"We just needed the pane in one window replaced. They came to look at it the same day I called. He measured and ordered the window in less than 10 mins. As he said, 10 days later the window pane arrived. They came and installed the window that day in less than half an hour. The service was great, timely and affordable. I will definitely remember them for any future window replacements."

Windows questions, answered by experts

Your new windows may let in more noise than your old windows because they are not the right size or they were installed improperly. Improper installation, or choosing windows that are too small for the opening, can create gaps around the window that let in noise.

Another factor could be the STC and OITC ratings. If your new windows have lower ratings than your old windows, this means they have lower performance when it comes to dampening noise from the outdoors.

Whether or not it's worth it to install double-hung windows depends on several key factors. First, double-hung windows cost more than single-hung windows, so if you’re looking to lower costs, you might find it more worthwhile to choose single-hung windows. If you want the lowest maintenance requirements, though, double-hung windows are easier to clean.

Double-hung windows also offer better ventilation, making them a good option for bathrooms and kitchens. Single-hung windows have better energy efficiency than double-hung windows because they have only one moving part.

If your window well fills with water, first remove the water as soon as weather conditions allow, using a pump or wet/dry vacuum. If water has seeped into your basement, you may need to call a professional to assess the damage. Once the water has been pumped out of the well, check the drainage at the bottom of the well and clear out any blockages.

Hot water removes grime more efficiently than cold water and evaporates more quickly so that your windows will dry faster. However, you may want to use cold water instead if your windowsill paint is chipping or peeling because heat can worsen this condition.

Impact windows can last between 10 and 40 years, depending on how much wear and tear they receive. This is roughly within the range for standard windows; standard windows tend to last between 15 and 50 years. You can extend your windows’ lifespans by performing regular maintenance on them and ensuring they are installed correctly.
