Every year CJO Maintenance receives calls with requests and questions concerning their peeling deck surface and rotting deck boards. The cure to this is regular maintenance. It is the best economic solution to avoid costly repairs and construction.  The following are some of the factors that play into a weathered deck :

-UV rays from the sun will damage the wood resulting in fading of the woods strength and appearance. This will break down the stain while causing the wood to oxidize (turn gray). A sealer is recommended if your deck is in direct sun light at all hours.

-Water, snow, and ice will cause damage to the wood by breaking down the surface.

-Freezing/thawing will expand and contract the wood

-Mold, mildew, and algae will leave the wood unsightly/dirty and can result in rotting

-High traffic areas will leave “wearing” patterns.

-Previous stain used was applied incorrectly.

-The wood was not prepped properly prior to application.Bad prep is the number one reason stains prematurely fail!


New smooth decking boards are not porous enough for most stains to be able to penetrate properly. This is mainly due to:

-Mill glaze when cut

-High moisture content

-Chemicals in Pressure Treated Wood

A large percentage of the time it takes for us to restore a deck is the prepping of the wood to be stained. Sanding all old stain/paint off and down to the natural wood again. Even brand new wood needs to be prepped and sanded for the stain to take properly.



- Cedar 

The choice of a clear coat sealer is recommended for hardwood such as cedar. Cedar is not recommended to be stained.  

- Pressure Treated

A clear coat protector is a great way to keep your freshly stained decks survive many more years. 

Due to our winters, a large percentage of our decks are pressure treated wood decks. Because pressure-treated lumber usually has a greenish tint due to the chemical used in treating it, a clear sealer may not be the ideal choice. Sealers are best applied shortly after the stain.  Sealer is applied with a brush but can also be applied with a sprayer(we chose the brush). The advantage of a brush is that it tends to make better contact with the wood, filling any pores and offering a more inform spread. Clear sealer protects against wear and tear on the wood and will prevent some markings and scuffs as well.

Redwood and cedar are rarely stained, because they have such distinctive colors. Pressure-treated wood, with their lighter colors, can be stained to match your area or home. Stain varies from the lightest sand color to the reddish/orange of redwood. Stains are also applied with a brush or sprayer. Because stains are more of a liquid than paint it is able to get deep into the pores of the wood, unlike paint.

Degrees of Opacity

1.  NATURAL/TRANSLUCENT Allows the natural beauty of cedar to show through.

2. TRANSPARENT =  Gives the wood a tint of colour, allowing the grain and texture of the wood to still show through

3. SEMI-TRANSPARENT = Compliments the beauty of the wood with colour, still allowing some of the grain and texture to show through

4. SEMI SOLID = Colours the wood while partially allowing the grain and texture to show through

5. SOLID =   The colour covers the grain but  the texture of the wood will still show. Covers all imperfections.

Exterior paint is best suited for railings and baluster,   Depending on the amount of use the deck gets, it may need to be re-painted more often if walking areas are painted. . Instead of painting walking areas, a solid stain is recommended. 




To help prevent rotting and peeling and to keep up visual appearance, CJO offers a maintenance plan for those that are serious about their decks lasting with minimal expenses. A deck needs to be restored roughly every 3 years. Once the deck is sanded and stained, a great option is to apply a sealer after.

In addition to this we offer tarping in the fall season to help keep the snow and spring rain from penetrating all season.
