Expansion joint sealing in Long Crendon
We cover the full range of movement joints: 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 and we name it in the quote. If you have weathered movement joint sealant that no longer flexes and movement joints with split or torn sealant, we can help, whatever the surface. Whoever orders the work in Long Crendon, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Small units near places like Long Crendon are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Should maintenance staff do it?
There’s also the paperwork. 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.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Common questions from Long Crendon clients
Can you work at a site such as Crendon Industrial Estate, by Long Crendon?
Yes. Estates, retail parks and business parks around Long Crendon, Crendon Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is Long Crendon 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. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What if there’s asbestos in the old mastic?
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.
What exactly is a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. On site, people tend to use them interchangeably.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Which product is best for expansion joints?
Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
When to call us in Long Crendon
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Site and facilities staff are often the first to spot these:
- Movement joints with split or torn sealant
- Previous reseals laid over old sealant
- Expansion joints filled with dirt and stones
- Chipped joint edges on forklift routes
Schools like Long Crendon School often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Who will actually carry out the work
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Inspect movement joints alongside other routine building checks
- Keep stones and debris out of open joint lines
- Note which joints were done, when, and with what
- Plan racking layouts so feet don’t land on a joint
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near Long Crendon can be grouped on one trip. Tell us your site hours and we will plan around them.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- 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

Why deal with it now?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too. Where it helps, we quote both options. In a smaller place such as Long Crendon, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

- Our applicators hold CSCS cards
- Colours chosen to suit frames, cladding or finishes where possible

Expansion joint sealing around Long Crendon: what changes locally
Long Crendon is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Long Crendon has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Across sites such as Christmas Hill Business Park, which lies south of Long Crendon, floor and movement joints can be sealed in phases so units keep working. Warehouse floors on estates like Crendon Industrial Estate (to the south-east of Long Crendon) carry pallet trucks and forklifts over every saw-cut joint.
