What the job involves on each surface
Saw-cut induced joints
A sawn joint left open soon packs with debris and chips at the edges. Filled in good time, they stay narrow and neat.
Construction joints
Construction joints, sometimes called day joints, mark where one pour ended and the next began. They often see more movement than sawn joints and that shapes the choice of filler or sealant.
Floor joint sealing in Blackfen
We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. If you have scruffy, dirty joint lines on a shop or showroom floor and unfilled floor joints collecting dirt and grit, we can help. Facilities teams, main contractors and managing agents in Blackfen tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Areas such as a loading bay or car park deck in Blackfen normally have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For a job in Blackfen, 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.
- A floor survey records every joint, its edges and what crosses it.
- You receive a fixed quote showing products and phasing.
- Old fill and packed debris come out until both faces are sound.
- Dust is vacuumed out and primer applied where specified.
- The joint is filled to its specified depth and trimmed level.
- Zones reopen once cured and the work moves on.
Before we start on site
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email us.

What we’re called out for in Blackfen
Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. Each panel pulls back as it shrinks and the joints open up so a filler put in early may separate along one side.
Any of the following is a good reason to get the joints checked over:
- Cracked and crumbling joint fill
- Joint fill separating from the concrete
- Saw-cut joints left open and packed with grit
- Drivers complaining about joints on a route
Another example is Old Bexley Business Park, 2.6 miles east of Blackfen, where floors and yards would be done in stages around the occupiers.

What happens if it’s left?
Holding off until the whole floor can close can take a long time. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Blackfen: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Can you work on a hospital site such as Eltham Community Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Why has the filler pulled away from one side?
Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. It is typically dealt with by topping up.
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 confirm what’s available for the specified product when we quote.
Do you cover Blackfen?
Yes. We cover Blackfen, and you can speak to us on 01277 525 020 or email a schedule or drawings to get started.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
