Since its inception by co founders William Barr and Michael Strmac in 2002, Universal Windows Direct has lived by the philosophy of CANEI - "Constant and Never Ending Improvement". This philosophy holds true in all aspects of our business, from sales and marketing to installation and service and has catapulted UWD from a small, local home improvement company to one of the largest exterior remodeling companies in the country. Every one of our employees strives continuously to be the best in the business at what they do and provide our customers with only the highest levels of sales, service, and support. We think our company's history speaks to this goal and to the power of what we can accomplish by never settling. Universal Windows Direct of Pittsburgh opened in 2019. Our products feature the exclusive UniShield brand and come with a transferable lifetime warranty on materials and labor. We are a fully licensed, bonded, and insured company and EPA Lead-Safe certified. In addition, a portion of every sale goes to support a growing list of local charities.

"*posting so you can make informed decisions as a consumer In January of 2022 we purchased full house windows and doors from Universal Windows Direct. It took 10 months, but they were finally installed in November of 2022 by a sub-contractor from out of state. These videos were taken after a large summer storm in early July 2023. Their warrenty specialist visited the home thinking that they needed to simply repair these two… however, he found that EVERY SINGLE WINDOW WAS INSTALLED INCORRECTLY. None of them were properly sealed or wrapped from the outside, meaning that water (and consequential mold) was building up in the walls for 7 months before breaking down a these windows’ internal seals. We’ve also come to learn that electrical hazards were imminent, specifically in our toddlers room (video 2). Every wall, floor, and ceiling of the beautiful home we had built ended up needing to be ripped apart because a national window company improperly installed our windows. The total cost of damages and repairs ended up surpassing $300,000 and our family of 2 adults, a toddler, and an infant were displaced from our home for 9 months. Mitigation and restoration was completed in February of 2024 and UWD was cooperative with that matter. However, customer service and management/operations at Universal Windows Direct were abysmal to work with. I post simple statements and share our consumer experience so that others, as potential consumers, can understand to make informed decisions. I urge you: know your rights as a consumer, read your contracts thoroughly, read as many reviews as possible on sites like neighborhood group pages, Angies List, Google, Yelp, and the Better Business Bureau. PLEASE don’t end up in a situation like we did, having our lives uprooted and our mental health imploded."

"I am sure that all positive reviews for this company are fake. Nothing that was promised to me was delivered. My siding project is still ongoing for over 1 month. Was told that it would be done in week. Had one rain day. They have system like this: 1) sales person who never installed anything he will promise you things that obviously are not true, 2) crew that is subcontracted but not Gunner, mine was driving for over 2 hours away, 3) person who oversees the project but has little control over anything, no supply, doesn't know the crew, crew does not listen to him, main office does not listen to him, 4) main office does not reply to you. They just tell me to talk to project manager who has no control. So you understand that if there are any issue you are on your own. Quality or work is not good. Many times I had to point to the crew what's wrong, planks are broken yet they were still installing it, caulking is done they way that I can do it better, they cut wires to awning etc"

Windows questions, answered by experts

When it comes to your pocket, opting for energy-efficient windows can lead to an average of 12% in energy bill savings. That totals to yearly energy savings between $100 and $600. However, the exact amount you’ll save hinges on factors like your local climate and the number of windows in your home.

Yes, bifold windows can open inward or outward. Your window manufacturer will label windows as “in-swing” or “out-swing,” which indicates the direction they open. If your installer is ordering windows for you, make sure they know which direction you want them to open. In-swing bifold windows will preserve as much space in your outdoor area as possible. Out-swing bifold windows are great on the second floor, where obstructions outside aren’t a concern.

Yes. Vinyl windows have a PVC frame that wraps around a glass panel that is usually made up of two thinner glass panels separated by an insulating, noise-absorbing airspace. Some vinyl windows are triple-glazed, with three insulating air panels within them. This glass helps keep your interior quiet from outside noise while its insulating qualities help your space stay cool in the summer and warm in the winter.

On average, replacing your windows can cost anywhere from $180 to $410, which breaks down to an average of $280 per window. It all depends on the size of the window you’re installing and the frame and glass that you choose. Other things a contractor might take into consideration are the age of your home, the condition of the walls, and where you’re installing the windows.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.
