Chalk: questions and answers
Is Lion Business Park, near Chalk, within your area?
Yes. Our area takes in Chalk and its surroundings, with estates and business parks such as Lion Business Park included. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Gravesham Community Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work on car park ramps and decks?
Yes. These joints take wheels, salt and water, so product choice matters.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Do the joint edges need to be sound before sealing?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How long will the joint resealing take?
It usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote along with the phasing plan.
Traffic, movement and joints around Chalk
Chalk is within about 2 miles of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. At least three named trading, business or retail sites lie within about 3 miles of Chalk. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Parks like Lion Business Park, 0.9 miles north-west of Chalk, combine paved areas, car parks and building elevations, each with joints that move. Another example is Canal Industrial Park, which lies north-west of Chalk, where floors and yards would be done in stages around the occupiers.
Chalk is about 1 mile east of Gravesend, in Kent. Across the DA12 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Chalk can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Share your working hours and any access restrictions

Advice
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, 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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Leave it or put it right?
Resealing is typically the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. Older rural buildings around Chalk move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What we’re called out for in Chalk
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
If one of these sounds familiar, it’s time for a closer look:
- Damp inside where a wall movement joint has failed
- Expansion joints split through the centre of the bead
- Weathered movement joint sealant that no longer flexes
- Debris jammed in movement joints
Schools such as Thamesview School have movement joints in their walls and floors that are easy to overlook.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it
- How long is the guarantee, and what does it include?
- The named product and why it was chosen
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Different surfaces, different methods
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.
What affects the price in Chalk
A fixed quote reflects the actual work. It takes account of:
- How accessible the joints are
- Removal of failed or old sealant
- Location, for remote and island sites
- Joint width, depth and condition
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- The postcode of the building
- Any specification or named product
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
