A homeowner in Nowra recently asked for a quote after spending three weekends trying to paint their weatherboard exterior alone — and barely finishing one wall. It’s a familiar story across the Shoalhaven region.
A professional painter can paint a standard 3-4 bedroom house in 3 to 7 days. A DIY painter working solo on the same home can take 2 to 4 weeks or longer, depending on preparation, skill level, house size, and weather conditions in your area.
The gap between those two timelines comes down to preparation, equipment, crew size, and experience. Whether you are planning an interior refresh in Berry or a full exterior repaint in Bomaderry, getting a realistic timeline upfront saves you from disruption, cost blowouts, and half-finished results.
This article covers:
- Painting timelines broken down by house size
- A direct comparison of professional vs DIY painting durations
- Interior and exterior time estimates for NSW homes
- Preparation stages and how long each one takes
- Local Shoalhaven climate factors that affect drying and scheduling
Professional vs DIY House Painting Timelines
A licensed painting crew with the right equipment moves at a pace that a solo DIY painter simply cannot match. Two to three professionals working together complete tasks in parallel, maintain a clean worksite, and move from preparation through to final coat without the delays that accumulate across weekends.
For a 150m² home, a two-person professional team can complete an interior repaint in 3 to 4 days. The same project done solo by a homeowner on weekends typically stretches to 3 to 4 weeks, sometimes longer when you account for drying time between coats and preparation that gets skipped or rushed.
The table below compares professional and DIY timelines across common house sizes in the Berry and Shoalhaven region.
| House Size | Professional Crew (2-3 painters) | DIY (Solo) |
|---|---|---|
| 100m² | 2 to 3 days | 1 to 2 weeks |
| 150m² | 3 to 4 days | 2 to 3 weeks |
| 200m² | 4 to 5 days | 3 to 4 weeks |
| 250m² | 5 to 7 days | 4 to 5 weeks |
| 300m² | 6 to 8 days | 5 to 6 weeks |
Professional painting timelines assume proper surface preparation, two coats of paint, and appropriate drying time between each coat. DIY timelines reflect realistic weekend-only schedules with basic tools and no prior professional training.
One pattern that stands out after 11+ years of painting across NSW: homes where the owner attempted DIY preparation before calling in a professional often take longer to finish, not shorter. Sanding that misses the bond coat, filler applied over damp substrate, or primer skipped entirely all require correction before a quality topcoat can go on.
NSW painting standards expect proper surface preparation before any topcoat application. Skipping that step shortens the life of the paint job regardless of the paint brand used.
How House Size Impacts Painting Duration
House size is the single biggest driver of painting duration, but it is not the only one. Storey count matters as much as floor area. A double-storey home of 200m² takes longer than a single-storey home of the same size because scaffolding or ladder repositioning adds time, and access to eaves, soffits, and upper exterior walls requires more care.
The table below gives average painting time estimates for different house sizes based on a two-to-three person professional crew completing a full interior and exterior repaint.
| House Size | Storeys | Crew Size | Est. Days (Interior Only) | Est. Days (Exterior Only) | Est. Days (Full House) |
|---|---|---|---|---|---|
| 100m² | Single | 2 | 2 days | 2 to 3 days | 3 to 4 days |
| 150m² | Single | 2 | 2 to 3 days | 3 days | 4 to 5 days |
| 200m² | Single | 2 to 3 | 3 to 4 days | 3 to 4 days | 5 to 6 days |
| 200m² | Double | 2 to 3 | 3 to 4 days | 4 to 5 days | 6 to 7 days |
| 250m² | Double | 3 | 4 to 5 days | 4 to 5 days | 7 to 8 days |
| 300m² | Double | 3 | 5 to 6 days | 5 to 6 days | 8 to 10 days |
These estimates cover walls, ceilings, trims, doors, and all standard surfaces. Roof painting, deck painting, and fence painting each add time on top of a standard exterior quote.
A 3 to 4 bedroom house in Nowra or Berry typically sits in the 150 to 220m² range. Based on the estimates above, a full repaint by a professional crew runs 5 to 7 days for most homes in that bracket.
Interior vs Exterior Painting Time Estimates
Interior and exterior painting involve different surfaces, different preparation demands, and different drying conditions, so their timelines run separately even when both are part of the same project.
Interior painting covers walls, ceilings, trims, doors, skirtings, and in some cases feature walls or cabinetry. A standard 3-bedroom interior repaint with two coats on walls and ceilings takes 2 to 4 days for a professional crew. Rooms are painted sequentially to allow adequate drying time between coats, and furniture protection, masking, and cleaning add time that DIY estimates often ignore.
Exterior painting takes longer on a per-surface basis because access, weather windows, and surface preparation are more demanding. Washing, sanding, filling cracks, applying primer to bare timber or masonry, and then applying two topcoats across walls, eaves, fascias, trims, and window frames adds up. A standard single-storey exterior repaint takes 2 to 4 days professionally. A double-storey exterior runs 4 to 6 days with scaffolding or elevated access equipment factored in.
The Shoalhaven coast brings specific challenges for exterior painting. Salt air near Culburra Beach and Shoalhaven Heads accelerates paint breakdown and means exterior surfaces need more thorough preparation than inland properties. Drying windows matter too: humidity above 85% slows latex paint cure times, and painting in direct afternoon sun on western-facing walls in summer causes the paint to skin before it bonds properly.
A combined interior and exterior project on a 4-bedroom Berry NSW home with a professional crew would realistically run 6 to 8 working days in mild weather conditions.
Key Factors That Affect How Long Painting Takes
No two painting projects run to exactly the same schedule. Surface condition alone can add days to a job that looked simple from the street.
Surface condition is the most unpredictable factor. Old weatherboard homes common throughout the Shoalhaven region often have multiple layers of old paint, bare timber patches, rotted sections, and rusted fixings beneath the surface. Stripping, filling, sanding, and priming these areas before applying a topcoat adds half a day to a full extra day depending on severity.
The number of coats required directly affects the timeline. A standard repaint needs two topcoats. Going from a dark colour to a light one often needs a third coat or a dedicated tinting primer to block the old colour from showing through. Each coat needs adequate drying time before the next one goes on, which a professional schedules around weather and product specifications.
Weather is a scheduling factor that many homeowners underestimate. Exterior painting stops on rainy days. Temperatures below 10°C or above 35°C push paint outside its application window. The Shoalhaven region in August 2026 sees cooler mornings, meaning crews often start exterior work later in the morning to allow temperature and dew point conditions to reach the right range for adhesion.
The number of rooms, the ceiling height, and the presence of architectural detail like cornices, arched windows, or decorative trims all extend the timeline. Open-plan living spaces with high ceilings take longer per square metre than standard-height rooms with simple rectangular surfaces.
Preparation Stages and Time Required
Preparation is the stage that determines how long the paint job lasts. A professional painter invests more time in preparation than in the actual painting, and that ratio shows in the final result.
A standard preparation process for a residential painting project follows this sequence:
Day 1: Washing and inspection. Exterior surfaces need high-pressure washing to remove dirt, mould, chalking, and salt residue. Interior surfaces get wiped down and checked for mould, water stains, and loose paint. This stage takes half a day to a full day depending on house size and condition.
Day 1 to 2: Repair and filling. Cracks, holes, dents, and damaged render get filled, sanded flush, and re-checked. Timber surfaces with rot get cut out and replaced or treated before any paint goes on. Skipping this step means cracks and imperfections telegraph through the topcoat within months.
Day 2: Priming. Bare timber, repaired masonry, stain-prone surfaces, and areas of colour change all receive a primer coat appropriate to the substrate. Primer coat application and cure time can take half a day, with an overnight or minimum 4-hour window before topcoating.
Day 3 onwards: Topcoats. First and second topcoats go on with the manufacturer’s recommended recoat time between applications. Water-based products in warm conditions may recoat within 2 to 4 hours. Cooler or humid conditions in the Shoalhaven region can extend that window to 6 hours or longer.
Homes across Berry, Nowra, and surrounding areas that come in for a quote after years of deferred maintenance regularly need two to three days of preparation before the first topcoat touches the wall. That time is not wasted, it is what separates a paint job that lasts two years from one that lasts ten.

Frequently Asked Questions
How long does it take to paint a 3-4-bedroom house?
A 3 to 4 bedroom house with a professional crew of two to three painters takes 4 to 7 days for a full interior and exterior repaint. The exact duration depends on house size, surface condition, number of coats required, and weather. A 3-bedroom single-storey home runs closer to 4 to 5 days, while a larger double-storey 4-bedroom home may take 6 to 7 days.
How long does it take to paint a house professionally?
A professional painting crew completes most standard houses in 3 to 7 working days. Smaller homes of around 100 to 150m² take 3 to 4 days with two painters. Larger homes of 250 to 300m² take 7 to 10 days with a crew of three. These timelines include preparation, priming, and two topcoats, with proper drying time scheduled between each stage.
What factors affect how long it takes to paint a house?
The main factors are house size, surface condition, number of coats, crew size, and weather conditions. Homes with peeling paint, cracks, mould, or bare timber need more preparation time before topcoats begin. Exterior projects in coastal areas like the Shoalhaven require more thorough preparation due to salt air exposure and humidity affecting adhesion and drying times.
How long does it take to paint the interior of a house?
A professional crew paints a standard 3-bedroom interior in 2 to 4 days, covering walls, ceilings, doors, and trims with two coats. Larger homes or those with high ceilings, detailed cornices, or multiple feature walls take longer. A solo DIY painter on weekends can expect the same interior to take 2 to 4 weeks, accounting for drying time and setup between sessions.
How long does it take to paint a house exterior in NSW?
A single-storey exterior in NSW takes 2 to 4 days professionally, including washing, preparation, and two topcoats. A double-storey exterior adds a day or two for scaffolding and access. In the Shoalhaven region, coastal humidity and salt air mean preparation takes longer than average, and weather windows in winter months require scheduling around cooler mornings and afternoon temperature drops.
