One question we get asked a lot is about window grids, should you have them or not?

In Colonial days, the production of glass window panes was limited to smaller panes that could be packaged and shipped by horse in a satchel or box. The glass panes were held into place with wood moldings, this way of building windows leads to provide a look that we now know as Colonial window grids also referred to as grilles or Muntins.

Grids are window strips made from vinyl, wood, aluminum or PVC, which divide a window glass into smaller panes which are called lites.

I am extremely happy with the services. The experience was simple Karoly the owner came out did the measurements. I worked with the office regarding scheduling. The office was responsive. The installer crew took care of my house and covered everything. The clean-up was spotless. The building inspector said installation exceeded the requirements. Karoly Windows and Door exceeded my families’ expectation. I recommend them for any door/window installation.

– Cora Hill

Karoly Windows & Doors recently installed hurricane impact rated windows & doors throughout our entire home. From estimate to installation, the experience was surprisingly stress free. Karoly & his office staff responded promptly to the inquiries we had. Tackling the entire replacement at once is a big investment & this Company recognizes and respects that. The install team was fantastic; they were like a well-oiled machine: highly efficient! They showed up on time, were hard working, professional, yet friendly. They did a beautiful job with the installation, and left the worksite clean afterwards. We love our new windows & doors! Would highly recommend Karoly Windows & Doors.

– Karen Ellington

From estimate to installation/inspection – this was a seamless process with Karoly & Co. Very happy with the windows and door selected in the upgrade to my home. After interviewing several companies, I would honestly say I highly recommend them – best quality and best pricing.

I love my new windows and doors. It makes the house feel warmer, while the outside temp is in the 30's. Plus, the outside noise has reduced, greatly. Karoly and team did a great job from the initial estimate visit, to the office communications, and then the installation team. All professional and knowledgeable. Everything went smoothly and very impressive to watch.
