Common problems we fix in Codicote
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again.
Site and facilities staff are often the first to spot these:
- Car park joints leaking onto vehicles below
- Joints packed with grit and debris
- Rain penetration at brick or block movement joints
- Brittle, chalky sealant on external joints
Large sites such as Queen Elizabeth II Hospital, 5 miles to the south-east of Codicote, have car parks, service roads and long elevations with movement joints in brick and panels.

Expansion joint sealing in Codicote
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We will tell you if the edges need repairing before sealing. We work on car park decks and ramps, brickwork movement joints and cladding panel joints, and the usual reasons a site gets in touch are joints packed with grit and debris and sealant pulling off the joint face. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Codicote is the same: the right product in a properly prepared joint.
In a smaller place such as Codicote, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Warehouse floors and decks around Codicote
At about 25 miles from central London, Codicote is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
Schools like Codicote Church of England Primary School often have long brick elevations with movement joints that age quietly.

Cost factors for movement joints
Each job is priced on its own details. The things that drive the figure:
- Whether old sealant has to be cut out first
- Which sealant the job calls for
- Distance, for remote addresses
- The size and state of each joint
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Photos of the joints, close up and from further back
- Access details, including height
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email us.
Our process
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. What matters most for a job in Codicote is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- 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 tell you if the design looks wrong for the movement.
- 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.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed

Advice
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Changing the joint layout or spacing of a structure
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think.

FAQs: Codicote
Can you take on a job at a hospital such as Queen Elizabeth II Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Must our site in Codicote stop work while the joints are done?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you work in Codicote?
Yes. We cover Codicote, and the simplest way to start is to ring 01277 525 020 or email us.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Commercial clients in Codicote
We work for building owners and managing agents on everything from one building to a spread of sites around Codicote. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Leave it or put it right?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. For buildings in places like Codicote, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
