How we handle expansion joint sealing in Hither Green
Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. The enquiries we see most involve debris jammed in movement joints and hardened, cracked sealant on exposed facades, on car park decks and ramps, blockwork control joints and precast concrete panel joints. For commercial sealant work in Hither Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Damaged metal nosings or cover plates over a joint
- Concrete or masonry repairs along the arrises
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Hither Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Let us know about inductions and permits
- Move anything stored against the joints
- Send any specification or drawings in advance

Your questions answered
Can you work on a hospital site such as University Hospital Lewisham?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are expansion joints and movement joints the same thing?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.
Can you seal car park deck joints?
Yes. Tell us how the car park is used and which areas must stay open.
Do you guarantee expansion joint work?
The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.
Surface by surface
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Avoid parking heavy plant or pallets on joint lines
- Raise snow-clearing blades over deck joints where possible
- Act on the first tear or lifting edge rather than waiting
- Look over external and deck joints after a hard winter
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Common problems we fix in Hither Green
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
It’s worth sending us details if you spot any of the following:
- Car park joints leaking onto vehicles below
- Layers of sealant in a movement joint
- Rain penetration at brick or block movement joints
- Joints where the bead has lost adhesion
A healthcare site such as University Hospital Lewisham, 0.8 miles to the west of Hither Green, depends on car parks, ramps and service yards whose joints take traffic all day.
