Introduction: why and when is dismantling of a metal garage required?
Dismantling an iron garage is a task that owners face when moving, selling a property, or upgrading storage. Unlike wood or brick structures, metal garages require a special approach: their framing system, bolting and sheet weight pose unique challenges. Errors during dismantling can lead to panel deformations, injury or loss of fasteners, which will complicate reassembly.
The service life of a metal garage with proper operation reaches 20–30 years, but even durable structures made of corrugated sheets or sandwich panels require careful handling. For example, rust on bolts or warping of the frame after wintering can turn disassembly into a painful process. This article will help you avoid typical problems: from selecting tools to loading items to transport without damage.
Pay special attention legal nuances: If the garage is located on the property of a garage cooperative, board approval for dismantling may be required. Also check whether the structure is listed in Rosreestr as a permanent structure, this affects the deregistration procedure.
Preparing for Disassembly: Tools and Safety Precautions
Before starting work, draw up dismantling plan, taking into account the sequence of disassembly (usually from the roof) and the storage location of the removed elements. You will need:
- 🔧 Set of open-end and spanner wrenches (dimensions
10–19 mm) - 🔨 Impact drill or impact wrench with an attachment for rusty bolts
- 🧲 Magnetic holder for fasteners (so as not to lose the nuts)
- 🪜 Stepladder or stable ladder (height from
2.5 m) - 🧤 Gloves with anti-vibration coating (protection from cuts on metal)
Critical error: ignoring protection measures. According to statistics, 30% of injuries during garage demolition are caused by falling tools or sharp edges of sheets. Be sure to use safety glasses and helmet, if you work in pairs, even a light sheet of corrugated sheet falling from a height can lead to serious injuries.
Check the weather: wind over 10 m/s makes working at height dangerous, and rain increases sliding on metal. The optimal time for dismantling is the morning, when the dew has evaporated, but the heat has not yet deformed the sheets.
Disassembly order: where to start and how to avoid mistakes
Start with removal of internal filling: shelves, racks, drawers. Even an empty garage may contain hidden fasteners - check corners for anchor bolts, driven into the foundation. If the garage was on strip base, its dismantling will require a separate approach (more on this in the next section).
Basic disassembly sequence:
- Roof: remove sheets from the windward side to avoid “sailiness” of the structure.
- Walls: Loosen the bolts from top to bottom, starting with the end panels.
- Frame: Disassemble into sections, marking the elements with a marker (for example, “Front left pillar”).
- Foundation: If the garage was on blocks or slabs, they can be left for a new building.
Tip: take pictures of each step with your phone - this will help with reassembly. It is especially important to record jib location (diagonal struts), since their incorrect installation will lead to distortion of the structure.

Difficult points: rusty bolts, deformed sheets and foundation
The most common problem is stuck bolts. Do not try to tear them off by force: this will lead to the edges breaking or the fastening breaking. Instead:
- 🔥 Heat the bolt gas burner (up to
200–300°C) and immediately try to unscrew it. - 💧 Process the connection WD-40 or brake fluid, wait 15–20 minutes.
- ⚒️ Use bolt cutter or angle grinder for a neat cut (leave 2-3 mm for gripping with pliers).
If the corrugated sheets are bent during dismantling, they can be straightened rubber mallet on a flat surface. Severe dents (deeper 5 mm) make the sheet unsuitable for reuse - it is better to scrap such specimens.
The situation with the foundation is more complicated: concrete blocks weigh 20–40 kg will have to be extracted using scrap or hydraulic jack. If the garage was on pile-screw foundation, the piles can be unscrewed pipe wrench (2-3 people will be required).
What to do if the bolt breaks inside the nut?
Use extractor (special conical tap) or drill out the remaining bolt with a drill 0.5–1 mm smaller than the thread diameter. After this, cut the new thread with a tap. If the nut is in a hard-to-reach place, you can weld a larger nut to the piece of bolt and unscrew it.
Transportation and storage: how not to lose parts
After disassembly the question arises: how to move a garage no damage? The best option is rent flatbed truck with body length from 4 m. Place the elements in the following order:
- Roof and wall sheets - vertically, lay cardboard or foam between them.
- Frame pipes - tie into bundles of 3-4 pieces.
- Fasteners - pack in separate bags with tags (“Corners”, “Roof”, “Walls”).
A dry room or shed is suitable for storing a disassembled garage. If you plan to assemble the structure in a few months, treat the metal anti-corrosion spray (for example, Rust-Oleum). Details from galvanized steel less susceptible to rust, but they should also be ventilated once every 2-3 months.
Tip: if the garage was dismantled for sale, photograph all the elements on a white background with a tape measure - this will increase buyer confidence. Specify in the ad exact configuration (for example: “6 sheets of corrugated sheets S-8 1150×2000 mm, frame made of profile pipe 40×40 mm»).
If you are transporting the garage over a long distance, wrap the joints of the frame pipes stretch film - this will prevent scratches and loss of small parts.
Legal aspects: what needs to be completed before dismantling
If the garage is located on garage cooperative lands, check the organization's bylaws: some require 10-14 days written notice of dismantling. In case individual plot (individual housing construction, private household plots) it is enough to follow two rules:
- Make sure that the garage is not listed in EGRN as a real estate item (check through Rosreestr).
- If the garage is connected to the electrical network, order shutdown in energy sales (unauthorized cutting of wires is fraught with a fine of up to
30 000 ₽).
After dismantling the permanent garage (with foundation), it may be necessary deregistration. To do this, submit an application to the MFC with a passport, land documents and an act of destruction of the object. The procedure takes up to 18 working days.
⚠️ Attention: If the garage was built without permission (unauthorized construction), its dismantling does not cancel fines for past violations. Before starting work, check the status of the property with your local administration.
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when dismantling metal garages. Here are the most common:
| Error | Consequences | How to avoid |
|---|---|---|
| Disassembly without an assistant | Falling sheets, injuries | Minimum 2 people: one supports the sheet, the second unscrews the bolts |
| Using a grinder to cut bolts | Damage to the threads in the frame | Use only bolt cutters or hacksaws. |
| Storing fasteners in one pile | Lost nuts, confusion during assembly | Sort by packages with signatures (“Roof”, “Corners”) |
| Ignoring the wind | Blowing of sheets, deformation of frame | Work in calm weather or use safety ropes |
Another typical problem is incorrect marking of parts. For example, mixed up right and left corner posts will cause the garage to be skewed after assembly. Solution: Apply tags paint or adhesive tapes different colors even at the dismantling stage.
The most dangerous mistake is dismantling the roof alone. A corrugated sheet weighs 15–25 kg, and falling from a height of 2–3 m can lead to serious injuries. Always belay with ropes or work with a partner.
FAQ: answers to frequently asked questions
How long does it take to dismantle a standard 3x6 m garage?
When working together - 6–8 hours (excluding foundation). If the bolts are rusty or the garage has been standing for more than 15 years, the time may increase to 2 days. Tip: start in the morning so you have time to complete dismantling the roof before evening.
Is it possible to dismantle a garage in winter?
Technically yes, but this complicates the process: the metal becomes brittle at temperatures below -10°C, and snow on the roof adds weight. If there is no alternative, use propane torch to warm the bolts and clear the sheets of ice plastic (not metal!) scraper.
What to do with the foundation after dismantling?
Options:
- Leave it for the new garage (if it's the same size).
- Disassemble into crushed stone (concrete blocks are crushed jackhammer).
- Fill with sand and compact (if you plan to have a lawn or path).
Remember: deletion pile foundation requires special equipment (for example, backhoe loader).
How to estimate the value of scrap after disassembly?
The price depends on the type of metal:
- Corrugated sheet:
8–12 ₽/kg(galvanization is more expensive). - Profile pipe:
15–20 ₽/kg. - Foundation reinforcement:
5–7 ₽/kg.
The exact weight can be calculated from rolled metal tables or weighed at car scales (the service costs 200–500 ₽).
Should you dispose of your old garage in an environmentally friendly way?
If the design has asbestos-containing sheets (rare, but found in old garages), they should not be thrown into a landfill - required special recycling through licensed organizations. Regular scrap metal is handed over to collection points without restrictions. Tip: check the sheets for availability bitumen waterproofing — it must be removed before delivery.
