"I had siding replaced and very displeased with the entire process. The crew did a poor job for what I paid and have already had to be back out here 3 times in a month to fix their mistakes. Crew cheif never checked the work to determine if the quality was up to the company standard. The crew left the property a mess with my belongings scattered around the yard. They had leftover pieces scattered as well. The craftsmanship and quality was aubpar for the price. No care for the property. Damaged driveway, roof, windows, and garden bed. Chalking already cracking. Large gaps in the siding. Siding already buckeling. Seams not together. Asked to speak to a manager or supervisor multiple times and still no response. I was promised certain tasks at point of sale that company will not follow up on. Over all this company treats their customers as money and gets in and out with little oversight or quality check. I am very displeased with the product I got for the money I paid. Will never recommend."

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

Windows questions, answered by experts

A garden window is about 16 inches to 24 inches deep. This extra space makes room for small potted plants, which is how the garden window, also called a greenhouse window, got its name. Because garden windows jut outward from the house, they need to be installed in a place where they won’t obstruct walkways.

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.

Whether or not you need permission to change the windows in your house depends on your local laws. If you’re enlarging an opening or installing a new window and need to make structural changes to the house, you’ll need a permit. In most locations, you won’t need permission if you’re just replacing a window with another window of the same size. The window installation company you work with will be able to help you navigate any planning permits you may need.

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.
