OUR ROOM ADDITION PROCESS
At C&S Remodeling, we follow a structured, thorough process to ensure your room addition is designed and built to the highest standards. Our approach minimizes disruption to your daily life while delivering exceptional results.
CONSULTATION & DESIGN
We begin with an in-home consultation to understand your vision, needs, and budget. Our design team works closely with you to create detailed plans that integrate seamlessly with your existing home. Multiple design revisions ensure your complete satisfaction.
PERMITS & PREPARATION
Our team handles all permitting requirements with local authorities. During this phase, we finalize material selections, order supplies, and prepare a detailed construction timeline. We also establish containment strategies to minimize disruption to your living space.
CONSTRUCTION
Construction begins with site preparation and foundation work. Our skilled craftsmen follow the detailed plans, with our project manager overseeing quality control at every stage. Regular progress updates keep you informed throughout the building process.
FINISHING & INSPECTION
After construction is complete, we focus on finishing details, cleanup, and final inspections. A thorough walkthrough with you ensures every aspect meets our high standards. We don't consider the project complete until you're 100% satisfied with your new space.
TYPICAL PROJECT TIMELINE
DESIGN & PLANNING PHASE
2-4 weeks: Initial consultation, design development, material selection, and proposal preparation. This phase is critical for ensuring your addition meets your needs and integrates perfectly with your existing home.

FREQUENTLY ASKED QUESTIONS
How much does a room addition cost in San Antonio?
Room addition costs in San Antonio typically range from $200-$450 per square foot depending on the type, complexity, and finishes. A basic 200 sq ft bedroom addition might start around $40,000, while a luxury master suite could exceed $100,000. Factors affecting cost include foundation work, roofing modifications, electrical/plumbing requirements, and material quality. During your consultation, we provide a detailed estimate based on your specific project.
How long does a typical room addition take to complete?
Most room additions take 8-16 weeks to complete, depending on size and complexity. Simple additions like a bedroom might take 8-12 weeks, while more complex projects like master suites or kitchen extensions often require 12-16 weeks or longer. Factors affecting timeline include permitting, weather delays, material availability, and whether the addition requires extensive utility work. We provide a detailed timeline specific to your project.
Do I need permits for a room addition in San Antonio?
Yes, room additions in San Antonio require building permits. Depending on the project, you may need multiple permits for structural changes, electrical, plumbing, and HVAC work. As a professional remodeling company, C&S Remodeling handles all permitting requirements for you, including documentation preparation, submission, and inspections coordination. Our familiarity with local building codes ensures your addition will meet all requirements.
Will a room addition add value to my home?
Yes, well-designed room additions typically add significant value to your home. According to recent data, homeowners in San Antonio can expect to recoup approximately 60-75% of their investment in terms of increased property value. Some additions, like master suites or family rooms, tend to offer better returns than specialized spaces. The value added depends on design quality, construction standards, and how well the addition integrates with your existing home.
Can I stay in my home during the construction?
Yes, most homeowners remain in their homes during room addition projects. Since additions are typically built onto the exterior of your home, disruption to your living spaces can be minimized. We establish containment barriers between construction zones and living areas, maintain clean worksites, and schedule noisy work appropriately. For certain phases that might involve significant dust, noise, or utility interruptions, we'll provide advance notice so you can make arrangements if needed.
What's the difference between a room addition and a bump-out?
A room addition is a fully new space with its own foundation, walls, and roof, typically adding substantial square footage (100+ sq ft). A bump-out is a minor extension of an existing room, usually 2-4 feet outward, without requiring a new foundation. Bump-outs are less expensive and faster to construct but provide limited additional space. Room additions offer more flexibility in design and more significant expansion of your living area, though they require more extensive construction.
