Aftercare for building managers
For the best life from the joints:
- Keep racking legs and heavy point loads off floor joints
- Raise snow-clearing blades over deck joints where possible
- Inspect exposed joints once the cold weather has passed
- Record the sealant used and the date in the O&M file
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
Expansion joint sealing for commercial buildings in Mountnessing
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you’re dealing with weathered movement joint sealant that no longer flexes and spalled or broken joint edges in floors and decks, we can help. Facilities teams, main contractors and managing agents in Mountnessing tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Halls, schools and small commercial buildings near places like Mountnessing have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Our process
Before we leave any area, 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. For a building around Mountnessing, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work
- Agree which areas must stay open
Ask for a quote

How the job changes by surface
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Movement on a scale no sealant is meant to absorb
- Damaged metal nosings or cover plates over a joint
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly.

Common problems we fix in Mountnessing
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
If one of these sounds familiar, it’s time for a closer look:
- Joints packed with grit and debris
- Water dripping through deck or ramp joints
- Water getting into the wall through a failed joint
- Movement joints with split or torn sealant
Schools such as Mountnessing Church of England Primary School have movement joints in their walls and floors that are easy to overlook.
