"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."

"We had a large amount of damage from a fallen tree on our detached garage related to a storm - clearly an emergent situation, where time was of the essence. I contacted Doug's company, and not only did he return my call promptly (a rarity in and of itself), he was at my house assessing the job the following morning. He is knowledgeable, professional, polite and extremely thorough. He got me a bid within 48 hours, which was remarkable compared to the turnaround from other firms, and which was also very helpful when dealing with the insurance company, as this was an unforeseen insurance claim related to a weather event - the price of the bid was very competitive and fair. Ultimately, we had to go with the firm that the insurance company was recommending, so our hands were tied - but I would certainly have felt more than comfortable having Doug's company complete this job. He is now at the top of my list for any future general construction work that I may need done at my property. You won't regret contacting Furko Construction for your job."

"Shane and his team were reliable and professional. They did excellent work and were better priced than all competitors. The job involved removing an old, failed retaining wall and building a new one with steps. They also installed proper drainage to secure the hillside from future shifting. We won't hesitate to hire him again!"

"I recently had my bathroom completely transformed by Brody and his crew, and I could not be happier with the results. From the initial consultation to the final walk-through, their professionalism and attention to detail were outstanding. They listened to my vision and brought it to life with stunning tile work, modern fixtures, and impeccable craftsmanship. The project was completed on time and within budget, which was a pleasant surprise given the quality of work. The team was courteous, clean, and communicative throughout the entire process. My bathroom now feels like a spa retreat, and I have Brody?s Services to thank for that. Highly recommend for anyone looking to elevate their bathroom experience."

"The owners (Chris and Cal) did an excellent job on our remodeled project. They were personally involved with the project and worked directly with us during the entire planning and implementation of the work. They were true craftsmen. We wanted a contractor who could do the entire project and C&C fit the bill. They performed the drywall, flooring, windows, painting, electrical, and structural part of the job. We would highly recommend them ."

Customers say: Quick response

"We hired Anthony to perform a bathroom and basement remodel. I can't say enough about how pleased we are in every aspect of Anthony and Mark's work, cost and professionalism. The communication and reliability was always timely, thorough and just excellent, which are things that lack in a lot of contractors we have dealt with in the past. Although we had many challenges during the job, Anthony handled them all with flexibility. It was a true collaboration from beginning to end. Not only was he easy to deal with, but the work was done way above our expectations with a focus on attention to detail. He also made sure everything was cleaned up at the end of every day, even if I said not to worry about it. Overall, these guys went the extra mile and made a difficult job enjoyable for us. We will be coming back to A&J for any plumbing or remodeling needs in the future."

"I hired Mangone Construction after a neighbor used them for a project. The Company has completed 2 projects to date on my property: 1) 2nd Floor addition over a first floor structure and 2) a new rear deck including adding a roof over part of the deck. Thw owner's sons are the ones that perform the work. They're diligent, clean, hardworking and meticulous. They're open about necessary project changes with overall impacts to the final product."

FAQs for addition to existing structure building service projects in Oakmont, 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.
