Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Green Street Green, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Warn occupants and staff about the work

About our expansion joint sealing in Green Street Green
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints, and what we’re called in for most is car park joints leaking onto vehicles below and expansion joints filled with dirt and stones. A single leaking joint is often how a building in Green Street Green first comes to us: we look at the rest while we’re there and tell you what we find.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Green Street Green
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, so we tell you if the edges need repairing first.
What tends to prompt an enquiry:
- Previous reseals laid over old sealant
- Car park joints leaking onto vehicles below
- Sealant peeling off one face of the joint
- Hardened, cracked sealant on exposed facades
Sites like Orpington Hospital (to the north of Green Street Green) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
What to look for in a quote
- What the guarantee covers, and for how long
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?
- Their approach to joint depth and backing
Why it’s worth doing now in Green Street Green
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Why us?
- Clear, fixed quotes

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Avoid parking heavy plant or pallets on joint lines
- Note which joints were done, when, and with what
- Raise snow-clearing blades over deck joints where possible
- Check joints after long freezing spells
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What sets the cost
What shapes the price:
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- Phasing around occupants
- How accessible the joints are
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

To price the job accurately, we need to understand the site. Useful things to include:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- The product your specification calls for

FAQs: Green Street Green
Is Glebe Farm Business Park, near Green Street Green, within your area?
Yes. We cover Green Street Green and the area around it, including industrial estates, business parks and retail parks such as Glebe Farm Business Park. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing, because the fix differs.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.
