"Don't need to know anything. The workmen will answer any questions eagerly. My project was not major (level my personal front sidewalk from the City's to my door) and only took 1 hour. These guys said they can work several projects a day, but some things like lifting and doing substantial things like driveways will take most of the day."

"I would 100% hire this company again. We were on a tight timeline and needed to have our garage service door replaced as part of selling our home. After several companies told us our timeline was unrealistic, I found Doors R Us. Our door was replaced in less than 24 hours after we called them. Professional and timely. Beautiful door and install only took about an hour."

"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.

"Working with them has been a breeze! We had them replace the last few windows we needed in a our recently purchased home. Each person we have spoke with has been knowledgeable! And we got a surprise thank you package in the mail with some amazing cookies!! The guys that came to do the install were kind, curious and efficient. Thy We have two kiddos and the guys joked around with them and were funny! The owner of the company (Rich) reached out to us the same day as the install to make sure we were satisfied with the experience and the work done. We have had a great experience all around and will reccomend them to anyone needing windows!! Thank you guys!"

Window Door Contractors FAQs, answered by experts

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.

Some local utilities or state programs offer rebates or tax incentives for energy-efficient upgrades, including solar screens. Make sure to check with your local energy provider or government agency to see if you qualify for any cost-saving programs. Federal tax credits may also be available for qualifying window and exterior home upgrades.

Some hardware or specialty window stores in your area may repair damaged screens, but it’s less time-consuming, more convenient, and potentially more affordable to hire a screen repair technician to come to your home to do the work on-site. The screen technician will have the tools and experience to get the work done the same day, and they can inspect other screens while there to help avoid repeat repair costs in the future.

While the telltale signs can vary for different types of screen doors, it may be time to learn how to install a screen door if you're noticing rotting, warping, or splintering accompanying the sagging. If you’re unsure whether to replace a sagging screen door, consult a local screen door pro for an inspection and final decision.

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.
