You’ve made the decision. Your property is getting demolished, the permits are approved, and the crew is scheduled to arrive next week. Now comes a question most homeowners don’t think about until the last minute: what do I actually need to do before the demolition crew shows up?
Proper preparation makes an enormous difference in how smoothly your demolition project goes. When homeowners take the time to prepare their property correctly, projects stay on schedule, costs stay within budget, and everyone avoids unnecessary headaches. When preparation gets rushed or overlooked, delays happen, surprise costs pop up, and what should have been straightforward becomes complicated.
I’ve worked with hundreds of homeowners throughout Seattle preparing properties for demolition, and I can tell you the difference between well-prepared sites and poorly prepared ones is dramatic. Let me walk you through exactly what you need to do, step by step, to get your property ready for demolition day.
Start with a Final Walkthrough: Documenting Everything
Before you do anything else, walk through your property one last time with a camera or smartphone and document everything. Take photos of every room from multiple angles. Capture details of fixtures, built-in features, and anything that might have value or significance.
Why does this matter? First, if you’re planning to salvage anything, photos help you remember what was there and communicate with salvage contractors about what you want removed before demolition. Second, for insurance purposes, having documentation of what existed before demolition protects you if any questions or disputes arise later. Third, if you’re sentimental about the property, photos preserve memories that will be gone once demolition is complete.
Pay special attention to utility locations during your walkthrough. Note where electrical panels are located, where water shutoffs exist, where the gas meter sits, and where sewer cleanouts are positioned. This information helps the demolition crew work more efficiently and safely.
Document the surrounding area too. Take photos of neighboring properties, existing landscaping, driveways, sidewalks, and anything else adjacent to the demolition site. If any disputes arise later about whether demolition work damaged something nearby, you’ll have before photos proving the condition beforehand.
Remove Everything You Want to Keep
This seems obvious, but you’d be amazed how often homeowners leave valuable or sentimental items in buildings being demolished. Once demolition begins, everything inside gets destroyed or buried under rubble. There’s no going back to retrieve something you forgot.
Start by removing all personal belongings from the structure. Go through every room, every closet, every cabinet, and every storage area. Check the attic, the basement, the crawl space, and the garage. Look in places you haven’t opened in years because that’s often where forgotten items hide.
Appliances that still have value should be removed and either sold, donated, or moved to storage. Refrigerators, stoves, dishwashers, washing machines, and dryers can often be donated to organizations like Habitat for Humanity if they’re in working condition.
Fixtures with salvage value are worth removing before demolition if you have the time and capability. Vintage light fixtures, period-appropriate hardware, quality faucets, and unique architectural elements can be sold through salvage companies or donated for tax deductions. Prime Demolition in Seattle works with local salvage organizations and can help coordinate removal of items worth saving, but this needs to be arranged before demolition day.
Don’t forget about outdoor items. Garden tools, decorations, furniture, grills, planters, and anything else you want to keep needs to be removed from the property entirely. Once heavy equipment starts moving around, anything left on site is likely to get damaged or destroyed.
Clear the Area Around Your Property
Demolition equipment is large and needs room to maneuver. Creating clear access makes the crew’s job easier and keeps your project on schedule.
Start by removing any landscaping elements near the structure that you want to save. Shrubs, small trees, decorative rocks, and garden beds directly adjacent to the building should be relocated or removed. The demolition process creates vibration and flying debris that can damage nearby landscaping.
Clear your driveway and any parking areas near the property. The demolition crew needs space for their trucks, equipment, and dumpsters. They’ll typically need access to multiple sides of the building, so providing as much open space as possible helps them work efficiently.
Remove or relocate any outbuildings, sheds, or structures that aren’t part of the planned demolition but sit close to the area where equipment will be operating. Even if these structures aren’t being demolished, they can be damaged by falling debris or accidentally bumped by heavy machinery.
Check for and mark any underground utilities that might not be obvious. Septic systems, underground oil tanks, irrigation lines, and private utilities should be clearly marked so the crew knows where they are. Most professional demolition contractors call for utility locates before starting work, but having your own knowledge of underground features helps avoid surprises.
Clear a path for heavy equipment to access your property. If the demolition crew needs to drive across your lawn or through tight spaces to reach the demolition site, remove any obstacles like fencing, gates, or decorative features that might be in the way.
Secure and Disconnect All Utilities
This is absolutely critical and is typically handled in coordination with your demolition contractor, but you need to understand what’s involved.
Electrical service must be completely disconnected before demolition begins. Contact Seattle City Light to schedule disconnection. They’ll send a crew to physically disconnect and remove the electrical meter. Keep the disconnection notice they provide because you’ll need it for permit documentation.
Water service needs to be shut off at the meter. Seattle Public Utilities handles this disconnection. They’ll turn off service and cap the line. Make sure this happens before demolition day because water lines can create hazards if they’re severed during demolition while still under pressure.
Natural gas service must be disconnected and capped by Puget Sound Energy or your gas provider. Gas lines are dangerous if ruptured, so professional disconnection is mandatory. Never attempt to disconnect gas service yourself.
Sewer lines typically get capped as part of the demolition process, but coordinate with your contractor about exactly when and how this happens. Seattle Public Utilities has specific requirements for how sewer lines are capped when structures are demolished.
If you have cable, internet, phone lines, or other services connected to the structure, arrange for those to be disconnected too. While they’re not as dangerous as gas or electricity, having them disconnected prevents complications during demolition.
Some homeowners want to keep utilities connected as long as possible if they’re using the structure until right before demolition. That’s understandable, but build in enough time for all disconnections to happen before the scheduled demolition date. Utility companies don’t always show up the day you call them.
Address Hazardous Materials Before Demolition Day
If your property was built before 1985, asbestos testing should have already been completed as part of the permitting process. If asbestos was found, certified abatement contractors must remove it before demolition begins. This isn’t something that happens on demolition day. It’s a separate process that must be completely finished beforehand.
The same goes for lead paint remediation if that’s required for your project. Hazardous material removal happens before the demolition crew arrives, not during demolition.
Underground oil tanks are another issue that needs to be addressed in advance. Many older Seattle homes had heating oil tanks that were either removed years ago or potentially still exist underground. If there’s any possibility of an underground tank on your property, it needs to be located and dealt with before demolition. Rupturing an unknown oil tank during demolition creates an environmental nightmare and massive cleanup costs.
Make sure your demolition contractor has copies of all hazardous material reports and abatement documentation. They need to know what was found and what was removed so they can work safely and comply with regulations.
Notify Your Neighbors
Demolition is disruptive. It’s loud, it’s dusty, and it brings heavy equipment and trucks to your street. Being a good neighbor means giving people advance notice about what’s coming.
Talk to the neighbors on either side of your property and anyone directly across the street or behind you. Let them know when demolition is scheduled to begin, approximately how long it will take, and what they can expect in terms of noise and activity.
Apologize in advance for the inconvenience. Most neighbors are understanding if you’re upfront with them. It’s when demolition starts unexpectedly that people get upset.
Give neighbors your contact information and your demolition contractor’s contact information in case any issues arise. If dust is blowing onto someone’s car or noise is happening outside permitted hours, you want them to be able to reach you to address the problem rather than calling the city to file complaints.
Some cities require you to notify neighbors in writing. Check Seattle’s specific requirements for your area. Even if written notice isn’t required, providing it anyway is a courteous gesture that helps maintain good relationships.
Arrange for Dumpster and Equipment Access
Large roll-off dumpsters will likely be placed on your property or potentially in the street in front of your property. These dumpsters are huge, often 30 or 40 yards, and they’ll sit there for days or even weeks depending on your project timeline.
Make sure there’s clear space for dumpster placement. The area needs to be level, accessible for the truck that delivers the dumpster, and positioned where the demolition crew can easily load debris into it.
If the dumpster needs to be placed in the street, you may need a permit from the Seattle Department of Transportation. Your demolition contractor typically handles this, but verify it’s been taken care of.
Heavy equipment like excavators and loaders need room to operate. They’re not as maneuverable as regular vehicles and require significant space. Make sure your property has adequate access and that there aren’t obstacles like low-hanging wires, narrow gates, or tight turns that could prevent equipment from reaching the demolition site.
Final Preparations the Day Before
The day before demolition is scheduled to begin, do a final check of your property. Walk the perimeter and verify everything’s ready.
Confirm that all utilities are disconnected and you have documentation proving it. Double-check that nothing you want to keep is still inside or around the structure. Verify that the area is clear and accessible for equipment. Make sure your dumpster has been delivered if that was scheduled in advance.
Touch base with your demolition contractor to confirm they’re still on schedule and ask if there’s anything else you need to do before they arrive. Professional contractors will have walked the site beforehand and discussed preparation requirements, but a final confirmation call prevents any last-minute surprises.
If you haven’t already done so, take those final photos documenting the property before demolition begins.
