- LDLisa Dyke2 days ago5.0Everyone at window world has been so easy to work with. From scheduling all the way to installation I was very pleased with every aspect of my experience.
- HDHunter DionneJun 9, 20265.0I had Ethan Jones out for an inspection of my windows situation and gave me some bright ideas, good insight and very personable
- LBLaurel BurninghamJun 8, 20265.0Very knowledgeable and Ethan was great. Provided excellent information and a timely quote.
- VDVicki DeanJun 5, 20265.0Ethan came today to give me an estimate for vinyl window replacement. He is very knowledgeable and thorough , and took his time answering my questions. The product and the company is impressive.
- BWBrian WebbMay 18, 20261.0I filled out their online questionnaire for an appointment on a Windows quote. The first question was "What is your zip code". I received a call quickly, and Holly (very nice) proceeded to gather all my detailed information. She put me on hold while checking their availability for appointments. After several minute, she came back on and said they don't cover my zip code! Even their web site advertises Franklin County as where they cover. My zip code was the FIRST piece of information I gave them, and they had to go thru a detailed interview before figuring out they don't cover my area? I'm as close to southern Maine as you can get and still be in Franklin County!! I'm very glad they showed their incompetence before we wasted any more time. This is what I call a HUGE red flag as a company to avoid.....
Frequently Asked Questions About Window World of Southern Maine
What types of Payment methods & Financing do you offer?
We offer a variety of payment methods and financing options (subject to approved credit) depending on promotional period. Please contact us for more information regarding available options.
Will the replacement windows be installed from the inside or outside?
The majority of our replacement windows are installed from the outside. In some situations, it may be necessary to install from the inside. On the day of installation, your installation expert will assess your unique situation and explain the process that will best suit your home.
Do you install replacement windows year-round? If so, will I lose a lot of heat/cooling at the time of installation?
Window World installs replacement windows year-round. An average installation will take only one day. Our crews install one window at a time and are trained to do what they can to minimize heating/cooling loss. The energy savings from your new windows will recover any incremental energy costs incurred during their installation many times over during their lifetime.
How can I prepare my house for my replacement windows?
Please take down curtains, blinds, or any other window treatments. Security sensors should also be removed and turned off by your security company. Please provide our installation expert with a clear path to the window(s) being replaced by moving anything that may be in the way. It is also advisable to remove all wall decorations from the walls close to the windows as they may fall during removal or installation.
How long will it take to get my replacement windows? How much time should I allow for the installation?
Generally, replacement windows can be installed within 4-8 weeks from the date that the final measurements are taken. The type of window being installed and type being removed helps determine the amount of time needed to complete the job. On average each window takes about 30-60 minutes. Trim work and cleanup will require additional time to complete. An average job will take a single day.
What type of warranty is available for my windows?
Window World replacement windows come with an all-inclusive limited lifetime warranty. Contact us for more details.
What happens to my old windows?
After installing your new replacement windows we remove all old windows from your property and dispose of them properly. If you wish to keep your old windows or storm windows, please notify the installation crew as soon as they arrive for your installation.
What do I do if there is a problem with the windows?
Most of the issues encountered by our customers are easily corrected and don't necessarily mean that there is a problem with your window. As a first step, we recommend you visit the Support page of our website for troubleshooting tips and advice on correcting common issues.
