"Green Valley has helped me on 3 roofs and window wrap - so far. Scott came out and gave me a bid and I could tell he knew what he was talking about. He gave me a great price, got me on the schedule right away, and did an excellent job. The crew worked fast and left the job site very clean! Because of Maria, Scott, and the crew, I will always call Green Valley for my future projects."

"I bought an Anglie's List deal to have one room painted for $99.  It turned out that the deal included only the walls, not the ceiling and trim although that was not mentioned in the ad for the deal.  When I pointed that out to AOM, they agreed to include the trim.   They also agreed to paint an exterior door at no additional cost.  I paid extra for them to paint the ceiling for which they supplied the paint.  I had consulted with them prior to 10/2 about the other paint, which I had purchased in advance.  The two men who did the work were prompt and meticulous.  There was a slight problem with the finish on the door which they corrected a few days later.

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

Window Door Contractors FAQs, answered by experts

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

While sometimes used interchangeably, screen doors and storm doors have key differences. Screen doors are simple structures, typically composed of just a frame and a screen, designed to keep out bugs while allowing air circulation. In contrast, storm doors are heavier and more complex, built to protect your home's main entry door from weather and intruders. They usually feature an aluminum frame with interchangeable tempered glass and screen panels, allowing you to switch between ventilation and insulation. A storm door offers more protection and versatility but generally costs more than a basic screen door.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.
