Floor joint sealing in The Burroughs

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Cost factors for floor joints

Each job is priced on its own details. The main factors are:

  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • How much existing material needs removing

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • Clear photos of the problem areas
  • Any specification or named product
  • Your programme or deadline
  • Anything awkward about access or site hours

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

How we handle floor joint sealing in The Burroughs

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so we’ll tell you if the joint edges need repairing first and leave that decision with you. Most enquiries involve saw-cut joints left open and packed with grit and old filler gone hard, cracked or loose, on construction joints, saw-cut induced joints and loading bays. Whoever orders the work in The Burroughs, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Areas such as a loading bay or car park deck in The Burroughs usually have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

FAQs: The Burroughs

Would you work within a site like BMI Hendon Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Can you work in a London building with booked loading and goods-lift slots?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.

What happens if the joint edges are damaged?

Edge condition is recorded when we look at the floor. Where they have broken away, we will tell you before quoting the filling, so nothing is filled that won’t hold.

How long before trucks can use the joints?

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

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is it normal for joint filler to separate?

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.

Should floor joints be filled or sealed?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is usually right and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.

After the work

Regular inspection catches problems early. Specifically:

  • Keep trucks off new joints until we say they’re ready
  • Make joint checks part of your floor inspections
  • Treat loading bay joints first if they’re failing
  • Photograph any joint that starts to chip

Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time.

Treating joints while the arrises are sound keeps the work simple. After the edges go, repairs come into it, with more downtime and more disruption.

What we’re called out for in The Burroughs

Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen, and a filler placed early can part company with one face.

It’s worth sending us details if you spot any of the following:

  • Trucks and loads jolting over damaged joints
  • Chipped and spalling edges along forklift routes
  • Soft sealant dragged out of trafficked joints
  • Joint fill separating from the concrete

At a retail site such as Brent Cross Shopping Centre, 0.8 miles south of The Burroughs, trolleys, cages and cars run over floor and slab joints all day.

How to choose a sealant contractor

Floors, slabs and movement joints in The Burroughs

Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. At least three named trading, business or retail sites lie within about 3 miles of The Burroughs. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Hospital campuses such as BMI Hendon Hospital (to the north-east of The Burroughs) grow in stages, leaving movement joints wherever new blocks meet old. Phasing is what makes joint work possible on busy sites such as Brent Cross Shopping Park (1.2 miles south of The Burroughs): one bay, aisle or car park row at a time.

The Burroughs is about 2 miles south-east of Burnt Oak, in Greater London. Any commercial site in The Burroughs is covered, whether it’s a single job or part of a planned programme. The Burroughs is one of 764 places we cover in Greater London for floor joints. London is covered too, some 8 miles away.

Business premises anywhere in NW4, NW9 and NW11 are within our area for floor joints. Among the streets we cover are Bell Lane, Eaton Road and Lodge Road. The Burroughs sits on or close to the A41. Just outside The Burroughs, we also work in Hendon (1 mile south-east), Colindale (1 mile west), Brent Cross (1 mile south-east), West Hendon (1 mile south-west) and The Hyde (1 mile south-west). A short drive away, we cover London (8 miles south-east), City of Westminster (6 miles south-east), Marylebone (6 miles south-east), Kensington (6 miles south), St Pancras (6 miles south-east) and Shoreditch (8 miles south-east).

Local landmarks in The Burroughs

We work on buildings around The Claddagh Ring pub, Brampton College and Kisharon College, among other places. The nearest railway station is Hendon station, about 0.8 miles south-west. Nearby you’ll also find Church Farmhouse Museum (under half a mile north) and Brent Cross Shopping Centre (0.8 miles south). For a walk, there’s Parliament Hill and Darland's Lake.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a day or more, depending on the metres of joint and how many zones the floor is split into. For a job in The Burroughs, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. You get a fixed quote with the product and the phasing set out.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  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.

Preparing the site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Point out any areas we must not close

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • A failing floor coating, which is a flooring contractor’s job
  • Cracks across panels caused by settlement or overload
  • Level or flatness problems across the floor

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Where we work in The Burroughs

  • Forklift and pallet-truck routes
  • Saw-cut induced joints

  • Joints along racking aisles
  • Retail and showroom floors

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
