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.

"Alex was our salesperson he did a great job of showing us what needed to be done regarding our project, (which was installing a new rear door). He was very understanding of our needs and wants. They were the first company who came out and we went with them without getting any estimates from any other companies. GREAT JOB."

"In 2014 we replaced 18 windows and were very happy with the windows and service from Weather Tight. At the time we did not replace 6 windows in the rear. The rear doesn't get hit with the sun and weathered better than other areas. Last fall we noticed some rot on the cedar siding below a picture window. Decided it was time to call Weather Tight. Once again Weather Tight exceeded our expectations. Ryan, our sales rep, made sure the windows would match the ones installed 9 years earlier and clearly explained to process and scheduled an installation date to accommodate us. The water damage below the window was much worse than expected. Chris S, Chris C, and Josh did an amazing job replacing all the damaged wood. We built our home 29 years ago. Our contract appeared to state that the O.S.B. would be covered with building paper or felt. IT WAS NOT. That is what caused the water damage. Weather Tight caulked, foamed and covered the new O.S.B. with Tyvek Home Wrap, and replaced the cedar shingles. They also did an exceptional job installing our new replacement windows. They look amazing inside and out. We highly recommend Weather Tight. The people and product are extraordinary."

WASCO Windows opened in Milwaukee in 1957 as Wisconsin Aluminum Supply Company, and was purchased by Dave Paulus in 1983. At that time, the company manufactured aluminum storm windows, siding and awnings. Under Paulus’ direction WASCO became the first company in this area to manufacture then-new vinyl replacement windows. Since 1983 the Paulus family has transformed WASCO into a company that leads the industry in manufacturing and installing highly energy efficient window products, engineered for Wisconsin’s unique climate.

Window Door Contractors questions, answered by experts

Sometimes, these two terms are used interchangeably, but they are separate parts of a door, and each serves a different function. The sill helps ensure the doorframe is secure, and the threshold helps protect the sill and direct water away from the door to prevent leaks.

Look at the door from the outside, or the key side. If the hinges are on the left side of the door, it’s a left-hand swing. If the hinges are on the right side of the door, it’s a right-hand swing. You can also think of it as which hand you would most likely use to open the door from the outside when considering whether it’s a right-hand vs. left-hand door.

To achieve the correct opening size for a 30-inch door, add 2 inches to the door width and 2 ½ inches to the door height. For example, if you have a 30-inch-wide door with an 80-inch height, then the rough opening would measure 32 inches wide by 82 1/2 inches high

To build a standard size, six-panel door yourself, you’ll need four 2-foot by 6-foot boards, one 2-foot by 8-foot or 2-foot by 10-foot board, and a sheet of 3/4-inch, paint-grade plywood. The 2-foot by 6-foot boards will serve as your stiles, top rail, and horizontal and vertical mullions, and the wider board will serve as the bottom rail, which is usually wider than the other horizontal pieces. The plywood will serve as the panels, but you’ll need around five 1-foot by 6-foot boards to make your own panels if you want to stain the door rather than paint it.

Most of the interior doors in your home are the same size. For example, most bedroom doors may be the same size. However, your closet doors might be the same size as each other but are a different size from the bedroom doors. You might also have bedroom closet doors that are a different size from hallway closet doors. It’s best to be safe and measure any door you want to replace.
