Floor joint sealing in Hampstead, done properly

Most industrial slabs are divided into panels by saw-cut joints and construction joints, and each joint line is a weak edge that wheels run over all day. We fill or seal them with a product matched to the traffic and the movement, so the arrises are supported and grit stays out. If you have drivers complaining about joints on a route and loading bay joints breaking down, we can help, on construction joints, saw-cut induced joints and retail and showroom floors alike. Whoever orders the work in Hampstead, the brief is normally 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 Hampstead usually have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

After the work

To get the most from the new sealant:

  • Keep photographs of joints that look like they’re failing
  • Tell us about strong cleaning chemicals before we quote
  • Plan for a top-up on newer floors
  • Clear packed debris from open joints regularly

Normal floor cleaning is fine once the product has cured. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

Building owners, agents and FMs in Hampstead

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Planning a London job such as one in Hampstead starts with access: 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.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. You get a fixed quote with the product and the phasing set out.
  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.

Getting the site ready

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Let us know about inductions and permits

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Why it’s worth doing now in Hampstead

Duct tape or a general builders’ sealant can seem to buy some time. Neither is made to carry wheels and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. In Hampstead, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Why appoint us

  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over
  • 12 months’ guarantee on every job
  • A fixed quote before work starts

Warehouse floors and decks around Hampstead

In London, decks, bays and service yards usually have to keep running, so joints are sealed in sections with each area handed back once cured. Less than 3 miles from Hampstead 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.

Sites like Royal Free Hospital, 0.6 miles east of Hampstead, carry ambulances, deliveries and visitors’ cars over their road and deck joints. Another example is Regis Road Business Park (1.5 miles east of Hampstead), where floors and yards would be done in stages around the occupiers. For estates staff at a university like Regent's University London, which lies south-east of Hampstead, building and paving joints are part of the planned maintenance list.

How the job changes by 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.

Retail and showroom floors

Retail work is phased around trading. Tell us your site hours and access windows and we’ll plan around them.
