Expansion joint sealing for North Ockendon sites

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

How we handle expansion joint sealing in North Ockendon

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. Site teams most often ask us about weathered movement joint sealant that no longer flexes and debris jammed in movement joints, on precast concrete panel joints, podiums and floor movement joints and car park decks and ramps. A single leaking joint is often how a building in North Ockendon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In North Ockendon, as everywhere in London, access, loading and the ULEZ all come into the plan.

Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

How the job changes by surface

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • How accessible the joints are
  • How much existing material needs removing

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Photos of the joints, close up and from further back
  • Access details, including height
  • The product your specification calls for
  • The postcode of the building

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or email a schedule or drawings.

Why act early in North Ockendon

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. In North Ockendon, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Why clients in North Ockendon choose us

  • 12-month guarantee on workmanship
  • Colour options checked against the specified product

  • Colours chosen to suit frames, cladding or finishes where possible

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in North Ockendon can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.

Related advice

Your questions answered

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly.

Do you cover business parks and estates near North Ockendon, such as Horndon Industrial Estate?

Yes, sites like Horndon Industrial Estate are within our area, along with the rest of North Ockendon. Send details of the unit and the work through our quote form for a quick quote.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load.

Are you fully insured?

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

How long does movement joint sealing take?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote along with the phasing plan.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Which product is best for expansion joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote, so you know what’s going in.

Owners, agents and contractors

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Slabs, ramps and loading bays in North Ockendon

North Ockendon has two named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment. Basement car parks and service yards in London tend to be in use all working day, so joints are sealed in sections with each area handed back once cured.

For a centre such as Ealing Broadway Centre (2.2 miles south of North Ockendon), the service yard and car park joints usually need attention first. For a school such as The James Oglethorpe Primary School, playground and building joints can be done in the holidays. Another example is Childerditch Industrial Park, 2.9 miles north-east of North Ockendon, where floors and yards would be done in stages around the occupiers.
