Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Put movement joints on the planned maintenance inspection round
- Raise snow-clearing blades over deck joints where possible
- Clear dirt from joint lines during routine cleaning
- Check joints after long freezing spells
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. A sound seal keeps the joint working.
How we handle expansion joint sealing in High Cross
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, blockwork control joints and cladding panel joints, and the failures we are asked to look at most are sealant peeling off one face of the joint and previous reseals laid over old sealant. One point of contact handles commercial sealant work in High Cross from the first photographs to the final walk-round, whether it’s one building or several.
For a site near High Cross, measurements and photos up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.
Whoever the client is, the cover is the same: 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.

Central London is about 35 miles from High Cross. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.

Questions about High Cross
Will you take on work at estates like Millbrook Industrial Estate, close to High Cross?
Yes, sites like Millbrook Industrial Estate are within our area, along with the rest of High Cross. A few photos and the unit address let us price the work.
Would you work within a site like Crowborough War Memorial Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What happens if it rains on the day?
Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
Do you use silicone or polyurethane in movement joints?
Movement capability matters most. Where two different materials meet, a hybrid sealant can be the better choice.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you need expansion joint sealing in High Cross?
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears.
Any of the following is a good reason to get the joints checked over:
- Chipped joint edges on forklift routes
- Joints where the bead has lost adhesion
- Joints packed with grit and debris
- Movement joints with split or torn sealant
Schools such as Rotherfield Primary School have movement joints in their walls and floors that are easy to overlook.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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 typically costs more in the end than doing them right.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like High Cross are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- 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.
