Unlike other companies we don’t just TELL you something will look good - we SHOW you. We provide full color 3-D renderings of all of our products to show what they will look like on your home PRIOR to you making any decisions or signing a contract. We do this for free the first time we come out as part of our free estimate & design consultation. With the Forever Guarantee along with full color 3-D designs before you make a decision - our goal is COMPLETE peace of mind for all our customers. We then follow this up with top notch communication, customer service, skill, and quality for Virginia's leading exterior replacement experience.

"Great service, they are experts in sidings. They explained the material, cost, etc. Flexible in starting date and payment plans. Strongly recommend them"

Since 1987 UNICORP Home Energy Services has made window, siding and roofing projects a worry free experience for over 23,000 homeowners in MD, VA and Washington D.C. We are proud of our flawless record with the Better Business Bureau because customer satisfaction is our number one priority. Our past partnerships with Price Club (Costco) and more recently Pepco Energy Services are a clear indication that we understand the importance of providing substantial savings and value on all our energy saving products. ---- At UNICORP we don't believe in hard-sell tactics, and never make cold calls that interrupt you at meal time. We understand the importance of making the right decision without headache or high pressure. That's why more customers refer us to their friends and family than any other window and siding company. Not surprising when dealing with professionals that care about their customers and love what they do. ---- We thank you for visiting our profile and look forward to improving the quality, enjoyment and energy efficiency of your home. ---- Additional phone - (703) 462-6100.

"We hired Unicorp to change front door because of superb review on Angi, but disappointed. 1. It's a small company using subcontractors to do its work; Contrary to its claim, those subcontractors DO NOT work exclusively for Unicorp. 2. After subcontractors got paid, you will not see them again for the job. The service team seems only one person (JR). It is hard to make an appt, since he has to supervise a lot of subcontractors' work, and only do service when he is supervising near you. Specific problems: -Ghost swing after installation (i.e. door swings to close by itself). Had to request adjustment at least twice. -Fainted finish after a few years while still in warranty, but we were advised to paint ourselves. -Very thin layer of finish, and very easy to get scratch to show white underline color; -Have PROBLEM to LOCK the door. After it was "fixed", problem showed again. -Subcontractor used wood with black stains, suspect mold, to install the door; Brand new door had minor defect."

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"We hire Window Nation to replace 10 windows at our house, after a few months one of the panel leaked and was defective. Window Nation replace the panel at no cost under their warranty. We are very satisfy with the process and would hire them again to replace the remaining windows at our house."

"Our review is based on the purchase (part 1) for replacing siding for both side of our home. Jacob L. was very professional, on time, and honest. He knows what he is selling. We learned a lot about our home during his presentation. Before we bought our home we paid for a professional home inspection. We thought our house inspector was very good but he did miss something---the siding on the sides of our home was installed extremely bad. Jacob pointed out so much that we just didn't know and should have be caught during our home inpection. Thanks Jacob!!"

New windows services FAQs

No, bow windows aren't outdated, especially if you own a Victorian-style home. They make an elegant architectural touch in most settings, and they're usually a unique addition to any home from any era. Bow windows are also excellent for increasing natural light inside the house while adding an upgraded design aspect to the exterior. For your project, talk to a local architect.

Bow windows require a permit when the installation extends the structure outward because the modification qualifies as a home addition. This requirement applies in regulated areas such as historical districts and homeowner associations. Homeowners must secure full authorization from local municipal authorities before beginning installation. It is essential to verify specific guidelines with your local building department to ensure complete compliance with all permit requirements and safety standards.

Bow windows by themselves don't typically increase a home's value. However, adding architectural upgrades to the outside of the house, such as custom trim, dormers, and bow windows, might increase your overall sale price. If it matches or only slightly exceeds upgrades and architectural styles in your neighborhood, you're more likely to get a higher asking price. It'll make your house stand out, making it easier to sell.
