What to Expect During a Whole-Home Renovation

A whole-home renovation is one of the most rewarding things you can do for your home — and one of the most disruptive things you can do to your daily life. Understanding what the process actually looks like, start to finish, makes it significantly easier to manage the stress, the decisions, and the temporary chaos that comes with living through a major construction project.

Here is what to expect if you are planning a whole-home renovation in Metro Detroit.

Phase 1: Planning and Design (2 to 6 Weeks)

Before a single hammer swings, there is a planning phase that determines the success or failure of everything that follows. This phase includes an initial walkthrough with your contractor to discuss goals, priorities, and budget. You will work through the scope of work — what stays, what goes, what changes. If structural modifications are involved, you may need architectural drawings or engineering calculations.

This is also when you start making material selections. Cabinets, countertops, flooring, tile, fixtures, appliances, paint colors — these all need to be decided and ordered before construction begins, not during. Lead times on materials are real. Custom cabinets can take six to eight weeks from order to delivery. Special-order tile may take three to four weeks. If you wait until the project is underway to make these decisions, you will create delays and idle time where your contractor is waiting on materials instead of working.

A good contractor will help you sequence these decisions and track lead times so everything arrives when it is needed. At Pro-Time Services, we provide a material selection schedule that shows what needs to be ordered and when, so nothing falls through the cracks.

Phase 2: Permits and Preparation (1 to 3 Weeks)

Most whole-home renovations in Metro Detroit require building permits, especially if you are doing any structural, electrical, plumbing, or HVAC work. Your contractor should handle the permit application, plan submission, and fee payment. Permit turnaround in most Southeast Michigan communities is one to two weeks for residential renovation projects.

During this waiting period, you should be preparing your home. Move furniture and personal items out of the work areas. If the renovation is extensive enough that you will need to move out temporarily, arrange housing now. Pack up valuables and fragile items. Identify what you will need access to during construction — medications, important documents, daily essentials — and keep them somewhere accessible.

Phase 3: Demolition (1 to 2 Weeks)

This is the loud, dusty, dramatic phase that makes every renovation feel like it was a terrible idea. Old cabinets come out, walls come down, flooring comes up, old plumbing and electrical get ripped out. It looks worse before it looks better — significantly worse.

Demolition is also when surprises happen. The wall you wanted to remove turns out to be load-bearing. The plumbing behind the bathroom wall is corroded galvanized steel that needs replacement. There is water damage behind the kitchen cabinets that nobody could see. Knob-and-tube wiring in the attic. Asbestos in the floor tile.

These discoveries are not the contractor's fault and they are not unusual in Metro Detroit homes built before 1980. A good contractor will communicate these findings immediately, explain the options, provide the cost to address them, and let you decide how to proceed. This is why experienced contractors build contingency into their estimates — typically 10 to 15 percent of the total budget for unforeseen conditions.

Phase 4: Rough-In (2 to 4 Weeks)

After demolition, the house looks stripped and skeletal. Now the trades come in to install the infrastructure that will be hidden behind walls and floors for the next 30 years. Electricians run new circuits, add outlets, and install boxes for switches and fixtures. Plumbers run new supply and drain lines. HVAC technicians install or modify ductwork. If you are making structural changes, the framing crew installs beams, headers, and new wall framing.

This phase does not look visually impressive — you are staring at open stud walls with wires, pipes, and ducts running through them — but it is arguably the most important phase of the project. Everything that happens after this point depends on the rough-in being done correctly. This is also when the building inspector comes for the rough-in inspection, verifying that all the work behind the walls meets code before it gets covered up.

Phase 5: Insulation, Drywall, and Closing Up (1 to 3 Weeks)

Once the rough-in passes inspection, insulation goes in, then drywall. Drywall is hung, taped, mudded, and sanded — typically requiring three coats of joint compound with sanding between each coat. This is a dusty process, and drywall dust gets everywhere despite best efforts with barriers and protection.

After drywall, the house starts looking like a house again. Walls are smooth, rooms have their final shapes, and you can begin to visualize the finished result. Priming and first-coat painting typically happen at this stage as well.

Phase 6: Finish Work (3 to 6 Weeks)

This is the longest phase and the most detail-intensive. Finish work includes cabinet installation, countertop templating and installation (there is usually a one to two week gap between templating and install), tile work in kitchens and bathrooms, hardwood or LVP flooring installation, trim work — baseboards, crown molding, door casings, window trim, interior door hanging, hardware installation (knobs, pulls, hinges, towel bars, toilet paper holders), fixture installation (lights, fans, outlets, switches), plumbing fixture installation (sinks, faucets, toilets, shower fixtures), appliance installation, and final painting and touch-up.

Finish work requires patience. Each trade needs the previous one to be complete before they can start. The flooring goes in after cabinets but before trim. Countertops go in after cabinets but before the plumber connects the sink. The final paint touch-up happens after everything else is installed. Sequencing mistakes in this phase create delays and rework.

Phase 7: Punch List and Final Inspection (1 Week)

After all the work is complete, you and your contractor walk the entire project together, room by room, creating a punch list — a list of items that need correction, adjustment, or touch-up. Maybe a door does not close properly. A paint drip on a window sill. A cabinet door that is slightly out of alignment. A outlet cover that is crooked. These are normal, expected items that get addressed in the final week.

Once the punch list is complete, the building inspector comes for the final inspection. If everything passes, the permit is closed and the project is officially done.

Realistic Timeline for a Whole-Home Renovation

A comprehensive whole-home renovation in Metro Detroit typically takes 12 to 20 weeks from demolition to completion, depending on the scope. Add 4 to 6 weeks of planning and permitting on the front end, and you are looking at roughly 4 to 6 months total from initial consultation to move-in. Projects involving structural changes, additions, or extensive custom work can run longer.

Anyone who tells you a whole-home renovation can be done in four weeks is either not planning to pull permits, not doing the work correctly, or not giving you an honest timeline. Quality work takes time. Rushing creates problems that are expensive to fix later.
