"Once started the work was done quickly. The original scope of work for concrete finish was changed at my request to use exposed aggregate making the pad look like one single pour. Wow, looks great, money well spent. Gable roof with cathedral ceiling and finishes match perfectly. Looks like it has always been part of the house. Light landscaping was also provided to repair lawn from construction damage. This was done by the contractor without charge or my request. There was a small leak that the contractor repaired after several trips. This was resolved to my satisfaction. The point here is the contractor took responsibility and returned until this was resolved. We love our new patio, it’s perfect!"

"I am so thankful that I found Brodys Services! My toilet wasnt flushing good & little moths were appearing from the drain. I had 2 plumbing companies come and each one had a different opinion and quoted high prices. My third estimate was by Brody. He was a good listener & very polite. He tested my plumbing and found the problem was a cracked pipe under the toilet. He had to jackhammer the floor, fix the pipe and re-cement the floor. He put plastic on the door ad kept the dust contained and cleaned everything when he was done. I was so pleased with his work and affordable prices, I decided to do a remodel of the bathroom. He removed my tub and installed a large shower, new vanity, toilet, and floor. It looks wonderful! He worked according to my schedule, gave me his expert opinion, and cleaned up daily. I am so happy with the results & his price. I would definitely be using his services again!"

"I donâ  t know where to begin to say how satisfied I am with A & J Contracting! I needed my basement renovated ASAP and Mr. Anthony met with me in a timely manner explaining in great detail the work he would perform and how pleased I would be! Let me tell you he did NOT disappoint because he and his partner Mark performed what I call a â  miracleâ  in renovating my basement and went above and beyond my expectations!!!! Iâ  ve shown many the before and after pictures of what I now can call my family room and the response each time was how â  beautifulâ  of a job Anthony did!! If you are in need a great contractor donâ  t look anywhere else but A & J Contractor and call Anthony NOW! My family still canâ  t believe what A & J Contractor did with that old and in bad shape basement!! Very professional and the many years of experience really was on display!! Thank you again Anthony and Mark for restoring our basement!! Iâ  ll definitely be utilizing them in the future and wonâ  t have to look elsewhere!!"

"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."

"Diamond Construction did a great job with very extensive repairs to my home that was severely damaged in a gas explosion across the street from me on Aug 12, 2023. These repairs involved many different parts of my home and took almost 6 months to complete. Doug and Rich Hubner were very helpful throughout this lengthy process and helped my wife and I navigate the many unknowns and confusing details of the rebuild. Both Doug and Rich were always available and answered our many questions throughout. I would enthusiastically recommend using Diamond Construction for any home rebuild, remodel or home additions you may be considering."

"Working with Wallstructures went well. John was responsive, professional and did good work. We were working in a tight space with significant infrastructure (electric/water lines) that needed to be considered and I think that John would have rather not had those concerns to worry about, but when issues came up he worked with us to come up with acceptable solutions. I would hire him again to build me another wall."

"We went to Omnipro for our patio and retaining wall. Greg was super helpful and very easy to talk to! It was nice seeing all the different blocks and pavers before making our purchase. I highly recommend you stop in and get your project started! My backyard looks amazing now!"

"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!!!"

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