Replacement Windows
in Milwaukee
and Southeast Wisconsin
If your home needs new windows, you want a team that explains your options clearly, shows up on time, and installs products built to last. SiDEX has helped homeowners throughout Milwaukee, New Berlin, and Southeast Wisconsin replace old windows with energy-efficient styles that improve comfort, boost curb appeal, and perform year-round.
You will meet with a local specialist, review window styles that fit your home, and receive a clear price before any work begins.
Who we help and
how we solve it
We install replacement windows for homeowners across Milwaukee and surrounding Southeast Wisconsin communities, tailoring each project to the home’s age, style, and energy needs.
Older homes with drafty or outdated windows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
Our team works in Milwaukee-area homes every week, so we’re familiar with local construction styles, window openings, and seasonal weather demands.
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.
These materials are well-suited for Milwaukee’s temperature swings, helping homes stay comfortable in both summer heat and winter cold.
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 window project is different. Pricing depends on the number of windows, window style, frame material, glass package, and any installation complexity. Your consultant will provide a clear, written quote after measurements and design selections are complete. Timelines vary by scope and scheduling, and promotional financing is available for qualified buyers.
