"I am so happy that we found Krain Construction. Brian and his crew really brought our vision to life. We wanted to build 2 stories on top of an already existing foundation that only had a roof on it. We had a hard time finding someone to do it but Brian had no hesitation. He drew up a floor plan and we loved it. His crew built the new frame for our house, did the siding, doors, windows, decks, gutters, hvac. My husband and I are going to do the interior part of the house. If we had any issues we could easily text Brian and he would resolve them quickly. If we had any last minute changes, he would work with us. Very personable and professional. If we ever needed anything else done I would use them again and I would recommend to anyone needing a remodel. I will post some pictures of how our house started and how it is now that they’re done."

"Rick and his crew were just what I was looking for. I had questions about replacing my home roof with metal and Rick answered them all along with a few suggestions that I hadn't thought of. He came to my home on the day the supplies were being delivered to be sure everything was correct and direct the driver where to put them. The workers were reliable, (at the work site at 6am everyday), friendly, and most importantly skillful. I love my new roof and have been getting calls and comments from neighbors and friends who drive by. I would surely recommend RMS Contractors to anyone looking for a new roof!"

"Brody was awesome to work with to have my bathtub and surround remodeled. From the start he was very pleasant to talk to and stayed in communication during the entire process to make sure I was aware of what was happening next. I love how the bathroom turned out and I'd highly recommend."

"The owners (Chris and Cal) did an excellent job on our remodeled project. They were personally involved with the project and worked directly with us during the entire planning and implementation of the work. They were true craftsmen. We wanted a contractor who could do the entire project and C&C fit the bill. They performed the drywall, flooring, windows, painting, electrical, and structural part of the job. We would highly recommend them ."

"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."

"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."

"This is truly an A+ company for concrete repair and we had an excellent experience from start to finish for two jobs. Patty is very professional in handling the calls to schedule appointments and answered all of my questions. Gary was very direct and honest when he looked at the problems and recommended repairs. We also appreciate that he recommended that we hire a structural engineer for some problems with the house. We had 2 contracts that were completed by Joe and his team. They did a great job sealing some significant cracks in the garage floor and then sealing the entire garage floor. It looks like new. Joe is very personable and explains the repair process at every step. We highly recommend A Plus!"

"We contacted Greg at Omnipro to have pavers added to an existing backyard patio. Greg was great to deal with and his recommendation of which pavers to select was spot on. The work was done timely & the end result exceeded our expectations. The clean up & repair of our yard was also very good. One minor post install issue. Again, Omnipro was very responsive. Highly recommend."

"This was my third time working with this contractor and each project was a pleasurable experience! As was the case with the other two, they started this project on time and finished on time! All the work was done according to strict Mount Lebanon code. They made suggestions based upon their experience i.e we wanted a six foot high shadow box fence but while Mount Lebanon code allows for a six foot high privacy fence of just about any style, they do not allow, by code, a six foot high shadowbox fence. Steve Hilpert proceeded to build us a 4 foot high shadowbox fence (the maximum height allowed by code) with a custom built 2 foot high trellis section which Mount Lebanon subsequently approved. The fence looks beautiful!
I was nervous about cutting a big hole in the wall of our addition to install the sliding glass door. Now the door looks like it has been there all along! It came out PERFECTLY!
The deck is also beautiful and solid as a rock! We had an issue with the location of our two central air conditioning units off the back of the house. The other contractors (which I found here on Angie's List as well) said they would just build over these units. Not knowing anything about central air conditioning this seemed reasonable to me. Steve was the ONLY contractor who told me that you absolutely CAN NOT block the air flow above the units! Not only that, he was honest enough to tell me that moving the units should be done by a qualified HVAC contractor. Now that is a contractor you can trust!
All work was completed on time and within budget. The same crew arrived early each day and were polite and professional. The job site was spotless at the end of each day!
If you are looking for a trustworthy, professional contractor, you can not go wrong with SC Hilpert!!!"

"We are so happy with BKG! Noelle from BKG designed our kitchen to change the layout and add a dishwasher and island that we desperately needed and wanted. We went to her after working with two other companies that weren't able to give us what we wanted in our design. Noelle was quick to answer our questions, provide the renderings, and respond to additional questions as we were ordering appliances to fit. She is the most patient person and great at problem solving! Her industry knowledge helped us to order the right size appliances so we could get everything we wanted in our kitchen, like my farmhouse sink! The install crew was fantastic too. They assembled all of our cabinets on floors that were just refinished the week before without a single scratch!"

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