"The installers came on time and were totally professional, experienced and worked continuously until the job was done. The triple pane windows are fabulous because compared to our old two pane faulty windows, not only are they solid and beautiful with no wind blowing through, but also the nearby road noise is greatly reduced. We needed to use plastic film to insulate the old windows and when the wind blew the plastic would billow like sails! The new windows make our condo seem like a true home."

"In the middle of a bathroom remodel, I realized I couldn’t use the store bought bathtub glass door I had. My bathtub was cast iron and had a beveled edge. I contacted Guncay to make me a custom bathtub glass door. He promptly came over to give me an estimate and went over different options with me and their prices. Everything was done quickly and with great attention to detail. Beautiful work. Would hire him again in a heartbeat."

"Everything from first contact with the office staff to set up the appointment to when the installers left was a completely positive experience!
Office schedulers found us an evening appointment around our work schedules and were very friendly.
Al Vestro, our salesman, contacted us prior to arrival, and even showed up early once checking if we were available.  He carefully went over the options, and didn't try to "upsell" at all.  He explained that a higher sun-filtering glass was available, but generally not needed in New England.  Also mentioned the option of "divided lites" to go on the outside of the window to retain the original look of the sash bars, and advised if we had a historic home it would be required but since we had just a "normal" home, it would mean more difficult cleaning without a lot of real difference in look.  I appreciated his honesty in showing the options without the hype to sell the more expensive options.  He recommended the best option for our home and neighborhood.  Also, there was no pressure to sign the contract right then and there.  He provided the estimate at the time of the inspection and then left it up to us to decide and get back to them if we wanted to proceed.  He also explained the financing options with their financing company and we opted for the one year same as cash option so we didn't have to write a check for the deposit.  Much easier option! Al estimated 8-10 weeks between when we signed the contract and when the windows would be installed.  This put us at about a week or so after Thanksgiving.  Not ideal, but we wanted them in for the winter.
Once we signed the contract, David DiGiorgi called and set up the appointment to measure the windows.  My husband was home that day, and said he was very punctual, friendly and professional.   
David called earlier this week and said the windows were ready and set up a day for the installation - which was today.  Nov. 6th, at least  three weeks earlier than expected!  it couldn't have worked out better, considering we are having a warm spell with temps in the 70's today (New England, early November - go figure!)
 
We were told the installers would be at the house at 8:30.  The first truck arrived at 8:20 and all the installers were on site by 8:30.  We took care to move things away from the windows before they arrived so they could get right to work.  I did not take things off the walls because we were told we would not have to.  But they had to do some heavy deconstruction work to get the old windows out and the guys took the collectible plates off the dining room walls so they wouldn't fall and break.  I so appreciated that care and thoughfulness.
They started the actual work around 8:45 and were done installing all 9 windows by 1:00.  They cleaned up everything, and other than a little dirt on the kitchen counter, and of course the new windows, you would not have known we had any work done.  It was spotless - cleaner even than it was when they arrived!
While it is very early to really judge if they are sealed well, we carefully looked at all the windows and can see no gaps in the seals.  
I am more than satisfied with the whole experience with DiGiorgi.  They may not be the cheapest contractor out there, but I found their customer service and workmanship to be top notch.  I will definitely use them again when it comes time to replace the other 9 windows and the roof.  And I have no hesitation recommending them to anyone looking for quality products and workmanship, and professional, easy to deal with people for their next home improvement project.

Windows FAQs, answered by experts

Yes, egress windows can significantly add value to a home. By making basement and attic areas safer and more livable, they allow you to market these spaces as finished living areas, which increases your property's value. Many homeowners can recover the full installation cost, with some sources citing a return on investment of around 70%. The exact value added depends on your specific home, location, and adherence to local building codes. Beyond financial value, egress windows enhance functionality by adding natural light and comfort. They are also a crucial safety feature, often mandated by building codes to serve as an emergency exit.

The most common types of window frames include frame and sash, metal or aluminum frames, composite frames, fiberglass frames, vinyl frames, wood frames, glass or glazed frames, and insulated frames. Frames can also be categorized by operating types, such as awning frames, single/double-sliding frames, fixed frames, casement frames, and single/double-hung frames.

The maximum protruding distance allowed for a bay window is determined by its flank angles. 30-degree flanks can extend about 13 to 14 inches. If the angle is 45 degrees or larger, then the bay window can stick out about 19 inches. If the window extends too far out, it would cause structural instability and safety concerns.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.
