"I would highly recommended WCV windows. The 2 man crew that installed 9 new vinyl windows including a sliding door did an excellent job in just a day! We were amazed by how their attention to detail gave us beautiful looking looking windows inside and out. Allso, we're staying much warmer and have much less outside noise coming in. A job well done in very friendly professional manner."

"We've now completed replacing all 18 windows in our home and could not be happier with the results. We're very impressed with the quality of our new Anderson windows, as well as the superb workmanship that Ryan P and Bama displayed installing them in our home. This was our third time working with Ryan P and Bama, and we can't say enough about the courtesy, care, and professionalism they brought to our home each time they came out. It was an absolute pleasure working with both of them."

"It was an excellent decision to have 10 windows replaced by Harley Exteriors. Our old drafty windows were replaced by beautiful new insulated windows. The crew was excellent and done within a few hours. Great communication throughout the experience and I would highly recommend Harley Exteriors if you are looking for new windows."

"The process from initial quote to final installation with Lake Washington Windows and Doors was all positive! Their team has been responsive and helpful throughout. On installation day, Andy, Taz, and David arrived on time and did an excellent job. They were friendly, professional, and efficient. They respected our space, us, and even our cats. We are so pleased with the finished product!"

"Tim Thompson is one of the best and most thorough people I’ve ever worked with. Not only did he get the project done to his high standards, but he didn’t leave until he checked everything out and made sure it was perfect. We have a 3 story house with a solarium and every window sparkled. Thank you, Tim."

Customers say: Super punctual

"During the last very heavy rain the rain gutter overflowed causing water to flow into the window well and then into the house causing flooding in a basement bedroom. I had several people come out to give an estimate to re-slope the gutters and discuss a back-up system in case the gutter over flowed again. Jack was great! He absolutely listened to all of my concerns and had ideas to fix both problems--the rain gutters and to fix the flow of the water as a back up in case the gutter overflowed in the future. he understood the consequences of these heavy rainstorms. The tenants were even impressed and sent a text to me saying, "you guy did an excelllent job." 
Since the job was completed we had another huge rainstorm and everything held--no problems. Jack is awesome!

"Had a great experience with Chris.he and his colleague installed three new windows (not replacements), including cutting new openings and redirecting gutters. They were always on time, worked cleanly, cleaned up thoroughly after the job, and offered a very fair price. Highly recommended! Thank you!"

Windows questions, answered by experts

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

The amount of time window lintels last is based on the environment they’re installed in and the material that’s installed. For example, a steel lintel installed in a temperate climate will always last longer than a wooden or brick lintel installed in an area with tons of rain, snow, and wind. No matter which material you choose or where you live, proper maintenance will ensure your lintels last as long as possible.

Steel windows are durable and last a long time, but not in all weather conditions. If you live near the ocean, these windows might not be the best choice, as the saltwater breeze can corrode the metal. Steel windows are also more expensive than other types of windows. However, with that high price point comes a sleek, distinctive design that many homeowners find appealing, especially for modern decor. You can also restore steel windows to get a longer lifespan from them, so they can last longer than vinyl, aluminum, and even wood.

Yes, window manufacturers and installers can mull together three windows—or even more—for a more impressive appearance that lets maximum natural light into your home. However, you may have constraints regarding the total size of the wall opening. Your installer can help you determine what size wall opening is safe based on the structural load. In most cases, you can install additional supports to span the opening, like a steel I-beam, but this drastically increases the installation cost.
