Expansion joint sealing for businesses in Debden

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Debden can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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.

What we need from you

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Agree which areas must stay open

Related advice

Expansion joint sealing in Debden

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. If you are dealing with damp inside where a wall movement joint has failed and sealant pulling off the joint face, we can put it right, whatever the surface. Most enquiries from Debden start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

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

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Do you need expansion joint sealing in Debden?

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.

What tends to prompt an enquiry:

  • Debris jammed in movement joints
  • Water dripping through deck or ramp joints
  • Layers of sealant in a movement joint
  • Rain penetration at brick or block movement joints

For an estate such as Saffron Walden Community Hospital, which lies north of Debden, the joints in ramps, decks and long building elevations all need attention over time.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • How joint depth will be controlled
  • Their pre-qualification and accreditations

Choosing a commercial sealant contractor

When it isn’t the sealant

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

  • Leaks coming from the membrane rather than the joint seal
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Joints too narrow for the movement, which need redesigning by the engineer

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

  • Car park decks and ramps

Expansion joint sealing in Debden: the local picture

Debden is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Debden is about 36 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.

In a school such as Joyce Frankland Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Debden is about 3 miles south of Saffron Walden, in Essex. Businesses, contractors and managing agents in Debden use us for work on movement joints. Debden is one of 644 places in Essex on our list for movement joints. Sites around London have their own page, about 36 miles away.

Cost factors for movement joints

These are the things that shape the price:

  • The product specified
  • Distance, for remote addresses
  • The total length or number of joints
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

However big the job, the same details help:

  • Your programme or deadline
  • Clear photos of the problem areas
  • Whether the building will be occupied during the work
  • Specification clauses that apply

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or email us.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

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.

Questions we are asked in Debden

Does a site in Debden have to shut while its joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Can you take on a job at a hospital such as Saffron Walden Community Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you reseal car park expansion joints?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Can a joint be sealed if the edges are broken?

Spalled edges need repairing before a new seal will last, and we will point out where that’s the case. A bead on a broken edge soon lets go.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Looking after the joints

To get the most from the new sealant:

  • Keep product details with the building records for the next reseal
  • Treat a small split as a warning, not a cosmetic issue
  • Keep racking legs and heavy point loads off floor joints
  • Put movement joints on the planned maintenance inspection round

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.
