If you live in the West, replacing your vinyl replacement windows is a great investment. As demonstrated in the article below, the increased resale value of your home alone recoups the cost of the initial investment. Given that fact, the monthly savings on your energy bill is like cash back. Speaking of cash—if you’re a little short—LbL has same-as-cash financing available.

SIMPLE operation & maintenance

LbL windows are proof that looking good doesn’t have to mean diligent cleaning and constant attention. Unlike wood or metal windows, our custom vinyl windows will never rot, peel, flake, corrode or rust. This means that LbL windows will never need repainting and will retain their refined appearance for years to come.

Smooth & Intuitive Operation

When homeowners want to ventilate their home or enjoy a breath of fresh air, they don’t want to fumble with awkwardly positioned handles and locks. LbL windows are designed to operate simply and effortlessly. Exclusive Tilt ‘N’ Slide™ technology enables LbL windows to be opened completely for full ventilation, easy cleaning or emergency exit.

Years of Enjoyment without Daily Maintenance

Our custom vinyl windows are not only easy to use, but are also easy to maintain. The vinyl material used to create LbL windows enables easy maintenance and cleaning. While there are many vinyl formulations, lesser-quality vinyl windows are notorious for sagging under the weight of glass when in direct sunlight, while low-quality white vinyl develops a deep yellow tinge.

Quality Materials Make a Superior Product

LbL windows are made from high-caliber vinyl material made from only the highest quality ingredients. The American Architectural Manufacturers Association (AAMA) certification label on the frame assures the quality of all our vinyl windows and doors.

Easy to Maintain

This high-quality vinyl makes it incredibly simple for homeowners to maintain the look of their windows and products. LbL has made it even simpler by giving several of our window lines tilt-in sash capability that allow sliding windows to tilt and swing indoors, giving homeowners the luxury of cleaning the inside- and outside-facing surfaces within the comfort of their home.

LbL Windows' focus is the design and manufacture of high quality, innovative window products for the long-term performance and satisfaction of the homeowner. Every window is custom manufactured to the exact specifications to allow a perfect fit whether replacing your existing windows or installed as new construction.

LbL Windows' products offer high insulating efficiency multi-chambered frame designs with heat fusion welded frame and sash corners providing maximum strength plus dual weather-stripping to eliminate air and water infiltration. 80% of a window is glass. We have designed the Insulated Glass (IG) units to maximize thermal efficiency by eliminating metal spacers and introducing a non-metal "Warm Edge" spacer system that reduces condensation plus a dual seal spacer (acrylic seal structural bonds glass and secondary butyl moisture seal) that reduces noise and extends performance life well beyond that of metal spacer systems. Many high-performance glazing options are available to further enhance thermal or sound efficiency and/or beautify windows to your individual requirements. Unique matching, craftsman beveled exterior designs offer continuity while creating elegant classic lines.

LbL Windows' Lifetime Guarantee provides parts and labor for the original homeowner and transferable for two years to the second owner.
