Window Door Contractors FAQs, answered by experts

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.

Options include fiberglass, aluminum, and pet-resistant screens to suit different needs.

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Screen repair is always worthwhile, as tears and holes in your windows and door screens are unsightly and allow pests and debris into your home, rendering the screen useless. The faster you repair your screens, the faster you can open your windows and doors freely to let the fresh air in. Consider repairing multiple door and window screens during one appointment with a screen repair technician to make the investment and labor costs worth it.

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.
