"Mathew did an outstanding job on the porch. I couldn’t be happier. I was really scared that the stone needed wasn’t going to be found. Mathew took the time to find the right stone. There was also a delay due to weather and he stayed communicated. He was also honest with the materials and let me keep what was left of the stone. I was impressed with his craftsmanship and the completion of the job by himself. Usually this type of job other companies need 2-3 people.Overall very professional. I look forward to using Mathew in future home projects."

We are fast, reliable, creative, affordable with 20 years experience. We are veteran and family owned with the expectation of our customer satisfaction as a priority. We offer Veteran, Teacher, First Responder Discount

"I had a leak in my roof and it was assessed and repaired for $750 with a 3 year warranty. The roof assessment was wrong and the roof still leaked. They then offered to come back and fix the real problem associated with solar panel installation for $2,800- $3,000. They basically fixed a section of my roof that wasn't leaking, so I threw my money away. They claimed the $2800-$3800 included a discount based on my prior service but I've since had a cheaper quote. Honestly, I thought the warranty I paid for gave me peace of mind but technically their repair didn't fail. It was never the actual problem. Very disappointed with this company."

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.
