"Brandon R and Ryan P did a fantastic job of installing my new windows. The instillation was changeling due to the age of the cabin and the custom window shapes to deal with. They were professional, efficient, courteous and were able to answer all the questions I had about the new windows. Feeling very happy and very well served."

"Sean and one other person came out and were very efficient in measuring all the windows.  I believe they were in and out under 20 minutes, which worked great for me.  I think they would have been great to use, but I got the impression they were very backlogged in work (which is a good thing).  I chose another company, but felt that 1st Class Glass would have done an excellent job.

"They were excellent. They did a professional job and our windows turned out beautiful. Ricky, Joel, and Emilio were friendly, and did an excellent job. They cleaned up every day and got the job done in a timely manner. I would highly recommend Lake Washington Windows and doors."

Windows FAQs, answered by experts

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.

No, it’s not normal for windows to rattle in the wind. If they do, it may signal that there’s a larger problem at play. Common reasons that windows rattle in the wind are because the glass isn’t secure enough, the frame is loose, or the wood is rotting. In any of these cases, you should identify the problem and take steps to fix it.

No, windows cannot be made 100% soundproof. Even the most advanced setups still allow some sound to pass through because windows are designed to let in light and are not completely sealed from the outside. While you cannot achieve complete silence, significant noise reduction is possible, with some noise-reduction windows blocking up to 95% of outside noise.

The goal is to minimize air gaps, add mass, and reduce vibration. To block out as much noise as possible, consider hiring a professional to install new double-pane, triple-pane, or laminated windows. You can further enhance soundproofing with airtight seals, glass inserts, shutters, or sound-dampening curtains. With the right upgrades, you can block out traffic, neighbors, and other city noise to a much quieter level.

Wood windows are often worth the cost because they add more to curb appeal and your home value than more affordable options like vinyl and aluminum. Wood windows also offer better insulation than vinyl and aluminum windows, and they can last about twice as long. As such, they’re more expensive up front but offer greater value and a higher ROI.

Bay windows are supported by braces and industrial strength cables, often at the top of the window but sometimes at the bottom. The bay window may need buttress supports if installed on the second floor. Wood screws on the interior also hold the bay window in place. Bay windows are heavy and need proper support to prevent sagging and wall damage. You need to ensure that the support system can hold the weight of the window and the roof cab over the window.
