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

Floor joint sealing in Edmonton, done properly

Before quoting, we look at what the floor is telling us: joint widths, whether the joints are still opening, what runs over them and how the edges have held up. From that we choose between a semi-rigid filler and a more flexible sealant, area by area where it needs to be. The enquiries we see most involve old filler gone hard, cracked or loose and failing joints at loading bays and dock doors, across forklift and pallet-truck routes, joints along racking aisles and retail and showroom floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Edmonton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Maintenance after handover

After handover, a little attention goes a long way:

  • Sweep debris out of open joints until they can be filled
  • Keep trucks off new joints until we say they’re ready
  • Walk the main routes and inspect joint lines on a regular cycle
  • Record damaged joints with a photo and a location

Young concrete carries on shrinking, so some fillers part slightly from one face. That is common and is normally dealt with by topping up once the slab has settled down.

Every vehicle on a busy aisle hits a damaged joint. Sorting it early looks after your equipment as well as the slab.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Planning a London job such as one in Edmonton starts with access. Give us the hours we can be on site and we’ll schedule to suit.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

What we need from you

  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space
  • Tell staff and tenants when we will be in

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

How the quote is worked out

These are the things that shape the price:

  • Which sealant the job calls for
  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • How much existing material needs removing

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 you will have a fixed figure to work with.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • The product your specification calls for

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Your questions answered

Does your area include sites such as Edmonton Green Shopping Centre, near Edmonton?

Yes, sites like Edmonton Green Shopping Centre are within our area, along with the rest of Edmonton. To start, just phone 01277 525 020 or email the details over 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. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Is Edmonton in your area?

Yes. We take on work across Edmonton, with one number for every area we cover.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Is the floor joint work guaranteed?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

Where floor joints take the most wear near Edmonton

Less than 3 miles from Edmonton there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. 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.

Another example is Dominion Business Park, 0.8 miles to the east of Edmonton, where floors and yards would be done in stages around the occupiers. Schools like Brettenham Primary School often have long brick elevations with movement joints that age quietly. A campus such as University of Portsmouth Walthamstow Campus, 3.3 miles south-east of Edmonton, has long runs of movement joint in its buildings, decks and paving.

Edmonton is about 9 miles north-east of City of Westminster, in Greater London.

Further afield, our area takes in London (9 miles south), City of Westminster (9 miles south-west), Marylebone (8 miles south-west), Kensington (10 miles south-west), St Pancras (7 miles south) and Shoreditch (7 miles south).

Leave it or put it right?

A floor coating laid over open joints soon cracks along the joint lines. Joints need their own treatment, whether or not the floor is coated. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What you get with us

  • One number for every site we cover
  • Fully insured, including public liability cover

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Unstable slabs moving under traffic
  • Uneven floors that need grinding or levelling
  • A failing floor coating, which is a flooring contractor’s job

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Joints and surfaces we work on

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

How the job changes by surface

Loading bays and dock areas

Joints at dock doors need a product that copes with the traffic and the conditions. Phasing is planned around your delivery schedule.

Saw-cut induced joints

Induced joints are sawn into a new slab to control where it cracks. They start narrow and widen as the concrete dries, and on truck routes they need a filler that supports the edges.
