- How much existing material needs removing
- Quantities, in metres or numbers
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Questions about Coldblow
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Can you work on a hospital site such as Erith and District Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes a day or more, depending on the metres of joint and how many zones the floor is split into. For bigger or phased jobs, we will set out a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in Coldblow, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- We walk the floor and mark up joint widths, edge damage and traffic routes.
- The treatment and the zones are set out in a fixed quote.
- Old fill and packed debris come out until both faces are sound.
- We extract the dust and prime the faces if the product needs it.
- Filler or sealant is placed to depth and finished flush.
- Zones reopen once cured and the work moves on.
Preparing the site
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance

When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Wide or random cracking that suggests a structural issue
- A floor that is out of level for the racking or trucks
- Spalled arrises, which need an edge repair first
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly.
Surfaces we seal
- Loading bays
- Construction joints
- Retail and showroom floors
- Saw-cut induced joints
- Joints along racking aisles
- Forklift and pallet-truck routes
Slabs, ramps and loading bays in Coldblow
Coldblow has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.
In a school such as Maypole Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Sites like Erith and District Hospital, 2.7 miles north of Coldblow, carry ambulances, deliveries and visitors’ cars over their road and deck joints. On a site such as Old Bexley Business Park, 0.6 miles north-west of Coldblow, the movement joints are in car park slabs, paving and building elevations.

Leave it or put it right?
Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, adding costs nobody plans for. A properly filled joint smooths the route. Getting scaffold, permits or access booked in Coldblow takes effort, so it makes sense to deal with every failing joint while access is in place.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
