Monkhams: questions and answers

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it

Will you take on work at estates like Woodford Trading Estate, close to Monkhams?

Yes. Our area takes in Monkhams and its surroundings, with estates and business parks such as Woodford Trading Estate included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What exactly is a movement joint?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Are you insured?

Yes. We are fully insured, including public liability cover.

Expansion joint sealing for commercial buildings in Monkhams

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. The enquiries we see most involve previous reseals laid over old sealant and rain penetration at brick or block movement joints, on brickwork movement joints, podiums and floor movement joints and cladding panel joints. Whoever orders the work in Monkhams, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around Monkhams, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

Advice

Leave it or put it right?

Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s normally not far behind and repeated access costs add up. We can price a patch and a full reseal side by side. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Joints that move: notes for Monkhams

Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures. Less than 3 miles from Monkhams there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For a school such as Wells Primary School, playground and building joints can be done in the holidays. A healthcare site such as The Holly Private Hospital, 0.6 miles to the north-east of Monkhams, depends on car parks, ramps and service yards whose joints take traffic all day.

Monkhams is about 1 mile north of Woodford, in Greater London. Commercial clients in Monkhams use us for work on movement joints, as part of our coverage of Greater London. Our Greater London coverage takes in 764 places. London is covered too, some 10 miles away.

What we’re called out for in Monkhams

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.

It’s worth sending us details if you spot any of the following:

  • Joints where the bead has lost adhesion
  • New sealant over old, now failing
  • Spalled or broken joint edges in floors and decks
  • Water getting into the wall through a failed joint

Another example is Walthamstow Business Centre (2.1 miles south-west of Monkhams), where floors and yards would be done in stages around the occupiers.

What to look for in a quote

  • How joint depth will be controlled
  • Will RAMS and insurance details be available?
  • Whether their applicators hold CSCS cards
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Different surfaces, different methods

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Induction, permit and paperwork requirements

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Clear photos of the problem areas
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

To get a fixed quote, speak to us on 01277 525 020 or email drawings and photos. You can also send details through our quote form.
