Expansion joint sealing across Hackington

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle expansion joint sealing in Hackington

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. Site teams most often ask us about movement joints with split or torn sealant and hardened, cracked sealant on exposed facades, on brickwork movement joints, blockwork control joints and podiums and floor movement joints. Whoever orders the work in Hackington, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Jobs around smaller places like Hackington are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

After the work

To get the most from the new sealant:

  • Plan racking layouts so feet don’t land on a joint
  • Leave barriers in place until fresh joint sealant has cured
  • Check joints after long freezing spells
  • Act on the first tear or lifting edge rather than waiting

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can call 01277 525 020 or send photos by email and send a picture.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. Keeping the seal sound avoids all of that.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Hackington need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we will need
  • Tell staff and tenants when we will be in

Quotes

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Related advice

When to call us in Hackington

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

What tends to prompt an enquiry:

  • Joints packed with grit and debris
  • Car park joints leaking onto vehicles below
  • Water getting into the wall through a failed joint
  • Torn sealant in brick or block movement joints

At places like Canterbury Retail Park, 1.5 miles to the south-east of Hackington, joints are sealed a section at a time so operations carry on.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • How joint depth will be controlled
  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Joints that move: notes for Hackington

Hackington lies roughly 52 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Hackington is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

For estates staff at a university like University of Kent, 0.8 miles south-west of Hackington, building and paving joints are part of the planned maintenance list. For an estate such as Saint Martin's Hospital (2.4 miles south-east of Hackington), the joints in ramps, decks and long building elevations all need attention over time.

Hackington is about 2 miles north of Canterbury, in Kent. Anywhere in CT2, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent, large and small. There’s a separate page for London, about 52 miles away.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Changing the joint layout or spacing of a structure
  • Cracking or settlement that calls for an engineer’s assessment

If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Surfaces we seal

  • Car park decks and ramps
  • Blockwork control joints
  • Podiums and floor movement joints
  • Brickwork movement joints
  • Cladding panel joints
  • Precast concrete panel joints

Hackington: questions and answers

Does your area include sites such as Maybrook Retail Park, near Hackington?

Yes. Our area takes in Hackington and its surroundings, with estates and business parks such as Maybrook Retail Park included. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Hackington too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you seal joints in cold or wet weather?

Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Indoor joints can normally carry on regardless.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Include photos or drawings if you have them.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Different surfaces, different methods

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
