Customers say: Super punctual

"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."

"I hired to Josh to work that includes replacing the roof of my garage, clear my backyard, rebuild my backyard fence, my patio area, my bathroom, my front porch, replace windows, and doors. Josh always does amazing work. He is thorough, thinks outside the box, and is always upfront, honest, and professional. Never rude or disrespectful. He’s the ONLY ONE allowed to work on my home."

"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."

"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 hired Anthony to perform a *laundry room addition* to our house. We live in an older home and wanted to take out a 2nd floor extra storage space that we were not using and convert it into a laundry room. The price was fair but the service and work were well above average. They go above and beyond and get the job done quickly without cutting corners and fixing previous DIY improvement disasters. I could not recommend Anthony and the company more. Look no further, because this is your guy."

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."

"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 Bethel Park, 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.
