"We recently had a fantastic experience with Jim / OHI. They built us a beautiful new deck and installed a patio door, and the workmanship was excellent from start to finish. When we ran into unexpected building and zoning issues with the town, they were incredibly flexible and worked with us to adjust the project. Instead of the larger deck we originally planned, they created a stunning patio in that space, which turned out even better than we imagined. The crew was professional, reliable, and detail-oriented, and the results have transformed our backyard. We couldn’t be happier and highly recommend OHI to anyone considering a deck or patio project."

Windows questions, answered by experts

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

The biggest disadvantages of low-E windows have to do with cost and, depending on your personal taste, appearance. Low-E windows cost more than traditional windows—typically between $300 and $1,000 per window, plus installation costs. Though they can save you money in the long run, low-E windows have a hefty upfront price tag. Additionally, low-E windows have a slightly different look than traditional windows. While some people don’t notice it, others say the low-E coating gives windows a hazy look.

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.

You should caulk your windows about every five to 10 years. But you should make sure to inspect the windows every year, typically before winter, to look for gaps or signs of failing caulk, such as cracking or peeling. If the caulk is weak, you may need to remove and replace it before it's five years old.

There are several ways to keep your existing windows from letting in noise. You can install sound-dampening curtains or other window treatments that help deaden noise vibrations. Make sure any gaps around the window are sealed with acoustic caulk. Installing acrylic or plexiglass on the inside of windows still allows you to take in the outdoor views while also stifling sounds from coming in and out. 

If you try all of these steps and still have noise coming in, it might be time to install new windows.
