Our company does retrofit window replacement. We have been in business since 1990.We have a 5 star rating and thousands of satisfied customers. NO SALESMEN! You'll deal directly with me the owner. You'll get a better product for less money. With windows it's all about heat loss and they measure that with what they call a U-Factor, the lower the number the better. Being a PUD approved contractor they require a U-Factor of .30. We can get that number down to a .21 for open windows and .18 for non opening windows. A third better but does not cost a third more. And if you live where there is a lot of noise it will almost eliminate it coming through the windows!
"Mike Smith is a very nice and with rich experience guy. He gave me a lot of good advice. His workers worked professionally and cleaned up all the work areas. I am very satisfied with the job. And I will refer him to my friends."

"Everything from end-to-end was professional, patient and detailed. We had lots of time with sales and design to see our options. They guided us through decisions we didn’t even know we’d have to make. The whole house was immediately warmer and the installation was so smooth. (At least from our side. I hope the installers felt the same.) The installation team told us each day what they would be working on tomorrow and worked around a couple of tight and high areas with no issues. They took extra steps to protect the surrounding areas and provided great information about how it was going. They took time to save some special millwork around the front door on the inside that we weren’t sure could be saved. It looks great. Finally, the Milgard windows we chose are so crystal clear, it feels like I’ve moved to a different yard. So grateful for everything Lake Washington Windows and Doors provided for us. Thanks to John, Mike, Chris, Josh, Joel, (and that other guy that showed up. LOL!) And Amy… thank you for being diligent and continually following up with us. Even when we didn’t get back to you right away. You were so polite."

Making an existing window bigger always requires some construction, but the extent varies by project. Vertical expansions involve less structural work because they often don't affect load-bearing elements. Even so, any enlargement requires removing siding or drywall, cutting framing members, and installing appropriate support. Non-load-bearing walls allow for simpler modifications, while load-bearing walls require proper headers and structural support. A consultation with a structural engineer is advisable before beginning any window enlargement project.
Building permits are required for window enlargement projects in most municipalities. Since enlarging windows involves structural modifications to your home's exterior walls, local building departments need to review and approve the plans. Permit costs range from $100 to $300, though projects requiring significant structural changes may incur permit fees of $500 or more. Additionally, homes in historic districts or those governed by HOAs may need special approvals. Always check local requirements before beginning work.
An average window enlargement project takes between five hours and three days to complete. Simple projects with minimal structural changes might be finished in five to ten hours, while more complex enlargements requiring significant structural modifications could take up to three days. Factors affecting the timeline include the window's location, wall construction, weather conditions, and the need for specialized materials. The process involves demolition, framing, window installation, and interior/exterior finishing work.
