"The owner, Ben, did an outstanding job cleaning our residential windows (his company also does commercial window cleaning). To date we have used him twice. Sea-Thru Window Cleaning communicates very well with their customers - before, during and after. The result is appointments are kept and reminders for future cleanings are provided. I highly recommend Sea-Thru Window Cleaning - you will be amazed of the results."

Windows FAQs, answered by experts

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Consider adding sash locks to your windows to fix drafty windows if you don't currently have any. Sash locks in double-hung and single-hung windows help to create a tight seal when windows are shut.

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.

DIY is possible with the proper tools. Professional installation ensures a proper seal and energy efficiency.
