"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

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

Options include fiberglass, aluminum, and pet-resistant screens to suit different needs.

You can trim an overhead garage door screen to fit your garage door opening. This is a particularly helpful hack if you have an irregularly sized garage door opening but are still interested in installing a garage door screen to keep pests and debris out. Trim the garage door screen carefully to avoid unsightly edges or an uneven fit.

For most common repairs, a professional window repair service can fix a window in one to three hours. However, replacing window frames or repairing a large, multi-pane window will likely take longer to complete. For comparison, a window installation or repair professional should be able to replace up to 15 windows per day.

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.
