About our expansion joint sealing in West Kingsdown
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you have joints packed with grit and debris and rain penetration at brick or block movement joints, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Kingsdown it comes down to the same thing: the right product in a properly prepared joint.
Around places the size of West Kingsdown, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Different surfaces, different methods
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen, and we will confirm the colours available for the specified product.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Inspect movement joints alongside other routine building checks
- Plan racking layouts so feet don’t land on a joint
- Leave barriers in place until fresh joint sealant has cured
- Treat a small split as a warning, not a cosmetic issue
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Sealing early protects the edges.

What else we do in West Kingsdown
When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Concrete or masonry repairs along the arrises
- A joint that has to be widened or re-detailed before it can work
- Leaks coming from the membrane rather than the joint seal
If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Common questions from West Kingsdown clients
Can you take on a job at a hospital such as Sevenoaks Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is West Kingsdown too small for you to travel to?
Not at all: smaller places are covered as well as towns. 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.
What causes movement joint sealant to fail?
Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. Working out the cause comes first.
Does the weather affect joint sealing?
Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Do you reseal car park expansion joints?
Yes, we do. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Signs you need expansion joint sealing in West Kingsdown
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Any of the following is a good reason to get the joints checked over:
- Leaks through car park deck joints onto the level below
- Spalled or broken joint edges in floors and decks
- Sealant pulling off the joint face
- New sealant over old, now failing
Across sites such as Blue Chalet Industrial Park, 0.5 miles to the north-west of West Kingsdown, floor and movement joints can be sealed in phases so units keep working.

- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.

- We check every joint before sign-off, and the work carries our 12-month guarantee.
