Park, 1.9 miles east of Portslade, the service yard and car park joints normally need attention first.

Common questions from Portslade clients
Is Portslade too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Our building in Portslade is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How long will the joint resealing take?
Allow anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote, including any phasing.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
What we are called out for in Portslade
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it.
Typical triggers for a call:
- Hardened, cracked sealant on exposed facades
- Previous reseals laid over old sealant
- Expansion joints split through the centre of the bead
- Debris jammed in movement joints
A campus such as University of Brighton Moulesecoomb Campus, 4.2 miles to the east of Portslade, has long runs of movement joint in its buildings, decks and paving.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- What site paperwork they can supply
- Whether their applicators hold CSCS cards
- Can the work be phased to keep areas open?
