Expansion joint sealing across Addington

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. Jobs in and around smaller places like Addington are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

About our expansion joint sealing in Addington

A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you have spalled or broken joint edges in floors and decks and expansion joints filled with dirt and stones, we can help, on blockwork control joints, precast concrete panel joints and car park decks and ramps alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Addington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Addington are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What we’re called out for in Addington

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Most enquiries start with one or more of the following:

  • Joints packed with grit and debris
  • Previous reseals laid over old sealant
  • Damp inside where a wall movement joint has failed
  • Water dripping through deck or ramp joints

Across sites such as Invicta Business Park, 2.4 miles west of Addington, floor and movement joints can be sealed in phases so units keep working.

What your quote should include

  • Their plan for phasing and protecting the area
  • What site paperwork they can supply
  • Proof of insurance
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Older rural buildings around Addington move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Why us?

  • Colour agreed before work starts
  • A fixed quote before work starts
  • A range of standard colours, depending on the product
  • RAL and finish matching where the product range allows

Expansion joint sealing around Addington: how the place shapes the job

The 3 miles around Addington take in two named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Addington sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.

For buildings at a park such as Kings Hill Business Park (2.1 miles south of Addington), brick and panel movement joints are easy to forget until one leaks. In a school such as Offham Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Addington is about 7 miles north-west of Maidstone, in Kent. Any commercial site in Addington is covered, whether it’s a single job or part of a planned programme. Addington is one of 931 places we cover in Kent for movement joints. London is covered too, some 25 miles away.

Commercial sites across ME19 are covered. Streets here include London Road, The Links and Trottiscliffe Road, and sites on any of them can send details for a fixed quote. If your building is just outside Addington, we cover Ryarsh (1 mile north-east), Trottiscliffe (1 mile north-west), Vigo Village (2 miles north-west), Culverstone Green (3 miles north-west) and Harvel (3 miles north). Further afield, our area takes in Maidstone (7 miles south-east), Sittingbourne (15 miles east), Dartford (12 miles north-west), Sevenoaks (9 miles west), Royal Tunbridge Wells (13 miles south-west) and Gravesend (9 miles north).

FAQs: Addington

Is Addington too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Kings Hill Business Park, near Addington?

Yes. We cover Addington and the area around it, including industrial estates, business parks and retail parks such as Kings Hill Business Park. Photos and a short description are enough for a first look.

Is movement joint sealing guaranteed?

Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Brief car park operatives to protect joint lines during winter clearance
  • Keep stones and debris out of open joint lines
  • Report split or peeling joint sealant early
  • Avoid parking heavy plant or pallets on joint lines

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can speak to us on 01277 525 020 or use the quote form and send a picture.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.

Commercial clients in Addington

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Changing the joint layout or spacing of a structure
  • Waterproofing layers buried beneath the sealant
  • Crumbling edges that would give a new bead nothing sound to grip

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

  • Cladding panel joints
