Expansion joint sealing in Bromley Common: the local picture

The 3 miles around Bromley Common 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. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

For buildings at a park such as Chartwell Business Centre, 1 mile to the north of Bromley Common, brick and panel movement joints are easy to forget until one leaks. University campuses such as University of Greenwich - Avery Hill, 4.7 miles to the north-east of Bromley Common, have car parks, paved walkways and building elevations with movement joints.

Bromley Common is about 2 miles south-east of Bromley, in Greater London. We send applicators to Bromley Common for movement joints, handled exactly as we handle every other area. Bromley Common is one of 764 places we cover in Greater London. Sites around London have their own page, roughly 10 miles from Bromley Common.

Anyone looking for expansion joint sealing in BR2 and BR1 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Pope Road, Crown Lane and Church Lane are within our area. We also cover Southborough (1 mile north-east), Hayes (1 mile south-west), Locksbottom (1 mile south-east), Shortlands (2 miles north-west) and Keston (2 miles south). Nearby towns on our patch include London (10 miles north-west), City of Westminster (12 miles north-west), Marylebone (12 miles north-west), Kensington (13 miles north-west), St Pancras (12 miles north-west) and Shoreditch (11 miles north-west).

Expansion joint sealing in Bromley Common, done properly

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and the failures we’re asked to look at most are damp inside where a wall movement joint has failed and expansion joints split through the centre of the bead. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bromley Common it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we are called out for in Bromley Common

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

It’s worth sending us details if you spot any of the following:

  • Joints where the bead has lost adhesion
  • Weathered movement joint sealant that no longer flexes
  • Movement joints with split or torn sealant
  • Water dripping through deck or ramp joints

At a retail site such as The Mall (1.5 miles north-west of Bromley Common), trolleys, cages and cars run over floor and slab joints all day.

What to look for in a quote

  • Their approach to joint depth and backing
  • Whether old or failed sealant will be cut out, not overlaid
  • Is the sealant right for the movement and the substrate?
  • Proof of insurance

Questions to ask before you appoint anyone

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Planning a London job such as one in Bromley Common starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use

Cost factors for movement joints

Each job is priced on its own details. The things that drive the figure:

  • Removal of failed or old sealant
  • Which sealant the job calls for
  • The size and state of each joint
  • Travel to remote or island sites

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

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

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • What the building is and how it’s used

To get a fixed quote, speak to us on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.

Questions about Bromley Common

Do you cover business parks and estates near Bromley Common, such as Chartwell Business Centre?

Yes. We cover Bromley Common and the area around it, including industrial estates, business parks and retail parks such as Chartwell Business Centre. Send details of the unit and the work through our quote form for a quick quote.

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can staff carry on working while you are here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

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.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

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.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Getting scaffold, permits or access booked in Bromley Common takes effort, so it makes sense to deal with every failing joint while access is in place.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep scrapers and ploughs from dragging across joint sealant
  • Look over external and deck joints after a hard winter
  • Reopen bays and walkways only after the stated cure time

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. Regular sweeping keeps joint lines clear.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Catching it early keeps the water outside.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Concrete or masonry repairs along the arrises
  • Damaged metal nosings or cover plates over a joint
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.
