"The work was awesome, they were on time and worked every day. They cleaned up after their day was complete and were extremely easy to work with through the process. Their workmanship is top notch. I will be using them again to build a barn and eventually to build an addition off the back of my house."

"Perfect! Talk about service after the sale, Manfredia Carpentry A +++. We have used this Company for over 15 years for projects ranging from commercial exterior renovation, residential - siding, addition, decks. Forgetting great craftsmanship and fair prices, anytime we have needed anything AFTER a project is over, Manfredia has been superb. Nice to see that craftsmanship and service after the sale still exists. Thanks Manfredia Carpentry & General Contracting."

"Over the course of the last six months, Brian and his team competed several large projects for us including a covered front porch, paver driveway, cement walkway, and basement remodel with a full bathroom. We were extremely pleased with all of the work done and communication from Brian throughout the process. G&V does not cut any corners when competing jobs leading to high quality results and happy customers. We would highly recommend G&V and they will be our first choice when doing more work on the house in the future."

"Wonderfully. The contractor in pre-bid had great technical questions and clearly understood what had to be done to complete the design. Their price was in the middle of the three bids received and along with their clear competency presented the best value of the proposals. We were very impressed with the quality of work of their field staff and in oversight of their subcontracts (i.e. mason, roofer, electrician, plumber). We maintained good communication with their project manager for scheduling and office admin for billing/paperwork. Challenges presented in structural changes and permit delays were handled well and clearly explained in working through solutions. Their relationship with city inspectors and knowledge of the new permit process helped expedite reviews as needed. Overall the contractor worked well to overcome some of the unforeseen conditions that cropped up and adjusted to our design requirements even when outside their normal operating standards. We'd certainly re-hire this company for future jobs and have already recommended their services to other who reached out. We're very pleased with the final product and experience."

"I highly recommend Bryan's Home Improvement and Handyman Services. The owner Bryan Grubb was wonderful. He and his staff assisted me in every stage of the remodeling of my bathroom. We entered a contract which they stuck by. The price to perform the remodeling was very, very fair. During the remodeling, a structural problem was found. They addressed the problem and provided me with options to correct the problem. These were structural issues which should have been addressed by their predecessors and was inconceivable that the problem could have been missed. Bryan's handymen, led by Jorge, were professional, timely, efficient, knowledgeable, artistic and neat. They did a fantastic job on my bathroom. I can't thank them enough. I will recommend them to everyone I know. I will definitely hire them again. A+++"

"Frank and his crew completed a full primary bathroom renovation for my partner and I in April of 2023 in Manayunk. Frank was extremely communicative, and his team was respectful, timely, and diligent. He was very transparent when they discovered additional water/mold damage during demolition, and presented us multiple options in how to mitigate. We were so pleased with First Class’s work, that we intend to have them complete additional work for us in the future. We would absolutely recommend them to anyone!"

"I was very impressed with Gary and his team at Legacy Construction. He was very professional and responsive to my questions and provided knowledgeable answers. He also provided before and after pics and videos of the work in the roofs (main and sunroom) and the gutter system replacement and always kept me informed of their progress. In fact, I plan to use them again for additional home projects!"

Customers say: True professional

"Santosusso Construction did an amazing job on stepping in to save the day on a fix and flip project that was started by a previous construction company. It would have been completely understandable if Steve, the owner, would’ve opted out from doing the work. But instead, he jumped in, provided a fair price and brought only licensed and expert tradesmen onto the project to get the property sold. After experiencing his dedication to this project, and seeing first hand that he went above and beyond of what was expected, I hired him to renovate my home. Steve is very thorough, honest and was always ready to answer any questions that I had. He kept me updated daily regarding the progress of the construction and assured me that the renovation would be done on time. I would highly recommend Santosusso Construction over any other construction company in the Delaware Valley. And I will 100% be using them again in the future."

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