Why Window Condition Assessment and Repair / Replacement Matters
Older windows weren’t designed to meet today’s performance standards. As they age, issues like air and water infiltration, heat loss, and condensation become more common - and more expensive to fix. A professional window assessment helps identify these issues early and provides the information needed to evaluate repair or replacement options.
Evolving building standards affect window performance in several key ways:
Energy Codes – Modern windows are held to higher energy performance requirements that older systems fail to meet.
Materials and Systems – New technologies, such as thermally-broken aluminum or reinforced vinyl frames with double or triple glazing, far exceed the performance of past materials.
Building Envelope Compatibility – Existing exterior wall assembly construction, performance needs, and visual character all inform the design, detailing and installation of replacement windows.
Safety Standards – Window systems must meet current requirements ****for structural integrity and occupant safety, including wind load and impact resistance, bird friendly glass, limit stops, and custodial locks.
CANY's Involvement
Window upgrades in New York City, especially on mid and high-rise buildings, can be complex. At CANY, we guide clients through every stage of the process, with careful attention to budget, timeline and design intent.
Common Problems We Solve:
Energy Inefficiency –Excessive heat loss in winter and high cooling costs in summer.
Drafts & Leaks – Caused by aging frames, gaskets and seals
Condensation & Mold – Often a result of poor thermal performance and moisture intrusion
Noise pollution: Due to inadequate acoustical insulation
Outdated Appearance & Function– Diminishes tenant comfort and building value
Regulatory compliance – Failure to meet energy codes, industry standards, or local laws
And here’s how:
Assessment & Consultation – We evaluate your existing windows to identify conditions and present options for repair of replacement
Detailed Planning – We develop a tailored plan that considers existing conditions, design goals, performance, code compliance, installation logistics, and long-term value
Repair or Replacement – We recommend targeted repairs or full window replacement based on project needs, and manage the work to ensure it’s done properly, with minimal disruption to building operations.
Ongoing Support – Post-installation, we offer evaluations and maintenance guidance for long-term performance
