A whole house renovation usually takes about 4 to 12 months or more, from the first design meeting to move-in. That is the range in our 19-step renovation process guide, and it holds for the Massachusetts and New Hampshire homes we work on. The spread comes from the size of the house, how much structure changes, how long selections and permits take, and what turns up behind the walls.
Norman Builders is a design-build home builder and remodeler at 63 Peaslee Crossing in Newton, NH. We have done whole house renovations in northern Massachusetts and southern New Hampshire since 2007. This guide breaks the timeline into phases so you can plan around it. Costs and budgeting are covered in our whole house renovation budget guide, and the full step-by-step list is in our 19-step renovation process and timeline.
The Complete Timeline for a Whole House Renovation
Typical Timeline
Think of a whole house renovation in two parts: a planning phase and a construction phase. Both are long, and the planning phase often runs as long as the building. The durations below come from our 19-step guide.
| Phase | Typical duration |
|---|---|
| Define vision and scope | 1 to 2 weeks |
| Set the budget and secure financing | 1 to 2 weeks |
| Hire the team | 1 to 2 weeks |
| Design and blueprints | 2 to 6 weeks |
| Finalize selections and order materials | 1 to 3 months |
| Permits and approvals | 2 weeks to 3 months |
| Site prep and demolition | About 1 week each |
| Structural work and framing | 1 to 8 weeks |
| Plumbing, electrical and HVAC rough-in | 1 to 3 weeks |
| Insulation and drywall | 1 to 4 weeks |
| Windows, doors and flooring | 1 to 2 weeks |
| Interior finishes and painting | 1 to 2 weeks |
| Cabinetry and countertops | 2 to 4 weeks |
| Fixtures | 1 to 2 weeks |
| Final flooring and backsplash, appliances, final inspections and punch list, cleaning | About 1 week each |
The guide groups pre-construction at 4 to 12+ weeks and construction at 2 to 12+ months. Many of these steps overlap, so the totals are not simple sums. Treat the table as a guide, not a promise: your schedule depends on your house.
Full Gut Remodel
Stripping a house to the studs adds structural, mechanical and insulation work, so it sits at the long end. See our gut renovation guide for when it makes sense and how it is priced.
From Our Projects
We do not publish a duration for every case study, so these come from homeowners' own reviews and the project pages.
- Newburyport, MA, 120-year-old house: the homeowner wrote that "work never stopped from October 1st thru the end of the job six months later," including the last two and a half months of snow.
- Andover, MA, large structural remodel: the homeowners moved out for 4 months, and wrote: "The project was finished ahead of schedule, on budget."
- Andover, MA: another client wrote that "Norman Builders began our project at the end of June 2014 and completed the work at the beginning of November 2014."
- Hampton, NH beach cottage addition and renovation: the homeowners planned an October 2010 start with a February 2011 finish and wrote that the project "was finished on time."
- Whole-home renovation, Andover, MA (2026, 2,900 sq ft, $1,000,000 budget band): we did not record this project's schedule, so we point to our guide's range of 4 to 12 months or more.

Factors Influencing Renovation Timelines
Project Scope
One room takes weeks. Opening walls, moving a kitchen or changing the structure takes months. Our guide puts a kitchen remodel at 6 to 16 weeks and a bathroom remodel at 3 to 10 weeks (3 to 5 weeks for a basic one, 6 to 10 weeks for a full gut with layout changes). A home addition runs 3 to 9 months. For an addition alone, see our home additions page.
Home Size
More rooms, more bathrooms and more specialty spaces mean more planning, more trades and more material to order.
Weather
Winter slows exterior work and site access in New England. If your schedule crosses a winter, plan for it. The Newburyport job above worked through snow, and our whole-home renovation in Massachusetts guide covers winter scheduling.
Permits and Approvals
Permit review, inspections and, in some towns, historic or other local approvals take time. Our guide allows 2 weeks to 3 months.
Unforeseen Issues
Older houses hide problems such as water damage, outdated wiring or structural surprises, and they show up after demolition. Keep a contingency in both the budget and the schedule. Our guide suggests a contingency of 15 to 20 percent for the budget, especially for older homes.
Tips for Staying on Schedule
- Choose your contractor early. A design-build firm keeps design and construction together, which speeds decisions. Our whole house renovation companies guide shows how to compare firms.
- Finish interior design before demolition. Lock in cabinets, tile, appliances and fixtures early so no order holds up the job.
- Know the lead times. Custom cabinets and specialty tile can take weeks to several months to arrive.
- Decide quickly during construction. Change orders ripple through the schedule.
- Plan where you will live. Some homeowners move out for part of the job, as the Andover family above did for 4 months.

Frequently Asked Questions
Is $100,000 enough to renovate a house?
It depends on the scope, and for a whole house it is usually tight. The five whole-home and main-floor renovations in our case studies carry budget bands from $200,000 to $1,000,000, so $100,000 tends to go further on a few rooms than on an entire house. Our whole house renovation budget guide shows how to set and phase a budget.
Why does it take so long to renovate a house?
Because most of the time is spent before and around the building. Design, selections, material lead times and permits come first, and construction runs in a set order: demolition, framing, rough-in work, insulation and drywall, then finishes. Older houses add surprises once the walls are open.
How many days does it take to renovate a house?
A whole house renovation is counted in months, not days. Our renovation process guide puts a whole-home renovation at about 4 to 12 months or more from design to move-in. Individual steps, such as demolition or appliance installation, take about a week each.
