If you are looking for a new home and only have a limited budget, you are welcome to use a small trick: If you only limit the search to "land", you will often find objects with residual buildings. This must then be "only" stopped and disposed of, and then the dream house can arise on the new ground. That can work - but it can also go bad. In the cost of demolition and disposal, the devil is often in the detail.

Demolition costs per converted space

Everything starts with the report

Before an old object can be demolished and disposed of, the new owner should get an accurate picture of the situation. In addition, the judgment of an expert is worth more than gold. Only if it is known what demolition costs and disposal costs are pending can a viable calculation be made.

There are two things important to this:

  • buildings
  • construction materials

The building substance indicates which device is required to demolish the object. If necessary, you can tear down a worm-eaten half-timbered house yourself with a sledgehammer. In any case, a concrete garage requires heavy technical equipment, which causes further costs.

Much more important than the question of the building fabric are the materials used . Real bombs can slumber here if you have not informed yourself in advance.

costs

Cost trap insulation and protective materials

Mineral building materials are usually easy to dispose of. Everything made of concrete, bricks, calcareous sand or natural stone can be crushed and used as filling material. Metals are especially grateful when demolishing a home. Under certain circumstances, the new homeowner can properly capitalize on the scrapping of old equipment. Above all, copper and aluminum achieve interesting prices on the scrap market. It is therefore worthwhile to take a close look and to take a close look at the used metals.

Fire prevention materials

The situation is exactly the opposite for materials used for fire protection and thermal insulation. In the case of fire protection materials, a material is particularly critical: if the assessor discovers asbestos, caution is advised. If the asbestos materials are to be demolished and disposed of, there is a legal duty to report! Violations result in severe penalties.

asbestos

In addition, the real estate owner risks that the construction site will be closed and forcibly refurbished - at its cost, of course. Asbestos should therefore not really try to "trick". If a fire wall or roof cover made of asbestos has been detected, you just have to bite into the sour apple. Removal and disposal of these materials is reserved for certified specialist companies only. But the real estate owner has the security of completely correct and legal disposal of his problem substances.

polystyrene

Polystyrene (polystyrene), which was used as standard only a few years ago, has now turned out to be a real cost-bomb. Its disposal has become so expensive that even construction companies were driven into bankruptcy over the costs. Here, as the landlord, you have to be especially careful when it comes to demolishing old buildings .

Our tip is already at this point: Remove the old insulation materials as thoroughly as possible. Once Styrofoam is detected in mineral debris, the disposal costs multiply multiply. Therefore, pay only what you have to pay by separating your demolition with great care.

You have to expect these costs

But even if the house is in an ideal condition for the demolition, the demolition costs are surprisingly high.

Assuming that the house ...

  • asbestos-free
  • easy to remove
  • without polystyrene
  • detached
  • easy to access
  • without a cellar

... is, but then come tens of thousands of euros for the demolition of a house together. The prices presented here are only a rough guide . They are stated as "cost per square meter". This allows an estimate to be extrapolated to the object.

  • Planning: about 1000 euros or 10 euros per square meter
  • Preliminary work: about 25 euros per square meter
  • Demolition: about 100 euros per square meter
  • Earthwork: about 40 euros per square meter
  • Disposal costs: about 35 euros per cubic meter

planning

No demolition without planning

The planning is very important for the demolition. It not only determines the building substance and the residues to be disposed of. Above all, planning in terms of statics is very important. A house must be demolished exactly to plan . This is the only way to avoid an uncontrolled collapse. A Chaos Breakdown not only complicates the demolition work, it also makes the disposal of the residues unnecessarily complicated. In addition, a collapse of the house is always a great risk of injury to others.

Preliminary work

Preliminary work keeps the costs in check

Before demolition comes gutting . First, all the moving goods must be removed from the house: old furniture, carpets, curtains, household goods and loose debris that has accumulated over the years.

Then all installations are removed:

  • Hang lamps
  • Remove switch
  • Tearing pipes and pipes out of the wall
  • Disassemble sink
  • Remove doors and windows
  • Dismantle satellite dishes
  • Disassemble the radiator
  • Remove heating system in the basement
  • Remove solar modules from the roof

Then the foreign substances are taken out of the house.

That can be:

  • Wood of wainscoting and fixtures (stairs)
  • Insulation material from false ceilings and rafters
  • drywall
  • roofing
  • Floor and ceiling linings made of laminate or MDF

Although this work is not difficult, it does decide considerably on the costs of disposal . The cleaner these materials are separated, the lower the bill from the recycling center. It really is worthwhile to preserve the most embarrassing order here.

Demolition of the shell

The demolition of a gutted raw building usually requires heavy equipment. A medium-sized crawler excavator is the least needed.

Important when choosing the demolition excavator are two factors:

  • reach
  • Load with fully extended boom

The reach of the excavator must reach beyond the roof of the demolition house. Otherwise the excavator is simply useless for this property.

When the boom is fully extended, the excavator must have sufficient payload and stability. Otherwise it may happen that it falls over when lifting the ridge beam. Ideal here are construction machines with additional supports. Ideal is the use of a real demolition excavator. This not only has the carrying capacity and the technical requirements. He is also equipped with the appropriate tools, which are designed especially for the demolition of houses.

Family houses

For smaller houses you can find with a little luck very cheap devices. Completely equipped demolition excavators with a range of 8 meters can be hired from just 400 euros per day. But if that is not enough, it can quickly become much more expensive.

The self-tearing certainly makes the layman a lot of fun. It is cautioned. The demolition planning with statics calculation must be available in any case, to which must necessarily be kept. In addition to the excavator driver, another helper is required, who constantly fogs the break-off point with water. This reduces the dust development considerably.

Nevertheless, our recommendation is to leave the demolition of a house to a professional company . Even if it costs several thousand euros, so the homeowner saves a lot of trouble and work.

earthwork

Earthworks are part of it

The house stands on a foundation. This too has to be removed from the earth and disposed of. The resulting excavation is filled in and the terrain is leveled. So you get a clean result. Therefore, the earthworks at the demolition costs are easy. Otherwise you will have a lunar landscape afterwards, with which nobody can do anything.

disposal costs

Now it is getting expensive

The cost of disposal is considerable. The variety of building materials is a real cost driver. Here is an overview of which disposal costs per type of material must be calculated.

  • Clean, dry old wood (eg from old trusses): 45 euros per ton
  • Old wood with protective coating: 110 euros per ton
  • Clean building rubble from mineral residues (brick, sand-lime brick, concrete): 30 euros per ton
  • Rubbish contaminated with waste: 170 Euro per ton
  • Asbestos, also with asbestos contaminated debris: 170 euros per ton
  • varietal plasterboard: 50 Euro per ton
  • Glass wool: up to 250 euros per ton
  • Polystyrene: up to 400 euros per ton

savings

Save money wherever possible

In sum, for a normal single-family home loosely an amount of 20, 000 euros for demolition costs arise. For apartment buildings, the demolition costs increase very quickly. Alone the rent for a larger excavator beats with several hundred euros per day more book.

It is therefore important to proceed in a planned manner and to use all possibilities of saving. Even if so much is given away as possible, the demolition costs can be significantly reduced. If even a few things can be sold, so much the better.

Things that customers usually find sooner or later are the following:

  • Window, complete with frame (if intact)
  • Doors, ideally with frame
  • Washbasin, shower partitions
  • Lamps, switches
  • Parquet, wooden ceilings

TIP: Getting rid of unwanted material is especially easy when it is offered for self-depletion. The classifieds on the Internet are the ideal marketplaces.

Bonanza old brick

What has proven to be a real recycling miracle in recent years is old bricks. They are often used by decorators and horticulturists to create sidewalks or small walls. In garden design, the "ruin corner" is the latest craze. Old bricks are the perfect building material for these cozy interiors .

When the opportunity presents itself, the old stones should therefore not be disposed of, but cleaned and sold again. The bricks are now traded for over a euro apiece. If then the saved disposal costs are added, makes the clever Abbruchwillige double the profit - after all, weighs a range of bricks 1.5 tons.
