House & Commercial Painting FAQs


To help you become a better-informed buyer, here are the answers to the most frequently asking questions about house and commercial painting.


How much does it cost to paint a house?

There are many variables so there is no easy answer.

The variables that impact the cost include:

  1. Size of the house, number of storeys etc
  2. Height of ceilings (will we need scaffolding or a cherry picker)
  3. New build or previously painted
  4. Amount of woodwork – number of doors, size and number of skirting boards / architraves
  5. Staircases
  6. Condition of existing paintwork
  7. Interior of exterior

How are our quotations calculated?

The quotation for painting your house or business is calculated using the above variables.

It will describe what preparation will take place, what priming is necessary, what paints and materials we will use and how many coats we will apply.


Why is there a difference in painting quote prices?

A slight variance of 5%-7% between painting quotes is normal.

Quotes that are very low usually represent the standard of workmanship and products used.

Quotes that are much higher do not necessarily mean that you should expect a better job.  It typically means the painter does not really want the job but will quote anyway just in case the customer is foolish enough to pay over the odds.


When do I book my paint job?

Once you choose your painter, it’s best to book them straight away so you can choose times that are convenient to you. Professional painting businesses are always taking new bookings and can often be booked 3-4 months in advance.

How long will it take to paint my house, apartment, office, etc?

It depends on the size and current condition of your home / premises. Obviously the bigger the house is the longer it will take to paint. The number of walls, number and type of windows, number of frames and doors, height of ceilings and number of painters will affect the number of days it will take to complete the job.

Also, if the surfaces are in poor condition, then a lot of time is required to get them ready for painting. If woodwork is stained, a coat of primer is essential prior to painting. All of these situations affect the time it takes to paint a house.

An average sized, 3-bedroom, single storey house in relatively good condition will take 5 – 7 days to be painted internally. Exterior painting depends on all the above as well as whether it’s clad in weatherboards, stucco, rendered etc.


How do I prepare my home for painting?

Clearing the area as much as possible means the painters don’t have to spend valuable time moving things around. However, we understand that moving furniture is physically demanding, especially if you need help, so we ask our clients to move what they can and leave the heavy items for us. We usually move everything to the middle of the room and cover the whole thing with plastic sheets.

We will paint all ceilings first and then move on to woodwork and walls. If you’d like to have all surfaces (ceilings, wall, and woodwork) of a particular room done first, please let us know in advance.

Do you always prime a surface before painting?

Not necessarily. Priming is required in most cases to ensure the new paint adheres well to the surface such as when painting over gloss enamel and all new plaster and woodwork.

Switching from oil based to water based paints and vice versa requires priming as does painting over mold and water damaged surfaces.

If prepared correctly, most ceilings and walls do not require priming as long as it’s acrylic on the existing acrylic paint. If the existing colour is dark or a bright and a neutral colour is the goal, we would apply a coat of neutral colour primer first then 2 coats of topcoat.

Untreated drywall must be sealed with a suitable sealer prior to application of topcoats.

Interior – preparation

A good amount of preparation work is done in the painting process which includes cleaning wall and all other surfaces to be painted. We then sand painted surfaces, wipe off, srape flaking paint and scratch out widened gaps for filling. Lastly, we fill holes, gaps and cracks, sand and seal filler and bare surfaces.


We use primer when painting over gloss enamel, all new plaster, woodwork, switching paint types, mold and water damaged surfaces. If the existing colour is dark or a bright and a neutral colour is the goal, we would apply a coat of neutral colour primer first then 2 coats of topcoat. Untreated drywall must be sealed with a suitable sealer prior to application of topcoats. All other surfaces will get two coats of Dulux or Haymes Paint.

Exterior – preparation and painting

For brick or woodwork, mouldings, garage roller doors, downpipes etc. we pressure wash surfaces, sand, fill cracks and wipe clean. We then apply one coat of exterior primer and one coat of exterior paint.

Paint types

What kinds of paint do your painters use?

We use only the best on your property, this is typically Dulux or Haymes.

As a Dulux accredited company our preference is Dulux.

The kinds of paints and uses are as follows:

Matte paint

This has a chalky look with little or no shine which makes it great to hide imperfections but is least durable so is best for low-traffic areas and ceilings.

Satin paint

When light reflects off this paint it has a satin finish which makes it more noticeable than Matte Paint. Great for kid’s rooms, high-traffic area or areas where you need to clean walls.

Semi gloss paint

This has more durability and sheen than satin and works best for kitchens, bathrooms, and skirting boards. Its reflective surface helps darker rooms feel lighter and brighter.

High gloss paint

It’s the shiniest and most reflective of the finishes and its sheen is a standout feature of any room. Gloss paint’s hard surface can be used on cabinets or vanities although, it easily shows scratches and dirt.

Interior paints

For interior we use interior grade paints as they have lower levels of VOC (Volatile Organic Compounds) and are chemically formulated to withstand normal household wear and tear. Washability properties of interior grade paints is another important factor for suitability.

Exterior paints

Exterior grade paints are formulated to endure various weather conditions. Temperature fluctuations, sun UV, rain, moisture, salty sea air and wind carrying sand and small objects are examples of how environmental factors can deteriorate external finishes of a house.

Though nothing can overpower the eroding power of nature, paint manufacturers have developed some great products that can withstand harsh weather conditions for years.

Warranty / payment / insurance

How long is a painter’s warranty and what does it cover?

Trusted Painters offers a 10 Year warranty on workmanship so if anything goes wrong, we will rectify the issue or re-do the job. However, if cracking, peeling, bubbling or other issues are due to a fault in the substrate or structure, our warranty is null and void.

Paint manufacturers offer warranties from 5 to 15 years and in some cases a lifetime warranty.

Are you a licensed painter?

Licencing isn’t required in Victoria however all of the Trusted Painters team are highly experienced painters with many years in the profession.


Our quotes will state the timeline for the work, the labor required, commencement date and estimated project time. Generally payment terms are 10% upon commencement, 40% upon completion of 50% of project and 50% upon completion.

Choosing colours

How should I choose a colour for my home or office?

All paint outlets have colour charts for different paint manufacturers. All colours are cross referenced so even though the name may be different amongst paint manufacturers, the colour is the same. As colours you buy in-store look different at home collect your final choices in swatches to try at home. Put them on the wall in various locations like behind the sofa, next to furniture and curtains for 3 days and check them morning, noon and night to see if you are happy with your choice.

Using white paint

White paint has a variety of undertones which can transform an area from a cool, crisp feel to a soft warm one. It’s important to know the differences when choosing.

The undertones of white paint are:
Warm – yellow, pink, and orange which bring warmth and a welcoming feeling to more traditional environments.
Cool – blue, purple, or green work well in contemporary and modern, open-plan environments.

What COVID measures do you take?

All our team members are fully vaccinated. We regularly undergo covid tests with or without symptoms. If a team member is showing symptoms, he or she will be off duty until a test has been conducted.

All our staff sanitise hands and equipment regularly.

What do painters do on the first day of painting?

It really depends on the current condition of the house. Normally on the first day of work, we move objects away from walls, cover furniture, floors, cabinetry and surfaces that are not to be painted. We then inspect the wall for holes, cracks and dirt and carefully scrape old flaking paint. We then sand, fill, seal and prime before we can apply any paint. We also tape off places like window frames, tiled areas etc.
