Common Issues with Windows


Despite regular maintenance, windows can be subject to various problems that may necessitate costly repairs. Some frequent issues include:

  • Energy Efficiency: Older windows can leak air, causing your heating and cooling system to work harder to maintain a comfortable temperature in your home. Replacing your windows with newer, energy-efficient models can help reduce your energy bills and make your home more comfortable year-round.

  • Aesthetic Appeal: New windows can significantly enhance the curb appeal of your home. If your current windows are outdated or don't match your home's style, replacement windows can give your house a fresh, updated look.

  • Noise Reduction: If you live near a busy street or noisy area, replacing your windows with double- or triple-pane glass can help reduce noise pollution, creating a more peaceful and quiet indoor environment.

  • Improved Home Value: Replacement windows can increase your home's resale value. This can be particularly advantageous if you're considering selling your house in the future.

  • Safety and Security: Newer windows often come with better-locking mechanisms, providing an additional layer of security for your home. Also, certain types of glass can be used in windows to provide a barrier against break-ins. In case of emergency, new windows are often easier to open, providing a safer escape route.​

“I have had these guys to my house on several occasions for different jobs, and they're always fantastic. They are siding specialists but also fantastic general contractors. They can handle basic to moderate work with plumbing and electrical, along with any demo and construction needs you have. This means they don't contract out on most jobs and don't have to drive the price way up. They're good at what they do, they always offer a price that's hard to match. They're humble and kind, great with my daughter. They respond quickly to texts and are often able to schedule work in less than a week. I couldn't recommend them more.”
