Expansion joint sealing for Stockbury sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Common problems we fix in Stockbury
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.
These are often picked up first by site or facilities staff:
- Weathered movement joint sealant that no longer flexes
- Arrises breaking up along floor joints
- Expansion joints split through the centre of the bead
- Rain penetration at brick or block movement joints
On industrial estates such as Newington Industrial Estate, 2 miles north of Stockbury, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Questions to ask before you book
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
- How joint depth will be controlled

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions we’re asked in Stockbury
Is Newington Industrial Estate, near Stockbury, within your area?
Yes. Our area takes in Stockbury and its surroundings, with estates and business parks such as Newington Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Stockbury 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. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
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.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Quoting for work in Stockbury
We price every job individually. The things that drive the figure:
- Working within restricted access windows
- The site’s rules and procedures
- Access and working height
- The product specified
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- When you need the work done
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email a schedule or drawings.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Proprietary pre-formed expansion joint systems
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Movement on a scale no sealant is meant to absorb
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Car park decks and ramps
- Podiums and floor movement joints
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints
- Precast concrete panel joints
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Warehouse floors and decks around Stockbury
Rainfall across the South East, Stockbury included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. The 3 miles around Stockbury take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Sites like KIMS hospital, 4.5 miles to the south-west of Stockbury, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Phasing is what makes joint work possible on busy sites such as Parkwood Shopping Centre (2.5 miles north-west of Stockbury): one bay, aisle or car park row at a time.

How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Stockbury, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
