Customizable Exterior Doors for Your Home

Customization is at the heart of our approach. We guide you through design choices that affect energy efficiency, security, and overall appearance—from door style and panel configuration to glass type, insulation, and hardware finishes. Our four-step process keeps projects on track and ensures a precise fit for every replacement or new installation.

Step 1: Measure, Design, and Material Selection

Successful replacements start with precise measurements and thoughtful design. We employ professional measurement techniques and digital renderings to confirm opening dimensions, swing direction, and integration with sidelights or transoms. Material selection—fiberglass, steel, or wood—balances aesthetics, durability, and maintenance requirements. We also help you align hardware options (handles, locks, hinges) with your home’s security needs and style preferences.

Step 2: Remove Old Door and Prep

Removal is performed with care to preserve surrounding trim and framing. Our team assesses the existing structure for any rot, settlement, or damage and executes necessary reinforcement. Prep work includes ensuring a level sill, proper shimming, and preparing the opening for the new door system to achieve an airtight, weather-tight seal.

Step 3: Install, Seal, and Test Performance

Installation follows best practices for weather barriers, flashing, and interior finishing. We perform meticulous sealing to minimize air leakage and maximize energy efficiency. After installation, we test operation—checking smoothness of operation, seal integrity, and hardware function—while validating performance metrics such as air infiltration and water resistance through standard testing procedures.

Step 4: Finishing Touches and Maintenance

Finishing touches include re-sealing trim, addressing any touch-up staining or painting, and providing maintenance guidance to extend life and preserve appearance. We offer clear warranty information and optional service plans that cover periodic inspections, hinge or weatherstrip replacements, and expedited support should issues arise.
