"I recently hired Pinestate Handyman to paint three bedrooms in my home, and I couldn’t be more pleased with the results. From start to finish, he was punctual, professional, and extremely detail-oriented. The quality of the work is outstanding—crisp lines, smooth finishes, and a clean workspace throughout the entire project. He completed the job on time and exceeded my expectations. I highly recommend Chris for any painting or home improvement needs. I’ll definitely be calling him again for future projects!"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
