"Hi Dane, we're replacing our old double-hung windows and trying to decide between vinyl or fiberglass. We have quotes on the Marvin Essential and are waiting on Marvin Infinity.
Here are the installed quotes we've received so far. The first four are for 15 double-hung windows, while the Renewal by Andersen quote covers only 12. The Advanced windows are through Semko windows.
Advanced 6300 vinyl — $16,000
Soft-Lite Imperial LS vinyl — $20,000
Marvin Essential fiberglass — $24,000
Marvin Elevate wood/fiberglass — $30,000
Renewal by Andersen composite — $37,000 (12 windows)"

Editor's Advice:
Steve, I like the Soft-Lite Imperial a lot. However, the jump to the Marvin fiberglass is pretty reasonable. Finally, if your timeline is 15 years or less in this particular home, then the call is the Advanced 6300 vinyl window. Semko Inc., who sells the Advanced Window Corp 6300 series, gets great reviews and this is a nice option.

Semko Windows vs Kolbe
| Window Series | Total Quote Installed | Average Installed Cost |
|---|---|---|
| Semko Windows | Less Than Marvin | Not Provided |
| Kolbe Windows | Not Provided | Not Provided |
| Marvin Windows | Higher Than Semko | Not Provided |
| Pella Architect | Not Provided | Not Provided |
"I had a chance to compare the Kolbe and Semko windows and found the Kolbe was much thinner, both in the frame and the sash. It also used a compression sash, although and I liked the Semko tilt latch. The Kolbe was rolled form and the Semko window option was the extruded aluminum, which I thought was much better. Also, Semko had way more exterior colors to choose from, I thought they were the better product, hands down.
Comparing the Semko and the Marvin window was interesting as well. The cut away comparison showed the Semko was a thicker window, with more wood used in the frame. Besides this, I found the quality similar, but the Semko is quite a bit less compare to Marvin windows cost.
As far as Pella windows go, I thought their cutaway and thought their Architect model looked cheap. It was really thin and sort of flimsy. The salesman kept saying how great they were, but just from the product demonstration I was not impressed."

Editor's Advice:
Dave, thank you for sharing this detailed comparison. These kinds of side-by-side showroom observations can be very helpful for homeowners who are trying to understand the real differences between frame construction, sash design, exterior cladding, and overall build quality.
Your comments are especially useful because you were able to compare Semko against Kolbe, Marvin, and Pella in person rather than just looking at brochures or online specs. Product feel, frame thickness, cutaway samples, and hardware details can make a big difference when choosing between premium window brands.

Semko Windows Reviews
| Window Series | Total Quote Installed | Average Installed Cost |
|---|---|---|
| SEMCO Wood Interior / Bronze Aluminum Exterior | Not Provided | Not Provided |
| SEMCO Replacement Glass Warranty | Glass Covered | Labor Not Covered |
"In 2003, I purchased 16 casements, a double hung, and 8 fixed windows plus 2 sliding glass doors, all from SEMCO. The interiors are all wood finish and the exteriors are bronze aluminum. So far I like them, I expect to replace a few more with SEMCOs so they all match. We've been mostly happy with them, but our south facing windows have had some seal failures and sometimes fog up. 4 of 16 casements and 2 of 8 fixed have had their glass replaced because the low-e coating was deteriorating.
In addition, the glass is covered under warranty but we had to pay for labor. Our summers are really hot, we're in SoCal, so I don't know if anyone else's windows could hold up better in our heat. We bought the wood vs aluminum clad SEMCOs because they were so well priced. I think even with some minor problems, I'm glad we got them, because we could get the whole house done and we could never have afforded that in any other brand."
Bret - Homeowner - from 2020
Editor's Advice:
Bret, thank you for the detailed long-term feedback on your SEMCO windows and doors. This is helpful because it shows both sides of the equation: the windows allowed you to complete a large whole-house project at a more affordable price point, but the south-facing units did experience some glass and seal issues over time.
The fact that the glass was covered under warranty is good, although labor costs can still add up when multiple units need service. In a hot Southern California climate, sun exposure can be tough on any window, so your experience is a useful reminder for homeowners to ask specifically about glass coverage, labor coverage, and how south- or west-facing windows are handled under the warranty.

Semko Homeowner Review
The builder I've been talking to always uses Semko windows, and I don't know anything about them. I haven't been able to find much on the internet, mainly some complaints about windows that are 10 years old or more. I can't really afford to upgrade to a more expensive window, but I do want a quality product since I plan to live in this house a long time.

Semko windows are a low budget option, and they're going to have to be replaced in 10 years or so. If you really want a wood window, Marvin and Kolbe both make nice ones. Marvin is more expensive and more well-known, but the Kolbes are excellent.

Options For Aluminum Clad Windows
I'm looking for an extruded aluminum clad window for a house with a stucco interior. I want the best windows I can afford, but I do have a budget. I'm considering SEMCO, Marvin, Windsor, and JeldWen, but I like the Semko and Marvin best. The Windsor and JeldWen are kind of plain and generic looking, and their movement seems less smooth. The Marvin and Semko seem to have better hardware.

I've been in the industry for over 25 years, and I've never sold a Semko and neither has anyone else I know. I can't say anything else about them, I really don't know if they're any good. I do know that the Marvins are good and you can't go wrong with anything from them.

I have Loewen windows and Marvins and like them both. It's a whole lot cheaper in the long run to buy good windows once than to replace cheap ones every few years. If I was building a new home and the contractor recommended Hurds or Semko I'd walk away and find somebody else. They aren't good, and you can get much better ones without spending a whole lot more.

Semko Aluminum Clad
I like aluminum clad windows better than vinyl. They handle temperature changes better and don't sweat. Semko has decent aluminum clads for a fair price.
