We build additions and new construction - from the ground up - or renovate down to the studs. Our mission is to provide excellent workmanship and customer service. We strive for our clients satisfaction from beginning to end of the project. We pride ourselves on fast, friendly and quality service. We look forward to your business!

"I recently purchased the house that was built by Incline homes. I like it. The reason I am giving one star is the ongoing issue with my AC. It's not working properly and it's 100 degrees outside and 80+ degrees inside right now. For 3 weeks I've been calling their office, leaving voicemails, sending emails. No one ever returned my calls or responded. All I get is the technician that keeps texting me promising to stop by. Never happened. I still hope Incline homes sees this review and resolves this issue. I will gladly change the rating if it happens."

Before starting my business in 1996, I spent 12 years in the military (1st class builder in the U.S.NAVY SEABEES), doing construction all over the world. I do not use sub-contractors, and I am fully insured. Various discounts available, Including seniors, and of course veterans!!. Please mention Angie's List when you call 412.310.4643 to schedule.

"The "roof repair" cost me $4,275.00 and the leak into my bathroom was worse before he fixed the roof. He did do a great job in painting my garages but wanted t charge me extra to paint the side door and the side window because I didn't specify that it was part of the garage when I hired him. LOL. He painted 4 pieces of wood which made of a section of fence the wrong color. But then I fiqured out the wrong color of paint on the fence and the not painting the garage door was because he ran out of the brown paint. I had the roof leak fixed by a very reputable roofing company and it was 1/4 of what Furko charged to do nothing. Needless to say I won in court. Furko now has a nice judgement against him which I am sure he will never pay. Would I recommend him or hire him again H*** NO!!!! The 1st picture is how my leak looked inside my bathroom when I hired Furko and the second picture was how it looked AFTER he "fixed" the leak and I paid him $4,275.00"

"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."

"Basic Concept designed and built a deck in our back yard and did an entire kitchen remodel for our home. We had some different ideas when we first contacted Charles but he was able to see what was possible and make great suggestions to fit our wishes, space, and budget. All of the workers that came to our home were very skilled, polite, and professional. They made sure that all work was done completely and correctly, no shortcuts. Charles was very involved in every aspect of the project. He is a great communicator and coordinated all the work and deliveries very efficiently. While I'm sure the size of our kitchen and deck would seem insignificant to some, we were made to feel like VIPs. Everyone treated our home with dignity and respect. High quality products and workmanship. Our house looks great. We are very pleased. We highly recommend Basic Concept."

FAQs for addition to existing structure building service projects in Pittsburgh, PA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
