Our woodwork is stronger and longer lasting than woodwork produced by others.  Why?  Because we use better materials

Western Cedar is a great outdoor use wood that has been the standard throughout the US for many decades.  Usually when people say simply “cedar”, this is the wood they are referring to.  It is highly resistant to decay and very beautiful, and we use only CLEAR Western Cedar so there are NO KNOTS.  You simply cannot find a better grade of wood (because it doesn’t exist)!  This results in very beautiful, and very stable millwork.  Our Western Cedar consists of both Western Red and Incense cedars.

Mahogany is an excellent choice for those wanting a hardwood product.  It machines to a smoother finish than Cedar, and of course is stronger, denser, and harder which means it will hold up to abuse better than most other materials.  It is an exceptionally beautiful wood that can be either painted or stained with great success.  Most pieces are a dark reddish-brown color.  And it’s highly rated for natural rot resistance, making it a good choice for exterior as well as for interior applications.


Frequently Asked Questions:

How far apart should they be spaced to meet building codes?
To comply with the “4-inch ball rule”, use the following rule of thumb for 1 5/8″ square balusters: every 5 1/2″ on center (which gives a 3 7/8″ space between them, ensuring building code compliance).

How many balusters do I need?
Take the length of your rail (in inches) and divide by 5.5″. (round down for decimal answers)
Example: 10′ of rail, which is 120″.  Take 120 divided by 5.5 = 21.8, so 21 balusters needed.

What height of baluster do I need?
