About our expansion joint sealing in Bedfont

Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. Site teams most often ask us about damp inside where a wall movement joint has failed and joints where the bead has lost adhesion, across cladding panel joints, car park decks and ramps and precast concrete panel joints. For commercial sealant work in Bedfont, you deal with one contact from quote to sign-off, whether it’s one building or several.

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

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, 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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Bedfont: questions and answers

Can you work on a hospital site such as Ashford Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do you take on jobs in Bedfont where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do the joint edges need to be sound before sealing?

The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you’re not paying for a bead that won’t hold.

How much does the work cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Do you seal on top of existing sealant?

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 about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a job in Bedfont, access comes first: 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. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Proprietary pre-formed expansion joint systems
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.

What we seal

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

Why deal with it now?

Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s usually not far behind. We can price a patch and a full reseal side by side. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Cost factors for movement joints

Each job is priced on its own details. The main factors are:

  • Any access equipment needed
  • Distance, for remote addresses
  • Phasing around occupants
  • Site requirements such as inductions and permits

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • The product your specification calls for
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or use the quote form.
