Founded in 1962 by Arthur Lazeroff and named after his wife, Beverly Sally Lazeroff, BSL Direct is a second generation family business, now owned and operated by Mark Lazeroff.  

BSL Direct is the parent company of Wonder Windows™.  With locations in Rochester NY and Buffalo NY, BSL Direct and Wonder Windows™ are among Western New York’s most trusted window and door companies.

6 Decades of Windows and Doors in WNY

When you do something for over half a century, you develop a skill set that can only come with experience.  When we say we're a full-service window and door installer who’s seen it all, there's no exaggeration in that claim.  We have served thousands of customers over the past 60 years.

Regardless of whether you're building a new home, restoring an older home or business, or need a reliable source for high-quality, yet affordable doors and windows, you can trust BSL Direct and Wonder Windows™ every time.

Family Matters

At our company, we understand how important a home is. When you do business with our family, we will do right by yours. Our margins are modest.  We provide the highest quality products in every price range and we’ll be with you on your home improvement project every step of the way.

Our professional installers will remind you what customer service is all about.  Our goal is to always leave you wanting to tell everyone how satisfied you are with the quality of our products, our workmanship and our professional installation.

Extensive Selection of Windows & Doors

In addition to our extensive selection of premium OKNOPLAST windows and patio doors, we also carry an exclusive line of Insul-Tec and Enviro-Star windows.  Additionally, we stock and distribute a wide-range of wood and vinyl windows from the industry's most sought-after manufacturers: Anderson, OKNA, Trimline, Simonton, Ply Gem, Certainteed and others.

Skilled Staff Window Installers

While some WNY window installation companies use subcontractors or outsourced labor for installations, BSL Direct takes a more hands on approach.  Our thoroughly trained professional installers use techniques that BSL Direct and Wonder Windows™ have been honing since 1962.

We understand that for many homeowners and businesses, new windows aren't always in the budget.  BSL Direct can finance all your window and door needs, and we offer the most competitive pricing and rates in WNY.  We make it possible for you to get the new or replacement windows you want today.
