Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Check joints after long freezing spells
- Avoid parking heavy plant or pallets on joint lines
- Brief car park operatives to protect joint lines during winter clearance
- Include every elevation and deck joint in periodic inspections
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Barriers left in place until then protect the finish.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

What else we do in Bowcombe
Why it’s worth doing now in Bowcombe
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. Halls, stores and units around places like Bowcombe may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
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.

Common problems we fix in Bowcombe
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
It’s worth sending us details if you spot any of the following:
- New sealant over old, now failing
- Sealant pulling off the joint face
- Expansion joints filled with dirt and stones
- Torn sealant in brick or block movement joints
A healthcare site such as Laidlaw Day Hospital (to the north-east of Bowcombe) depends on car parks, ramps and service yards whose joints take traffic all day.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Their public liability cover
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Changing the joint layout or spacing of a structure
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Broken or spalled joint edges, which need repairing before any sealant goes in
If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal
- Cladding panel joints
- Precast concrete panel joints

Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
What causes movement joint sealant to fail?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
