Expansion joint sealing for commercial buildings in Hobbs Cross

Long runs of brick or block have movement joints built in. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. Site teams most often ask us about leaks through car park deck joints onto the level below and sealant pulling off the joint face, on blockwork control joints, brickwork movement joints and cladding panel joints. Facilities teams, main contractors and managing agents in Hobbs Cross tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site near Hobbs Cross, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Leave it or put it right?

A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. Converted and older buildings near places like Hobbs Cross tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

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’ll have a fixed figure to work with.

Doing it in-house

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Your questions answered

Do you cover business parks and estates near Hobbs Cross, such as Hobbs Cross Business Centre?

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

Is a smaller place like Hobbs Cross outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is movement joint sealing guaranteed?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first, because the fix differs.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Hobbs Cross, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

How the job changes by surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

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.

Do you need expansion joint sealing in Hobbs Cross?

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Common reasons buildings call us in:

  • Hardened, cracked sealant on exposed facades
  • New sealant over old, now failing
  • Joints where the bead has lost adhesion
  • Movement joints with split or torn sealant

Across sites such as Brickfield House Business Centre, 2.6 miles north of Hobbs Cross, floor and movement joints can be sealed in phases so units keep working.

What your quote should include

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • Who will actually carry out the work
  • Their plan for phasing and protecting the area
