How To Install Window Boxes
All of our window boxes
are made from SOLID 5/8" material (not hollow) and designed to be
installed so that they are integrated into your home and they are
installed in the safest, most reliable manner. At times, window boxes
over 48" long may need to support up to and more than 100 pounds
depending on how you pot and plant them. For this reason, you should be
wary of many of the simplistic bracket
and cleat systems on the market today which are not necessarily
designed to support these kinds of weights and are a major liability and
safety hazard. Cleats will trap water, mold, and mildew behind the box
leading to water damage and costly repairs to your home down the road.
Avoid these systems at all costs and rely on our cleat-less system
that's just like the pros do it. It doesn't get any stronger.
PICTURE>> Our boxes are made from stronger materials than the
competition who either use hollow material or 1/2" instead of 5/8"
material. No warping, cracking, bowing, or distorting over time.
Overbuilt to get the job done and backed with a lifetime guarantee.
DEMO Only: Please don't try this at home ;)
Our window boxes are designed to be installed exactly how a professional
would do it and it's easy enough for a do-it-yourself enthusiast to install in
minutes (see video below). All of our
PVC window boxes are installed using lead anchors and lag bolts which lock the boxes to the studs and load bearing portion of the home. This keeps your window boxes from having any
exposed fasteners and allows you to install on brick, siding, stucco,
or even rock for the gaurantee safest and most secure method available
on the market today! Once installed you can seal the box to the home
with a clear silicon caulk adhesive which prevents water from getting
trapped behind the box and wrecking havoc on your beautiful home.
Measuring Windows for Window Boxes
When measuring your windows to determine the size of your window box
needs, a good rule of thumb is to get a window box that matches the size
of your window or one that matches your window plus your trim. This is
especially true when you have a wide trim around your window which
makes the window look bigger. You can rarely go wrong by getting a
window box that matches your window.
However, when you get a window box that overhangs your window by a few
inches this helps create the right balance of window box and window
without the window box looking undersized or swallowed up. This is even
more true if you have shutters, which tend to make the window look
bigger than it actually is. We generally recommend that you go 4-6
inches larger than your window sill in these instances (2-3 on each
All of our listed sizes are for the base boxes (not including the cap or
trim on the top or edges). Any additional trim that overhangs one of
our boxes is not added to the size of the window box. So for example, a
36" traditional box is built as a 36" box with a cap that overhangs
about 1.5 inches on each side (making it 39" at top). Generally, when
looking at a window box you see the box, not the trim. It's a good idea
to get a window box at the desired length and not worry about the cap
or trim unless there is a critical dimension you cannot exceed (sometimes
shutters hang lower than the window). If you have any questions about
measuring, please call 888-505-7715 or email us. Remember, we do
custom window boxes with no additional custom fees. If you think you need a window box
length that's not already in our shopping cart give us a call and we'll

Note: All three windows are the same size, yet all three window boxes are different sizes that we would recommend.
