"I originally hired Wally to replace two support beams that span a bilco opening on my 200+ year old stone house. The job was very delicate because temporary supports had to be installed before the original log beams could be removed. I had visions of my entire 3-story stone wall collapsing, but once I saw how meticulously his crew worked and the incredible results I knew that it had been done right. Once I realized Wally’s ability, I quickly hired him to do other repairs which included: -Replacing a beam in the basement -Thorosealing the stone foundation wall in the basement -Replacing two concrete pads on my sidewalk that were cracked -Fixing a 3’x3’ sink hole in my driveway -Pour a concrete pad for my Generac generator to sit on -Filling in an old vent hole and landscaping to ensure that the ground next to the house slopes away from the house When it comes to your home, there is little that Wally and his team can’t do. I give Manfredia's Carpentry my highest recommendation."

"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."

"Fantastically well. The quality of the work performed was top notch and the individuals on the team were highly professional and very personable. The lead, Samuel Nelson, listened carefully to everything that I said and then provided valuable feedback that resulted in a better outcome and lower overall cost. I am more than pleased to be able to recommend Nelson General Contractor."

"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!"

"Adding space to our home felt overwhelming at first. This was not just cosmetic work?it involved structural changes, inspections, and multiple stages of construction. We needed a team we could truly trust. BMR BelMax Remodeling handled everything with professionalism and steady communication. Even during the more complex phases, we felt informed and confident that things were moving in the right direction. The finished addition blends perfectly with the existing house?it does not feel like something that was ?added on.? It feels natural, like it has always been part of our home. The extra space has completely changed how we live day to day, and we?re grateful for the care and effort they put into making it happen."

"We worked with Gary at Legacy Construction Company to replace the rear roof and siding on our upper floor, along with two windows, and are very pleased with the work he and his team did. Gary took time to explain the pros and cons of our options, provided siding samples and was communicative and responsive. The invoicing and payment schedule was straightforward and easy to use. The work is high quality (having survived multiple rainstorm and snowstorms at this point!), and the team was able to do it in a day once all the materials were ready, making our lives much easier. The adage “you get what you pay for” holds true; Legacy Construction was worth every penny and we are considering them for future renovations."

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 Havertown, 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.
