"How long will this take?" It's usually the second question I hear, right after "how much will this cost?" And like the cost question, the honest answer is: it depends. But I can give you realistic ranges and explain what actually drives the timeline.
The Two Timelines Nobody Mentions
When most people think about renovation timelines, they picture construction — the demolition, the framing, the installation. But that's only half the story. Before a single hammer swings, there's a planning phase that takes just as long and matters just as much.
Preconstruction: 12 to 16 weeks. This is our Building the Blueprint process — site evaluation, design development, material selections, subcontractor bidding, detailed estimating, and contract preparation. Twelve to sixteen weeks of structured planning that prevents the chaos that comes from starting before you're ready.
Construction: 3 to 5 months for a kitchen. Once the blueprint is complete and the contract is signed, kitchen construction typically runs 12 to 20 weeks depending on complexity. A straightforward layout swap with stock cabinetry is on the shorter end. A full gut renovation with custom cabinets, structural changes, and relocated plumbing is on the longer end.
Total timeline from first meeting to move-in: 7 to 9 months for most kitchen renovations. Whole-house renovations run 5 to 8 months of construction plus preconstruction, putting the total at 9 to 14 months.
What Extends the Timeline
Selection delays. This is the number one cause of construction delays in my experience, and it's completely preventable. A major kitchen renovation involves over 200 individual material decisions — cabinetry, countertops, tile, flooring, lighting, hardware, fixtures, paint, and more. If those decisions aren't finished before construction starts, the project stops while you decide. Custom cabinets alone take 8 to 14 weeks from order to delivery. If you haven't ordered them by the time framing is done, your project sits idle waiting for cabinets.
Structural surprises. When you open walls in a 1920s Roland Park Colonial, you sometimes find things that weren't in the plans — inadequate framing, outdated plumbing, knob-and-tube wiring, water damage, or structural modifications made by previous owners without engineering. Good preconstruction minimizes this risk through thorough evaluation, but some surprises only reveal themselves during demolition. We budget time and money for the unexpected.
Historic district approvals. If your home is in a CHAP-designated historic district, the approval process adds time. Applications must be submitted and approved before work begins, and the review process can take several weeks depending on the scope and the district advisory committee's meeting schedule. We factor this into the timeline from the start.
Custom millwork and long-lead items. Custom cabinetry, specialty tile, imported fixtures, and handmade hardware all have lead times. Some items take 12 to 16 weeks. We identify these during preconstruction and order them early so they arrive on schedule — but only after selections are finalized.
What Keeps the Timeline on Track
The single most important thing you can do to keep your renovation on schedule is finish your selections before construction starts. Every decision made during preconstruction is a decision that won't cause a delay during construction. That's the entire philosophy behind Building the Blueprint.
Beyond that: trust your construction manager's schedule, respond to questions promptly when they come up, and resist the temptation to make changes mid-stream. Every change during construction — even a seemingly simple one — ripples through the schedule.
The best-run projects are the ones where the hardest decisions were made before the first nail was driven.
Realistic Timelines by Project Type
Kitchen renovation: 12–16 weeks preconstruction + 3–5 months construction. Total: 7–9 months.
Bathroom renovation: 8–12 weeks preconstruction + 6–12 weeks construction. Total: 4–6 months.
Whole-house renovation: 14–18 weeks preconstruction + 5–8 months construction. Total: 9–14 months.
Addition or new construction: 16–20 weeks preconstruction + 6–12 months construction. Total: 10–17 months.
These are realistic ranges for the kind of premium work we do. Can a contractor promise faster? Sure. But speed and quality rarely share the same project.
