What needs to go. Prepared properly.

Agree who will arrange for services to be taken out of use: the network operator, a qualified installer or another designated professional. Mention known meters, tanks and pipes, including supplies shared with a building that will remain. An empty house is not necessarily disconnected. Obtain the necessary confirmations before work starts and distinguish these tasks from demolition in the quote. Do not cut or dismantle a pipe yourself to prepare for the contractor’s arrival.

Check the assumptions in the quote: substrate thickness, concealed foundations, access and estimated waste quantities. Ask how a difference will be recorded, priced and submitted for your approval before additional work. For renovations, agree who decides whether a newly revealed element stays or goes. If suspect material is found, it needs an appropriate assessment; agreeing an extra charge does not by itself authorise demolition to continue.

Selective demolition

No. Screed is a floor layer, while a slab may form part of the building’s structure. Specify whether the project concerns tiles, screed or structural concrete, and mention underfloor heating or known services. Have the substrate’s composition and role confirmed before removal. Separate layer removal, disposal and preparation for the new floor in the quote; work affecting stability requires a specific assessment.

Selective demolition

Define what goes: furniture, sanitary fittings, finishes, screed, partitions or pipes. Dismantling fixtures, disconnecting services and demolishing substrates are different items. Identify retained elements and installations shared with another room. Have suspect materials affected by removal assessed beforehand; removing tiles may also disturb adhesive and substrate.

Selective demolition

Before fixing dates, identify who handles studies, service disconnection, any hazardous materials and subsequent work. Request a written sequence with a contact for each stage. For a wall opening, coordinate assessment, demolition and reinforcement; for an outbuilding, roofing, structure and connections. The quote must identify included services and those assigned to another company.

Opening walls & removing partitions

Distinguish preparation of the file, work on site and making the premises available again. Checks, any administrative decisions, access and waste removal affect the schedule. Ask for starting conditions, stages and expected constraints rather than timing based only on area. If part remains occupied, specify usable passages and possible interruptions to equipment.

Gather available plans, known dimensions, existing photographs and any surveys. Describe what goes or stays, access and connected services. Include planning decisions already received and their conditions. You can start the discussion without a complete file: simply identify what needs checking without dismantling anything to obtain information.

Define this in the quote: debris removal, retaining or removing the slab, foundations, levelling and protection of remaining parts. Cleared ground is not necessarily ready for building. Specify reinstatement, exclusions and planned waste documents. For interior renovation, distinguish stripping finishes from preparing substrates for the next trade.

Selective demolition

In Flanders, demolition generally requires a permit, with conditional exemptions. Brussels and Walloon rules also require authorisation, subject to applicable exemptions. Have the municipality confirm your case before work. Check environmental obligations too: in Wallonia, a combined permit application is required if both permits are needed.

The sloopopvolgingsplan identifies expected hazardous and non-hazardous waste and prepares selective dismantling. It is compulsory for certain works requiring a permit, depending on their nature and volume. The official page explains the conditions and the exception for a single-family house. That exception does not remove the need to check other site rules.

Volume, access, neighbouring buildings, materials and disposal matter as much as area. A square-metre price alone cannot compare two demolitions. For a house or garage, have foundation and slab removal, waste disposal and any asbestos work specified in the quote.

No. A load-bearing wall contributes to structural stability. A specialist must assess the opening, load transfer and any temporary support before work. Available plans, required dimensions and services passing through the wall help prepare that assessment.

Opening walls & removing partitions

The employer’s work plan provides for removal before demolition. The Code allows an exception where removal creates greater risks for workers than leaving materials in place. Responsible professionals must define the sequence after identifying the materials.

Asbestos & renovation

Specify the floor, stair or lift access and occupied rooms. Identify retained elements, the waste route and co-ownership constraints. This helps define protection and phasing. Remaining in the home must be assessed according to the work; area alone cannot guarantee it. Mention agreed access hours and communal areas to protect. Distinguish protection, passage cleaning and finishing repairs.

Selective demolition

Mention shared walls, connected roofs and common access in your enquiry. Plans and a condition survey can help define the boundaries and protection. A party or load-bearing structure needs specific assessment: demolition, any supports and reinstatement of retained parts must be defined before work.

Opening walls & removing partitions

Before the quote, specify doors, sanitary fittings, bricks or other items you wish to keep. Condition, damage-free dismantling, absence of hazardous substances and storage determine reuse possibilities. Separate dismantling for salvage from demolition and sorting for recycling; not every element can be retained.

Selective demolition

Describe the route between the work area and street: doors, stairs, bends and internal courtyard. Add known dimensions and parking possibilities without moving suspect materials. Access determines equipment, handling and disposal. Feasibility and any occupation of public space must be checked before site arrangements are fixed. Distinguish routes for people, equipment and waste. Mention level changes, covered passages or paths to preserve using information already known.
