New Garage Door Installation & Sales in Maryland, Virginia, and Washington D.C.
Your garage door is more than just a moving wall; it can cover up to 40% of your home’s facade. It is the first thing neighbors see when they drive by and the last thing you see when you leave for work. If your current door is dented, rusted, or simply outdated, it is dragging down the value of your entire property.

Whether you own a colonial townhouse in Alexandria or a modern estate in Potomac, we help you select the perfect architectural match. Serving Montgomery County, Northern Virginia, and D.C., we are authorized dealers for the industry’s top brands, bringing you factory-direct pricing on the most durable, energy-efficient doors available.

Transform Your Home’s Curb Appeal with a New Garage Door
Real estate agents agree: A new garage door is the fastest way to modernize a home.
The “Wow” Factor: Replacing a generic, builder-grade white door with a faux-wood Carriage House door adds instant character.
Color Matching: We offer custom color matching (including Black, Sandstone, and Walnut) to complement your siding and trim.
Window Inserts: Adding windows to the top section breaks up the “wall of steel” and lets natural light into your garage.
The #1 Home Improvement for ROI (Return on Investment)
According to the annual Cost vs. Value Report by Remodeling Magazine, garage door replacement consistently ranks as the #1 project for Return on Investment. Homeowners in the Mid-Atlantic region typically recoup 90-95% of the cost of a new door when they sell their home. Why? Because it is both a functional and an aesthetic upgrade. A new door improves security, insulation, and appearance simultaneously. It is smarter money than a kitchen remodel.

Premium Brands We Carry: Clopay, Amarr, and Wayne Dalton
We are not tied to one manufacturer. We source the best door for your specific needs.

Why Insulation Matters in the DMV (R-Value Explained)
In Maryland and Virginia, we face freezing winters and humid summers. If you have a “hollow” steel door (pan door), your garage acts as an icebox in winter and an oven in summer. We recommend upgrading to 3-Layer Sandwich Construction (Steel + Insulation + Steel).
Polystyrene vs. Polyurethane: We install doors with Polyurethane foam injected into the core. This bonds to the steel walls, making the door dent-resistant and providing R-Values up to 18.4.
The Result: A warmer garage, lower energy bills (especially if you have a room above the garage), and a door that operates quietly and solidly.
Our 5-Step "White Glove" Installation Process
Buying a door is easy; installing it correctly is the hard part.
Free Consultation: We measure your opening (width, height, headroom, backroom) to the inch. We bring color chips and brochures so you can see the options in your driveway.
Order & Delivery: We track your order from the factory. Once it arrives at our warehouse, we inspect it for shipping damage.
Removal & Disposal: On install day, we remove your old door, tracks, and hardware. We haul it all away for recycling; you don’t lift a finger.
Professional Install: We install new heavy-duty tracks, high-cycle springs (calibrated to the new door’s weight), and new weather stripping.
Final Walkthrough: We demonstrate the safety features, show you how to lubricate the door, and hand you the warranty paperwork.

Frequently Asked Questions About New Doors
How much does a new garage door cost installed?
Prices vary widely by size, style, and insulation.
Non-Insulated Single Car Door: $800 – $1,200
Insulated Double Car Door (16×7): $1,800 – $3,500
Custom Wood/Glass: $5,000+ We provide exact, written estimates after measuring your home.
How long does it take to get my new door?
Standard white raised-panel doors are often in stock and can be installed within 2-3 days. Custom colors or Carriage House styles typically take 2-4 weeks to order from the factory.
Do I need to replace the tracks when I get a new door?
Yes. We always replace the tracks. Your old tracks may be rusted, bent, or incompatible with the thickness of the new door. A new door deserves a new foundation to ensure the warranty is valid.
Can you match the color of my front door?
Yes. Brands like Clopay offer “Color Blast” custom paint matching (Sherwin-Williams codes). Or we can order a factory finish, such as “Ultra-Grain,” that mimics the look of stained oak, walnut, or cherry.
What is the difference between R-Value and U-Factor?
R-Value measures resistance to heat flow (higher is better). For a garage door in MD/VA, we recommend an R-Value of at least 12. This keeps your garage roughly 10-20 degrees warmer in winter than the outside air.
