I am absolutely thrilled to write this review for Designer! From start to finish, Fredy and his team delivered an outstanding experience, culminating in the flawless installation of a brand new sliding door in my basement.
Choosing a company for home improvements can be daunting in Northern VA, but Fredy made the entire process seamless and stress-free. Their professionalism was evident from the initial consultation through to the final touches. The installers were incredibly skilled, efficient, and clearly took immense pride in their work. They paid meticulous attention to every detail, ensuring the door was perfectly aligned, sealed, and operated smoothly.
The quality of the installation is truly top-notch. There's not a single imperfection, and the new custom door has completely transformed the look and functionality of my basement. They also did an excellent job with cleanup, leaving the area spotless.
It's rare to find a company that combines such high-quality workmanship with exceptional customer service + honest pricing. If you're looking for a windows and siding company that delivers on its promises and exceeds expectations, I wholeheartedly recommend Freddy and his company. You won't be disappointed!

Fredy and his crew were very responsible, and get all the jobs done quickly . Fredy managed his crew to make sure everything was done correctly and professionally. Fredy and his crew had done some work on my residence and rental place. They replaced the roof and windows on both houses. In addition they just finished installing siding and replaced Gutters on my house. Fredy and his crew takes pride on their work and make sure that customers happy with ordered materials and effort that they put on to their work. I’ve been Fredy customer for many years. That’s because I trust Fredy and his crew and knowing that they will do excellent work . I am a one happy customer and strongly would like recommend “Designer Windows and Siding” for your next home improvement. Fredy will good take care of you.

We had doors, a window and gable siding replaced. Fredy was hands down the best business owner to work with. He is responsive, accommodating, courteous and flexible. He had different crews specialized in each project, one for windows/doors and another for the siding. We had specific ideas and designs that we wanted. Fredy listened and was willing to accommodate and provide us with options. He was never trying to push products or ideas on us and we never felt pressured on anything. We loved the doors/windows crew. They were on time, respectful, friendly and they did a great job. There were a couple of hiccups with the siding, but Fredy came out every day and we came up with fixes. We've worked with numerous contractors across various specialties. There was always some sort of frustration or argument with each project because the crew cuts corners and/or the owner is unwilling to listen to what we wanted. Fredy is the only contractor/business owner who we feel truly wants to listen and make his clients happy. He is happy to work with you to get to a final project that you are happy with without getting defensive and letting pride get in the way. On top of that pricing was reasonable. He is not the cheapest but he is nowhere near the most expensive. Highly recommend Fredy and Designer Windows and Siding.

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
