Ahh...window boxes, who doesn't love them.  There's nothing more beautiful than a house lit up with window box all over the front.  There's only one problem with that, most windows vary in size and this means finding a window box that accomodate three or maybe four different window sizes.  A lot of window box manufacturers nowadays make window boxes only in a few sizes or sometimes only one size!  This is great, if that happens to be your size, but how often is that actually the case?  The solution to this is to bring in the custom window box guns and get them done right.  There's nothing worse then putting a 60" window box on a 66" window, because that was the closest size the manufacturer made.  Custom window boxes also add value and curb appeal to your home and they will most definitely be unique.  There are a few custom window box companies out there that can get the job done.  Make sure you ask the right questions such as: how long will it take?  How will it look? Are there any additional fees for custom sizes?  Will it be structurally sound?  Will it still drain properly?  Will it install differently?

Another thing to note, is that if you're going to spend the money on custom window boxes, you should definitely find out how long the window boxes generally last.  Many wooden window boxes are gorgeous, but can rot out in 2-5 years.  PVC window boxes can cost a fraction more and last for virtually forever without any maintenance.  There definitely a smart investment for custom window boxes if you plan to live in your home for several years.
