Betterliving Patio and Sunrooms provides a variety of general contracting services for residential clients throughout the Greater Pittsburgh Area. Betterliving specializing in three and four season sunrooms, screen rooms, patios and decks, as well as, windows and doors. Owner and operator Raymond Hepp believes that one of the biggest advantages of Betterliving is its ability to combine highly competitive pricing with first-rate service. Ray started Betterliving Patio and Sunrooms in 1999 after years of selling sunrooms for another company. He decided it was time for him to branch out on his own. He believes in providing the customer with affordable, quality products and materials made and manufactured in the USA. Betterliving is exclusive and the quality, local manufactured products cannot be bought anywhere else. Parts and products are constantly being scrutinized for the best technology and quality available. Ray believes in using only the best quality for his customers. He never compromises on the quality of products and services. Maintaining customer satisfaction is a crucial aspect of Betterliving Patio and Sunrooms. We are known for effectively communicating with our clients throughout every step of their construction projects and realize it is crucial to make sure every job is completed to the customer’s satisfaction. We stay in contact with our clients before, during and after their projects so we can confirm they’re happy with our work and the final result.

"Ray and the entire team were excellent! I had previously received an estimate from another company, but they used subcontractors for the actual work and this concerned me. Another company came out and took measurements, but never gave me an estimate. I got the feeling the job was too big for them. I was now really hesitant to trust anyone to do the work and wanted to make sure they were going to do it right. I went to the BBB and found Betterliving with an A+ rating. From the beginning, I felt comfortable. They explained everything, were more than open to additional phone calls to clarify any questions I had and gave me an estimate very quickly. While I knew the work would not be started for several months, I received weekly phone calls from Michele, so I felt informed the whole time. They even took care of the permit that was required, so I didn't have to do any paperwork, handle the fee or answer questions. Mike was great about getting the measurements and he let me know the work would not start until he made sure all of the pieces were available. Frank was super with the installation. He treated the entire project as if he were working on his own home. The payments were done over the duration of the project, so I didn't feel like I was handing over my money without anything in return. And the final payment was not due until I was satisfied with the work completed. The warranty provided on the materials was excellent. I'm happy I decided on Betterliving and have been enjoying my patio cover every chance I get! A long time dream is finally a reality."

We specialize in creating custom cabinet and countertop solutions for your kitchen, bath or any other part of your home.

"I started working with Jim Seibert of Trademark Cabinet Company this summer in preparation for a significant kitchen overhaul in my townhouse. From the beginning, he was open to my questions and preferences, and helped me plan and design cabinets to fit in the existing footprint but far surpassed the functionality of my 1980s cabinets. When it came time to do the demo in October, he and his crew were both friendly and professional, and cleaned up after themselves. I watched them repeatedly do calm and focused problem-solving on the fly, and they finished earlier than we expected. Then when they brought the gorgeous cabinets we chose, they were meticulous in their installation and gracious as I watched the whole process from my spot on the stairs. The finished product was superb, the price very competitive, and I only have compliments for their work."

FAQs for second story addition building service projects in Mars, PA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
