"If you have a home project, go ahead and get as many bids as you want, but you need to hire 5 Quarter Construction. the owner, Walker, was always on time. The restoration of my 2 bathrooms and the garage was completed to my satisfaction. Walker was always on time, no delays, great communication, quality work. I hope I don't have another broken sewage pipe in my house, but if I do, I would hire 5 Quarter Construction again without any hesitation. 5 Quarter Construction gets a 5 star rating from me. Thank you Walker!"

"Rob and Aiden helped us with the build out of a rental unit. The amount of work that they did in one week was far beyond what we had anticipated they would be able to accomplish, and would have taken us 5-6 weeks on our own, at least. We're so grateful for the work they did for us as it alleviated a lot of stress and their quality of work is great."

"Rafael and his crew were amazing to work with. The initial visiting for a quote was free and very informative. He was quick to understand my sketches for a totally different deck design, asked really helpful questions, and gave clear recommendations. They were able to start promptly. All of the crew members were very professional in their communication and planning and updates. They were highly skilled and did excellent quality work. I am so happy with my new deck! When work was done, they honored their quoted price. For my project they did not ask for any payment upfront, just payment in full upon completion to my satisfaction. They do take other payment methods but prefer cash so I suggest you ask about your payment options upfront. For the whole process, this company was great to work with. The craftsman of the finished work was excellent quality. I recommend them to everyone."

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.
