If you’re standing on the precipice of a major home renovation and new windows are on your list, you’ve likely felt the analysis paralysis kick in. I’ve been there. After countless hours of research and getting quotes, I landed on Feldco.
For my fellow homeowners in the Midwest who need windows that can truly handle the dramatic swings in our weather, I believe you should seriously consider them.
This isn’t just another review; it’s the story of my home’s transformation and a guide to help you decide if it’s the right choice for yours. Let’s get into it.
My Journey With Feldco Windows

Our old windows were, to put it mildly, a disaster.
They were the original single-pane wood windows from the 1980s, and they were failing spectacularly.
You could feel the drafts from across the room in winter, and our summer energy bills were astronomical as the air conditioning fought a losing battle against the heat seeping in.
Condensation was a constant issue, leading to peeling paint on the sills and a general sense of dampness.
The final straw came during a particularly nasty winter storm when one of the window latches finally gave up, and the wind howled directly into our living room. It was time for a change.
My search for a window company was exhaustive. I talked to national brands, local contractors, and everything in between. What drew me to Feldco initially was their reputation in the region.
They weren’t a faceless national corporation; they felt local, focused on the specific challenges of Midwestern weather. The initial consultation was a refreshing experience. The representative wasn’t a high-pressure salesperson.
Instead, he took the time to inspect each of our old windows, explaining precisely why they were failing. He used a heat lamp to demonstrate the difference in thermal resistance between our old single-pane glass and their double-pane, argon-filled windows.
Seeing that tangible difference made a huge impact. He walked me through the options – double-hung, casement, picture windows – and helped me choose what was best for each room without upselling me on features I didn’t need.
The quote was comprehensive and transparent, breaking down the cost of each window and the installation. There were no hidden fees or surprise charges, which gave me a huge sense of confidence. We signed the contract, and the journey began.
The Positive Side: What I Love About My Feldco Windows?
When you make a significant investment in your home, you hold your breath a little, hoping you made the right call. With my Feldco windows, I can exhale.
It’s been a few seasons now, and the benefits have been more substantial than I even anticipated. The improvement in my home’s comfort and my peace of mind has been remarkable.
- Unbeatable Energy Efficiency

This is the big one, the reason most of us bite the bullet and replace our windows.
I can tell you firsthand, the difference is not subtle.
The first winter after the installation was a revelation.
Those drafts that used to snake their way across the living room floor?
Gone.
The cold spots near the windows where you’d need an extra blanket? Vanished. My thermostat is now set at a consistent temperature, and the furnace runs noticeably less. I tracked my energy bills, and I saw a reduction of nearly 25% in heating costs that first winter.
The summers are just as impressive. Our home used to turn into a greenhouse on hot, sunny days. Now, the house stays significantly cooler, and the air conditioning doesn’t have to work nearly as hard.
The Low-E coating and the argon gas insulation between the panes work exactly as advertised, reflecting the sun’s heat away from the house. It’s not just about saving money; it’s about a fundamental increase in daily comfort. The house just feels better, more stable, and more protected from the elements.
- A Quiet Revolution
I never realized how much noise from the outside world was filtering into my home until it stopped. We live on a moderately busy street, and the sounds of traffic, neighbors’ lawnmowers, and barking dogs were just part of the background noise of our lives.
The new Feldco windows have created a serene oasis. The double-pane construction and the quality seals do an incredible job of dampening exterior noise. The first time a loud truck went by after the new windows were in, I braced for the usual rattle and roar, but it was just a faint, distant hum.
It’s a quality-of-life improvement you might not even think about when you’re shopping for windows, but it has made a huge difference in how peaceful our home feels. It’s easier to concentrate when working from home, and sleeping has become more restful.
- Smooth Operation and Low Maintenance
Let’s talk about function. My old windows were a workout to open and close. They would stick, jam, and sometimes refuse to lock properly. The Feldco vinyl windows are a dream to operate. They glide smoothly and lock securely with a satisfying click.
The tilt-in feature for cleaning is an absolute game-changer. No more climbing ladders outside or precariously balancing to clean the exterior of the second-story windows. I can now clean both sides from the safety and comfort of the inside of my house in a fraction of the time.
The vinyl frames themselves are incredibly easy to care for. A simple wipe-down with soap and water is all they need to look brand new. There’s no scraping, no painting, no staining.
This “set it and forget it” aspect is a massive plus for any homeowner who would rather spend their weekends enjoying their home than working on it.
The Not-So-Perfect Aspects of Feldco Windows
No product or company is perfect, and it’s important to go into a major purchase with your eyes wide open. While I am overwhelmingly happy with my decision, there were a couple of areas where the experience could have been smoother. It’s only fair to share the complete picture.
- The Waiting Game

From the day I signed the contract to the day of installation, there was a significant waiting period.
The initial estimate was 8-10 weeks, but it ended up being closer to 14 weeks.
This was primarily due to supply chain issues affecting the entire industry at the time, which the company was upfront about.
However, the communication during this waiting period could have been more proactive.
I found myself having to call for updates rather than receiving them automatically.
While every representative I spoke to was friendly and helpful, a bi-weekly email update, even if it was just to say “things are still on track for your revised date,” would have gone a long way in managing expectations and reducing a bit of anxiety.
For anyone considering Feldco, my advice is to be prepared for a potentially long lead time and be ready to take the initiative on communication.
- Installation Day Hiccups
The installation crew was fantastic—professional, skilled, and incredibly efficient. They laid down tarps, worked cleanly, and did a phenomenal job with the windows themselves. The minor issue arose with the cleanup of the exterior.
While the inside of my house was left spotless, there were some small bits of debris left in the flowerbeds below the windows—scraps of old caulking, a few screws, and bits of old wood frames.
It wasn’t a major mess by any means, and it only took me about 15 minutes to clean up myself. However, for a service at this price point, you expect a pristine finish both inside and out. It felt like a small oversight at the very end of an otherwise excellent process.
Keeping Your Feldco Windows In Top Shape
One of the main reasons I chose vinyl windows was for their reputation for being low maintenance. And they are! But “low maintenance” doesn’t mean “no maintenance.” To ensure your windows last for decades and continue to perform at their peak, a little bit of regular care goes a very long way.
I’ve developed a simple routine that keeps my Feldco windows looking and functioning as if they were installed yesterday. Taking these steps will protect your investment and guarantee you get the maximum benefit in terms of energy efficiency and operation.
- The Seasonal Cleaning Routine

I recommend giving your windows a good cleaning at least twice a year, typically in the spring and fall.
For the vinyl frames, sills, and sashes, you don’t need any harsh chemical cleaners.
In fact, you should avoid them as they can damage the vinyl’s finish.
A simple solution of mild soap (like dish soap) and warm water is perfect.
Use a soft cloth or sponge to wipe down all the vinyl surfaces. For stubborn spots, a soft-bristle brush can be helpful, but avoid anything abrasive like steel wool or scouring pads.
For the glass, this is where the tilt-in feature is your best friend. Tilt the sash inwards, and you can comfortably clean both the interior and exterior panes from inside your home. I prefer using a vinegar-and-water solution (about one part vinegar to ten parts water) in a spray bottle, which is effective and streak-free.
Squeegees work wonders for a professional-looking finish. Wiping down the glass on a cloudy day is a pro-tip; direct sunlight can cause the cleaner to dry too quickly, leaving streaks behind.
- Hardware and Track Check-up
This is a crucial step that many people overlook. The moving parts of your windows need a little attention to keep them operating smoothly. As part of your seasonal cleaning, take a vacuum with a brush attachment and clean out the window tracks.
Dust, dirt, pet hair, and insects can accumulate in there and hinder the window’s movement over time. After vacuuming, wipe the tracks clean with your damp cloth.
Next, inspect the hardware. Check the locks and keepers to ensure they engage properly and securely. Open and close the window a few times to feel its movement. If it feels a bit stiff or sounds gritty, it’s time for some lubricant.
It’s critical to use the right kind. Do not use oil-based lubricants like WD-40, as they can attract dirt and gum up the works. Instead, use a high-quality, 100% silicone spray. A very light application in the tracks and on the weatherstripping is all you need. Wipe away any excess with a clean, dry cloth.
This simple step will make a world of difference in the window’s smooth operation and will extend the life of the moving parts.
- Weatherstripping and Caulking Inspection
The seals around your windows are your primary defense against drafts and water intrusion. Once a year, do a close visual inspection of the weatherstripping around the sashes. Look for any areas that are cracked, brittle, or peeling away.
In my experience, the weatherstripping Feldco uses is very durable, but it’s always good practice to check. Also, inspect the caulk seam on the exterior of the house where the window frame meets the siding.
Look for any gaps, cracks, or areas where the caulk is pulling away. A tight seal here is essential. If you find any issues, re-caulking is a relatively simple DIY job that can prevent major problems like water damage down the line.
How Feldco Stacks Up: A Comparison
Choosing a window brand can feel overwhelming because there are so many options. Before I settled on Feldco, I got quotes and did my homework on several other well-regarded companies.
Here’s my analytical breakdown of how Feldco compares to some of the other major players I considered, based on my research and consultations.
- Feldco Vs. Wincore Windows

When I looked at Wincore, the first thing I noticed was the quality of their vinyl and their construction.
They produce a very solid, well-regarded window.
In a head-to-head comparison of just the window units themselves, the quality is quite similar to Feldco.
Both offer robust vinyl frames, energy-efficient glass packages, and good warranties.
Where the two diverge, in my opinion, is the business model. Wincore primarily manufactures windows and sells them through a network of independent distributors and contractors.
Feldco, on the other hand, manages the entire process—they sell, service, and install their own product. For me, this was the deciding factor. With Feldco, there’s one point of contact and one company responsible for the entire job.
If there’s an issue with the installation, I call Feldco. If there’s a warranty claim on the window itself, I call Feldco. With a Wincore window installed by a third-party contractor, you could potentially run into a situation where the installer blames the manufacturer, and the manufacturer blames the installer.
I wanted that single-source accountability, which made Feldco the more appealing choice for my peace of mind.
- Feldco Vs. Marvin Elevate Windows

This comparison is really about materials and budget.
The Marvin Elevate collection is a beautiful product line that features a fiberglass exterior and a wood interior.
There’s no denying the aesthetic appeal.
The strength and durability of the Ultrex fiberglass exterior are top-of-the-line, and the real wood interior offers a classic, warm look that vinyl simply can’t replicate. However, this premium construction comes at a significantly higher price point.
When I got a quote for Marvin Elevate windows, it was nearly double the cost of my Feldco quote for the same number of windows. For me, the decision came down to value and practicality.
While I admired the Marvin windows, I couldn’t justify the immense cost difference. The Feldco vinyl windows provided 90% of the performance benefits (energy efficiency, ease of operation) for about 50% of the cost.
If budget is not a primary concern and you desire the specific look of a wood interior, Marvin Elevate is a fantastic option. But for the best balance of performance and price, Feldco held the clear advantage.
- Feldco Vs. NEWPRO Windows

NEWPRO was an interesting competitor, particularly because their business model is very similar to Feldco’s.
They are a full-service replacement company that handles everything from the sale to the installation, focusing on a specific geographic region (in their case, New England).
The products themselves are also comparable, with a focus on durable, energy-efficient composite and vinyl windows designed for the local climate. The main differentiator I found was in the product specifics and the sales approach.
NEWPRO often highlights their composite “Celuca” material, which they position as superior to standard vinyl. My research suggested it’s a very high-quality cellular PVC material, but whether the performance difference justifies the potential price increase over Feldco’s high-grade vinyl is debatable.
The sales consultation with NEWPRO felt a bit more high-pressure and scripted compared to my experience with the Feldco representative, who felt more like a consultant. Ultimately, since Feldco has a massive presence and long-standing reputation specifically in the Midwest, they felt like the more specialized choice for my home’s needs here in Dhaka.
If I were in Boston, NEWPRO would have been a much stronger contender. It really highlighted the importance of choosing a company that understands your regional climate.
- Feldco Vs. Pella Impervia Windows

Pella is a household name, and their Impervia line is their fiberglass offering.
Similar to Marvin Elevate, Pella Impervia windows are made from a proprietary fiberglass composite that is incredibly strong, durable, and resistant to extreme temperatures.
Where Impervia differs from Elevate is that the interior is also fiberglass, giving it a clean, modern look rather than a traditional wood aesthetic.
In terms of performance, Pella Impervia windows are excellent.
They are highly energy-efficient and built to last. The comparison with Feldco once again came down to cost and material preference. The Pella Impervia quote was substantially higher than the Feldco vinyl quote.
While fiberglass is arguably a stronger and more rigid material than vinyl, the question you have to ask yourself is: is that extra strength necessary for your application?
For most residential homes, high-quality vinyl like that used by Feldco is more than adequate and provides exceptional thermal performance. The Impervia line is perhaps better suited for extreme climates or commercial applications where that extra rigidity is a key requirement.
For my home, the value proposition offered by Feldco’s vinyl windows was simply too strong to ignore.
Frequently Asked Questions (FAQ)
Yes, from my personal experience and extensive research, Feldco provides high-quality vinyl replacement windows that are very well-suited for Midwest climates. Their windows offer excellent energy efficiency through double-pane, argon-filled glass and Low-E coatings, which leads to tangible savings on heating and cooling bills. The construction is solid, the operation is smooth, and the maintenance is minimal. The key benefit is their full-service model, which means they handle the sale, service, and installation, providing a single point of accountability for the homeowner.
The cost of Feldco windows can vary significantly based on several factors, including the size and style of the window (e.g., double-hung, casement, picture), the glass package selected, and the complexity of the installation. Based on my experience and discussions with other homeowners, you can generally expect a professionally installed double-hung window to cost somewhere in the range of $700 to $1,200. A large picture window or a custom-shaped window would be more. The best way to get an accurate price is to have them provide a free, no-obligation in-home estimate.
Feldco windows are built to last for a long time. High-quality vinyl windows, when properly installed and maintained, can have a lifespan of 20 to 40 years. The vinyl frames will not rot, peel, or corrode, and the sealed glass units are designed to maintain their insulating properties for decades. Feldco also provides a lifetime limited warranty on their products and installation, which covers defects in materials and workmanship for as long as you own your home. This warranty adds a layer of confidence in the long-term durability of the investment.
This is a common question. Feldco does not manufacture the windows themselves. They have a long-standing partnership with a dedicated manufacturer that produces windows to Feldco’s exact specifications and quality standards. This allows Feldco to focus on what they do best: sales, customer service, and professional installation. By controlling the specifications and the entire customer-facing process, they ensure the final product installed in your home meets their criteria for performance and durability, particularly for the demands of the Midwestern climate.
My Final Verdict
After living with my new Feldco windows through blistering summers and frigid winters, I can confidently say I made the right choice. My home is quieter, more comfortable, and my energy bills are noticeably lower.
The investment has truly paid for itself, not just in dollars saved, but in quality of life. If you’re a homeowner in the Midwest looking for a window replacement solution that offers a fantastic balance of performance, value, and single-source accountability, I wholeheartedly recommend you get a quote from Feldco.
It’s an investment in your home’s comfort and future.
