"If I could do minus on the stars I would give a -5 stars. This company is horrible and Skylar Jump is rude beyond beleif. He came out and did the bid for the job, and he told me what it would cost me. 1/2 down and the other 1/2 upon completion of the job. They installed new drywall but did not make it flush at the corners, leaving big gaps and putting in large gouges. He and his crew left garbage all over the yard, stole materials and left my house compromised and exposed to the elements. Also damaged some of my vintage furniture from the Hoquiam Castle. So no replacing those. He was calling me and his crew inappropriate names and telling me that I don't listen, constantly interrupting me and told me that my family member who is an expert in siding doesn't know anything and started dising people. Also will not give you a receipt for money paid and will not give you a break down of the job. Also, when picking up materials from Home Depot, he will charge materials for another job onto your account. Do not hire this company unless you want to punish yourself and lose your money."

Best of all, we stand behind our products and installation with one of the strongest warranties in the Seattle window replacement business.
"I could not be happier with the warranty work performed on our large dining room glider windows. Both Michael Donahue and Nick Baxter came up with a collaborative solution to remedy an uneven top reveal that spanned the length of our three piece large window. The original install had a few flaws that allowed both glider windows to detach fully from the top if opened due to not shimming the top window edge correctly which resulted in crowning of the whole top part of the 3 piece window. Mike and Nick came out and helped us decide on a solution that would make my wife and I happy. It took Mike and Nick a half day to redo the window. At the end I was completely satisfied as I am sure my wife will be when she comes home tonight to see the work performed. Renewal by Anderson is a top notch company that stands behind their warranty and promise and commitment to their customers. Thank you Mike and Nick for your expert craftsmanship and dedication to "make it right". Your attention to detail, cleanup at job completion, and making sure myself as a customer are happy with the final results before leaving is why I will highly recommend Renewal by Anderson to my friends and family who are in the market for Window replacement."

Washington Energy Services has been helping homeowners throughout Western Washington save money and live more comfortably since 1957. As one of the largest home improvement companies in the Seattle-Tacoma area, we are able to provide you with top-quality products and services, installed by our professional craftsmen. Our free in-home estimates ensure you get the right product for your home. We'll be with you through all aspects of your project from the purchase decision, expert installation, quality maintenance and service, and even warranty work should you need it. We assist with permits and rebates, too. Give Washington Energy Services a call today to learn more or to schedule your service.
"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

Modernized Exteriors is Washington’s Best Decking ,Siding, Windows, and roofing Residential contractor. We specialize in quality and customer service and we take pride in every job we do.
"Modernized Exteriors did a fantastic job with my deck reconstruction, gazebo rebuild, and installation of deck lighting! I selected M.E. from four contractors whom I had contacted. M.E. did two things right in that process. First, they did a phone consultation in order to give a ballpark estimate for my deck. They wanted to do a phone consult before coming out, because potential customers may drop their idea once they hear how expensive a project is going to be. M.E. does not send salespeople out to give estimates; the owners come out themselves. They were guarding their time, and I was impressed by that. The second thing they did right in the bid process was they were the only contractor to show me photos of their previous work. There are some outstanding examples that you can see on their website. I accepted M.E.’s bid, paid a 1/3 deposit, and given a schedule estimate for 6 to 8 weeks. Because of snowy weather in the Seattle area in late December/early January, my project did not actually begin until 10 weeks after my deposit. My project took about two weeks. Homes here in the Wallingford neighborhood of Seattle are a tight fit – as I put it – and I was a bit impacted by the need for a dumpster in my driveway (for old deck removal – my garage was inaccessible), and the need for a porta-potty for the crew on my curb strip. The inconveniences were well worth it, as my new deck looks spectacular! I only gave Modernized Exteriors four stars because I wanted you to read this review. As my project was underway, the crew was identifying additional work items that they deemed necessary in order to do the project correctly. For example, my old deck had a platform for my hot tub, and a wooden gazebo to cover it. We determined due to deterioration of the hot tub platform that the hot tub needed to be moved, and the platform rebuilt. This was an unforeseen need. As well, a considerable amount of soil and debris underneath the old deck needed to be removed, and the undergirding frame rebuilt. Perhaps naively, I was verbally assenting to these additional work items without inquiring about additional cost. Neither was this information volunteered by the contractor. The upshot is that my project went nearly 28% over the original estimate. By my opinion, exceeding a bid is a problem for one bit reason: The situation becomes indistinguishable from a contractor that deliberately low-balls an estimate in order to win business. I do not believe that went on here, because I could see that the additional work items were not foreseeable when the project was bid. All told, I would have agreed to the additional work even if the original bid had been updated. I value a job done right, and I have every expectation that my deck will last, and be beautiful for decades. The reader will have to decide whether the amount of surprise billing at the conclusion of the project was more the contractor’s fault for not updating the estimate, or mine for not asking about it. Congrats again to Modernized Exteriors for a job well done, and I do definitely recommend their services!"

"How did it go? Excellent! Jamie, the owner, was quick to respond to any and all inquires. Easy to reach, easy to get a hold of, both by e-mail and text. His team chief, Bob, clearly had years of experience! They were scheduled for 9 am and at 9 am, I looked outside to see the truck parked outside! Bob's experience came in handy when there were issues getting my sliding glass door into place, due to my residence being roughly 50 years old; which still had the the original, single pane, metal frame windows & slider door. If there were any issues with the same old type of windows which were replaced, I didn't know it because everything went so smoothly. Bob knew exactly how to quickly fix any issues, and his entire crew ran like a well oiled machine. The crew were extremely efficient. plus they went above and beyond; making sure the window glass and frames were cleaned and they vacuumed up the little bits of debris created when taking out the old metal framed windows and they took the old windows/door with them when they left for safe disposal. All the while never complaining about the pouring down rain! I would highly recommend this company, in short, for the excellent install , clean up and very fair pricing."

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
