"It went extremely well. They kept us up to speed on their arrival times. Eduardo and KC were courteous, professional, and did a great job on our windows. And, they came in at the lower end of the estimate. I will hire Smart Window Cleaning again."

"American Home Renewal recently replaced 7 double hung windows in our home. We had 3 window replacement companies come to our home discuss the process and give us estimates. Chris from American Home Renewal was by far the most professional. He spent time with us, accurately described the entire installation process with us and exhibited willingness and patience to hear and understand what we were looking for in the new windows. The American Home Renewal contract was clear, concise and straight forward. The 3 day installation process was fluid and fairly quiet and we were able to work from home. It had a minimal impact on our lives. The crew cleaned up thoroughly every day and took time to make sure we knew how to tilt the windows for eventual cleaning etc. Keith, the Production Manager, checked in a few times during the 3 day installation period to ensure everything was progressing to our satisfaction. We could not be more pleased with American Home Renewal's level of professional service and care."

"Adam clearly explained my choices, with prices, for my door screen repair work. His work was excellent and his prices were reasonable. He arrived on time, with a text message just prior to his arrival, as agreed."

"Mr. Rick Pellhum, the General Manager, of "Northwest" Home Improvements, expertise, insight, and patient, courteous, professionalism and return inspection - with reviews and suggestions - were extensive and very helpful and useful in getting the non-tempered glass windows replaced and negotiating the same with the regrettable contractor we had used instead of Northwest.. Rick goes the extra mile in demonstrations of products and explanations of how things work and should be done. He takes his time and fully and objectively ticks all the boxes and covers all the bases. Once he has discussed a project proposal with you - you have been educated and really have a grasp of all the details. He fully engages you in sharing his knowledge and years of experience and the confidence that he has in his company's products, ethics, capabilities and workmanship. In hindsight now I can honestly say we should have gone with Northwest and I regret not having done so. Rick demonstrated the difference between the windows/product we ended up with, and the ones Northwest had proposed installing for us, by going out to his vehicle and bringing in an infrared lamp that when plugged in and held up to the window panes we have - versus the ones we could have had if we had contracted with Northwest Exteriors - clearly indicated an inferior product was installed by the party we went with. Rick was kind enough to outline remedial steps for me towards resolving the issues we were facing with the competitor we had gone with instead of Northwest. He gave me very sound advice. I highly recommend Rick and Northwest. In all of my dealings with him/them over the last year and to date they have always been responsible, punctual, professional, courteous and very thorough and reliable.

"Great experience. Found AMG doors and windows online and they reached out and were able to clearly and professionally explain the step by step process of measuring the door ordering and the installation process. They were hassle free and was able to give me and over the phone quote for my new French doors. The install only took them 4 hours and they keep the space clean and were very professional."

"Excellent! They did such a great job and at an outstanding price. I have so many windows in my house and they came in way below any other competitor. It's been a few years but the windows still look and work great! As a matter of fact, my next door neighbor recently hired them to replace all of their windows based on the job they did at my house."

"This company will do the job you asked for, and once they get started it will be done quickly and professionally. However, their communication leaves a lot to be desired. Our project got pushed back at least twice for a week at a time, throwing off our other projects. Again, the quality of their work is "A" level. Their timing and communication is a "C" at best."

Windows FAQs, answered by experts

Storm windows are placed outside of already-installed windows. Regular windows are installed into a frame, offering a barrier to the elements but no special protection. Storm windows add extra protection to regular windows, reduce noise, and improve insulation. Replacing a regular window involves a different process than installing a storm window. 

To find and hire a reputable contractor for an egress window installation, you should first research local professionals and then vet your top candidates. Start by searching for local contractors who specialize in this type of work, read their customer reviews, and examine their website and portfolio. Once you have a shortlist, contact them to ask key questions: Are you licensed and insured? What is your specific experience installing egress windows? Can you provide references from previous customers? Do you perform the work yourself or use subcontractors? What is the estimated project timeline and your current schedule? How do you handle payment?

Not every home needs window capping. Whether or not you need to cap your windows depends on your climate and window frame materials. Wooden windows should have window capping if moisture is a problem. Arid climates like the Southwest may not need window capping due to low rainfall and low humidity.

Windows provide light and a view of the outdoors without the inconveniences that the outside world can come with, like noise, rain, snow, and unpleasant scents. Vinyl windows also provide energy efficiency thanks to their insulating properties, keeping your home at its coziest temperature no matter what season it is. They’re also excellent noise dampeners, so your interior space can stay calm and quiet.

DIY is possible with the proper tools. Professional installation ensures a proper seal and energy efficiency.
