BV000855 -- you should go to the Kolbe website and find their care and use guide. All the info you need on finishing them should be in there.

I have 1993 Kolbe Classic double hung windows and my siding is conventional Stucco, light color. I have had staining under the windows which is impossible to clean off the stucco. It shows up on the outter edge as well below the joints of windows that are installed together.

I am tring to find out what causes this? I am currently considering a paint job or re-dashing the house. Any thoughts or advice?

The staining is caused by water the collects in corners of the trim/window and drip down to the stucco. It has nothing to do with the windows it self, just water. Power wash the stucco, but DO NOT power wash the window.

I am in the process of investigation a claim against Kolbe for a client. I would be interested in speaking with individuals that have been dealing with Kolbe over their defective windows. Please contact me if you are interested - my email is

My experience: Kolbe&Kolbe manufactures very attractive windows from the wood of young, immature trees resulting in a product that has about the same strength as balsa wood. Soft, wet wood rots fast.

The sashes are not painted or sealed, leaving the homeowner at a further disadvantage bc there is no protective barrier against the elements. Soft, wet, unsealed wood rots especially fast.

Ten years (& many rotted sashes plus one $15,000 rotted-window) later, Kolbe&Kolbe explains that ultimately the builder is to blame for not installing the products at a slight angle to allow moisture to run down & off the product. The builder, of course, blames Kolbe&Kolbe and offers to paint the replacement (for a price) b4 installing. Despite the failure rate, the builder continues to represent the company bc of its quality product line.

P.S. I would advise AGAINST power-washing stucco!

Hi Skinny. Would you be willing to speak with me regarding Kolbe's response to your complaints?

Rotting sash is usually caused by condensation on the inside surface of the window. Read posts for all different brands and read technical literature and you'll discover this condensation is not the fault of the window construction, but other factors within the home.

Here are just a few:
--Homes are insulated very well nowadays which is a double-edged sword. Air tight homes retain moisture, which ends up causing condensation on windows.
--If you have blinds or curtains pulled, the air in the room won't circulate and condensation -- even ice -- will form. This will happen no matter what brand of windows you have.
--Showering and cooking while not running external exhaust fans can exacerbate the problem.
--Condensation can happen more frequently in bedrooms if you sleep with doors closed, since you exhale water vapor when you breathe.

Andersen Windows has a really great video that helps explain condensation, why it happens, and how to prevent it

Here's the take-away from the video:
"Condensation doesn't mean there's a problem with your windows. In fact, the presence of condensation could actually be a sign that your windows have good, tight seals. Everything that makes homes more energy efficient also locks moisture inside your house and increases the chances of condensation forming."

Have installed Kolbe windows in two previous homes and loved their windows and patio doors. Both installs were the aluminum clad outside, wood inside, on patio doors, double hung windows and a casement window. Homes were in Louisiana and windows went through several hurricanes! Would buy Kolbe again.
