Expansion joint sealing in Charing Cross, done properly
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic. We work on precast concrete panel joints, car park decks and ramps and blockwork control joints, and the usual reasons a site gets in touch are layers of sealant in a movement joint and chipped joint edges on forklift routes. A specialist sealant contractor works differently from a general builder: on jobs in Charing Cross, preparation and product choice get the time they need.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
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.

Leave it or put it right?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. We cut out the old seal and prepare the faces every time. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

When to call us in Charing Cross
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.
What tends to prompt an enquiry:
- Sealant peeling off one face of the joint
- Water getting into the wall through a failed joint
- Weathered movement joint sealant that no longer flexes
- Expansion joints split through the centre of the bead
A campus such as University of Notre Dame, less than half a mile to the north-west of Charing Cross, has long runs of movement joint in its buildings, decks and paving.

Cost factors for movement joints
The price varies from site to site. It mainly depends on:
- How much there is to seal
- Joint width, depth and condition
- How accessible the joints are
- Distance, for remote addresses
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Any dates the work must fit around
- The site address and postcode
- Access details, including height
- Drawings or a marked-up plan, if available
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
FAQs: Charing Cross
Does your area include sites such as Grand Vitesse Industrial Estate, near Charing Cross?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Is any job too small?

What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Which product is best for expansion joints?
Whatever suits the joint and the specification. We name the proposed product in the quote so there are no surprises.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- A joint that has to be widened or re-detailed before it can work
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Leaks coming from the membrane rather than the joint seal
If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Charing Cross can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, joint lengths and drawings come to us, or we visit.
- 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.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
