"Jim and Danielle help me take a room that was old-fashioned and in need of a remodel into a space that is very warm and inviting. With his guidance on the day-to-day work and his ideas for how to design the space, he was a valuable resource for me through the process. He gave me lots of ideas and choices from flooring to fixtures. As the crews that came into the house were friendly and considerate of my privacy as I work from home. They worked hard and completed their piece of remodel as planned. I highly recommend Jim and Danielle Katz at Casade Customer Renovations, LLC. "

Mangone Contracting, is a well established company in Arnold, which serves the surrounding communities too. We offer the best in customer service, as well as, professionalism. Our company prides itself on integrity, so our work reflects that. Call us for your next project.

"This team is top notch! We contacted a few contractors and never heard back. Once we contacted Mangone Contracting, we had a meeting at our home within a day or so and drawings within 24 hours of that meeting. We had a bedroom and bathroom added to the second floor of our home and it turned out wonderfully! Another great thing is they did it for right around what the estimate was written for. (Price and timeline) The whole team was very good at meeting our requests and even came out on a weekend (within 30 minutes of contact) to fix an issue we were having with our breaker box after putting a new service in. All around great people and great at what they do!"

Home remodeling company that has myself and my help working hands on, on your projects. (not some g.c. You only see when you sign checks.) I use sub contractors to do my plumbing and electrical work. I am licenced in pa.as a contractor. My # is 055911. Each job is priced seperately. Bigger projects by contract. I can work on smaller jobs by an hourly rate usually $45.00. I carry $2,000,000 liability insurance. (that i have never used). I have never been sued or brought to court. I have alot of repeat customers which speaks for itself. I think of myself as a honest man who just wants to provide a good quality service to people who need someone they can trust with their biggest investment. Their home! I have lived in ireland england and the u.s.a. And have worked in the construction indusrty in all three countries. I have a degree in drafting helpful in instalations and design changes. I belive that the customer is always right!!! I do all and any work that comes my way. Not too proud to do small jobs. You never know where it will leadto. I fixed a leaking skylight for $150.00 and the next spring built the same customer huge wrap around deck for $20,000.00. Call 412-414-5870.

"My wife and I wanted to remove a load bearing wall in our house, and hired Bob and his crew for the job. They were absolutely exceptional from start to finish. Bob did brilliant work moving ducts and with his finishing work to make the house look as though the wall had never been there. I not only would, but I would ONLY hire Bob and his guys for any contracting work we need done in the future. I can not express how highly I recommend them."

We're a small company who specializes in bathroom remodeling. We perform complete remodels (wiring, plumbing, plaster , etc.), custom showers, custom glass enclosures, and small jobs as well. We also remodel kitchens and game rooms, and perform general interior remodeling, including structural modifications. We do not have a showroom, but rather extend our pricing at several specialized suppliers. This provides our customers with the broadest selection possible, the assistance of dedicated designers, the use of their showrooms, and great pricing. We routinely work on both older and newer homes, and welcome the challenges of unusual and custom projects.

"We had two extensive bathroom renovations done. They did a superior job. Mike Emanuel is an extremely nice guy, very professional and very knowledgeable. He is completely reliable and honest. Work was done with superior quality. Adam is an artist and perfectionist. He did fabulous work with doing marble work. We would recommend them enthusiastically and unconditionally."

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.
