Renovation Project Timelines: How Long Does Each Project Take?

Why Timelines Matter

Underestimating project duration is one of the most common renovation mistakes. It leads to rushed work, unexpected accommodation costs, and the stress of living in a construction zone longer than planned. This guide gives you realistic timeframes for the most common home renovation projects.

Project Timeline Overview

Project	DIY Time	Professional Time	Key Variable
Paint a room (walls only)	1–2 days	0.5–1 day	Prep condition, number of coats
Paint full house interior	7–14 days	3–5 days	Number of rooms, ceilings included
Tile a bathroom (walls + floor)	4–7 days	2–3 days	Tile size, cuts required, drying time
Tile a kitchen backsplash	1–2 days	0.5–1 day	Pattern complexity
Lay laminate flooring (room)	1–2 days	0.5–1 day	Subfloor prep, room shape
Lay flooring (full house)	5–10 days	2–4 days	Transitions, stairs, obstacles
Bathroom renovation (full)	14–28 days	7–14 days	Scope: cosmetic vs full refit
Kitchen renovation (full)	21–42 days	10–21 days	Custom vs flat-pack cabinets
Loft insulation	1–2 days	0.5–1 day	Access, loft size
Wall insulation (internal)	5–10 days	3–5 days	Room size, replastering needed
Fence replacement (15 m)	2–3 days	1–1.5 days	Ground conditions, post depth
Decking (15 sqm)	3–5 days	1.5–2.5 days	Subframe complexity, steps
Roofing (full re-roof)	—	5–10 days	Roof size, stripping old covering
Drywall a room	3–5 days	1–2 days	Taping and sanding time
Exterior painting (house)	7–14 days	3–7 days	Weather windows, scaffold setup

All times assume standard-sized residential projects. Times include drying and curing periods where applicable.

Factors That Affect Every Timeline

Preparation condition. A room with perfect walls takes half the prep time of one with cracks, damp, or old wallpaper to strip. Budget extra days if the space needs significant preparation.

Drying and curing times. Paint needs 2–4 hours between coats. Tile adhesive needs 24 hours before grouting. Concrete needs 48 hours before loading. These mandatory waits cannot be skipped without compromising the result.

Weather (exterior projects). Exterior painting, roofing, fencing, and decking all depend on dry conditions. Rain and temperatures below 5 degrees Celsius halt most exterior work. Build weather contingency into your schedule.

Material delivery delays. Special-order tiles, custom worktops, and made-to-measure windows can add 2–6 weeks of lead time. Order these first and schedule the work around their delivery date.

Scope creep. Once you open a wall or lift old flooring, you may discover problems: damp, rotten timber, outdated wiring, or asbestos. Allow a contingency buffer of 20–30% on your timeline for unexpected discoveries.

How to Build a Realistic Schedule

1. Work backwards from your deadline. If you need the bathroom finished for a specific date, count backwards and add 30% buffer.
2. Sequence trades correctly. Plumber and electrician first (first fix), then plasterer, then tiler, then second fix plumbing and electrics, then painter. Getting this order wrong causes delays and rework.
3. Do not overlap trades. Two trades working in the same small room slow each other down. Stagger them so each has clear access.
4. Use our calculators to order materials early. Running out of tiles on day three means a stop while you source more from the same batch. Use the tile calculator or flooring calculator to order the right quantity from day one.
