There are many reasons to tear down a house. Maybe you’re simply clearing the way for new construction or there are complex structural issues that would be more expensive to fix than it would be to start over. Whatever the motivating factors are, demolishing a house is a big job that requires a clear plan.
Demoing a house involves two basic approaches: deconstruction and demolition. Deconstruction is the process of removing useful materials by hand, preserving and repurposing resources for later use. Demolition, on the other hand, means the utter destruction of the building, usually with heavy machinery. The debris is often hauled away as construction waste afterwards.
When you’ve decided to demolish your house, it’s time to start planning out your project. There are several preliminary factors to address and preparations to make, as well as an assortment of tools you’ll need. Hand tools are useful for deconstructing the interior of the house, while heavy machinery is better suited for bringing down the structure itself after the interior has been cleared out.
If you own and have fully paid off your home, this step won’t be necessary. However, if you still owe a bank or mortgage lender, you will need approval before proceeding with a demolition project. Your lender could also help you secure financing for demolition and rebuilding efforts.
Before tearing your home apart, you’ll want the inside to be completely empty. Throw away, donate or store any furniture, fixtures, decorations, appliances and possessions before proceeding.
Make sure all water, electrical and gas lines running to the structure have been shut off and safely capped. Contact your providers for this step – they may need to send service personnel to your house to ensure all utilities are fully disconnected properly.
“Know where the water shut off is before doing ANY plumbing work. Turn off breakers and even the main power when doing electrical work. Don’t think you know more than you do. It always costs more to learn that way.”

Naturally, destroying or deconstructing a house leads to a substantial amount of debris. An easy way to tidy up after a home demolition project is to use a roll off dumpster and have the junk hauled away. It’s best to schedule your container rental in advance so it arrives in time for your project, especially if you’re renting additional equipment.
Gather Equipment for Home Demolition
Once you’ve gathered the tools you need to deconstruct the interior, it’s time to get started with the next steps. First, we’ll explain how to deconstruct the interior of your home, remove belongings and salvage useful materials. Then, we’ll move to the exterior demolition phase, in which you’ll use heavy machinery to knock down the structure entirely.
Home deconstruction is a labor-intensive process that often comes before complete demolition in an attempt to salvage usable materials from the structure. It also clears the way by removing obstacles and supporting beams from the interior of the house. The best way to go about a home deconstruction project is to tackle one room at a time, starting with the upper floor, if applicable. Here are some basic guidelines to get started.
When the room has been cleared of furniture and fixtures, it’s time to move on to the walls and the sub-structures behind them.
“Many homeowners can put sweat equity into their remodeling projects, and this can be accomplished by handling some of the demolition themselves. Cabinetry, floor covering, trim and wall coverings are the easiest materials to remove without being a skilled laborer. When it comes to removing walls, there is invariably wiring and ductwork, which can be concerning. It is also important to be able to identify bearing vs non-bearing walls. If [you] have no idea, it is best to leave it to the professionals.”

Copper wire and scrap metal from pipes can be sold or recycled after you’ve finished your home deconstruction. Carefully use your reciprocating saw or ratcheting tube cutter to cut through the pipes and separate metals. Cut the pipes and tubes into smaller sections for easier disposal if you’re not planning to re-use them. Otherwise, attempt to cut large sections that can be kept and repurposed later.
Pro-Tip: The electricity in the structure should already be shut off by this point, but be sure to test wires with a voltmeter before attempting to remove them with your wire cutting pliers.
Use a screwdriver to unfasten door hinges and remove it from the door jamb. The jamb itself can be knocked out of the door frame with a hammer. Once uninstalled, doors in good condition can be sold to building supply businesses or donated to charities such as Habitat for Humanity’s ReStore.
When all construction materials in one room have been removed, move on to the other bedrooms and hallways. Collect piping and wiring along the way and salvage any decorative fixtures as you’re able, including ceiling fans and lighting systems.
Unlike bedrooms and hallways, bathroom demolition involves several more complicated deconstruction tasks, including the removal of sinks, bathtubs and other fixtures. Keep in mind that if these fixtures are removed intact, they can be used again in the future.
After the bathroom has been cleared of belongings and the fixtures have been uninstalled, get to work removing the flooring materials and deconstructing the walls as outlined above.
Pro-Tip: Make sure you’ve used the main shutoff valve to turn off all running water in the bathroom.
These areas of the house are likely to have specialized fixtures like sinks, washers and driers, that you’ll want to take the time to disconnect and uninstall properly. Then, you can go about removing cabinets, taking apart walls and tearing up the floors. These cabinets can be reclaimed as scrap wood or even repurposed in a new house if removed intact.
Similar to the bathroom deconstruction process, approach kitchen demolition carefully to safely remove all fixtures and preserve working appliances for reuse.
After the refrigerator, oven and other appliances have been removed, move on to the countertops. These can be taken apart by using a chisel to cut through the caulking material and separate the counter from the wall. A pry bar can then be used to pull the countertop away from the cabinet underneath.
When the countertops have been removed, you’re free to turn your attention to the cabinets, wall tiles and flooring material. If removed carefully, hardwood floor panels can be recycled or salvaged, similarly to your kitchen cabinets. Linoleum is more difficult to reuse, but it’s biodegradable and can be recycled or composted easily.
Now, let’s dive into the main event.
When you have demolition equipment at your disposal, tearing down your house is a relatively simple process. Here are the basic steps to follow.
At this point, the house should be ready for wrecking. If you’re renting your demolition equipment, rental companies can recommend the right type of machinery for the job and may even offer training.
Before using heavy machinery to demolish your house, you’ll want to establish a safety perimeter around the job site with signage, barriers and caution tape.
Generally, a good approach is to use the excavator’s arm to cave in the house’s roof first. This reduces the risk of the building toppling over and causing injury. Then, work your way down by knocking over each wall and caving in each floor. Reduce risk while demolishing the house by pushing against the structure so debris doesn’t fall toward you.
Continue until every floor and wall is leveled. This phase of the process can take several hours, depending heavily on the size of the house and materials used in its construction.
Pro-Tip: Goggles and masks are highly recommended precautions to keep dust out of your eyes and mouth.
After the house is demolished, it’s time to transport the debris into your roll off dumpster. This can be done in several ways, but using your heavy equipment is a popular and effective method. Most hydraulic excavators and backhoes can be used to scoop and deposit debris into containers for easy disposal.
Alternatively, if your excavator doesn’t have the right arm attachment to lift debris, a bulldozer can be used to push the debris closer to your roll off dumpster, while wheelbarrows can help transport smaller amounts at a time. The debris can then be wheeled into your container or loaded manually.
Be sure to use work gloves if handling debris by hand. Tools such as pry bars, rotary hammers, masonry drills and sledgehammers can be used to break large sections into more manageable sizes.

After the debris is cleared away, the ground around the structure will need to be graded and leveled off. Consider hiring professional demolition and excavation experts to handle this step.
Do you have some unanswered questions about how to plan a home demolition project? Get some insight here.
Bringing in a home inspector to review your home before planning a demolition project is a wise precaution to take. A professional will tell you if your home was built with potentially harmful materials like lead paint or ceiling tiles and insulation made with asbestos, which should be mitigated before home demolition can move forward.
Chances are, yes. Most cities, counties and states have specific sets of laws governing DIY home demolition. Your best bet is to reach out to your local government for information. A city legal director or zoning official can tell you what permits you will need and how to get them. It’s important that these guidelines are followed to ensure your home isn’t demolished in an unsafe or irresponsible way. It also saves you from falling victim to fines or legal action.
The national average cost to demolish a house is $3,000 – $35,000. This figure factors in the cost of professional labor, which may not be a consideration if you do all the work yourself. Another major cost in this process is the rental and use of heavy demolition equipment. Prices for these rentals vary around the country so the price tag of your project may differ.
In most cases, demolishing a house requires heavy machinery such as an excavator or bulldozer, which can be rented from a licensed dealer. Many equipment rental companies require a certificate of training before they will rent to a homeowner to ensure safe operation. Some rental companies offer in-house training for potential customers as well. If you don’t have the time to get certified, consider hiring a professional instead.
By tearing down a house yourself, you’ve given yourself a wealth of useful skills that can be put into action in a wide variety of ways. Consider moving on to other structures on your property you no longer need, like your tool shed or patio.
