"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

"April 2021 We bought a house last fall and spent our first winter in it. During this time, we could clearly see and feel how uninsulated our windows were. Some original to the build of the house. I would be sitting at my desk working and see my curtains move and constantly feel the cold air on my fingers. It was a no brainer this was going to be our first major home improvement/project for our new house. We talked to two different companies and decided to go with C. Michael Exteriors for several reasons. Our salesperson Gary Langdon did a wonderful job explaining the process of how the windows were manufactured and showing us the very different factors of these windows from other companies. The multiple layers of insulating are a big factor for us. There are a several choices on colour, grides and type of style window you are looking for. We needed to replace seven windows. Two larger windows, converting one from a bay to regular, two basement, and three â normalâ room size. Each window is made to specifically to fit your needs and made here in the USA. Gary assured us the ease of the project from the skilled workers coming to put in the windows. This was a big concern of ours. We wanted to make sure everything was picked up and clean. Gary assured us the workers are very professional and will go through all the workings of the windows with us once completed. He was not wrong! We got a call saying our windows were ready and could they come that week (a few weeks earlier than estimated ). Chance and his crew showed up right on time that day and were all very professional and courteous. Each worker that came had a specific job on each window and this made the process go so fast and smooth. You can tell they have been doing this together a long time. It was flawless and like a â well-oiled machineâ . They were completed with in a few hours. Not days or a whole day, a few hours! The professionalism from Gary and all the skilled workers is definitely a reason to do business with C. Michael Exteriors. We highly recommend for any project that they can accommodate. Thank you for making our first home improvement project a successful one!"

I’m a one-person cleaning service, and my focus is simple: quality you can see and feel. Some competitors may be cheaper or have been around longer, but I never cut corners. Every home gets detailed, careful attention so it’s truly clean, not just surface-level tidy.\n\nBecause it’s just me, you’ll know exactly who is coming into your home, and I stand behind every job I do. I’m not finished until you’re completely satisfied with the results.\n\nIf you’re looking for a reliable house cleaner who treats your home or business with respect, I’d be happy to help.

Windows FAQs, answered by experts

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Look for stickers at the top or inside of the frame, like in the tracks when the window is open. Some brands also stamp their name onto the frame itself or place it between the panes of glass, although this is less common. If you can’t find the info on the window itself, consider asking your neighbors or HOA.

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

Impact windows are a type of window made with impact-resistant glass, designed specifically for hurricanes. The glass, treated with ethylene-vinyl, can withstand winds up to 200 mph, as well as flying debris. Brands sometimes test their impact windows with large missile impact tests.

Impact windows may be required in some places. For instance, the Florida Building Code requires homes to have impact-resistant windows if they live within a mile of the coast where wind speeds can reach 110 mph or more.
