Expansion joint sealing in Hartlip
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Most enquiries involve car park joints leaking onto vehicles below and new sealant over old, now failing, on precast concrete panel joints, brickwork movement joints and podiums and floor movement joints. Whoever orders the work in Hartlip, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller community and commercial buildings around Hartlip have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Signs you need expansion joint sealing in Hartlip
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Site and facilities staff are often the first to spot these:
- Layers of sealant in a movement joint
- Brittle, chalky sealant on external joints
- Spalled or broken joint edges in floors and decks
- Rain penetration at brick or block movement joints
Sites like Medway Maritime Hospital, 4.8 miles to the north-west of Hartlip, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Jobs in and around smaller places like Hartlip are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Flag any permit to work we will need

Advice
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Hartlip. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. 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.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Slabs, ramps and loading bays in Hartlip
Hartlip sits close to the coast, within about 3 miles. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. At least three named trading, business or retail sites lie within about 3 miles of Hartlip. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Another example is Newington Enterprise Centre, 1.6 miles north-east of Hartlip, where floors and yards would be done in stages around the occupiers. Schools like Hartlip Endowed Church of England Primary School often have long brick elevations with movement joints that age quietly.

Why deal with it now?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too. We can price a patch and a full reseal side by side. Older rural buildings around Hartlip move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Your questions answered
Can being near the sea in Hartlip affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Is a hospital such as Medway Maritime Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long does movement joint sealing take?
It typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote, including any phasing.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
How much does the work cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
