After decades in business, we’ve gotten pretty good at anticipating homeowners’ questions about replacement windows. And of course you have questions—a window project is not something you do every day. The team at Big L Windows and Doors can help you assess your needs and determine whether to repair or replace.

It depends on how the window was glazed. If is has removeable stops, we can replace just the glass. If not, you may have to replace the entire sash. Sometimes the best solution can be to replace the window entirely. Someone from Big L can assess the damage.

First, try cleaning it as well as you can, getting in the crevices. The problem can be dirt and grime or a lack of maintenance. Usually, if it’s not moving at all, it’s likely a balance issue. If a lock or hardware such as a crank is not functioning, ask us if you can get a replacement part.

IThe sealant or caulking around your window is probably faulty. The repair could be as easy as adding new weatherstripping or caulking. If it’s a larger functional issue, you’ll need to replace the window.

Fog means there’s condensation. If it’s on the interior, increasing ventilation and lowering the humidity in your house can help. If the fog is in between panes of insulated glass, this indicates a glass seal failure. We can help you assess whether the panes can be replaced or you need a whole new window.

Not necessarily. First, consider that new, energy-efficient windows will save you money on your energy bills. And also think about what your time is worth to you. If you’re spending a lot of time on upkeep, cleaning, fixing jammed windows, repainting, or searching for discontinued spare parts for your older windows, you may eventually feel like the hassle is not worth it. But that call is up to you.

According to, replacing inefficient windows and doors with ENERGY STAR® certified products can reduce energy bills by an average of 12%. Here in the north, the average estimated savings when replacing single-pane windows with ENERGY STAR qualified windows is 22%, or $366 annually.

Casement or awning windows typically work well above sinks or places where you can only reach the bottom of the window.
