Expansion joint sealing for commercial buildings in North Mundham
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. We seal and reseal movement joints in walls, panels, decks and floors on sites in North Mundham. We work on cladding panel joints, car park decks and ramps and precast concrete panel joints, and the failures we are asked to look at most are movement joints with split or torn sealant and expansion joints filled with dirt and stones.

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Joints too narrow for the movement, which need redesigning by the engineer
- Cracking or settlement that calls for an engineer’s assessment
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Site staff or a sealant specialist?
Redoing a failed joint normally 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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why it’s worth doing now in North Mundham
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. Older rural buildings around North Mundham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Traffic, movement and joints around North Mundham
With the shore within about 3 miles, North Mundham counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. At about 55 miles from central London, North Mundham is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.
For an occupier at a site such as Quarry Lane Industrial Estate, 1.2 miles north of North Mundham, the joints at loading doors and dock levellers normally see the hardest wear. Schools like North Mundham Primary School often have long brick elevations with movement joints that age quietly. Large sites such as St Richard's Hospital, 2.2 miles to the north of North Mundham, have car parks, service roads and long elevations with movement joints in brick and panels.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Report split or peeling joint sealant early
- Keep product details with the building records for the next reseal
- Inspect exposed joints once the cold weather has passed
- Include every elevation and deck joint in periodic inspections
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.
Our process
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like North Mundham are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, 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.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Point out parking and an unloading spot
- Tell us what induction or permit system the site runs
- Have the specification and drawings to hand

Common questions from North Mundham clients
Is Quarry Lane Industrial Estate, near North Mundham, within your area?
Yes. Our area takes in North Mundham and its surroundings, with estates and business parks such as Quarry Lane Industrial Estate included. A few photographs and the unit address let us price the work.
Does a coastal location like North Mundham affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Which product is best for expansion joints?
Whatever suits the joint and the specification. The quote states the sealant and its movement class, so you know what’s going in.
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 external work may be moved if conditions aren’t right. Internal work is far less affected.
How long will the joint resealing take?
Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote along with the phasing plan.
What’s the difference between an expansion joint and 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, and either way it needs a sound seal.
Can a joint be sealed if the edges are broken?
Broken arrises have to be put right before resealing, and we’ll point out where that’s the case. A bead on a broken edge soon lets go.
