Types of doors
Homeowners across Maryland have different needs, so we offer options that fit your house, lifestyle, and budget.
- Entry doors, including front entry doors, focus on protection at the main entryway while enhancing curb appeal.
- Patio doors balance open views with privacy and security, so your patio becomes a safer, more enjoyable space.
- Storm doors add a tough outer layer that helps block wind and rain, reduce drafts, and extend the life of primary exterior doors.
You can choose contemporary or classic elegance in several finishes, colors, and glass options to match your home.
Entry door security
Entry door security starts with solid construction, quality locks, and reinforced frames that resist forced entry. Steel or fiberglass-clad entry doors deliver excellent durability and protection, and many models are designed for energy efficiency that can help lower heating and cooling costs. For a clean look, front entry doors can be painted to match your trim or to create a bold focal point at the entryway. If you prefer more light, choose styles with security-rated glass and internal grilles that protect without sacrificing beauty.
Door replacement
If your current door sticks, leaks air, or shows rust, door replacement can improve security and comfort in one project. Replacing older exterior doors with well-fitted new doors reduces drafts, makes rooms feel quieter, and can enhance curb appeal for potential buyers. Our team follows a patient and thorough approach from consultation to final walkthrough, so customers know what to expect at every step.
Security door materials
Steel doors
Steel doors are popular for Baltimore properties because they combine strength, value, and low upkeep. Many steel models include insulated cores for energy efficiency, multi-point locks for enhanced security, and rigid frames that help protect against intruders. With several finishes and styles, steel can suit traditional rowhomes and contemporary houses alike.
Fiberglass doors
Fiberglass offers durable performance with realistic woodgrain textures and a lighter weight. They’re a great fit when you want the look of wood with less maintenance. High-quality fiberglass entry doors resist dents and corrosion, are designed to handle busy entryways, and can be factory stained or painted.
Energy efficiency
Efficient doors help reduce energy use and improve comfort. The U.S. Department of Energy advises checking the National Fenestration Rating Council label for U-factor and solar heat gain coefficient to compare performance among doors and windows. Lower U-factors generally mean better insulation, which supports energy efficiency and a quieter room. Pairing energy smart doors with well sealed frames and storm doors can further reduce drafts and help protect the primary door from the elements.
Patio and storm doors
Patio doors should open smoothly, lock securely, and protect your views. Look for multi point locking, tempered glass, and designs that balance privacy with daylight. Storm doors provide an extra barrier against wind, rain, and debris, and many include screens for seasonal ventilation. Baltimore weather can be unpredictable, so storm doors help protect exterior doors, cut wear on finishes, and extend service life. Well-fitted storm doors can also enhance energy efficiency by reducing air leakage around the entryway, which supports comfort and peace of mind in all seasons.
Cost benefits you should know
Pricing in Maryland depends on material, size, features, and local labor costs. Current national data shows most homeowners spend about $560 to $2,900 total, with an average near $1,190 for a security door. Typical professional labor runs about $200 to $650 of that price, depending on the job scope and site conditions. Your final costs may vary in Baltimore based on material upgrades, custom sizes, security hardware, and whether structural carpentry is required.
Professional installation
Correct install is essential for security, weather sealing, and smooth operation. At Master Seal, our installers square and shim the frame, anchor the hinges to structure, seal gaps to reduce drafts, and confirm that locks engage cleanly. The result is a secure door that looks great and performs as designed.
