Expansion joint sealing for businesses in Camden Town

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

What sets the cost

These are the things that shape the price:

  • Working within restricted access windows
  • The total length or number of joints
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • When you need the work done
  • A wide shot and a close-up of the area
  • The postcode of the building
  • Anything awkward about access or site hours

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Expansion joint sealing for commercial buildings in Camden Town

For movement joints in Camden Town, photographs and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed, then send a fixed quote that names the sealant. You can also give us a call on 01277 525 020 or email a schedule or drawings to talk the joints through. Most enquiries involve torn sealant in brick or block movement joints and arrises breaking up along floor joints, on precast concrete panel joints, brickwork movement joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, in Camden Town it comes down to the same thing: the right product in a properly prepared joint.

Around Camden Town, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall.

Every job we finish is backed by a 12-month workmanship guarantee, in Camden Town as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Leave barriers in place until fresh joint sealant has cured
  • Avoid parking heavy plant or pallets on joint lines
  • Inspect movement joints alongside other routine building checks
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.

Joints that move: notes for Camden Town

Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time. Less than 3 miles from Camden Town there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

A healthcare site such as St. Pancras Hospital (to the south-east of Camden Town) depends on car parks, ramps and service yards whose joints take traffic all day. A campus such as University of the Arts London (0.7 miles east of Camden Town) has long runs of movement joint in its buildings, decks and paving. Office parks like Regis Road Business Park (to the north of Camden Town) have decks, ramps and clad elevations whose joints take movement every day.

Camden Town is about 2 miles north of City of Westminster, in Greater London. We cover Camden Town, with the same fixed quotes and 12-month guarantee as everywhere else. Camden Town is one of 764 places we cover in Greater London for movement joints.

Business premises anywhere in NW1, N1C, NW5 and NW3 are within our area for movement joints. Buildings on Camden High Street, Greenland Road and Camden Road are within our area for movement joints. Being close to the A400 and B512, Camden Town is easy to get to with materials and equipment. Sites close to Camden Town are covered too, including Agar Town (1 mile east), Kentish Town (1 mile north-west), Chalk Farm (1 mile north-west), Somers Town (1 mile south-east) and Primrose Hill (1 mile west). Nearby towns on our patch include London (3 miles south-east), Kensington (4 miles south-west), Shoreditch (3 miles east), Walthamstow (6 miles north-east), Whitechapel (3 miles south-east) and Ruislip (12 miles west).

What’s near Camden Town

You’ll also find Lewis Cubitt Park (0.7 miles east) and Vaughan Williams Memorial Library (under half a mile west). Camden Town has its own railway station: Camden Road station. Other landmarks nearby include St Pancras Hospital (0.5 miles south-east) and Montfichet's Tower (2.5 miles south-east).

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Your questions answered

Does your area include sites such as Regis Road Business Park, near Camden Town?

Yes. We cover Camden Town and the area around it, including industrial estates, business parks and retail parks such as Regis Road Business Park. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Can you work on a hospital site such as St. Pancras Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Why has the sealant in our expansion joints split?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Proprietary pre-formed expansion joint systems
  • A joint that has to be widened or re-detailed before it can work
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

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

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Close-up photographs help us judge the joints.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Camden Town can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Make sure the joints can be reached
  • Let building users know which areas are affected
