Floor joint sealing across Broad Green

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

From enquiry to sign-off

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. All of Greater London is in the ULEZ, and kerbside space in Broad Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. The area is handed back once it has cured enough to take traffic.

Before we start on site

  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed

Floor joint sealing in Broad Green, done properly

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them so the rest of the operation keeps going. We work on forklift and pallet-truck routes, retail and showroom floors and loading bays, and the failures we are asked to look at most are untidy open joints in a retail unit and a rough ride across broken joints. A specialist sealant contractor works differently from a general builder: in Broad Green, that means joint design, primers and backing rod as standard.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Broad Green means thinking about access, loading times and the ULEZ as well as the joints.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Cracks across panels caused by settlement or overload
  • Damaged or worn floor coatings and screeds
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

  • Joints along racking aisles
  • Saw-cut induced joints
  • Loading bays
  • Construction joints
  • Forklift and pallet-truck routes
  • Retail and showroom floors

Different surfaces, different methods

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.

Loading bays and dock areas

We normally work through dock areas a few bays at a time so goods in and out carry on. Tell us your site hours and access windows and we’ll plan around them.

What affects the price in Broad Green

We price every job individually. The things that drive the figure:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Whether the work must be split into stages
  • Distance, for remote addresses

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • Anything awkward about access or site hours

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Slabs, ramps and loading bays in Broad Green

Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager. The 3 miles around Broad Green take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Centres like Whitgift Centre (0.8 miles south of Broad Green) have mall floors and service decks whose joints carry steady traffic. Phasing is what makes joint work possible on busy sites such as Thornton Road Industrial Estate (0.7 miles west of Broad Green): one bay, aisle or car park row at a time.

When to call us in Broad Green

Pallet-truck and forklift wheels concentrate weight on a tiny contact patch. Crossing an open joint, the wheel drops and knocks the opposite arris, and repeated impacts break the concrete away.

What tends to prompt an enquiry:

  • Untidy open joints in a retail unit
  • Old filler gone hard, cracked or loose
  • Open saw cuts full of debris
  • Sealant pulled out along a truck route

In a school such as Elmwood Infant School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

FAQs: Broad Green

Can you work at a site such as Pilton Industrial Estate, by Broad Green?

Yes, sites like Pilton Industrial Estate are within our area, along with the rest of Broad Green. A few photographs and the unit address let us price the work.

Do you work in London buildings with loading restrictions?

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.

What site paperwork can you supply?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

When can forklifts run over new joint filler?

The wait is set by the product’s cure time and cooler floors take longer. Phasing is planned with that in mind.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can the sealant be colour-matched?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What do you need from us to quote?

Send details through our quote form or by email and tell us what runs on the floor. A fixed quote follows that shows the products and zones.
