When to call us in The Heath
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
Look out for the following:
- Debris jammed in movement joints
- Arrises breaking up along floor joints
- Rain penetration at brick or block movement joints
- Car park joints leaking onto vehicles below
Hospitals like Keech Hospice Care, 5.1 miles to the north-west of The Heath, have multi-storey or surface car parks whose joints carry vehicles round the clock.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
Expansion joint sealing in The Heath, done properly
If you need expansion joint sealing in The Heath, start with photographs and joint lengths. We will come and look where photos don’t show enough. You can also phone 01277 525 020 or email us to talk the joints through. If you are dealing with sealant pulling off the joint face and layers of sealant in a movement joint, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in The Heath, preparation and product choice get the time they need.
Jobs around smaller places like The Heath are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: The Heath
Is a smaller place like The Heath outside your area?
Not at all. The Heath is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Barratt Industrial Park, near The Heath, within your area?
Yes. Our area takes in The Heath and its surroundings, with estates and business parks such as Barratt Industrial Park included. A few photos and the unit address let us price the work.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.
Surfaces we seal
- Blockwork control joints
- Cladding panel joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Car park decks and ramps
- Brickwork movement joints
What the job involves on each surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen in a colour confirmed for that product.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Doing it in-house
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.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Clear dirt from joint lines during routine cleaning
- Keep scrapers and ploughs from dragging across joint sealant
- Reopen bays and walkways only after the stated cure time
- Check joints after long freezing spells
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Jobs in and around smaller places like The Heath are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work

Slabs, ramps and loading bays in The Heath
The Heath has two named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.
Another example is Butterfield Business Park (2.8 miles north-west of The Heath), where floors and yards would be done in stages around the occupiers. For an occupier at a site such as Barratt Industrial Park, 2.6 miles to the south-west of The Heath, the joints at loading doors and dock levellers normally see the hardest wear.
