"How long will this take?" is the second question every homeowner asks, right after the price. It is also the question the industry answers worst, because most of the numbers people quote describe only the part where crews are in the house.
A remodel has three clocks running: design and selections, permit review, and construction. The last one is the shortest on almost every project. Here is what each stage really costs you in calendar time in the Denver metro, and where the schedule usually goes wrong.
The part of the schedule nobody counts
Say a kitchen takes eight weeks of construction. True enough. But before that: two to four weeks to settle the layout, three to six weeks to make selections and get everything ordered, and however long the city takes to review the permit. Cabinets alone commonly run six to ten weeks from order to delivery, and a job that starts before they arrive is a job with a stall built into the middle of it.
Front-loading is what makes a schedule hold. Every decision made before demo is a decision that cannot delay the crew later, which is why we push hard on selections early even though it is the least fun part for most people.
Real timelines by project type
These are the ranges we plan around for Denver-metro projects. They assume decisions get made at a normal pace and the permit path is ordinary — no historic review, no variance, no structural surprise behind the drywall.
| Project | Design & selections | Permit | Construction | Total |
|---|---|---|---|---|
| Bathroom remodel | 2–4 weeks | 1–4 weeks | 3–6 weeks | 2–3 months |
| Kitchen remodel | 3–6 weeks | 2–6 weeks | 6–10 weeks | 3–5 months |
| Basement finish | 3–5 weeks | 3–8 weeks | 8–12 weeks | 4–6 months |
| Deck build | 2–3 weeks | 2–6 weeks | 2–4 weeks | 2–3 months |
| Roof replacement | about 1 week | 0–2 weeks | 1–3 days | 3–6 weeks |
| Exterior / siding | 2–3 weeks | 1–3 weeks | 2–5 weeks | 2–3 months |
| Home addition | 6–12 weeks | 8–16 weeks | 4–7 months | 9–18 months |
| Whole-home renovation | 8–14 weeks | 8–16 weeks | 5–9 months | 12–20 months |
| ADU or new build | 8–16 weeks | 12–24 weeks | 6–10 months | 14–24 months |
Two things stand out on that table. Roof replacements are days of work wrapped in weeks of scheduling. Additions and new builds are permit projects with construction attached — the review is often the single longest phase, and it is the one nobody can speed up by working weekends.

What the permit adds, city by city
Permit review is the least predictable phase because it is not yours to control. It varies by jurisdiction, by season, by how busy the department is that month, and enormously by how complete your submittal was on the first pass.
The single biggest lever you do control is submittal quality. A complete package with drawings that answer the reviewer's questions before they ask goes through once. An incomplete one collects comments, gets resubmitted, and goes back into the queue — and each round trip can cost more than the original review.
Additions and structural work add engineering to the front of that. Historic districts add design review. Anything near a sewer line or in a floodplain adds a separate review. Our permit guide covers what each metro jurisdiction requires and roughly how long it takes — see the process breakdown.
Nobody ever complained about a job finishing when we said it would. Every complaint I have ever gotten about time came from a promise somebody made to win the work.

What actually causes delays
Weather is what people expect. It is rarely the answer. In order of how often they actually cost us days:
- Decisions made late. A tile choice outstanding on the day the tile setter is scheduled does not just cost that day — it costs the next opening in that trade's calendar, which may be two weeks out.
- Long-lead materials ordered late. Cabinets, windows, specialty tile and appliances all have lead times measured in weeks. Ordering after demo guarantees a gap.
- What is behind the wall. Knob-and-tube wiring, cast iron drain lines, a wall that turns out to be bearing, asbestos in old flooring. Older Denver housing stock is full of this, which is why we open a wall early where we can.
- Permit resubmittals. See above.
- Change orders. Every mid-project change costs the change plus the resequencing around it. Some are worth it. All of them cost time.
- Weather. Real, but mostly on exterior work, and mostly manageable.
Five of those six are decided before the first crew arrives. That is the whole argument for spending longer in planning than feels necessary.

What eight weeks of kitchen construction looks like
Ranges are useful for planning and useless for knowing what happens on a Tuesday. This is the sequence on a typical Denver kitchen where the layout changes but the room does not move — the eight-week construction block from the table above.
| Week | On site | What has to be finished already |
|---|---|---|
| 1 | Protection, demo, haul-off; first look behind the walls | Permit issued, cabinets ordered, appliances confirmed |
| 2 | Framing changes, any structural work | Final layout locked — this is the last cheap moment to move a wall |
| 3 | Electrical, plumbing and mechanical rough-in | Lighting plan, outlet locations, sink and range positions |
| 4 | Rough-in inspections, then insulation and drywall | Nothing new — this week is the city's |
| 5 | Tape, texture, prime, paint; flooring if it runs under cabinets | Paint colors, flooring delivered |
| 6 | Cabinet install | Cabinets on site and inspected for damage before install day |
| 7 | Countertop template, fabrication, install; backsplash after | Slab selected; template cannot happen before cabinets are set |
| 8 | Trim, appliances, fixtures, punch list, final inspection | Hardware, faucet, lighting fixtures all on site |
Notice how much of the right-hand column is decisions rather than work. Week seven is the one that surprises people: countertops cannot be templated until the cabinets are physically installed, and fabrication takes one to two weeks after that. There is no way to compress it, so a kitchen has a built-in gap between cabinets and counters that a good schedule fills with other trades instead of pretending it does not exist.
Building through a Colorado winter
Front Range winters are less of an obstacle than people assume. The sun is strong, the dry spells are long, and a lot of what we do is indoors anyway. Kitchens, bathrooms, basements and whole-home interiors run straight through January without much trouble.
Exterior work takes more planning. Concrete needs temperature management to cure properly. Some adhesives, sealants and paints have minimum application temperatures. Roofing shingles need warmth to seal, though on a sunny Colorado afternoon that is often available in ways it would not be elsewhere. Ground that is frozen hard makes excavation slower and more expensive.
The trade-off is real, though: winter is when trade calendars open up. A basement or interior project scheduled for December and January often starts sooner and runs tighter than the same project booked for June, because everyone in the metro wants their deck built in June.
How we keep a schedule honest
Four things, none of them clever:
- Selections finished before demo. Every material chosen, ordered and confirmed with a delivery date before anything comes apart.
- A written schedule with the trades named. Not "four to six weeks" — the actual sequence, with who is on site which week.
- One point of contact. Delays multiply when a homeowner is coordinating six subcontractors who each believe someone else was going first.
- Contingency stated out loud. On a 1970s house we plan for surprises rather than pretending there will not be any. That way a surprise costs its own time and not the whole schedule's credibility.
If you want a date you can plan a life around, start with a scope and a real number. Our instant calculators give you the budget side, the pricing guide explains what moves it, and a free walkthrough gets you the schedule alongside the estimate.
We build across Denver, Greenwood Village, Centennial, Littleton, Aurora, Lakewood and the rest of the metro — whole-home renovations, additions, kitchens, baths and basements. Call (720) 980-3913 or book a walkthrough and we will give you a timeline we intend to keep.
