Questions about Northumberland Park

Does your area include sites such as Compass West Industrial Estate, near Northumberland Park?

Yes. Estates, retail parks and business parks around Northumberland Park, Compass West Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Do you take on jobs in Northumberland Park where loading and access are tightly controlled?

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.

Can you fill joints where the arrises have spalled?

We check the edges as part of the survey. Where they have broken away, we will tell you before quoting the filling, so nothing is filled that won’t hold.

Which is better for warehouse joints, filler or sealant?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right and perimeter or movement joints need flexibility. The quote sets out what goes where.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How long before trucks can use the joints?

Cure times vary with the product and the conditions. You will get a reopening time for each area when we agree the phasing.

How we handle floor joint sealing in Northumberland Park

We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Each job is priced from the metres of joint, their condition and the access windows we get, and the quote is fixed before we mobilise. If you have a rough ride across broken joints and dock area joints that have failed first, we can put it right, whatever the surface. Searching for sealant specialists in Northumberland Park? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

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.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Maintenance after handover

A few simple habits keep the new joints working:

  • Start with the dock areas, where joints fail soonest
  • Remind operators to lift rather than drag
  • Respect the cure time before traffic returns
  • Let us know what the floor is cleaned with

We will give you a time before trucks can run over the new joints and it pays to stick to it. In a busy building, barriers keep early traffic away.

Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out so nothing is left to fail.

Building owners, agents and FMs in Northumberland Park

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

We work for building owners and managing agents on everything from one building to a spread of sites around Northumberland Park. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Joints that move: notes for Northumberland Park

London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager. The 3 miles around Northumberland Park take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For an estate such as North Middlesex University Hospital, 0.9 miles to the north-west of Northumberland Park, the joints in ramps, decks and long building elevations all need attention over time. Phasing is what makes joint work possible on busy sites such as Tottenham Commercial Park (less than half a mile east of Northumberland Park): one bay, aisle or car park row at a time. Warehouse floors on estates like Compass West Industrial Estate, under half a mile to the north of Northumberland Park, carry pallet trucks and forklifts over every saw-cut joint.

Northumberland Park is about 1 mile north-east of Tottenham, in Greater London. We cover commercial sites throughout Northumberland Park. Northumberland Park is one of 764 places in Greater London on our list. London is covered too, around 7 miles from Northumberland Park.

Commercial sites across N17 and N18 are covered. Streets here include Love Lane, Park Lane and York Road. We also cover Upper Edmonton (1 mile north-west), Edmonton (1 mile north), South Chingford (1 mile east), Picketts Lock (2 miles north-east) and Highams Park (2 miles east). Further afield, our area takes in London (7 miles south), City of Westminster (7 miles south-west), Marylebone (7 miles south-west), Kensington (10 miles south-west), St Pancras (6 miles south-west) and Shoreditch (6 miles south).

Landmarks near Northumberland Park

We work on buildings around Duke's Aldridge, No.8 Tottenham pub and London Academy of Excellence Tottenham, among other places. Northumberland Park has its own railway station: Northumberland Park (London) station. A little further out are North Middlesex University Hospital (0.9 miles north-west) and Markfield Beam Engine and Museum (1.6 miles south). Green spaces nearby include Pole Hill and Highams Park Lake.

What sets the cost

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

  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Access and working height
  • Working within restricted access windows

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • The site address and postcode

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or send details through our quote form.

What the job involves on each surface

Forklift and pallet-truck routes

Trucks running over open joints wear wheels and shake loads. Filling them gives a smoother run and protects the floor.

Loading bays and dock areas

At loading bays, product choice has to suit the loads, the temperature and the wet. Curing times also have to fit around deliveries.

How a job runs

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. In Northumberland Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. A floor survey records every joint, its edges and what crosses it.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached
  • Let building users know which areas are affected
