About our expansion joint sealing in Friar's Gate

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on cladding panel joints, blockwork control joints and brickwork movement joints, and what we’re called in for most is brittle, chalky sealant on external joints and expansion joints split through the centre of the bead. Searching for sealant specialists in Friar's Gate? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Halls, schools and small commercial buildings near places like Friar's Gate have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Whether the work must be split into stages

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • A wide shot and a close-up of the area
  • The postcode of the building
  • When you need the work done
  • Approximate linear metres or a joint schedule

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email the details over.

Your questions answered

Is a hospital such as Crowborough War Memorial Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Friar's Gate too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

How long before the joints can be used?

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

Does the weather affect joint sealing?

A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Can a joint be sealed if the edges are broken?

Sound edges are essential. Where they’ve broken up, we’ll tell you they need repairing first.

Common problems we fix in Friar's Gate

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way.

These are often picked up first by site or facilities staff:

  • Damp inside where a wall movement joint has failed
  • Leaks through car park deck joints onto the level below
  • Layers of sealant in a movement joint
  • Expansion joints split through the centre of the bead

Hospital campuses such as Crowborough War Memorial Hospital, 1.8 miles to the south-east of Friar's Gate, grow in stages, leaving movement joints wherever new blocks meet old.

Before you book anyone

  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • Whether their applicators hold CSCS cards
  • Their public liability cover

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Friar's Gate need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid 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

  • Point out any areas we must not close
  • Confirm the product named in the specification

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Report split or peeling joint sealant early
  • Keep racking legs and heavy point loads off floor joints
  • Inspect movement joints alongside other routine building checks

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.

When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.
