"My computer (Windows XP) was running very slow and had become almost inoperable. It was taking a very long time to process anything, especially anything to do with the internet. IE was taking 100% of the cpu most of the time. Jim worked on my computer remotely for several days defragging, cleaning, anti-virus, malware, etc., but could not get it to perform anywhere near where it should. We decided that I needed a new computer. Jim built me a new computer (Windows 7 with racing stripes). The new system works very well and I am pleased with it. When Jim switched my files over from old to new, the Kodak Easy-Share program with my pictures did not get transferred. He has promised to make that transfer when he installs a new door covering the DVD reader which was broken upon setup. I will update this review when this occurs. I am very pleased with the new system and would do it all over again if a similar situation were present.

"Sales process was good, courteous and helpful. Installation instructions were easy to follow. Did have a small issue with one sensor which was easily solved with a call. Control panel is easy to use and well constructed. Phone app is the best part. Not a big fan of a 2 year contract and the monthly rate feels a little high, but definitely a decent system. I had emailed them a question pertaining installing on double hung windows and never received a reply, but other than that their phone support prior to that was good."

Windows FAQs, answered by experts

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Before purchasing, it’s good to weigh the pros and cons of vinyl windows. Vinyl windows offer several advantages over other types of windows. Vinyl windows are more affordable than most other window types, and they’re also very energy efficient. Vinyl windows are also low-maintenance, weather-resistant, and easy to install.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

No, not every window has movable sashes. Many fixed or stationary windows that were intended only to provide views and sunlight still have inoperable sashes that allow them to match the rest of the windows in a home. These are called sash-set fixed windows. They are created by glazing a window into a sash that is secured to a frame.
