Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Expansion joint sealing for commercial buildings in Sharnal Street
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. We work on podiums and floor movement joints, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are brittle, chalky sealant on external joints and leaks through car park deck joints onto the level below. Most enquiries from Sharnal Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Sharnal Street, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
How a job runs
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

Advice
Warehouse floors and decks around Sharnal Street
Sharnal Street lies within about 2 miles of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
In a school such as High Halstow Primary Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak. Campuses like University of Greenwich - Medway (to the south-west of Sharnal Street) mix old and new buildings, with movement joints wherever they meet. For an estate such as Medway Maritime Hospital, which lies south of Sharnal Street, the joints in ramps, decks and long building elevations all need attention over time.

Why it’s worth doing now in Sharnal Street
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Converted and older buildings near places like Sharnal Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Questions we are asked in Sharnal Street
Is Sharnal Street off your patch?
Not at all. Sharnal Street is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Our building in Sharnal Street is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Which product is best for expansion joints?
The right product depends on the joint. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- A joint that has to be widened or re-detailed before it can work
- Movement on a scale no sealant is meant to absorb
- Waterproofing layers buried beneath the sealant
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Car park decks and ramps
- Blockwork control joints
- Cladding panel joints
- Precast concrete panel joints
- Podiums and floor movement joints
Keeping the joints sound
To get the most from the new sealant:
- Keep stones and debris out of open joint lines
- Put movement joints on the planned maintenance inspection round
- Report split or peeling joint sealant early
- Avoid parking heavy plant or pallets on joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can phone 01277 525 020 or email drawings and photos and send a picture.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
