Is a balustrade the same thing as balusters?

Balustrade is the architecturally correct term for a complete rail assembly, i.e. the complete configuration of a top rail or handrail, bottom rail and balusters (the vertical pieces between the handrail and bottom rail). It excludes the deck posts and post caps that may be part of the deck perimeter.

How far apart should I space my balusters?

In general, International Residential Code (IRC) requires that the space between balusters be less than 4”. To accommodate for decorative details, this includes the widest space between balusters – not just the gap between baluster bases. Since codes vary greatly from state to state, you should always check with your local municipality before installing or updating a deck and/or the balusters.

I have an existing deck with wood balusters. Can I take the balusters off and replace them with another kind?

Replacing your wood balusters can significantly change the look of a deck. This can be done by first removing the wood balusters; cutting them in the middle and removing the top and bottom sections of the wood baluster.
If installing face mount pickets that are the same size, all you will need to do is follow the products installation instructions.
If installing balusters that mount inside the rail, the top rail will have to be removed before the new balusters can be installed.

Do I have to install handrails or balusters on my deck? Or is that just required if I have children?

Handrails may be required for your deck depending on your location. Codes vary greatly from state to state, you should always check with your local building department before installing or updating a deck and/or balusters. In general, the International Residential code (IRC) requires a deck, porch or balcony to have a structural railing installed in order to pass a home inspection. For child safety, the balusters must be spaced less than 4" apart.

My deck is made with pressure treated lumber, can I still install balusters?

Pressure treated lumber (ACQ) is corrosive to aluminum. Although most aluminum balusters are powder-coated, you will still need to use a baluster connector to create a barrier between the wood and the baluster.
