The Importance of Exterior Painting

Year after year, the seasons change, and your homes exterior surfaces are exposed to its worse enemies; moisture and sunlight. These two elements will continue to cost money if you do not have a preventative maintenance plan in place.

The problem with moisture and sunlight is that when a surface is painted, the paint film is resistant to water contact from dew and rain. The problem occurs when moisture gets in between the pain film and the surface. The pain film then weakens and it loses its gloss. The cold of winter and heat of summer will make the wall surfaces expand and contract. A quality paint film is going to withstand these changes in in temperature because of its flexibility properties.

Below are some of the most common problems that arise on the exterior of your home:


Alligatoring is patterned cracking in the paint film which resembles the scales of an alligator.


Blistering are bubbles that result from localized loss of adhesion and the lifting of paint film from the underlying surface.


Chalking is the formation of very fine powder on the surface of paint film during the weathering process, this can cause color fading as well.

Flaking / Cracking

Flaking or cracking is when the dry paint film splits through at least one coat, this will lead to the complete failure of the paint.


Efflorescence is often seen as a white fluffy deposit of salty crystals on any cementitious walls. It will also depend on the presence of moisture and salt.


Fading refers to the excessive or premature fading of the paint color, it will often occur on the exterior surfaces that face western and southern exposures.

Algae and Mildew

Algae and mildew are gray, black or brown areas or spots that are found on the paint film or caulk bead.


Peeling is when the coating or paint lifts from the surface because of poor adhesion. This may involve one or more coats.

Tannin Staining

Tannin staining is a tan or brownish discoloration that appears on the paint surface because of the wood tannins migrating from the substrate through the paint film.

Importance of High Pressure Washing

We strongly advocate High Pressure cleaning, High pressure Cleaners are awesome pieces of equipment to have because they can cut through grime in no time (yes, that’s right I just made a little rhyme) making cleaning your house or industrial area that much easier, and more enjoyable.

They are a necessary piece of equipment when coming to the ‘painting-your-building’ process, and we absolutely love them. Here’s why:

What is High Pressure cleaning?

High Pressure Cleaning is the use of high-pressure water spray to remove loose paint, mold, mildew, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces (in this case residential houses or industrial properties). A pressure washer is really less complicated than it sounds. It’s really just a water pump powered by an electric motor. The washer takes in water from a tap, the pump accelerates the water to high pressure, and then squirts it from a hose at speed through a trigger gun.

Why Pressure Jets get Things Cleaner?

in fact, did you know there’s a good scientific reason why water gets things clean so productively? What happens, is that the water molecules have a bit of an electrical polarity (one end is positively charged and the other end is negatively charged), this is the reason it sticks to things so nicely. Of course, you can add detergent to the water to help it break down the grime and grease and help you clean things even further. But what happens when detergent doesn’t work? there are some forms of ground-on dirt that just won’t go away. This is when high pressure cleaning comes in handy.

high pressure cleaning uses a very narrow jet of hot or cold water blast the tough dirt away. the water is travelling very fast, it hits the dirty surface with a high kinetic energy, knocking dirt and dust away like a constant rain of tiny hammer blows. But you’re afraid it might damage your surfaces? No, even though it boasts a great amount of pressure, it’s still only water, and is therefore kind to most hard surfaces. Although, it’s still a good idea to test the jet on a less conspicuous area before you start working for real.

Why is High Pressure Cleaning Important?

Hydro washing is important, because it removes old and layered peeling paint coatings, it removes mold and mildew that has developed due to weather conditions, it exposes a lot of defects ie cracks, bad plaster and damp which is disguised by old paint. removes chemicals, oils and other elements that adhere to surfaces, it removes dirt and mold which over time can erode building materials.

Pressure Washing is absolutely necessary for Surface Preparation.

If repairs re needed to surfaces, high pressure cleaning clears the surfaces properly before coatings are applied. By eliminating unwanted elements and chemicals new applications can sufficiently adhere to surfaces. This provides superior adherence of coatings, finer finish coatings and a maximum duration of product applied to surfaces.

Using a High Pressure Cleaner Correctly?

High pressure is not necessary in every situation. Using high pressure cleaning on the wrong elements of your house, like PVC or soft wood can actually damage your house and leave it unsightly. An experienced high pressure cleaner will know when to use high pressure, and when to turn down the nozzle. Good cleaners should rely on the right amount of pressure, and good cleaning to get the job done. Which will result in your home looking thoroughly clean and undamaged.

So, if you’re going to ‘vote’ High Pressure cleaning, don’t just choose any old Joe, or fool. Make sure you choose a trusted professional, and somebody who knows what they’re talking about.

What is the Difference between Structural and Non-Structural Cracks

You know what it’s like? You walk outside your home, take a look at that seemingly harmless crack on your wall, and then all at once on your lovely summer’s day, you start to worry.  Don’t worry, were here to help. While it is true that that minor cracks can turn into bigger cracks to threaten the structural integrity of your home, and that every crack should be taken a look at by a professional, there are differences between structural and non-structural cracks that you can view here below..


These are small less that 3mm in diameter cracks, that do not at the moment threaten the integrity of your home. They appear in your foundation.  Weather conditions, temperature changes and moisture content naturally cause your foundation to experience these cracks.



Some of the factors that cause non-structural cracks are:

  • Creep damage
  • Shifting foundations
  • Hydrostatic pressure
  • Settlement
  • Vegetation or trees

Like we said before, not all cracks are initially threats to your home’s structural integrity, nevertheless they should be monitored and treated very carefully off the get go, as water can seep into these cracks and start to erode your homes inner concrete.


There are a number of different issues that cause structural cracks, like swollen soil, poor soil bearing, poor construction sites and overloading.  You can tell if you have structural cracks, because you will have problems on the inside of your home, like sloping floors and windows sticking when you close them.

Generally, structural cracks appear wider than 3mm in length. They can appear in the wall beams, foundation walls or slabs. And they usually extend to the upper floor of your house. They can be vertical, horizontal, diagonal or run like a staircase.

How to Address Structural and Non-Structural Cracks.

Non-structural cracks should be monitored and taken care of so they don’t get worse, they are usually repaired with an injection of a sealant resin, this resin protects your foundation from future leaks and prevents the problem from worsening.

There are a number of methods that can be used to fix structural cracks:

  • Injecting the crack with urethane to permanently seal it.
  • Install carbon fiber strips to damaged walls.
  • Using resistance and helical piers to level sinking and settling foundations

How to pick paint colours for the outside of your home.

Everybody wants a great looking house, and you can imagine it in your head ‘the way the colours fly off the palette!’, but real life can be a different game sometimes.

Do you ever remember walking down the street as a teenager and screaming in laughter at a crazy pink house?

Or seeing a house, so dim-drab grey as you rode past it it just knocked you into the cold recessions of your consciousness?

There are a number of problems to deal with when painting your house in a neighbourhood, being too bland or colourful or but just a few.

These are not the only problems; there are other hurdles as well. Like landscaping, hardscaping and roofing, not to mention homeowners association guidelines or not stepping out onto your pavement and getting that ugly look from Goerge your (not so funny) neighbour because you painted your house the wrong a colour that doesn’t suit theirs or entertain the neighbourhood’s taste.

Where do we get home from here?

There are a few simple rules to observe.

The truth is painting your house the right colour will not only bring out its best characteristics, but will also hide its design flaws and elevate its market value.

Three in One

Generally a paint scheme has three major shades: field, which dominates (most of what you see at first when you look from the street), accent, which brings all the little areas of your house to life, like doors, shutters and etc. And your trim, which highlights your roof edging, railings, window and door casing.

Your field colour should dominate your choice of accent, and trim.

Are you wanting your house to look more prominent on the street? Then you want to go with painting it a light colour. Light colours can add a sense of size and dignity to your house. There’s a reason why many grand estates are painted white.




Do you want more drama?

Then you want to paint your house a darker colour. Darker colours will shrink your house, but give it a stronger, more solid appearance.




Your trim colour is also very important.

Usually, you want to paint your trim a different colour, and a colour that contrasts strongly with the field colour. But this is not always the case, and in some instances people do paint their trim colour the same as the field colour but sometimes, this is not to work and it gives the house a a rather ‘unfinished’ look. Your safest bet is most always keeping the trim lighter than the field.

Although for stunning little effects:

You can either (a) touch your light field with a dark trim, giving it an ‘eyeliner’ kind of effect on your home.

Or (b) paint your light field with a dark trim giving your windows a ‘picture frame’ effect and making them look like they were hung up. Also very visual.

So, what should we do with the accent colours?

Accent colours can be fresh and exciting. Feel free to go bold with them, but don’t go overboard.

Remember that, a door, a shutter or a window frame painted in of those fresh and exciting colours can look very enticing, but not so much when you start to extend it to all the other little places that shouldn’t have it. Remember when your little one drew something lovely in that bright colour, and you thought it was just too adorable? But then they started to draw it on the walls, the kitchen and all the other very valuable surfaces that you call a home.

Good places for accent colours, are doors, shutters and window frames.


What are the most important things to remember when choosing a colour scheme?


Whether you have a Victorian, Tuscan or Modern style home, it is good advice to generally observe the style and era guidelines. This is not to say, that every house shouldn’t have its own personality, but not all houses look good in ‘party dress’ all the time.

If you’re a little confused about this, remember that many paint dealers offer a great collection of accurate colour combinations. There are also excellent professional services that specialise in this area, that you can call on anytime.

Neighbourhood awareness is also a big thing. Remember that your neighbourhood, in some instances will have a certain style and a cultural feel. It might be a good idea just to adopt a tip or two, from that. Before your neighbours come running down the driveway with long sticks in their hands. In other cases you might have upset your neighbourhood homeowner’s association rules, and guidelines. Not every neighbourhood has one, but you would do your best just to check it out.

Look for the unchangeable.

Many people don’t take into consideration certain foundations of their home when painting, and don’t think they will play a part in the colour, but they do. For instance: Have you ever thought about the effect the colour of your roof would have on your painting your house? Do you plan to paint your roof over, again? Or are you just going to keep it the same colour? What about your driveway?  Do you have a brick or a stone driveway? What colour are those bricks or stones? What kind of property do you have? Are there a lot of trees and rocks on your property? Have you taken those into consideration? Nature can be a great informant to your palette. You may find underlying tones undertones of brown and green.

Try it first!

Painting the outside of your house is a bigger deal than painting a room, so you will want to be extra diligent with the colours you pick, the way a paint colour looks on a chip inside a store varies greatly from the way it will look in the natural light or an a large surface.

Painted on large surfaces paint begins to look lighter, natural light also changes the way paint colour looks. Chances are you’ll need a much darker colour than the one you first picked.

Get a colour wheel and choose a few colour schemes, then buy a quart of each colour – and a quart of several other colours that are nearby on the colour strips (due to above reasons). Buy quarts before you buy gallons. Most paint stores sell quarts of paint at reasonable prices so you can try out several colours or colour combinations before you commit to a scheme. Find an inconspicuous area (the larger the better) area of your house first, and try them out. Let them sit in different times of the day and night (also in varying weather conditions) so you can see how they look.

Extra Tips

  • Contrasting colours can be nice, and this can draw attention to architectural detail, but at times can clash so badly that it actually retracts from the detail. Be flexible and be willing to experiment, but remember that staying within one colour family is the safest. Instead of using a different accent colour, why not use a lighter or darker shade of field colour?
  • You can find inspiration in the inside of your home for a colour scheme too. Look at your living room and your furnishings. Harmonizing the inside and outside of your home can be a great way to find a match that works.
  • Sometimes flying in the face of the past can be just what you need. Painting your old architectural a house a bright and vivid colour can bring effective and astonishing results to detail. Check out older houses who have done this for the cue..
  • The more intense a colour is the more likely it is to fade, sometimes even change colour altogether. On the other hand, dark colours absorb more heat and suffer more moisture than light colours. These pose more of a maintenance threat. But they don’t show dirt so easily. Think about how you can add longevity to colours when choosing them?

No matter how you feel about picking paint colours, there is always a mass of help out there. Most of paint stores have pre-selected colour palettes arranged by style and colour range that specify just the right, necessary field, trim and accent. Some paint stores even have online programs that show you how to pick the right colour. Visit your local friendly paint store today for top advice!

We look forward to seeing you there..
