Expansion joint sealing in Lower Farringdon, done properly

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on brickwork movement joints, car park decks and ramps and podiums and floor movement joints, and what we are called in for most is joints where the bead has lost adhesion and debris jammed in movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lower Farringdon it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Halls, schools and small commercial buildings near places like Lower Farringdon have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Leave it or put it right?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Converted and older buildings near places like Lower Farringdon tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What you get with us

  • Fixed quotes based on photographs, drawings or a visit
  • Joints cleaned back to sound surfaces
  • CSCS-carded applicators
  • Over 20 years of commercial sealing

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Proprietary pre-formed expansion joint systems
  • Concrete or masonry repairs along the arrises

If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

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

Cost factors for movement joints

Your fixed quote is built from the real scope. It takes account of:

  • Access and working height
  • The site’s rules and procedures
  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants

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 fixed quote when you’re ready.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • What the building is and how it’s used
  • When you need the work done
  • The postcode of the building
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Where floor joints take the most wear near Lower Farringdon

Lower Farringdon sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Lower Farringdon. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Large sites such as Alton Community Hospital (to the north of Lower Farringdon) have car parks, service roads and long elevations with movement joints in brick and panels. Another example is Farringdon Industrial Centre, which lies south of Lower Farringdon, where floors and yards would be done in stages around the occupiers. Business parks such as Farringdon Business Park, less than half a mile west of Lower Farringdon, have car parks, paved areas and long brick and panel elevations, all with movement joints.

Lower Farringdon is about 3 miles south of Alton, in Hampshire. Commercial clients in Lower Farringdon use us for work on movement joints. We work across 723 places in Hampshire. For work in that direction, see our Portsmouth page.

Questions about Lower Farringdon

Can you work at a site such as Farringdon Business Park, by Lower Farringdon?

Yes. Estates, retail parks and business parks around Lower Farringdon, Farringdon Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Is Lower Farringdon off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Why has the sealant in our expansion joints split?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first, because the fix differs.

Can a joint be sealed if the edges are broken?

Sound edges are essential. If they’re damaged, we’ll say so before any sealing so you are not paying for a bead that won’t hold.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. For work around Lower Farringdon, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Point out parking and an unloading spot

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Keeping the joints sound

To get the most from the new sealant:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Check joints after long freezing spells
  • Note which joints were done, when, and with what
  • Keep traffic off new joints until the cure time is up

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.
