Expansion joint sealing across Dean Street

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

How we handle expansion joint sealing in Dean Street

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 leaks through car park deck joints onto the level below and brittle, chalky sealant on external joints, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dean Street is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Dean Street, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

FAQs: Dean Street

Is Dean Street off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Tovil Green Business Park, close to Dean Street?

Yes. We cover Dean Street and the area around it, including industrial estates, business parks and retail parks such as Tovil Green Business Park. Send details of the unit and the work through our quote form for a quick quote.

Will you just go over the old sealant?

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

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Do you guarantee expansion joint work?

A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Quoting for work in Dean Street

To price the job, we consider:

  • Working within restricted access windows
  • Location, for remote and island sites
  • The size and state of each joint
  • Access and working height

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Access details, including height
  • Approximate linear metres or a joint schedule
  • Your programme or deadline

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Rural sites near Dean Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Point out any areas we must not close
  • Explain the parking and delivery arrangements

Slabs, ramps and loading bays in Dean Street

At least three named trading, business or retail sites lie within about 3 miles of Dean Street. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Rainfall across the South East, Dean Street included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

At places like Powerhub Business Centre, which lies north-east of Dean Street, joints are sealed a section at a time so operations carry on. Sites like Maidstone Hospital, 1.8 miles to the north of Dean Street, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Centres like The Mall Maidstone, 2 miles north-east of Dean Street, have mall floors and service decks whose joints carry steady traffic.

Dean Street is about 2 miles south-west of Maidstone, in Kent. Businesses, contractors and managing agents in Dean Street can call on us for movement joints. Dean Street is one of 931 places in Kent on our list. Sites around London have their own page, roughly 31 miles from Dean Street.

Work on movement joints is covered throughout ME15. Streets here include Forge Lane and Dean Street, and sites on any of them can send details for a fixed quote. Nearby places we also cover include East Farleigh (1 mile west), Coxheath (1 mile south), Fant (1 mile north), Kettle Corner (1 mile west) and Farleigh Green (1 mile west). Bigger towns within reach include Sittingbourne (12 miles north-east), Sevenoaks (14 miles west), Royal Tunbridge Wells (13 miles south-west), Gravesend (13 miles north), Tonbridge (10 miles west) and Northfleet (14 miles north-west).

Commercial clients in Dean Street

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.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Why deal with it now?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we will plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Dean Street, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
