Halls, schools and small commercial buildings near places like Hawthorn have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in Hawthorn
Waiting for a site-wide shutdown often means the joints keep getting worse. Phased in zones, the busiest routes can be treated first and the remainder follows on a plan that suits you. One visit to deal with every failing joint makes more sense than several trips to a place like Hawthorn, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Hawthorn: questions and answers
Is Hawthorn off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does the sea air around Hawthorn change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Do you repair broken joint edges?
We check the edges as part of the survey. Damaged edges are flagged up front so the filling isn’t wasted.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Building owners, agents and FMs in Hawthorn
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Surface by surface
Semi-rigid joint fillers
For trafficked warehouse joints, semi-rigid fillers are common. They are installed to the depth the manufacturer specifies and finished flush.
Construction joints
Day joints on busy routes are prone to edge damage. We look at how much they are moving before choosing the treatment.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Let us know what the floor is cleaned with
- Photograph any joint that starts to chip
- Plan for a top-up on newer floors
- Put loading bays at the top of the list
Ask drivers not to drag forks or pallets along the floor. Steel tines will mark a good joint over time.
Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out so nothing is left to fail.
Slabs, ramps and loading bays in Hawthorn
Hawthorn sits close to the coast, within about 2 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Large sites such as Queen Victoria Memorial Hospital, 1.4 miles west of Hawthorn, have car parks, service roads and long elevations with movement joints in brick and panels. Phasing is what makes joint work possible on busy sites such as Chislet Business Park (2.6 miles south of Hawthorn): one bay, aisle or car park row at a time. Schools such as Reculver Church of England Primary School have movement joints in their walls and floors that are easy to overlook.
Hawthorn is about 2 miles east of Herne Bay, in Kent. Businesses, contractors and managing agents in Hawthorn can call on us for floor joints. Hawthorn is one of 931 places we cover in Kent for floor joints. There’s a separate page for London, about 56 miles away.

How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Hawthorn, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We look at joint widths, edge condition and the traffic on each route.
- The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- Each phase reopens when the product is ready for wheels, then we start the next.
Before we start on site
- Send your site hours and access windows
- Have the specification and drawings to hand
- Let building users know which areas are affected

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Damaged or worn floor coatings and screeds
- A floor that rocks at the joints, which needs a structural fix
- Spalled arrises, which need an edge repair first
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
