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 and doors NO NO NO!!! Siding yes. CSR Colorado Siding Repair / Bellwether Homes did a full upgrade/renovation of our exterior. They did a great job on the HardiBoard siding but a horrible job on installing the doors. Gaps underneath the door, could see light coming thru and cold wind blowing thru. I have them come and "fix it" but did a lousy job and I ended up repairing it myself. They installed our windows OK but used the wrong color interior trim. I paid for TRIPLE PANE windows but they installed double pane windows with an add on non sealed window panel meant for an internal blind setup. Not really triple pane as quoted."

Window Door Contractors questions, answered by experts

You might be able to turn a normal door into a fire-rated door, but you’re better off purchasing one that meets all NFPA 80 standards. If you want to DIY a normal door into a fire door, you’ll need a self-adhesive intumescent seal, metal hinges, fire-resistant glazing, and a self-closing device, but you’re always better off buying a certified fire door.

A fire door can cost anywhere from $400 to $1,350 to purchase and have installed. The cost comes from the price of the door, which can be anywhere from $400 to $900 or more, and the cost of labor, which should be contracted out considering that fire doors are a safety measure. Most contractors will take between two and four hours to install one door.

Yes, you can clean door hinges with vinegar. The cleaner your door hinges are, the less likely they are to cause that annoying squeaking sound. Simply fill a container with equal parts water and vinegar, dip a microfiber cloth in the mixture, and use it to clean the hinges. You can do this while the hinges are connected or remove them, and wash them piece by piece.

Permits are required when carrying out any structural work, so in most cases, you will need a building permit to cut through a concrete block wall to install a door. If you have specific questions about your project or need to obtain a permit, contact your municipal building department or ask your contractor for advice.

If you’re installing a pocket door into an existing door opening, the new space will need to be twice the width of the existing door, plus an inch. You'll need to double that number if you’re adding dual pocket doors.
