Value Engineering
Value Engineering
Aluminum
Aluminum window installation and repair in NYC is offered by WindowFix. Modern aluminum provides a versatility and performance that was unheard of even a few short years ago. Advances in energy technology now allow us to offer products with greater insulation (with a ”thermal break” in its construction), superior durability, and design options to rival most any other material. Aluminum can replicate traditional steel and wood in more economical packages, with standard and custom colors, multiple styles and configurations, for the most demanding users.
Architectural Steel
Today’s modern architectural steel window frames are a designer’s dream. Available in hot-rolled and cold-rolled varieties, steel windows offer narrower sightlines than competing materials. Modern products also provide superior insulation compared to aging steel windows. With New York City’s stringent energy codes, now may be the right time to upgrade.
Curtain Wall / Storefront
Over the past ten years, curtain walls have become a standard for modern buildings all over the world. Often encompassing a floor-to-ceiling installation of glass, they create a striking environment not just in commercial buildings but in an increasing number of private homes. Curtain walls can be as low as one story or as tall as the Freedom Tower, and we at WindowFix can source, install and maintain curtain walls from manufacturers across the globe as well as here in U.S.A
Fiberglass
Due to its strength, fiberglass is touted by some manufacturers as “perhaps the perfect building material”. It is certainly stronger structurally than vinyl and requires a different manufacturing process. A great advantage is its compatibility with glass through changes in weather and temperature, and this adds up to a long lasting, high performance product.
High Performance Vinyl
Our preferred high-performance vinyl window manufacturer, Kensington High Performance Products, offers perhaps the industry’s best combination of affordability, quality, and superior energy efficiency. Suitable for residential uses, Kensington vinyl comes in an assortment of standard and custom color options, with outstanding performance, durability, and delivery time.
Passive House
Passive House windows and doors are a new benchmark in sustainable design. It’s a building standard that maximizes air tightness and insulation, in order to minimize energy costs. Openings such as windows and doors are the greatest source of heat loss in any home, and so our industry developed new technology to meet this demand.
Sound Reducing
Being based in NYC, we receive calls every day for our guidance on how to reduce sound. No window we use is completely soundproof, but there are a number of options to reduce noise significantly, even on the loudest streets and avenues in our city. One option is an interior application, or perhaps something as simple as adding a storm window. We can also configure multiple panes of glass, or varying thicknesses, to naturally and scientifically disrupt sound waves. Call us to discuss what would be the most appropriate solution for you. Various STC/OITC ratings are achievable.
Wood
To this day, wood stands as one of the most time-tested and widely beloved materials to use for residential and commercial windows. Wood windows are versatile and have plenty of design and appearance options, offer superior durability, and require only a moderate level of maintenance to keep them looking stunning.
Curtain Wall / Storefront
Over the past ten years, curtain walls have become a standard for modern buildings all over the world. Often encompassing a floor-to-ceiling installation of glass, they create a striking environment not just in commercial buildings but in an increasing number of private homes. Curtain walls can be as low as one story or as tall as the Freedom Tower, and we at WindowFix can source, install and maintain curtain walls from manufacturers across the globe as well as here in U.S.A
Entry & Storm Doors
Does your home’s front entrance make a good first impression? Perhaps you wish your entry door were more aesthetically pleasing, or you have security or efficiency concerns. No matter what problems you hope to address, replacing your entry door or installing a storm door could be the right answer. Window Fix installs high-quality entry and storm doors from ProVia and other top brands. We’re a family-run, customer-focused window and door company based in Brooklyn. When you work with us, you can expect responsive service and the best guarantees in the industry.
Glass
Whether installed on the interior or exterior, glass doors can improve the aesthetics and functionality of any building. WindowFix is pleased to offer glass door services for homes and businesses in NYC, including installation, replacement, and repair.
Insulated
Also called double-pane glass, it consists of two pieces of glass, with a moisture-absorbing sealant between them. Insulated glass can only be installed into windows or openings that are prepared for this purpose.
Low E/Energy Efficient
Window-Fix Low E Glass solutions meet all ENERGY STAR® programs, low-e products have established new standards for energy efficiency and year round value. For homes, businesses and architectural projects, Low E Glass offers day-to-day comfort and year-round energy performance.

Retractable screens can be installed in doors, windows, and large openings. Signature colors or custom match including wood grain. Mesh options for insect protection, shade, and privacy – even black out.
Our Story
Thirty-five plus years ago, our family started providing window treatments and repairing glass on Church Avenue. We had fewer than fifty small jobs our first year and now do about that many every day. However, as our market expanded, we never got away from our roots. Today we still repair and install window products across New York City, but just as importantly, are able to provide value engineering and consultations to meet the modern demands of the industry. Whether you need a source for fire-rated windows or ADA doors, a replacement for obsolete industrial windows, or guidance on energy-efficient options, look to WindowFix as your go-to source.
“Thank you for a great experience. The whole process was seamless, which is always a nice surprise. From the initial assessment to the actual repair work, everything was done quickly, efficiently and professionally. Kudos to Ernie and the window mechanics. I would highly recommend Window-Fix in the future.”
