Glass Selection
Every door we install can be configured with the glass type that matches your priorities -- whether that is maximum clarity, energy savings, privacy, or security.

Door Hardware
The hardware on your glass door affects its security, durability, and daily feel. We install commercial-grade hardware from leading manufacturers on every project.
Lever handles, pull bars, and ergonomic grips in brushed nickel, matte black, oil-rubbed bronze, and satin chrome.
Multi-point locking systems, smart locks with keypad and app control, deadbolts, and hook locks. Keyed alike options for multiple doors across your property.
Surface-mounted and concealed overhead closers with adjustable closing speed and latching force.
Ball-bearing hinges, spring hinges, concealed hinges, floor springs, and pivot sets.
Energy Performance
Modern glass doors can be remarkably energy efficient. We install ENERGY STAR certified systems and help you understand the ratings that matter most for the DMV climate.
Measures how well a door prevents heat from escaping. ENERGY STAR doors in our climate zone require a U-factor of 0.30 or less.
Lower is better
Solar Heat Gain Coefficient measures how much solar radiation passes through. ENERGY STAR requires 0.25 or less for the DMV region.
Lower reduces cooling costs
Thermal breaks in aluminum frames and multi-chamber vinyl profiles prevent heat transfer through the frame itself, eliminating cold spots and condensation.
Eliminates thermal bridging
We install doors that meet or exceed ENERGY STAR requirements for the Northern climate zone. Certified products may qualify for federal and local utility rebates.

Expertise Across Sectors
We bring the same level of craftsmanship to a 10-foot pivot entry in Great Falls as we do to a storefront vestibule on K Street. Here is how the two worlds differ.

Safety & Security
Modern glass doors are far more secure than many homeowners realize. We install doors with advanced locking, impact-resistant glazing, and smart access control.
Locking bolts engage at multiple points along the door frame -- top, bottom, and sides -- for significantly stronger resistance to forced entry than.
Tempered glass is four times stronger than standard glass and breaks into safe pebbles.
Modern glass doors pair with smart lock systems offering keyless entry, remote access control, activity logging, and integration with home automation platforms.
How We Work
A clear four-step process with no surprises. We measure twice, communicate at every stage, and leave your property cleaner than we found it.
We discuss your vision, evaluate your space requirements, and explore door styles, glass options, and frame materials suited to your property.
Our technician visits your property to take precise measurements of the opening, assess structural conditions, and confirm the ideal door configuration.
Based on measurements and your preferences, we present a detailed proposal covering the door system, glass type, hardware, and a transparent written estimate.
Our experienced installers handle everything -- removal, framing prep, door installation, hardware mounting, weathersealing,
Frequently Asked Questions
Answers to the most common questions our customers ask about glass door installation, repair, and replacement in the DC, Virginia, and Maryland area.
Most residential glass door installations are completed in a single day. Sliding patio doors and French doors typically take 4 to 6 hours including removal of the old door, framing preparation, installation, hardware mounting, and weathersealing. Larger projects like multi-panel bi-fold systems or commercial storefront entries may require two days. We provide a specific timeline estimate during your consultation.
Yes. If your door frame and hardware are in good condition, we can replace just the glass panel. This is common for foggy insulated glass units, cracked patio door glass, and broken sidelites. Glass-only replacement is faster and more cost-effective than full door replacement. We carry standard sizes on our trucks for same-day service on many common door glass replacements.
Triple-pane insulated glass with dual Low-E coatings, argon gas fill, and warm-edge spacers delivers the best energy performance. For our DMV climate zone, look for doors with a U-factor of 0.25 or lower and an SHGC of 0.25 or lower. We install ENERGY STAR certified door systems from major manufacturers that meet or exceed these requirements.
Absolutely. Modern glass doors use tempered or laminated safety glass that is extremely difficult to breach. Multi-point locking systems engage at three or more points along the frame. Impact-rated laminated glass holds together even when struck with force, preventing pass-through entry. We also install security film, smart locks, and alarm sensor integration for additional protection.
Yes. We offer two approaches: replacing a glass panel with a new panel that has a built-in pet flap, or installing a pet door insert into a sliding patio door track. Both options accommodate dogs and cats of all sizes. The pet flaps include magnetic closures and weatherstripping for energy efficiency, and locking mechanisms for security when not in use.
Sliding doors operate on a horizontal track and do not swing into the room, making them ideal for tight spaces and decks with limited clearance. French doors are hinged and swing open, creating a wider unobstructed opening when both panels are open. French doors have a more traditional aesthetic with divided lites, while sliding doors maximize glass area for unobstructed views.
Bi-fold doors consist of multiple glass panels connected by hinges. When opened, the panels fold against each other like an accordion and stack neatly to one side, creating a wide opening that merges indoor and outdoor living spaces. Our bi-fold systems operate on a top-hung track with a flush floor sill. They can span openings up to 24 feet wide.
In most cases, yes. Pivot doors require reinforced floor and header connections for the pivot hardware, but they do not need traditional side jamb hinges. We assess your existing opening and structural conditions during the site visit. Some openings may need minor modifications to accommodate the pivot mechanism and the larger panel dimensions.
Yes. We install and repair commercial glass entry systems including single and double storefront doors, automatic sliding doors, revolving door glass, and vestibule entry systems. Our commercial work includes ADA-compliant configurations, panic hardware, automatic door operators, and security glazing. We serve retail, office, restaurant, and hospitality properties throughout the DMV.
Our installations carry a workmanship warranty covering the installation labor, weathersealing, and hardware mounting. The glass and door components carry separate manufacturer warranties that typically range from 10 years to lifetime depending on the product. We provide all warranty documentation at project completion and handle warranty claims on your behalf if any issues arise.
Yes. We provide same-day emergency service for broken or shattered glass doors. If your door glass breaks after hours, we can board up the opening immediately and return the next business day with the replacement glass. For storefront break-ins and security breaches, we offer rapid-response temporary glazing to secure the premises.
Clean the glass with a mild glass cleaner and soft cloth every few weeks. Vacuum and wipe down the tracks on sliding doors monthly to prevent debris buildup. Lubricate the track with silicone spray twice a year. Inspect weatherstripping annually and replace it when it becomes compressed or cracked. Check hardware screws and adjust the roller height on sliding doors if the door becomes difficult to operate.
