Company Philosophy

“We don't believe in using high-pressure sales tactics. Our initial estimates are competitive and fair; we won't start with an inflated price and try to coerce business by offering discounts. We respect our clients and take care of their needs throughout the entirety of their projects.”

Comparative Summary

American Window and Door Systems, Inc. has been selling and installing replacement windows throughout the Greater Bay Area since 1992. The family-owned and operated company has experience with all types of windows, including products from leading manufacturers like Simonton, Cascade, Milgard and Andersen. “Our salespeople are very knowledgeable,” says owner Eddy Deniz. “We don’t engage in high-pressure sales tactics or start with inflated prices and then negotiate down. We quote fair prices from the start.”

Unlike window companies that place more importance on their subcontractors’ availability than their customers’ schedules, American Window and Door Systems takes a straightforward, detailed approach to every project. Once a client contacts the firm, it sets up an appointment to measure the home or business and help select the type, brand and model of windows to be installed. “Often, we can provide a price quote right then and there,” says Mr. Deniz. “After the contract is signed, we order the windows and set an installation date. Our clients really appreciate such a streamlined process.”

Another distinguishing feature of American Window and Door Systems is its ability to quickly complete window installations. Most jobs take less than one day to finish, and the company provides long-term warranties for both labor and materials. “We always offer at least a five-year warranty, but it’s usually longer, depending on the brand,” says Mr. Deniz. “With Simonton windows, for example, we provide a lifetime warranty.”

Industry Info

Choose the right type of window for your particular environment and house style. Generally, it’s a good idea to rely on a professional recommendation when choosing a window style for your house, but it’s worthwhile to note that some window designs are inherently more efficient than others. Here’s a quick breakdown of the most common types:

Vinyl
Vinyl frames are typically the least expensive and virtually maintenance-free. They’re only available in light colors, though, because dark colors absorb too much heat from the sun and warp the frame.

Wood
A popular choice for aesthetic reasons, wood frames are typically only a little more expensive than vinyl, but they require diligent maintenance in order to prevent rot. They’re available in many species of wood and can be stained to match any existing décor.

Fiberglass/composite
Fiberglass frames are more expensive than wood or vinyl, but they’re also more durable. They require virtually no maintenance and can be painted any color (faux wood grains are also available).

Aluminum-clad
Aluminum frames are typically the most expensive, but they’re also maintenance-free and can take almost any color. They may not be suitable for coastal environments where saltwater is a concern.

Double-hung
These are traditional units in many homes across the United States, and they’re especially common in pre-war buildings. With double-hung windows, the bottoms slide up to open the units. They can be efficient choices, but they also have the potential to allow air intrusion between the sliders.

Casement
Popular in climates where wind is an issue, casements actually seal themselves off tighter when wind blows in toward the house. They require maintenance on hinges and seals to ensure their continued stability and efficiency.

Don’t overlook the importance of proper installation. Even the most expensive window unit won’t perform effectively if it’s not installed correctly. Be wary of any contractor who relies too heavily on expanding foams or sealants to get a window to fit—these materials aren’t waterproof and can lead to problems down the road. Pre-installation waterproofing, often completed long before the windows are installed, is the best option.

When shopping for energy-efficient windows, your first guide should be the National Fenestration Rating Council (NFRC) label. The NFRC is a nonprofit organization that provides homeowners and contractors with a standardized, unbiased method for comparing different brands and types of windows. The label will tell you a window’s U-factor, solar heat gain coefficient (SHGC) and visible light transmittance:

• U-factor is a measurement of the window’s rate of non-solar heat loss or gain. The lower the U-factor, the greater a window’s insulating value.
• SHGC is the fraction of solar radiation admitted through a window or skylight. The lower a window’s SHGC, the greater its shading ability.
• Visible light transmittance is the percentage of visible light that’s transmitted through glass. The higher the number, the more light the window admits.

Frequently Asked Questions

Q: What are some of the benefits of installing energy-efficient windows?

A: Aside from the vast amounts of energy and money you’ll save, energy-efficient windows improve comfort; reduce condensation; decrease drape, carpet and furniture fading; and lower mechanical equipment costs.

Q: How long will it take to install new windows in my home?

A: A typical home that has existing single-pane windows can usually be done in one day.

Q: Who will install my windows?

A: We employ our own full-time installers. We don’t use subcontractors, so if you have any problems with your installation, you deal directly with us.

Q: What is low-E coating?

A: Low-E coating is a virtually invisible coating of metal and metallic oxides that’s applied to glass. Low-E coatings provide year-round savings by reflecting sunlight and keeping your home cooler in the summer and warmer in the winter.

Q: Do you completely remove my old windows?

A: No. With replacement/retrofit windows, the outer perimeter frames of the old windows are left in place. The new replacement windows then fit over the top of the old frames and are sealed shut. By doing this, we ensure the exterior of your home isn’t damaged and there’s no patchwork to do on the stucco or wood siding. This can save thousands of dollars on the installation.

Q: Why do some companies remove the frame completely?

A: For a while, many companies were removing frames and installing replacement windows. That’s a problematic practice, because instead of being sealed to the old window frame, the replacement window is sealed to the home’s exterior. Since stucco and other sidings aren’t completely waterproof, this creates problems with sealing the window and preventing leaks. Because of this, we don’t recommend removing the old frames when installing a replacement window. If your dealer or contractor suggests using this method, look to somebody else.

Q: What kind of warranties do you offer?

A: We offer a fully transferable five-year warranty on all our workmanship. In addition, all the products we carry offer lifetime manufacturers’ warranties on any defects. Our higher-quality windows, like Simonton, carry transferrable lifetime warranties.

Q: Do I have any other installations options?

A: Yes. We can also install ‘nail-on’ windows, which are found in most newly built homes. To remove the old windows and install nail-on windows, we cut back the exterior stucco or siding of the home; remove the old window; install the new window using nails, flashing and caulk; and patch up the stucco or siding. Since this installation process is much more labor intensive, it’s considerably more expensive.

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Eddy Deniz

Expert CONTRIBUTOR PROFILE

Eddy Deniz is owner of American Window and Door Systems, Inc., a Diamond Certified company. He can be reached at (707) 879-8946 or by email.

Eddy Deniz: Adding Value

By James Florence, Diamond Certified Resource Reporter

NAPA—After finding success in commercial construction, Eddy Deniz took an opportunity to do what he loved on a smaller, more specialized scale. “I was born and raised on a dairy farm in Petaluma,” he says. “My father and I always did a lot of building and maintenance around the farm, and as a result, I gravitated toward construction. I went to college for construction management and then got a job with a large commercial firm. However, I had a passion to start my own business—something smaller and more akin to the environment I grew up in. I decided I should specialize in one aspect of the industry, so I chose windows and doors. In 2020, I got the opportunity to purchase American Window and Door Systems, which allowed me to branch out into the residential market.”

Today, Eddy says his favorite part of his job is adding value to his customers’ homes and lives. “I like seeing the finished product and the added value for the homeowner—not just property value, but aesthetic value and improved energy efficiency as well. I take a lot of pride in what my team and I are able to accomplish for our clients.”

A resident of Sebastopol, Eddy spends most of his time outside of work with his wife, Bethany, and their two children. “We enjoy going to the beach, attending the kids’ sporting events and vacationing at Lake Tahoe. I also have a large extended family, so we like getting together for barbecues and birthday parties.” Additionally, Eddy likes playing golf when the opportunity arises.

In regard to a professional philosophy, Eddy espouses the value of honesty. “We try to be upfront and honest with our clients,” he affirms. “I think it benefits everyone to be straightforward and tell the client what works and what doesn’t work. Whereas some companies try to quote the cheapest price or sell their customers something they don’t need, we just want to give them a good value for their money.”

When asked the first thing he’d do if he were to retire tomorrow, Eddy says he’d return to his farming roots. “I’d probably go back to the farm lifestyle—get some animals, plant some crops and spend my days working the land. I also have a couple of vehicles on my property that I’ve been meaning to fix up, so I’d finally be able to get those projects finished.”

Ask Me Anything!

Q: If you could travel anywhere in the world, where would you go?
A: I’d tour Europe and see all the historical sites.

Q: What was your favorite Halloween costume when you were growing up?
A: A Teenage Mutant Ninja Turtle.

Q: What’s your favorite thing to do on a rainy day?
A: Stay inside and watch sports.

Q: What are your favorite sports teams?
A: The San Francisco Giants and the San Francisco 49ers.

Q: Did you play any sports in high school?
A: I played football. I was a wide receiver and a safety.

3 Reasons to Consider Window Replacement

By Eddy Deniz of
American Window and Door Systems, Inc.

NAPA—It’s not always easy to know when it’s time to replace your windows, but there are a few signs you can look for, as well as considerations to make. Here are three reasons to consider window replacement:

Failed window seals
Have you noticed the presence of condensation or rust in between the dual panes of your windows? These are both indicators of a failed seal, which is a common sign that replacement is needed.

Diminished functionality
Another reason to consider window replacement is if your windows have ceased to function the way they’re supposed to—for example, if they aren’t able to slide freely or open properly.

Improved energy efficiency
If your home has single-pane windows or outdated dual-pane windows, you should consider upgrading them with stronger, more modern products. Besides reducing your energy bills, upgrading old windows can greatly increase your in-home comfort level.

Video: 3 Factors For Window Replacement

With Eddy Deniz of
American Window and Door Systems, Inc.

Complete Video Transcription

NAPA—Eddy Deniz: Some common things to look for, to consider when it’s time to replace your windows are condensation on the window glazing itself, or you’ll see rust on the interior of the panes, which would indicate failed seals of the window. You would also consider replacing windows when you currently have single pane windows—when you went on to upgrade to double pane windows to help reduce your energy bills, as well as the solar heat gain. Another obvious reason to replace your windows if it’s not functioning properly anymore, whether it’s not sliding freely or opening the way it’s supposed to.
