How do I know if I need my windows replaced?


Your home deserves the ultimate window performance.

BNW Builders provides high-performance window replacements to homeowners throughout the Richmond and Central Virginia area. Our top quality products, detail-oriented design team, and expert advice will deliver the window replacement solution you’re looking for.


Cutting edge energy efficiency and low maintenance replacement windows.

BNW Builders is proud to carry a full range of Infinity® from Marvin® replacement windows. These best-in-class windows are a high performance, low maintenance replacement window option that feature innovative yet timeless designs and cutting edge energy efficiency. Featuring industry-leading Ultrex® pultruded fiberglass, your replacement windows will be weather-tight and unbeatably durable. Ultrex® is eight times stronger than vinyl, expands 87% less than vinyl, and is resistant to leaks, seal failures, and stress cracks, all of which can make your home less energy efficient. By combining more glass and a narrower frame, Infinity® from Marvin® windows let in more natural light and help to increase your home’s energy efficiency.

Why choose Infinity fiberglass windows?

Infinity windows are made from the strongest window framing material in the window replacement industry. In addition to their strength, these windows are designed to hold their shape. Unlike vinyl, they expand and contract very little with changes in the temperature. This prolongs the life of the windows and maximizes performance so you get a tight, snug fit that will last.

The new standard for performance window glass.

BNW Builders has lofty goals for your home’s energy-efficiency. With The Wiegan Heat Mirror Window™, we’ve delivered the most energy-efficient solution on the market. Heat mirror windows feature thick, insulated glass that’s been specially designed to enhance the comfort of your home. Depending on the materials used, these windows can insulate as well as a standard wall! The added insulation allows The Wiegan Heat Mirror Window™ to eliminate outside noise by up to five decibels, block over 99.5% of harmful UV rays, increase your home’s energy efficiency, and so much more.

How Heat Mirror® technology works.

A lightweight polyethylene terephthalate (PET) film is suspended inside the airspace of dual-pane insulating class to create multiple super-insulating cavities. This provides center glass insulation performance to R-5.6, offers superior winter heating and summer cooling due to the multi-cavity design, and reduces condensation buildup on glass during winter. Remarkably, it does all of this while weighing about 1/3 less than triple-pane glass.

The Wiegan Heat Mirror Windows’™ unbeatable performance is thanks to the industry-leading products we use to build it. We use EcoClean foam throughout the frames and sashes. EcoClean foam is a USDA certified BioPreferred® product and provides energy efficient thermal performance. Combined with the heat mirror glass, this foam provides unmatched comfort. We also use Sunshield PVC on the frames and sashes, which has been enhanced with titanium dioxide to block ultraviolet light.

100 percent satisfied with all the work done to my house. I had siding, windows , doors and gutters. The job was done quickly and on time at a reasonable cost.

I have to say my experience with BNW Builders and Bruce was exceptional. I had interviewed two other companies for replacement windows for my entire house. BNW had a better product and were the most professional and responsive. It was a clear choice to go with BNW. Now after all my 18 windows are in....we love them! What a difference in cooling and heating. I did not realize how drafty my house was until all the new windows were in. Another unexpected benefit was that it was so much quieter. I could barely hear anything from the outside.

WOW what a terrific pleasure to work with a company who was friendly, knowledgeable, punctual and professional in every way with a product that far surpassed anything that I thought it should be. From the first phone call, speaking with Bruce to working with the salesman, and Jerry the installer, it was a dream. Everything about the job was A+ and I can't recommend them highly enough. WELL DONE - I can't wait to be able to finish the rest of my house. Not only were my husband and I impressed but my neighbors and friends as well.

New exterior door installed. The workmanship was excellent and the quality of the door is also. They even came back to fix something they weren’t happy with. I wouldn’t have noticed what was wrong. Our experience is that they are great employees and an honest company.

Over the years BNW has replaced our siding, rebuilt our porch after a fire, and replaced several doors and gutters. The professionalism and interest in getting the job done right, as well as the quality of the products they use, IS the reason we always come back. Brue and his team have become like family in the 20+ years we have been doing business with BNW.

We’ve used BNW Builders in the past too when we lived in Chesterfield for new siding, roof, gutters & shutters. Bruce and his employees are the best! I would definitely recommend BNW Builders for any home improvements. Absolutely stress free and they definitely pay attention to every detail! I wish they had a second location in Winchester!! I would definitely hire them again!

Level of initial detail from BNW Builders to define and understand the Sliding Glass Door options plus the installation process was excellent. Communication with the main office and project coordinator was also very good from Contract signing through installation. Field installation personnel were superb, being on-time, courteous, respectful to being inside of one's home, laying tarp/cloths down both inside and out, and very helpful to respond to a host of questions about the installation and product before they left. Project well done! Very trustworthy organization.

BNW Builders just finished a screened in porch project at our house in Readers Branch. My wife and I are pleased with the results and the quality of the work is outstanding. The BNW crew and subs performed exceptional work. They made sure we were well informed about the progress of the job, our lawn was protected from damage and all of our questions were answered. You can be sure we will recommend BNW to anyone who asks us about the project.

We have done three projects with BNW Builders. The first was a large porch project. We demolished an existing deck and built a large covered porch with the Easy-Breeze window system, electrical and a large grilling deck. We were so satisfied that we recommended BNW to several neighbors. Since then we have added a Provia storm door and Gutter Shutter. The work has been flawless and done on time. I would not hesitate to use them again.

When our neighbor recently replaced his windows and put up new siding, we were so impressed with the job and the crew working there, that we immediately called BNW to do our home. Bruce was very responsive and we were able to get a quote and schedule the work within a couple days. The installation went smoothly and we are thoroughly pleased with the results. The house looks like new and is a lot quieter too with the new windows. BNW is at the top of our call list for future home improvements. Thanks Bruce!
