What happens if it’s left?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. Around Deerton Street, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why us?

  • A range of standard colours, depending on the product
  • Workmanship guaranteed for 12 months
  • Colours chosen to suit frames, cladding or finishes where possible
  • One contact handling all your sites

Building owners, agents and FMs in Deerton 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, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Concrete or masonry repairs along the arrises
  • A joint that has to be widened or re-detailed before it can work
  • Movement on a scale no sealant is meant to absorb

Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.

Surfaces we seal

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

Your questions answered

Will our site in Deerton Street have to close for joint sealing?

Usually not: we work in sections and hand each one back once it has cured. Tell us which hours and entrances we can use and we will plan from there.

Does a coastal location like Deerton Street affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can the building stay open while you work?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

What guarantee do you give on joint sealing?

It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

How the job changes by surface

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For a building around Deerton Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Have the specification and drawings to hand
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

Advice

Traffic, movement and joints around Deerton Street

Deerton Street lies within about 2 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. The South East is one of the drier parts of the UK. 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 a school such as Teynham Parochial Church of England Primary School, playground and building joints can be done in the holidays. Around Deerton Street, each joint gets a filler or sealant matched to what crosses it and how much it moves.
