We had Semco windows installed when our house was built in 1989. Ever since, when the temp drops a certain degree we also get lots of condensation. When it gets cold in winters (we live in Wisconsin), then we get mounds of ice build up on the inside!! Gee, are windows suppose to have ice on the inside?? Needless to say, the wood around the windows is now rotted and moldy. I have to blow a fan on them to "melt" the ice. You can also feel the cold air coming in like a breeze. These are the worst windows ever and will never even consider using them again. Semco at one point tried to blame it on being a new house and lots of moisture. Nineteen yrs. later?? News flash, not a new house anymore. We even run a dehumidifier. They are no help at all about fixing the problem and yes, they do know the product is defective. At least I now know I'm not alone with this problem.....

Semco windows manufactured around 1990 had several problems.

One of the problems is that the pressure of the gas used to fill the space between the inside and outside panes of glass is lower than the atmospheric pressure causing the two panes of glass to deform. The result is that the spacing between the glass near the center of the window is very small in comparison to the proper spacing that you will have at the edges of the window.

The defect causes two things to happen. First, when it is cold outside, condensations will form near the center of the window pain on the inside of the house. This happens because the window is poorly insulated where the two panes of glass are nearly touching causing the glass to be cold enough to cause condensation. The second thing that may happen is that the windows may explode when the temperature is very cold outside.

Semco has known about the problem well before the warranty expired on the windows. What they can do is measure the spacing between the glass. If the spacing is below a certain tolerance, they know the window glass is defective. To solve the problem, they will drill a tiny hole into the window to relieve the pressure difference and after a minute or two they will seal the tiny hole. This will take care of the above problems and your family will be safe.

Unfortunately, you will end up with this tiny hole in all your window panes and sometimes the sealing of the holes is not completely effective and condensations will form inside between the two panes of glass as moisture can get inside. But it beats having your windows explode without notice.

The other problems with the windows are pretty well outlined in other posts. If you have Semco window manufactured around 1990, I share your pain.

We have a Semco casement unit in our laundry room, and other than having to bend the locking latches to line up a little better, they have performed well. These were installed in 2005. On the other hand, if I get a lot of time on my hands I will submit a lengthy post on my housefull of Kolbe and Kolbe windows, which are utter garbage. Avoid K&K products at all costs.

I am reading the threads on Semco windows and have to agree. We are in an 11 yr. old home, and 21 of our windows are rotted. Double casement windows where the sill piece is completely rotted through to the outside. Has anyone followed through with a class action lawsuit? How do we begin?

Howdy all,

Clearly I found my way to this site because some of our SEMCO windows also are failing. Our double-hung wood with aluminum exteriors windows actually are all doing well (15 out of 15 working without a problem...installed in 2004). The casement windows ( 3 of them) all have broken seals, with the interior of the double panes being filmy (seals broke within 1 year of installation). The company requires us to work through the window supplier rather than working with us directly to replace the glass only (as stated in the warrantee).

I wouldn't recommend the casement windows based on my (and your) experiences.

This house was built in 1997 by a reputable builder as a spec house. It has over 25 Semco windows, mainly fixed and crank out wood casement type with a 1 patio door and 1 exterior french door. Recently the home owner noticed that the sill on one of the crank casment windows was rotting. When I inspected the window I found that not only the sill has rotted but also the sash across the bottom and the window jam at the bottom on both sides.When I started to crank open the window in just fell apart. What remained of the sill appeared to be canted inward thus allowing water to run toward the wood frame. The wood trim around the jam was also rotting. I removed the window from the opening and found rot had spread into the framing of the house below the window open, which involved studs and other framing members as well as down to the base plate and the sub-floor. Total cost to repair this water damge is in excess of $2,500 and that is only 1 window. As of today, the inspection continues. I don't know what caused this failure, my guess is a a combination of poor quality window and faulty installation by the construction company. I did also note several other mistakes by the construction crew, so the owner is now deciding what she is going to do about all the problems recently discovered. Stay tune for up-dates as they become available

We built our Indiana home in 1996 and installed 15 Semco DH clad windows. From the start we experienced problems with the ease of opening and closing the windows, but neglected to file any sort of formal complaint. Our local supplier went out of business and the nearest dealer was more than 50 miles away from our home.

Last year, while experiencing numerous breaks and flaws with the block and tackle shoes in the jam liners we ordered several replacements. To install the little shoes, the jam liner needs to be removed. What we experienced during the removal of the jam liner was frightening. Lots of leakage and lots of wood rot as a result of faulty seals with the Semco window configuration. We can only imagine the total outcome of wood rot and devastation if we were to remove and inspect all our windows.

Come on who do you think you're fooling. I've been using Semco windows in all projects for the past 10 years. I've yet to have one problem worth mentioning. In addition any issues that have arisen have been handled quickly by Semco. I would highly recommend using Semco windows and doors. I hope anyone viewing this site to choose a window line can see through the lies here. Just out of curiousity I wonder if these people trashing a wonderful built product are employed by Semco's competition or are they just bored talking trash about something they know nothing of???

Semco is a quality product that the company stands behind. I've literally installed 100's of Semco windows and doors and NEVER have had a problem. Their customer service is excellent and they're quick to respond to any problems. Good luck getting someone from Jeld-Wen, Marvin, Pella, etc. to even respond to any issues you have. In direct response to get a lawyer if you have Semco product I say get a life and find out what you're talking about before trashing a reputable company. Again I know first hand this is a quality product and would openly invite anyone who doesn't think so to explain why they feel that way. I'm confident I could correct your false opinion with fact!!!!!
