Excellent company to work with! I have been dealing with Tower Insulating Glass since starting my business and cannot be more happy that I was referred to them. The insulated units I have purchased have been manufactured quickly and perfectly. They are a very accommodating and easy to work with company. The shipping coordinator went above and beyond to ensure my delivery would be made to a very particular contractor. I appreciate all of their hard work and look forward to a bright future with Tower.

I have been ordering from tower about 5 years now. I have to say, the quality in product has consistently been excellent in comparison to competition. Service has always been prompt and more than accommodating. Even tempered insulated windows are turned over quicker than initially anticipated. On top of it, I always get laughs and smiles from the ladies in the office. Always a pleasure to work with.

I have been purchasing glass from Tower for over 20 years. They always come through with whatever glass I need. If there is a glass that can't be found, they can find it, and the quality is the best. The office staff are always available to help. Very accommodating. Even for the delivery. Highly recommended!!

We have been using Tower Glass for almost 28 years! The quality of the glass units is superior! I can say that in all of those years, I can count on one hand the number of units returned for failure (and that was years ago!). We propose our glass units as "IGCC Certified"; and we educate our customers on what that is, and why it is important. Tower Glass has always been able to help us find the best solution for our customers, and help us match obsolete coatings which is always an issue in this industry! When selling large projects, I find it important to have all options for our customers to consider, and Tower Glass has been key in providing all of the information to help our customers make an informed decision.
Tower Glass is truly a valuable resource in this industry! Anyone can make an insulated glass unit in their garage! Tower provides quality and longevity to our projects, and in today's market where the cost of labor frequently exceeds the cost of the products by many multiples, getting the right glass installed in a timely fashion the first time is key! Tower helps us achieve these results, and this is why we rely on them as a trusted resource! Congratulations to Tower and keep up the good work!

As a window supplier, we have worked with Tower for years and have always come to them for their speedy responses, product consistency, and their extensive product line. Recently, we were under pressure to resolve a broken glass issue and Tower's sales team and management went above and beyond to help us get it done. Thank you again Marjorie, Marybeth and the whole team at Tower for consistently delivering!

I’ve had the pleasure to work with Barry & Co. at Tower Glass for many years. They are all consummate professionals with enormous experience and deep knowledge about the near-limitless matrix of glass fabrication. If it’s possible, they can craft it with precision and care – delivering on time and on budget. They are the gold standard, operating at the very top of the trade.

We have been working with Tower for a very long time now and it is due to their ability to make what others will not, and their impeccable quality. Even when we have issues with the glass received, Tower is very quick to remedy the situation. Their team is professional and very well versed in all things glass. They are a perfect example of "you get what you pay for". They are expensive, but the quality is second to none.
