Signs that you may need window installation or replacement include drafts, rising energy bills, difficulty opening or closing windows, visible damage, or condensation between panes. If your windows are 15–20 years old or older, they may also lack modern energy-efficiency features. During your consultation, Thermo-Seal will assess your current windows and help you determine the best solution based on performance, appearance, and cost.

We install a wide variety of energy-efficient window styles, including double hung, casement, sliding, bay, bow, garden, and picture windows. Each style is available in materials like vinyl, wood, or composite to suit your home’s architectural needs and personal preferences. Whether you’re looking for better airflow, larger views, or a custom look, we’ll help you choose the right window styles for your space.

Most standard window installation projects can be completed in a single day, especially if you're replacing multiple windows of standard sizes. However, the timeline can vary depending on the number of windows, type, and any custom specifications. Thermo-Seal’s experienced, in-house crews work efficiently and cleanly, ensuring your project is completed with minimal disruption.
