Who we help and
how we solve it
Older homes with drafty or outdated windows
Wood rot, failing seals, and thin glass make older windows hard to open and expensive to heat or cool. We replace worn windows with modern, energy-efficient styles that seal properly, reduce drafts, and make your home more comfortable year-round.
You’ll see clearer views, easier operation, and long-term savings through better insulation.
New homeowners wanting a fresh look
Sometimes the house is perfect, but the windows date everything around them. We help you choose styles that match your aesthetic, from classic double-hung to modern picture or casement designs, without overwhelming maintenance.
You get windows that look sharp, function smoothly, and improve curb appeal right away.
Long-time residents ready to improve efficiency
If you’ve been thinking about updating your windows for years, now is the time. New insulated glass and tight-sealing frames help reduce energy loss, lower utility bills, and make rooms more comfortable in both summer and winter.
We guide you through style, material, and finish options so you get windows that enhance comfort, value, and day-to-day living.
WHAT TO
EXPECT WHEN
YOU HIRE SIDEX
Your project begins with a free in-home consultation. We take measurements, look at your existing windows, and discuss styles, frame materials, and glass options that fit your home and goals. You’ll receive a clear written proposal with scope, price, and an estimated installation window. On installation day, we protect nearby floors and furniture and carefully remove your old windows. We inspect the opening and framing; if we find soft spots or air gaps, we address them before installing the new unit. Your windows are leveled, insulated, and sealed to ensure smooth operation and proper energy performance. Trim is replaced or reinstalled for a clean finish. Before we leave, we walk you through how to operate and care for your new windows. We thoroughly clean the space so that everything looks tidy and ready for use.
Materials That Make Life Easier
Our replacement windows are built to perform in Wisconsin’s changing climate. Each style features insulated glass and tight-sealing frames to reduce drafts, improve comfort, and help manage seasonal heating and cooling costs. The materials resist swelling, cracking, and fading, so your windows look good and operate smoothly for years with little maintenance.
Local Accountability Without The Runaround
With SiDEX, you work with a Wisconsin-based team from start to finish. Your in-home consultation, scheduling, installation, and follow-up are all handled locally—no call centers, no endless transfers. Our installers are trained on the exact systems we offer, so the bathroom you choose is installed correctly and backed by people who understand Wisconsin homes. If you ever have a question, before, during, or after your remodel, you call the same number and talk to real local staff who know your project. Homeowners choose SiDEX because they want dependable communication, familiar faces, and support that doesn’t disappear once the job is done.
Permits, Plumbing, & Code
Some window replacement projects require permits, especially if framing changes or structural repairs are necessary. If permits are required in your municipality, we’ll guide you through the process to ensure everything is completed correctly.
Care & Maintenance
Your new windows are built for easy upkeep. Most styles tilt or lift for simple interior cleaning, so you can wipe the glass with mild soap and water - no specialty products required. Frames resist staining and do not need painting or sealing. We’ll leave you with care guidance based on your window style so you can keep them looking and performing great year-round.
Cost-timeline-and-financing-icon
Every bathroom is different. Price depends on the wall system you choose, the type of glass, any plumbing moves, and accessories like seating and grab bars.
Your consultant will provide an exact quote after measurements and design are complete. Timelines vary with scope and scheduling. Promotional financing is available for qualified buyers, and we can review options during your visit.

Reviews from Real Customers
First contact with the salespeople, Rob and Joe, was a delight. No hard sell. They listened carefully to my needs, asked great questions and developed a plan. For an added layer of reassurance, they gave me their numbers in case I had further questions/problems.
Within the time frame they estimated, Jenna came to measure the job.
Then Steve arrived to do the work. He worked straight through the day and into the evening to finish the job in one day! His workmanship was excellent. He was personable, courteous and very knowledgeable. He found problems from a previous remodel and fixed them.
Communication throughout the process by all involved was great.
Most impressive of all was that each employee spoke highly of their company and SiDEX’s owner. That pride and enthusiasm for an employer is seldom expressed nowadays.
This company and their employees ROCK! I am thrilled with my new bathroom shower and highly recommend them for your remodeling needs.
We moved into our house in 2016 and have had many door to door salesmen attempt to grab our pockets. A few years ago, Sidex came knocking and at the time windows weren't on our "to-do" list, however we entertained the free estimate for future planning. The price seemed astronomical, however it was for all 22 windows and we had no other bid to compare it to, so although it seemed high, it was a missed opportunity; windows only increase in price. Fast forward to this year, our old windows hadn't healed by themselves. Most of the windows didnt open, had broken locks or didnt stay closed/would fall from the top down. We knew it was time. A big window chain came knocking (you know the one) and we figured it was time to get serious. Their price was SO FAR above from the price we had received from Sidex just a few years prior. We thought we must be doomed to live with the broken windows a few years longer. That is until Sidex gave us a second, unprompted, knock. And we welcomed them in for the second time. Their number was higher than the last time, however with inflation this was something we anticipated AND it was half the price of the big windows chain (you know the one).
The only negative was, with any construction, there's always tiny bits of scrap leftover. Our house has rocks all around the outer perimeter, and while doing the spring gardening we did see slivers of aluminum wrapping sprinkled here and there. That is a drop in the bucket compared to how happy we are with the windows. Our house feels so much more secure being able to lock and double lock. I'm not scared to open the windows anymore, for fear that they won't ever properly close again. I would absolutely recommend Sidex for your project, should you be able to afford the help of a qualified hired hand 😊
was friendly and professional and went the extra mile in making sure everything was prefect.
