Greater Washington Location Overview
GDI/Patio Enclosures/Stanek Windows has served the Metropolitan Washington DC and Washington areas for over 3 decades with over 15,000 satisfied customers. As a full service remodeler, we understand the comfort our customers have knowing they’re dealing with a business that can give them “Big Company Support”. And at the same time, we are a family business who takes great pride in each individual project no matter how modest or grand so we also understand the comfort our customers have in knowing they get “Small Town Service”.

As building codes and construction techniques have changed over the years, it is more important than ever that you choose someone who will take responsibility for your project through the following steps:
• Idea • Design • Permits • Manufacturing/Ordering • Installation • Clean up • Service and warranties

Unfortunately in today’s marketplace, people equate “free in-home estimate” with a three-hour “high-pressure sales pitch”. At Great Day Improvements LLC, we do not operate that way. We appreciate every opportunity to meet with homeowners and discuss the projects & dreams they have in mind. We will evaluate your situation, make suggestions and show you how we would approach it. Sometimes this can be done on our initial visit. Sometimes it might take several visits. Whenever you decide you’re ready to move forward, we want to be the ones you choose.

If you’re ready to explore the possibility of building that sunroom you’ve always wanted or upgrading your windows and siding to energy efficient products…. If you’re ready for a deck that you don’t have to maintain every year… If you have a deck or a patio but it’s just too hot to use and you want to cover it with a retractable awning…. If you’d like something a little more decorative than that cracked concrete slab in your back yard… or if you just need additional living space for your growing family… Then you owe it to yourself to set aside an hour or so and let one of our professionals give you an honest, no-hassle evaluation…
