Case Study: Egress Window Installation in Hempstead, NY
Egress window installation in the basement of the house in Hempstead NY.

Client: Residential Homeowner
Location: Hempstead, NY
Service Provided: Egress Window Installation
Project Type: Basement Safety & Ventilation Upgrade


Project Overview

Zavza Seal LLC was hired by a homeowner in Hempstead, NY, to enhance the safety, compliance, and natural lighting of their basement by installing a new egress window. The existing foundation window was too small to meet safety codes for emergency exits, and the client was also concerned about improper ventilation and moisture accumulation in the basement.

Our team proposed a comprehensive egress window installation solution, which included enlarging the window opening, improving drainage, and installing a durable and code-compliant window and well system.


Client Goals

  • Upgrade the basement to meet emergency egress codes
  • Improve natural light and airflow in the basement
  • Prevent water accumulation by adding proper drainage
  • Ensure the installation is code-compliant and watertight

Zavza Seal’s Proposed Solution

Our experts at Zavza Seal LLC carefully analyzed the structural integrity of the foundation wall and the client’s existing window. To comply with safety codes and improve basement usability, we developed a three-step plan:

✅ 1. Excavation & Drainage Preparation

  • We excavated around the foundation wall where the new egress window would be installed.
  • To prevent water buildup, we added an 18-inch gravel bottom at the base of the new window well to promote proper drainage and minimize hydrostatic pressure against the foundation.

✅ 2. Window Opening Enlargement

  • The existing basement window was not sufficient for emergency egress.
  • We enlarged the foundation opening to a depth of 45 inches, ensuring the dimensions meet NY State building code requirements for basement egress windows.

✅ 3. Installation of Egress Window and Well

  • We installed a code-compliant inswing egress window to ensure easy exit in case of emergency.
  • A new egress window well was set in place, anchored for durability and filled with gravel for drainage.
  • To prevent water intrusion and debris accumulation, we added a clear exterior rain cover over the window well for long-term protection.

Project Outcome

  • The basement is now code-compliant, safer, and better ventilated.
  • Natural light levels increased significantly, making the basement more usable and inviting.
  • The newly installed drainage gravel base ensures water flows away efficiently from the foundation, reducing moisture risk.
  • The clear rain cover protects the well without blocking light or air.
