Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Act on the first tear or lifting edge rather than waiting
- Keep product details with the building records for the next reseal
- Keep racking legs and heavy point loads off floor joints
- Leave barriers in place until fresh joint sealant has cured
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
Questions we’re asked in Newgate Street
Is Newgate Street too far out for you?
No. Places such as Newgate Street are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like Chase Farm Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Can a joint be sealed if the edges are broken?
Broken arrises have to be put right before resealing, and we will point out where that’s the case. A bead on a broken edge soon lets go.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Why deal with it now?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Newgate Street, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Newgate Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- Agree which areas must stay open

Before we quote, we look at:
- Distance, for remote addresses
- Site requirements such as inductions and permits
- Working within restricted access windows
- Joint width, depth and condition
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

To price the job accurately, we need a clear picture of the site. Useful things to include:
- Drawings or a marked-up plan, if available
- Your programme or deadline
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email drawings and photos.
Slabs, ramps and loading bays in Newgate Street
Newgate Street lies roughly 16 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Newgate Street is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
For estates staff at a university like University of Hertfordshire (3.5 miles north-west of Newgate Street), building and paving joints are part of the planned maintenance list. On industrial estates such as Sopers Road Industrial Estate, which lies south of Newgate Street, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Sites like Chase Farm Hospital (4.3 miles south of Newgate Street) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Changing the joint layout or spacing of a structure
- Damaged metal nosings or cover plates over a joint
- Concrete or masonry repairs along the arrises

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
