Where floor joints take the most wear near North Street
With the shore within about 1 mile, North Street counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Rainfall across the South East, North Street included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
University campuses such as University of Greenwich - Medway, 4 miles to the south-west of North Street, have car parks, paved walkways and building elevations with movement joints. Sites like Medway Maritime Hospital, 4.9 miles south-west of North Street, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

How we handle expansion joint sealing in North Street
If you need expansion joint sealing in North Street, start with photos and joint lengths. We will come and look where photos don’t show enough, then send a fixed quote that names the sealant. To discuss the joints first, ring 01277 525 020 or email a schedule or drawings. Most enquiries involve previous reseals laid over old sealant and chipped joint edges on forklift routes, across car park decks and ramps, blockwork control joints and precast concrete panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in North Street is the same: the right product in a properly prepared joint.
Smaller community and commercial buildings around North Street have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
A 12-month guarantee applies to all our work in Medway. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we’ll come back to it.

Leave it or put it right?
Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Around North Street, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like North Street are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
Before we start on site
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached

What else we do in North Street
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Proprietary pre-formed expansion joint systems
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Waterproofing layers buried beneath the sealant
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Blockwork control joints
- Precast concrete panel joints
- Brickwork movement joints
- Podiums and floor movement joints
- Cladding panel joints
- Car park decks and ramps
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Check joints after long freezing spells
- Raise snow-clearing blades over deck joints where possible
- Clear dirt from joint lines during routine cleaning
- Leave barriers in place until fresh joint sealant has cured
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
Common questions from North Street clients
Does the sea air around North Street change the choice of 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.
Is a smaller place like North Street outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you seal car park deck joints?
Yes. Tell us how the car park is used and which areas must stay open and we will plan around them.
What timescale should we allow for resealing expansion joints?
It usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.
Cost factors for movement joints
These are the things that shape the price:
- The size and state of each joint
- Working within restricted access windows
- Induction, permit and paperwork requirements
- The total length or number of joints
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.

A few photographs plus some basic facts will normally do. Please tell us:
