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.

Bell Wether Homes is a James Hardie Elite Preferred Contractor and 2024 winner of James Hardie's prestigious President's Club award, Pella Platinum Elite Certified Contractor and GuildQuality's prestigious GuildMaster award. We are your trusted guide for siding and window and replacement in the Denver area. Call today for a free estimate!

"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."

Windows questions, answered by experts

Bifold windows work by using a track that allows panels to slide to the side and "stack" so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you’d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they’re open.

To tell if a window is single or double-pane, focus on the edge. Double-pane windows have two glass layers separated by a spacer, which you can usually see around the edges. For single-pane windows, it’s just one sheet of glass. Another easy trick: shine a light at the window—single-pane glass reflects once, while double-pane glass reflects twice. Lastly, if you feel both sides of the glass on a cold day, double-paned windows will feel warmer because of the insulating gap between the panes.

Impact windows are absolutely worth the money if you live in an area prone to hurricanes. Though expensive, impact windows are built to withstand hurricane winds up to 200 mph and theoretically won’t break even if flying debris, such as mailboxes and lawn chairs, is smacked against the glass. A single broken window during a hurricane can destabilize the pressure inside your home, which can cause walls and the roof to collapse.

Impact windows are a type of window made with impact-resistant glass, designed specifically for hurricanes. The glass, treated with ethylene-vinyl, can withstand winds up to 200 mph, as well as flying debris. Brands sometimes test their impact windows with large missile impact tests.

Impact windows may be required in some places. For instance, the Florida Building Code requires homes to have impact-resistant windows if they live within a mile of the coast where wind speeds can reach 110 mph or more.

Yes, most manufacturers and contractors offer warranties for materials and labor. Confirm terms before purchasing.
