"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."

"Ernesto responded quickly with a great price quote, and answered my questions. He was on time, and did careful work---even gently cleaning windows that had a UV-blocking vinyl film on them, at my request. My garage door windows also got included---what a difference! It's so great to have clean windows. I won't wait so long this time, before I call Nesto's again."

Windows questions, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Depending on the window style and your home's layout, you can install replacement windows from either the inside or the outside. Many installations are done from the inside because it allows for better access and weather protection, but some exterior installs are easier for certain types of siding or trim. The key is choosing the approach that gives you the best access to the frame while keeping the existing structure intact.

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

There are many signs to look out for that tell you it’s time to replace a double-hung window. If the window is drafty and inefficient, you may need a new window to block out air leaks and keep your utility bills from skyrocketing. Other signs that it’s time to replace a window include foggy glass, soft or broken window frames, or window sashes that won’t open or close easily.

If you live in a colder region, consider installing double- or triple-pane windows with low-E coatings, which can trap heat and keep your house warm. In hot areas, windows with reflective coatings and insulated frames help keep cooling costs down. If you experience a lot of extreme weather, then impact-resistant glass might be a worthwhile investment.
