How we handle expansion joint sealing in Temple End

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing and phasing can keep areas working. If you have hardened, cracked sealant on exposed facades and expansion joints filled with dirt and stones, we can help, whatever the surface. Searching for sealant specialists in Temple End? We have been sealing commercial buildings since 2005.

Halls, schools and small commercial buildings near places like Temple End 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.

What happens if it’s left?

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. For buildings around smaller places like Temple End, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

FAQs: Temple End

Can you take on a job at a hospital such as Pinehill Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Temple End too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

What timescale should we allow for resealing expansion joints?

It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. We confirm the timescale with the quote.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

What about RAMS and site documents?

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.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

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, with each stage agreed with your site contact.

How the job changes by surface

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.

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

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. For work around Temple End, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached
  • Warn occupants and staff about the work

When to bring in 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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Traffic, movement and joints around Temple End

Temple End sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At about 31 miles from central London, Temple End is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds.

For a school such as Hitchin Boys' School, playground and building joints can be done in the holidays. Sites like Pinehill Hospital (to the north-east of Temple End) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
