What to do before contractors arrive
Before renovation work starts, you need to clear the work area, protect what stays, document existing conditions, and establish how the contractor will access your home and manage debris. This takes one to three weeks depending on the size of the project. The goal is to prevent damage to belongings, reduce safety hazards, and create a clear boundary between the work zone and the rest of your home.
Start by removing everything from the rooms being renovated — furniture, décor, personal items, and anything stored in closets or cabinets. If the work involves walls, ceilings, or flooring, assume dust will travel. Move items from adjacent rooms too, or seal doorways with plastic sheeting and duct tape. Take photos of the current state of the space before work begins; these become evidence if a contractor damages something that was already there.
Identify utilities that run through the work area — electrical outlets, light switches, water pipes, gas lines, HVAC ducts. Tell your contractor which ones must stay live during work and which can be shut off. If you are unsure where utilities are located, contact your local utility locating service (usually free) before digging or cutting into walls. Some contractors will do this themselves, but confirming it in writing protects you.
Key Takeaways
- Remove all personal items and furniture from the renovation area at least one week before work begins, and photograph the space to document its condition.
- Locate and mark all utilities — electrical, plumbing, gas, HVAC — and confirm with your contractor which ones will be affected and how they will be protected.
- Seal off the work area from the rest of your home using plastic sheeting and duct tape to contain dust and debris, and establish a single entry point for contractors.
- Arrange temporary access for contractors, confirm where they will park and store materials, and agree on daily work hours and debris removal schedule in writing.
- Notify your insurance company and mortgage lender that renovation work is happening, and verify that your homeowner's policy covers contractor liability.
Protecting the rest of your home from dust and damage
Renovation dust travels through air ducts, under doors, and through open doorways into every room. The standard method is to seal the work zone completely using plastic sheeting, duct tape, and a temporary barrier at the entry point. This is not optional for kitchen or bathroom work, and strongly recommended for any project involving demolition, sanding, or cutting.
Tape plastic sheeting over doorways, vents, and return-air grilles in the work area. Use heavy-duty duct tape and overlap seams by at least six inches. If the work involves the HVAC system itself, ask your contractor whether the system should be shut down during demolition to prevent dust from circulating through the whole house. For projects lasting more than a few days, consider renting a negative-pressure containment system — a portable unit that exhausts dust outside rather than letting it settle indoors.
Cover or remove light fixtures, ceiling fans, and smoke detectors in the work area. Tape over any remaining vents or openings. If flooring is being removed or replaced, lay down plywood or cardboard on adjacent floors to protect them from foot traffic and dropped tools. Contractors should provide their own floor protection, but confirming this in your contract prevents disputes later.
Setting up access and establishing work boundaries
Decide where contractors will enter and exit, where they will store materials, and where they will stage debris. This should be one consistent route, not multiple entry points that track dirt through your home. If possible, use an exterior entrance closest to the work area. If that is not available, designate one interior door and lay down protective flooring from that door to the work zone.
Confirm with your contractor where they will park their vehicles and whether they need space for a dumpster or debris bin. Some neighborhoods have restrictions on street parking or dumpster placement; check your local rules and your homeowner's association rules if you have one. Agree on the schedule for debris removal — daily, weekly, or at project end — and put this in the contract.
Establish clear work hours. Most contractors work 7 a.m. to 4 p.m. on weekdays, but confirm this before they start. If you have neighbors close by, let them know the project timeline. Agree on what happens if work extends beyond the estimated end date, and whether the contractor will be on-site on weekends or evenings.
Documenting conditions and taking photos
Photograph every wall, ceiling, floor, and fixture in the work area before the first day of work. Take wide shots and close-ups of any existing damage, stains, cracks, or wear. These photos protect you if a contractor claims damage was pre-existing, or if you need to dispute a claim that they caused damage they did not.
Walk through the space with your contractor before work begins and point out anything fragile, valuable, or off-limits. Ask them to initial or sign a document listing these items. If there are antique fixtures, original hardwood under carpet, or anything you want preserved, make this explicit in writing.
Create a straightforward written record of the project scope — what is being removed, what is being added, what is staying as-is. This becomes a reference if questions arise about what was supposed to happen. Include the contractor's name, license number, insurance information, and the start and end dates.
Arranging utilities and temporary services
Confirm with your contractor how they will use water and electricity during the project. Most contractors need access to an outdoor outlet or a hose bib. If they will be using your water heavily (for dust control or cleanup), your water bill may increase; factor this into your budget. If they need to run power tools, confirm they have their own generator or will use your outlets, and whether they will need additional circuits installed temporarily.
If the work involves shutting off water or electricity to part of your home, arrange this for a time when you can be present. Know how to restore service if something goes wrong. If the contractor will be cutting into walls or ceilings, confirm they have located all utilities first — this is a legal requirement in most places and a safety issue.
If the project will last more than a few days and you will be without a kitchen or bathroom, arrange alternative facilities. Some people stay with family; others rent a portable toilet or arrange to use a neighbor's facilities. Plan this before work starts so you are not scrambling mid-project.
Reviewing your insurance and contract protections
Contact your homeowner's insurance company and tell them about the renovation. Ask whether your policy covers contractor liability and what happens if a contractor damages your home or injures themselves on your property. Some policies require you to notify them before work begins; failing to do so can void coverage.
If you have a mortgage, your lender may also require notice of major work. Check your loan documents or call your lender to confirm. This is usually a formality, but skipping it can create problems if something goes wrong.
Review your contract with the contractor carefully. It should specify what is included, what is not, the timeline, the payment schedule, and what happens if work is delayed or incomplete. Confirm that the contractor carries liability insurance and workers' compensation insurance, and ask for proof. If they do not, you may be liable if someone is injured on your property.
Creating a temporary living plan
Depending on the scope of work, you may need to plan how you will live in your home during renovation. If a kitchen is being gutted, you will need a temporary cooking setup — a hot plate, microwave, or eating out. If a bathroom is being renovated, you may need to use a neighbor's or a portable facility. If the work is in a bedroom, you may need to sleep elsewhere.
Plan for noise, dust, and disruption. Contractors typically work during business hours, but some projects require early starts or evening work. If you work from home, discuss this with your contractor and agree on quiet hours if possible. If you have young children or pets, plan how to keep them safe and out of the work area.
Stock up on cleaning supplies before work begins. Renovation creates mess; having vacuum, damp cloths, and trash bags on hand makes daily cleanup easier. Plan to clean the work area at the end of each day if possible, or at least seal it off so dust does not spread overnight.
Frequently Asked Questions
How far in advance should I start preparing?
Start three to four weeks before the contractor arrives if you need to clear a lot of items or arrange temporary living space. If the project is small and you have few belongings to move, two weeks is usually enough. Confirm the start date in writing with your contractor at least two weeks ahead.
What if I find something unexpected during prep, like asbestos or mold?
Stop work when ready and contact a professional inspector. Do not disturb the material. Tell your contractor and your insurance company. Asbestos and mold removal require licensed specialists and may delay the project, but attempting to remove them yourself or letting an unlicensed contractor do it creates serious health and legal risks.
Can I stay in my home during a major renovation?
Yes, but plan for disruption. If the work is in one room, you can usually stay in the rest of the house. If it involves the kitchen or main bathroom, living conditions become difficult. Many people stay elsewhere during the heaviest demolition phase and return once dust containment is in place.
Who is responsible if a contractor damages something in my home?
The contractor is responsible if they caused the damage through negligence or failure to protect your property. This is why documenting pre-existing conditions with photos is important, and why their liability insurance matters. Your homeowner's insurance may also cover some contractor-caused damage, depending on your policy.
What should I do if the contractor is behind schedule?
Refer to your contract, which should specify the timeline and what happens if work extends beyond it. Some contracts include daily penalties for delays; others allow extensions for weather or unforeseen conditions. Communicate early if delays are likely, and get any changes in writing.
