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.

"We couldn't be happier with our new 4-season sunroom, and we can't say enough about the people at Better Living Patio Rooms! We've had a lot of work done at our house over the years, but the crew from Better Living stands above the rest. Once the project began, work continued - without pause - until it was completed. From Anthony in sales, Mike in project management, Michelle and Jenn in the office, and Frank and Justin (who did the work), they were professional, detail-oriented, and friendly. I highly recommend Better Living. Brian in McCandless."

"This company was awesome to work with. All of the guys doing the work were super polite and respectful. All easy going and willing to help however they could. I had some tile replaced in my basement in front of my fireplace and it came out looking amazing. They also did some demo to remove old paneling and put up new plasterboard and did a texture plaster job on the walls. It came out looking absolutely incredible! Also as part of the project I needed to have low dust and not a lot of mess since I have some pets and a young child. They accommodated in spades and did a really good job. 10 of 10 will hire again."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
