"It was amazing. Before the work, it was amazing how little rain it would take to cause standing water in the yard. After they completed, we got 2" of rain in one day and had no standing water anywhere in the area they worked."

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.
"Love our new Grand View Windows from Window Nation 17 Windows and 1 Sliding Glass Door We did quite a bit of research, explored a lot of companies and choose Window Nation for our project. And we are happy we did. The whole process from presentation to installation was easy and efficient. Reza arrived at our house on time for the presentation. He inspected and measured our windows and then launched into the presentation. Reza is knowledgeable about the Window Nation offering as well as the products offered by his competitors. As mentioned, I did some research and had an idea of the features that we wanted and what we should pay. Reza presented the Window Nation Grand View line, which meets our feature requirements, and after a bit of back-and-forth negotiation we settled on a price that was within our range and fair to us both. After signing, Reza described the next steps and set expectations. Overall, the presentation took only about an hour and was relatively painless, with no high-pressure tactics. Several days later, Mike came by to inspect our windows and confirm measurements for the build specifications. This took only about a half-hour. Mike answered some questions about the installation process and said that the windows and door could take up to 6 weeks to build. Imagine our surprise when we received a call a week later to schedule our installation. On installation day, the three-man team arrived on time. They introduced themselves and the team lead, Ted, described the process and then they got right to work. They tarped the paths to all the windows to protect the floors. They were very careful and respectful of our house. The entire team was friendly and polite and experienced and highly skilled. You could tell that they’d done this a time or two. The outside trim work is fantastic and the inside finish work is great. All 17 windows and the sliding door were installed in a single day. Ted went over the operation of the windows and door. The windows and door look and function great. We couldn’t be happier. If you are considering a window or door replacement project, we strongly recommend that you engage Window Nation. They will treat you right."

"We met with Ryan and Pete who were both extremely professional and knowledgeable. They met with my husband and I discuss new windows for the main floor of our single family home. We have a toddler and newborn and Ryan helped keep our toddler occupied and was very understanding and patient as we had to multitask in taking care of our kids while also discussing the window project. We were impressed by their warm, genuine approach which is very different from a typical salesperson trying to get you to go with their product. You could tell they truly believed in the company, the goals and values, and the product/services they provide. Due to personal reasons we weren’t able to invest in the project right now but we will 100% be contacting Ryan in the future and using Peak for all our future window/roofing needs. When you find a good, reliable company like Peak you want to make sure to spread the word and we will be recommending them to our family/friends/neighbors who need any projects done in their homes."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

FAQs for window service projects in Rockville, MD
If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
