Expansion joint sealing in Crockenhill
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing. We work on blockwork control joints, podiums and floor movement joints and precast concrete panel joints, and the failures we are asked to look at most are expansion joints filled with dirt and stones and rain penetration at brick or block movement joints. Searching for sealant specialists in Crockenhill? We have been sealing commercial buildings since 2005.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Crockenhill, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
- Move anything stored against the joints

Why act early in Crockenhill
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too. We can price a patch and a full reseal side by side. For buildings around smaller places like Crockenhill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Pricing movement joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What you get with us
- Public liability insurance in place
- Over 20 years of commercial sealing
- A range of standard colours, depending on the product
- 12 months’ guarantee on every job

Common questions from Crockenhill clients
Do you take on work at healthcare sites like Chelsfield Park Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work at a site such as Mark Way Industrial Estate, by Crockenhill?
Yes. Our area takes in Crockenhill and its surroundings, with estates and business parks such as Mark Way Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Why do our movement joints keep failing?
The way it has failed normally tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email us. Include photographs or drawings if you have them.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do the joint edges need to be sound before sealing?
Sound edges are essential. If they’re damaged, we’ll say so before any sealing.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

Common problems we fix in Crockenhill
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.
Site and facilities staff are often the first to spot these:
- Leaks through car park deck joints onto the level below
- Sealant pulling off the joint face
- Brittle, chalky sealant on external joints
- Previous reseals laid over old sealant
Schools such as Crockenhill Primary School have movement joints in their walls and floors that are easy to overlook.

Looking after the joints
Once the work is signed off, these steps help:
- Inspect movement joints alongside other routine building checks
- Report split or peeling joint sealant early
- Plan racking layouts so feet don’t land on a joint
- Reopen bays and walkways only after the stated cure time
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
