"Northwest Home Repair responded immediately when contacted about a water leak that I couldn't locate, but could hear. Two technicians worked to finally locate the leak (unfortunately it was in the crawl space under my house) and a third plumber made the repair. I was informed up front of all costs. The repair was completed within 5-6 hours of my call even though the responding plumbers were almost 60 miles from my location on Whidbey Island. I HIGHLY recommend Northwest Home Repair Solutions...they are five star professionals! Kit McCartney"

"We are senior homeowners who need help with odd maintenance and moving jobs. Jose contacted me immediately when I asked for a quote - some of the other contacts never got in touch. He came to our home that day to see what we needed and assess the need - and then he patiently waited two weeks to do it, rescheduled because we were ill. When we finally did meet, he did an excellent job in a very short time. We are already talking to him about another job. If you need someone with good skills and a great work ethic to help you with essential jobs you can no longer do, call Jose."

Windows FAQs, answered by experts

Common problems include broken latches, misaligned tracks, and worn seals. Regular inspection prevents major repairs.

Options include interior, exterior, and double-pane storm windows. Choose based on needs and preferences.

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

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.

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.
