Home Additions & Extensions in Arlington, TX | API Contracting & Remodeling
More Space, Built to the Highest Standard
More Space, Built to the Highest Standard
Your home should grow with you — but finding the space to do that isn’t always simple. Whether you need an extra bedroom for a growing family, a dedicated home office, a sunroom, or a full second-story addition, the right contractor makes all the difference between a seamless expansion and a costly headache.
At API Contracting & Remodeling, we specialize in home additions throughout Arlington, TX and the surrounding DFW area — including Fort Worth, Mansfield, and Dallas. Our team brings the same exacting craftsmanship standards to every addition we build, from the foundation work to the final coat of paint. And because the finished space should be truly ready to use from day one, we complete every project to professional Make Ready cleaning standards — so your new addition is clean, polished, and move-in ready when we hand over the keys.
We don’t treat additions as an afterthought. Every project is designed and constructed to feel like it was always part of your home — matching materials, finishes, and flow so the new space integrates naturally with the old.
Our Additions & Extensions Process
Adding onto a home is one of the most complex projects in residential construction. Our process is built to protect your investment, minimize disruption, and deliver results you’ll be proud of for decades.
Step 1: In-Home Consultation & Vision Assessment
We start by meeting with you at your home to understand exactly what you need and how you live. We’ll assess the existing structure, discuss your goals and budget, and help you think through options you may not have considered — whether that’s a single-room bump-out or a full second-story addition in Arlington or the greater North Texas area.
Step 2: Design, Drawings & Permitting
We handle the architectural drawings and submit all required permits with the City of Arlington and surrounding municipalities. This step is critical — proper permitting protects your home’s value and ensures the work is inspected and code-compliant. We navigate this process for you so nothing gets missed.
Step 3: Structural & Foundation Work
Depending on the scope, additions require foundational work, framing, and structural integration with your existing home. Our crew builds to last — we don’t cut corners on the bones of a project, because that’s where the integrity of the entire addition lives.
Step 4: Mechanical, Electrical & Insulation Rough-In
Before walls close up, we coordinate all plumbing, HVAC, and electrical rough-in work with licensed subcontractors we trust. Proper insulation is installed to DFW climate standards so your new space is energy-efficient year-round — especially important during North Texas summers.
Step 5: Interior Finishing to Premier Standards
This is where API’s craftsmanship truly sets the work apart. We apply our signature Level 5 drywall finish — the highest quality standard in the industry — across all new walls and ceilings. Custom cabinetry, trim, flooring, and paint are completed with precision. Your addition won’t just function well; it will look like it belongs. Once finishing work is complete, we perform a thorough Make Ready cleaning of the entire addition — removing all construction dust, debris, and residue — so the space is genuinely ready to furnish and enjoy, not just visually finished.
Why Choose API for Your Home Addition
Level 5 Drywall Finish — Because Finish Quality Is Never Optional
Most contractors stop at a Level 4 finish and call it done. API applies a full Level 5 drywall finish on every addition we complete — the highest quality standard available — resulting in walls and ceilings with a perfectly smooth, paint-ready surface that holds up flawlessly under any lighting condition.
Premier North Texas Craftsmanship on Every Project
We hold our work to a standard, not a schedule. Every detail — from framing tolerances to trim joinery to cabinet installation — is executed with the precision you’d expect from a contractor who puts their name on the work. That commitment extends to how we leave your home: every project is completed to professional Make Ready cleaning standards, so the finished space reflects the same level of care as the construction itself. Our reputation in Arlington and across the DFW metroplex is built project by project.
Local Expertise Across Arlington, Fort Worth & the DFW Area
We know North Texas building codes, permitting offices, soil conditions, and climate demands.
