"Nightshade was the 3rd company I had in to quote new motorized shades in my home. After seeing what they had to offer, it was an easy decision to go with them. They gave me a fair price, with shades that were perfect for what needed. They had many different options and walked me through what would work best in each room. The customer service was top notch. When it was time for installation, they came in and made sure to cover my floors and did a quick, neat job. I would recommend them to anyone looking for window coverings. A+++"

Window Treatments FAQs, answered by experts

Consider adding sash locks to your windows to fix drafty windows if you don't currently have any. Sash locks in double-hung and single-hung windows help to create a tight seal when windows are shut.

Options include interior, exterior, and double-pane storm windows. Choose based on needs and preferences.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

If your windows are drafty, fogging up between panes, or hard to open or close, it might be time for a replacement. Unexplained increases in your energy bills, rotting frames, broken seals, and noticeable noise from outside can also indicate it’s time for new windows. In addition, if you find yourself frequently needing to repair your windows, it’s probably more cost-effective in the long run to replace them.
