Outstanding at all levels. I had all my windows and doors replaced years ago and it was the best decision ever. This was not just because of the pricing and quality of their products and installation but their customer service and warranty are the best. Since the install there have been some minor issues and John or Jeanne always handled promptly and even shared tips and tricks which were great. Most recently there was an issue with the front door and it had to be replaced. I’ve had the pleasure of working with Darrin Kelly, Operations Manager on this. He went so far above and beyond to resolve this I can’t express how grateful I am. He even installed the new door himself. I’ve recommended Window World to so many and will continue to do so. Best company to work with. Highly recommend.

Kind, courteous, and high quality workmanships! I have gotten nearly all my windows replaced in my old house and some are challenging large sizes and wild shapes (trapezoid 😂) and they have exceeded my expectations each and every time. Their prices are reasonable and their technicians professional. I have a few more sliding doors and some more wild shapes (semi-circle) that will likely reach their lifetime in the coming years and plan to go with them for these replacements. Thank you for the great work!

Window world does consistently great work. Their products are top notch and the installers are excellent. We have purchased windows, a storm door and now sliders for our deck. We are very happy with them all and recommend window world to everyone.

This is our second time using Window World. We had them replace all of our windows a few years ago (and they even came back out when we noticed a scratch to replaced the full unit!) and now we just had them replace our front door, install a storm door, and replace our shutters. All have been great experiences, their prices are competitive with other local businesses, and we are thrilled with the end result.

Window World of Harford County installed our windows and back porch door in 2015. Recently we ordered a new door handle for the back porch door. As my husband was installing it we realized the lower closer bracket was bent which prevented the door from shutting properly and allowing the back door to be locked. I spoke to Linda and she scheduled Darrin to make a service call the following week. He arrived promptly at the scheduled time, replaced the bracket, made a minor adjustment to the door handle and checked that it was in perfect working order before he left.
I was reminded that Darrin had been to my home last year when I was having a difficult time opening the window above my sink. During that visit he reinstalled a screen on a casement window on our second floor. While he was on our roof he offered to clean the outside of that window. Since I appreciate clean windows. . . I was VERY grateful!
Frequently Asked Questions About Window World of Harford
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.
