[#1]Why Are Window Replacements in NYC So Costly?[#1]

Unlike private homes, window replacements in NYC co-ops and condos are significantly more expensive due to a number of factors including requirement of customized windows, building regulations, insurance requirements, and other factors. Pricing out window replacement in an apartment building can be shocking for those accustomed to typical residential home costs. NYC buildings often mandate certain materials, designs, and standards to uphold the city’s unique architecture and building rules, which drives up both material and installation costs.

Determining Your Vendor Options

In many NYC buildings, window replacements come with specific vendor requirements, which can affect your options and budget:

Building-Specified Vendors

Some buildings mandate the use of approved vendors, such as Skyline or Panorama, to ensure compliance with their standards. In these cases, homeowners have two options:

• Work directly with the designated vendor for installation
• Engage a full-service renovation firm like Gallery to manage vendor coordination within the broader renovation scope

Open Vendor Policy

Other buildings offer more flexibility, allowing homeowners to select any licensed and insured vendor. While this can sometimes reduce costs, the overall expense remains high due to NYC’s bloated building requirements.

Replacement Methods: Frame-To-Frame vs. Brick-To-Brick

Not every window renovation is created equal. There are two main types of window replacement and the method you choose impacts both the cost and disruption level you’re willing to accept.

Frame-To-Frame Replacement

This approach involves minimal disruption as it keeps the original window frame intact. Frame-to-frame replacements are often more straightforward and budget-friendly, involving only the new windows and installation.

Brick-To-Brick Replacement

This method is much more invasive, requiring complete removal of the window structure, including the frame. There’s also additional work, such as plaster repair, all of which increases both time and cost involved. However, the added necessity often proves worthwhile, as brick-to-brick replacements provide enhanced energy efficiency and can restore a building’s original appearance—ideal for historic renovations. 

Navigating Landmark And LPC Requirements

If your building is in a historic district or holds landmark status, additional steps are necessary to maintain that age-old architectural integrity:

LPC Approval Process

For landmarked buildings, approval from the Landmarks Preservation Commission (LPC) is mandatory, adding another layer of review on top of Department of Buildings (DOB) permits. This can increase both the time and cost required. 

Specialized Windows

Landmark status often requires specific window styles or materials that match the historical character of the building, which can also add to your project’s expense.

‍[#2]Special Window Types And Features[#2]

Certain window types and features come with added complexity and cost considerations in NYC: 

Lot Line Windows

Windows positioned along property lines or shared walls require enhanced fireproofing and noise reduction features, making them more costly with longer lead times due to specific material requirements.

Additional Features

Window technology has leveled up in recent years and now windows in NYC apartments can be outfitted with special features such as UV protection, soundproofing, or smart technology. While these add comfort and functionality, they also come at a premium.

[#3]Building-Wide Replacement Programs And Special Assessments[#3]

In some co-op or condo buildings, window replacement is a collective project. So, before you take on full costs yourself, consider the following building-specific considerations. 

Cost Inclusion

Buildings may cover the expense through maintenance fees or a special assessment, which is an additional fee that covers the renovation costs. Hey, why not?

Special Assessments

If you’re a prospective buyer, you might ask about any requirements for building-wide window replacements to avoid unexpected costs after moving in.

[#4]Essential Questions For Your General Contractor When Hiring For Your NYC Renovation With Window Replacements[#4]

While we have a specific blog catering to 10 Questions To Ask A NYC General Contractor Before Hiring, here are some window-centric questions to note when preparing to hire a contractor for NYC renovations.

Are There Vendor Restrictions? 

Some buildings are strict about the windows you use upon replacement. Before making any selections, determine if your building mandates specific vendors or if you have more freedom in choosing one.

Which Replacement Method Is Required? 

As discussed, there are benefits to both brick-to-brick and frame-to-frame window replacements. Preference aside, your renovation may actually call for one or the other depending on the requirements of your building. To handle the replacement properly, ask your potential renovation contractor exactly which route they feel is required or what route your building mandates. A full-service design-build contractor will not only answer this for you, they’ll speak with your building to confirm the route is approved. 

What Are The Lead Times?

Certain window types and compliance requirements may lengthen production and installation times. If the window replacements are part of a larger renovation and you’re working with a design-build general contractor like Gallery, extended lead times for windows will be a non-factor, as various other aspects of the renovation will be moving forward amidst the wait.
