A major home renovation or office extension often requires a new stairwell opening. This may be to relocate an existing staircase or install a completely new one to an upper floor. On this page, you can read how this demanding job is carried out and why Sloop Concurrent's experts are the best choice for the project.

Creating a stairwell opening in concrete or another stone material

Creating a stairwell opening usually involves cutting through concrete or another hard stone material. Sloop Concurrent owns modern, advanced equipment and tools to carry out this demanding work successfully. Our many years of experience have helped us develop an efficient technique used to complete countless jobs successfully. Many staircases have been moved or installed thanks to the accurately cut stairwell openings created by Sloop Concurrent.

Using the structure as a guide

Moving a stairwell opening or adding a staircase in a large building requires careful assessment. The project must never compromise the structure of the house or building. A building's load-bearing structure is the foundation on which everything depends. Weakening the structure of your house or building can cause damage such as cracks in walls or doors and windows that stick. In extreme cases, irreversible damage such as collapse can occur! That is why Sloop Concurrent uses your home's structure as the guiding principle for the project. We examine the building drawings and, where necessary, our regular structural engineer prepares structural calculations. Do these show that a full or partial replacement structure is needed to create the stairwell opening? Sloop Concurrent's specialists will then handle everything efficiently and smoothly from start to finish.

Why have Sloop Concurrent create your stairwell opening

Concrete cutting is one of the specialities of Sloop Concurrent's skilled professionals. Besides our proven experience and professionalism, there are several other reasons why Sloop Concurrent is the best choice for concrete cutting:

Value for money

Sloop Concurrent uses standard rates for a number of set services. The larger the project, the higher the price. We explain this in a detailed, no-obligation quotation. It sets out the specific work and associated prices and gives an immediate indication of the project's duration. We are therefore transparent about both our prices and the estimated time required!

Tidy handover

Concrete cutting usually produces a fair amount of rubble and dust. Sloop Concurrent's tradespeople gather the rubble in an agreed location and leave the work area tidy and swept clean. We can also take the rubble away if required, saving you time and effort. Please state this clearly when requesting a quotation so we can allow for it.

Cost of creating a stairwell opening

Several factors have a major impact on the cost of creating a stair opening. The equipment and tools required, the preparation work and the scale of the project have the greatest influence. It may also be necessary to have structural calculations prepared and install a replacement supporting structure based on them. This is not always necessary and depends on the situation. It is therefore very difficult to give an average cost for cutting a stair opening.

Tidy working through dust reduction and rubble removal

Cutting concrete to create a stair opening can release a considerable amount of dust. We use a water system to reduce this. This means wetting the area being cut, with water running over the walls and floor. As well as limiting dust, the water cools the diamond saw. The water generally dries within a few hours, allowing subsequent work to resume quickly. For an additional charge, the water can also be removed immediately; this requires more labour and is therefore slightly more expensive.

Cutting a stairwell opening produces a fair amount of rubble as well as dust. By agreement, we can collect this concrete in a location you specify. Once the job is complete, you can dispose of the rubble yourself. For a small additional charge, we can remove it efficiently, quickly and professionally. A convenient option!

Asbestos must always be considered when demolishing structures. We therefore hold dNAA certification, which allows us to remove asbestos. We do so safely and responsibly.

Frequently asked questions about creating a stairwell opening

Who determines the position and dimensions of the stairwell opening?

The staircase supplier and structural engineer must agree what opening is usable and structurally possible. Besides the floor, factors include the stair layout, headroom and connections. Have a suitable design prepared first.

Can a stair opening be cut in an existing concrete floor?

That depends on the floor type and structure. Have the drawings and site assessed before disturbing reinforcement or prestressed components. A structural engineer determines whether strengthening and temporary support are required.

What happens to the concrete that is cut out?

How the sections will be supported, moved and removed is determined in advance. Their weight, access and the space below are important factors. Have waste removal and any lifting equipment included in the quotation.

What preparation can I do myself?

Gather the drawings and clear the agreed access route for deliveries. Do not make exploratory holes or remove anything without consultation. Follow the agreed preparations for electricity, water, protection of belongings and access.

What determines the price of a stairwell opening?

Dimensions, floor type and thickness, structural provisions, cutting, waste removal and repairs together determine the price. A cutting price alone is therefore not a complete quote for a stairwell opening. Read more about concrete cutting costs.

Preparation → execution → handover

Concrete cutting and creating a stair opening: the process in 12 steps

Creating an opening in concrete requires preparation of the structure, services and disposal arrangements. These steps describe coordination with professionals, not how to cut a load-bearing floor yourself.

Illustrated story created with AI. These are not photographs of a completed project. Read the twelve steps below; technical details are designed for each project. View the larger illustration.
AI illustration in twelve numbered scenes: concrete cutting and creating a stair opening, from preparation and investigation to professional execution and handover.
  1. Discuss the purpose of the opening

    The proposed staircase, installation or passage determines which design information is needed.

  2. Collecting structural information

    Drawings, available floor information and details of previous alterations are provided to the specialist.

  3. Investigating building services and materials

    The relevant tradespeople determine what additional investigation of services, reinforcement and construction build-up is needed.

  4. Planning support and waste removal

    The structural engineer and site supervisor coordinate the opening, supports, work sequence and safe handling of sections.

  5. Recording the scope and procedures

    Required permissions, cost components, finishing and responsibilities are checked.

  6. Setting up work zones

    The space on the other side of or below the opening is also included when planning and cordoning off the work area.

  7. Check the conditions for starting work

    The specified measures and safe access are checked before cutting begins.

  8. Carry out professional cutting work

    The team follows the project plan, using appropriate dust or water control and protective equipment.

  9. Remove sections in a controlled manner

    Concrete is moved using the planned supports and transport equipment, away from unauthorised people.

  10. Removing water, slurry and waste

    The agreed collection and disposal arrangements prevent debris from spreading uncontrollably through the building.

  11. Check the opening and protective barriers

    The opening is checked and remains safely guarded until the next stage of work takes over.

  12. Handover for the next stage of work

    The staircase manufacturer or installer receives the relevant dimensions, points to note and project documents.

This information is for clients. The professionals involved adapt the work and safety measures to the property. Do not work on load-bearing elements, unidentified services or materials suspected of containing asbestos yourself.
