When to bring in a specialist
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Reopen bays and walkways only after the stated cure time
- Avoid parking heavy plant or pallets on joint lines
- Check joints after long freezing spells
- Brief car park operatives to protect joint lines during winter clearance
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can speak to us on 01277 525 020 or email the details over and send a picture.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
Surface by surface
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Floors, slabs and movement joints in Brentham Garden Suburb
The 3 miles around Brentham Garden Suburb 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. Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- 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.
Preparing the site
- Warn occupants and staff about the work
- Share your working hours and any access restrictions
- Move anything stored against the joints

Common questions from Brentham Garden Suburb clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Manhattan Business Park, by Brentham Garden Suburb?
Yes. Our area takes in Brentham Garden Suburb and its surroundings, with estates and business parks such as Manhattan Business Park included. Photos and a short description are enough for a first look.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Which product is best for expansion joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class so there are no surprises.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
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.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Brentham Garden Suburb can sit alongside others in a wider programme across Greater London.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Any access equipment needed
- Working within restricted access windows
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
However big the job, the same details help:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Specification clauses that apply
- Approximate linear metres or a joint schedule
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
