"Joe and his team listened to what we wanted and gave us exactly what we were looking for. We wanted an addition that blended with the existing architecture so that the new portion looked like it had always been there. The carpentry work that All Phase performed was particularly impressive, showing great attention to detail and skill. Any issues that came up or changes that we requested were promptly addressed so that the project ran smoothly from start to finish. We now have an old home that fits our needs perfectly."

"Manfredia’s Carpentry completely rebuilt our enclosed front porch, and they did an excellent job. Wally and his crew did top notch work at a very fair price. Many problems arose as our house is over 100 years old, and Wally was very straightforward and financially conscientious when presenting us with solutions. The entire crew was incredibly friendly and respectful. The overall experience was wonderful, and we would absolutely hire them again in the future as well as recommend them to anyone in need of a contractor. -Bob and Debby"

"Brian was with us from start to finish with our combined garage, powder room, laundry room remodel. He has an incredible attention to detail and he really cares about the quality of his work. There are very few problems that Brian cannot solve. He is also very creative, practical and talented. He works with great subs who showed up on time and did great jobs with the remodel. He and his crew were a pleasure to work with. Thanks Brian."

"Matt and his team with MNB Renovations did a 32 x 24 addition that was basically a home build from the ground up. I am still surprised for the size of this project how stress free the process was. Matt was very detailed and checked in on everything to make sure we were getting what we wanted. In the end he asked us to make a list of anything that needed to be addressed and there was absolutely nothing to mention. They did a perfect job, the quality of the work is amazing, and the entire team was very nice, professional, and trustworthy! I absolutely recommend this company to others and will definitely use them again in the future!"

"I am beyond satisfied with the work done by Inspired Exteriors. The craftmanship was excellent and the porch stair railings almost perfectly match my existing porch railings. Workers were neat and professional and worked a long day to get the job done. I thought the price was right and was a great value for the amount of work that went into the project. I worked personally with the owner who was very professional and spent a lot of time with me even though it was a relatively small project."

"Gary and his team gutted and expanded bathrooms, installed wood floors, installed smart toilets, replaced countertops, kitchen sinks, electrical work, installed a whole house generator, installed ductless systems in areas of the house that needed additional heating /AC as well as replaced a few windows. Gary and his team were attentive to detail and open to suggestions and they all were friendly, efficient and good natured which is truly necessary on extended projects like ours."

"I had a tree fall on my house back in June 2020 which caused major damage to the back of my home. I called several contractor's but I wasn't pleased with their assessment. I then came across Legacy Construction and they were great from the start. I spoke to Mrs. Diane on the phone and she was great, she gathered a lot of information from me and told me that I was in good hands and informed me that Gary the project manager will be contacting me shortly. After speaking to Gary he explained to me the first thing that needed to be done is the property needed to be tarped asap because the home is being exposed to water which is causing further damage and causing mold to building up because water has been coming into the property for almost two months. Gary informed me step by step room by room what damages the tree caused and how he was going to fix the water damages and the damages done to the frame of the home. After speaking to Gary I was sold and stopped looking for a contractor to fix my house. I would definitely recommend Legacy Construction to anybody that needs work done to their home. Their customer service and workmanship is great I would highly recommend."

"The garage was crushed by a huge tree, so we needed demolition, debris removal, and a new garage, plus other storm damage repairs. We contacted several contractors, and D.Willis was among the first to arrive, and offered the widest scope of skills for the job, including handling permits -- one contractor who could do everything for the work. They brought in an excellent team of builders who worked efficiently together. As new damages were discovered during repairs, they were amenable to take on the additional work and renegotiate the contract as needed. Finally, the work completed a bit beyond the contracted terms, with good attention to details."

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