"I am so happy that we found Krain Construction. Brian and his crew really brought our vision to life. We wanted to build 2 stories on top of an already existing foundation that only had a roof on it. We had a hard time finding someone to do it but Brian had no hesitation. He drew up a floor plan and we loved it. His crew built the new frame for our house, did the siding, doors, windows, decks, gutters, hvac. My husband and I are going to do the interior part of the house. If we had any issues we could easily text Brian and he would resolve them quickly. If we had any last minute changes, he would work with us. Very personable and professional. If we ever needed anything else done I would use them again and I would recommend to anyone needing a remodel. I will post some pictures of how our house started and how it is now that they’re done."

"Crews worked almost three full days with only short lunch breaks. Shed looks like brand new and repairs were a lot cheaper than having to demolish, add foundation and new shed. Garage door framing looks great with new recently installed garage doors. Crew let us know when they would arrive each day and were prompt and they did great job of cleaning up. Foreman, Mo, was excellent communicator. Very pleased and would highly recommend. Thank you to Doug and all the workers!"

"Rough Diamond Construction Company did an excellent job remodeling my family room/basement. Nate's attention to detail and his expertise was well worth every dollar paid. He was always in contact with me as well as advocating for me when I had a water problem in my basement with the company who initially made the repair. Because of the water problem I experienced in the summer, I decided to have the entire room renovated - new floors, walls, ceiling, doors, etc. Nate and his crew were professional and efficient. The end result is that the room is absolutely beautiful. I would recommend Nate and his team to anyone - you won't be sorry."

"I originally had C & C completed a roof replacement and siding with soffit replacement. Calvin & Chris were great to work with. They communicated clearly when they would be able to start our project, arrived on time, was very respectful of our home, answered any questions, explained what to expect for the current day and the following day prior to leaving for the evening. I used them again when I needed my bathroom remodeled and would use them again and again should I need a home improvement project. I appreciate their responsiveness and professionalism."

"We had contracted Anthony and team to update our foyer and living space in our recently purchased home. This included creating an opening and adding support in a load bearing wall, demolishing an existing closet, creating a new partition walls and bulkhead, installing new hardwood flooring and baseboards in three rooms. Communication with Anthony throughout the project was a breeze; he is extremely responsive. Once the project started, they were able to complete the work in the time that they promised. They took the necessary precautions to protect the floors and the walls during demolition and left the space neat once the work was done. There was a slight miscommunication regarding the specification of the bulkhead. But Anthony was nice enough to rectify the problem and did not charge me extra for it! I have other work planned in the future and will definitely reach out to A&J Contracting!"

"Eric and his crew did an outstanding job on the addition to our home. From start to finish, their professionalism and attention to detail were exceptional. The craftsmanship is truly beautiful, and you can tell they take great pride in their work. I’ll admit, I’m not always the easiest person to please because I have high expectations—but Eric and his team exceeded them. They listened carefully to what I wanted and delivered exactly what I asked for, and more. We are absolutely thrilled with the finished result. If you’re looking for a contractor who is meticulous, reliable, and committed to doing things the right way, I highly recommend Eric and his crew."

"This was the second time I have remodeled a bathroom and Heldt construction company did an amazing job. On the initial consult, they took the time to discuss all of the possible options for the remodel. They brought some ideas that we hadn’t thought about that were super helpful. They were a great sounding board throughout the process that helped define our ideas. We really appreciated the attention to detail. I love showing off the finished product every time someone comes over. Highly recommend!"

"Found them to be very accommodating. They explained everything : 1) if there was a revision they explained why they needed to do it; 2) were patient in answering all my questions - even when I did not understand and they had to re-explain."

FAQs for addition to existing structure building service projects in West Mifflin, PA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
