is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"I had an old refrigerator, microwave and some other things to be removed from my backyard. Robert was the original guy I I contacted. We talked pricing and then arranged a Time for pickup. Vinny was the worker that came out on time I may add he introduced himself and got straight to work it took him about not even 15 minutes to get all the stuff on the trailer. We talked for a bit and he informed me that they were a construction company that also did repairs and to keep them in mind if I ever needed anything which I will I've added them to my contact list. I think Robert and Vinny are phenomenal guys. They were both professional and friendly at the same time. I gave them five stars but that really not enough to describe how they made me feel like a special and valued customer. So this is my personal rating; 🌟🌟🌟🌟🌟🌟🌟🌟🌟🌟Satisfaction! πŸ€—πŸ€—πŸ€—πŸ€—πŸ€— Friendliness! πŸ‘πŸΌπŸ‘πŸ»πŸ‘πŸ‘πŸΎπŸ‘πŸ½πŸ‘πŸΏ Getting the job done! "

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.
