"Once started the work was done quickly. The original scope of work for concrete finish was changed at my request to use exposed aggregate making the pad look like one single pour. Wow, looks great, money well spent. Gable roof with cathedral ceiling and finishes match perfectly. Looks like it has always been part of the house. Light landscaping was also provided to repair lawn from construction damage. This was done by the contractor without charge or my request. There was a small leak that the contractor repaired after several trips. This was resolved to my satisfaction. The point here is the contractor took responsibility and returned until this was resolved. We love our new patio, it’s perfect!"

"We hired Magic Designs for a 1500 sq ft home addition and couldn’t be happier. They added a stunning great room, expanded our kitchen and dining area into a spacious open floor plan, and extended our children’s bedrooms by 8 feet—giving them room to grow and thrive. The kitchen is now modern and functional, perfect for hosting and everyday life. The new garage is a dream: it easily fits our SUV with space to spare. Every detail was handled with care and precision. Magic Designs was professional, communicative, and respectful of our time and budget. Their craftsmanship and design expertise exceeded our expectations. We now have a home that feels bigger, brighter, and better suited to our family’s needs. Highly recommend Magic Designs for any major renovation—they truly live up to their name! MAGIC!"

"Solid Rock Homes & Design worked with us to design and build a kitchen in our basement. They worked within our budget and time frame to complete the exact kitchen that we desired. They were professional and knowledgeable in all stages of the project- from the detailed design of the space, to the plumbing and electrical work, then the installation of the cabinets. We highly recommend any homeowner to use them for any renovations!"

"I am so thankful that I found Brodys Services! My toilet wasnt flushing good & little moths were appearing from the drain. I had 2 plumbing companies come and each one had a different opinion and quoted high prices. My third estimate was by Brody. He was a good listener & very polite. He tested my plumbing and found the problem was a cracked pipe under the toilet. He had to jackhammer the floor, fix the pipe and re-cement the floor. He put plastic on the door ad kept the dust contained and cleaned everything when he was done. I was so pleased with his work and affordable prices, I decided to do a remodel of the bathroom. He removed my tub and installed a large shower, new vanity, toilet, and floor. It looks wonderful! He worked according to my schedule, gave me his expert opinion, and cleaned up daily. I am so happy with the results & his price. I would definitely be using his services again!"

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