Diamond Certified Researched Articles on Abstract Windows

researched article

Abstract Windows installed the windows at this housing complex.

Abstract Windows installs and sells a variety of windows and doors for residential and commercial clients in San Mateo County, San Francisco, and the Peninsula. In addition to working with everything from vinyl and fiberglass windows to French and patio doors, the family-owned and operated company is qualified to offer supplementary services like waterproofing and siding installation.

Owner Dimitar Georgiev credits much of Abstract Windows’ success to its meticulous, detail-oriented approach to every project. “We have one rule: respect the opening,” he says. “That means each window or door that we install has to be proper for that particular opening. By listening to our customers’ needs and utilizing our expertise, we’re able to come up with solutions that are better for their homes in the long run.”

Abstract Windows provides a personal touch in every aspect of its work, which Mr. Georgiev says is important for establishing trust with clients. “Our customers like that instead of dealing with a big corporation that only cares about numbers, they can talk directly to the owner of the company and get their questions answered. Their satisfaction is everything to us, so we make sure they feel the personal touch throughout their projects.”

“Our number one goal is to make our customers happy and confident that they chose the right company. We want to maintain long-term relationships with them and earn their referrals, so we never mislead them or go for the quick buck. Ultimately, we want every customer to feel like they’re part of our family.”

The difference between new construction windows and replacement windows is more than cost alone.
When your windows are old, drafty, leaky or losing their energy efficiency, it’s time to upgrade. But you have a choice to make: Should you hire a contractor to install replacement windows or should you request new construction windows?

“Most homes look best with new installations rather than replacements or retrofits,” says Dimitar Georgiev, owner of Abstract Windows in San Carlos. “A lot of companies try to push their customers toward retrofit installations because it’s an easy process and easy money, but it’s not right most of the time in terms of aesthetics and value. If a home faces west or is near the ocean, it’s better to install new construction windows that have new flashing, Z bars and components that maximize energy efficiency.”

What’s the difference between replacement windows and new construction windows?
Replacement windows slip into the openings where old windows were removed. They don’t have flanges, flashing or nailing fins. New construction windows are complete window units that fit into openings that aren’t surrounded by trim. They include nailing fins or flanges and are installed like brand-new window units. They’re often preferred for new construction projects and remodels or when existing window frames are damaged or deteriorated. However, window companies that are focused on quality and long-term value often recommend new construction windows that give homeowners the benefits that come with brand-new window installations.

Because they’re full products that take more time to install, new construction windows are usually more expensive. However, they often come with less risk of leaking and will function like brand-new windows. Replacement windows and retrofits must be specially ordered to fit into the existing wall gaps, and they rely on the structure of the old windows to be watertight and efficient.

“New construction windows give you a new platform for your windows so they’ll operate better for years to come,” affirms Mr. Georgiev. “That being said, you should always talk to your window contractor to discuss your budget, check your existing frames and decide on the best path forward.”

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for window companies that have earned the prestigious Diamond Certified award. For Abstract Windows, keeping clients happy is all about doing what’s right for their particular situations. “Our goal isn’t to finish the job and move on to the next one—it’s to provide a personal touch that leaves the customer completely satisfied,” says owner Dimitar Georgiev. “Ultimately, we want them to feel confident that they chose the right company to handle their project.”

Abstract Windows has been installing and selling windows and doors for residential and commercial clients in San Mateo County, San Francisco, and the Peninsula since 2011. The family-owned and operated company works with everything from vinyl and fiberglass windows to French and patio doors, and it’s also qualified to perform supplementary work like siding installation and waterproofing.

Unlike less experienced window companies that take an “assembly line” approach to each project, Abstract Windows takes the time to personally connect with its customers so they feel more connected to the process. “People want to know who they’re dealing with so they don’t feel like just a number,” offers Mr. Georgiev. “Customer service has always been important to us, but in this digital era, it’s easy to find reviews and complaints about companies, so it’s more important than ever. We’re honest and fair, we train our employees well, and we treat our clients with respect so we can continue to grow.”

Abstract Windows further differentiates itself from its competition by exclusively working on windows, doors and siding, which allows it to offer a high level of expertise on each project. “A lot of contractors do everything from windows to complete kitchen remodels, but we prefer to focus on a few things so we can do them extremely well,” explains Mr. Georgiev. “We want to be proud of everything that we do, so we pay attention to details and remain in control throughout each step of the process.”

Dimitar Georgiev: A Window of Opportunity

By Matt Solis, Editor

Dimitar Georgiev didn’t have a lot of experience when he entered the window industry in 2003, but it didn’t take long for him to master the craft. “I started as a helper for a company that installed vinyl retrofit windows,” he remembers. “After nine months of learning the trade, I became a lead installer—they gave me a company truck and I started leading jobs. Three years later, I moved on to Andersen Windows and worked there for a few years. Eventually, ...
