Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What the job involves on each surface

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.

About our expansion joint sealing in Becontree Heath

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. If you’re dealing with movement joints with split or torn sealant and water dripping through deck or ramp joints, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Becontree Heath is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Areas such as a loading bay or car park deck in Becontree Heath normally have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Whoever the client is, the cover is the same: 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.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. In Becontree Heath, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Related advice

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Owners, agents and contractors

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.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Clear dirt from joint lines during routine cleaning
  • Keep product details with the building records for the next reseal
  • Look over external and deck joints after a hard winter

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Common questions from Becontree Heath clients

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.

Does your area include sites such as Business Centre, near Becontree Heath?

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

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do the joint edges need to be sound before sealing?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we will say so when we quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Cost factors for movement joints

Your fixed quote is built from the real scope. It allows for:

  • Whether the work must be split into stages
  • The product specified
  • Removal of failed or old sealant
  • Access and working height

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Any specification or named product
  • The asbestos register, for older buildings
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email the details over to discuss it first.

Expansion joint sealing in Becontree Heath: the local picture

The 3 miles around Becontree Heath take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager.
