Purchased windows and patio door in 2014 and gave them a five star review for product and installation..After 4 yrs, we noticed a small crack in one of the windows, one call and we were told that the window would be replaced at no charge...one week later, they arrived and replaced the window in about 10 minutes...Great service again...it is no wonder why they have stayed in business so long...Great customer service and stand by their product..

Spoke with Jason on the phone and explained to him what we needed....Jason arrived at our home a couple hours after our phone call.....measured our windows and patio door....gave an estimate..and completed the order....Very friendly in explaining how long they had been in business and what the complete cost would be.....Weeks later we got a call to set up a installation time and the crew arrived as scheduled...completed the install.cleaned up all the debris, and explained the operation of the new door and windows....Very pleased with the quality of the work as well as the product....

So you can see why SEMKO is such a breath of fresh air (pardon the pun!).

Semko is amazing- my husband and I had a very bad experience with another window replacement company so we were very wary.  As an experiment we replaced just 3 windows and the results are FANTASTIC.  We had special concerns and they were accomplished - Semko will now do the entire back porch next year.  5 stars. This company listens and is very helpful.  Go local!!

I called another company for replacement windows. The salesman was very nice, but he was in my house for almost two hours, and his initial estimate was a bit high. I called Semko. The son of the owner was the salesman (Sorry, can't remember the name). He spent all of fifteen minutes at my house measuring each window, and then he gave me a price. About twenty percent under the other company. The windows were installed two weeks later by a very efficient crew, and the windows themselves are almost exactly the same as the windows another company showed me. Excellent company.

OUT-KCUFING-STANDING!  If you go anywhere else for windows your a fool.  From the moment I made the first call to Semko to they walked away when the job was done I've been in awe of their professionalism with a no pressure laid back attitude.  The quality of the workmanship and windows is top notch and only took a month to have the windows custom made and only 6 hours to install.  We had priced other companies and they were almost twice as much AND sent a pushy salesman with smarmy tactics like attempting to play off of two people and refusing one on one quotes.  When I need the other half of my house windowed I know where I'm going: Semko

Not only did they replace 10 windows in my house, they also created a hole in the wall to add one more. They did a terrific job! The workers are considerate and professional, and the price is very fair. Very good quality windows. No hassle, just straightforward and honest. Jason is a down-to-earth, responsive and friendly representative for this local, family-owned business.
