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."

We are a family owned and operated business since 1988. You will receive personal one on one attention directly with the owner. We are a design build company that can take you through every step of your project with the utmost professionalism and detail. We always encourage communication as we schedule weekly meetings throughout your project. We do this so the project stays on track and all details are given our full attention.

"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."

"I had a great experience working with Tim to add a large sports room onto the back of my house in Etna. I had several conversations with him about what I was looking to do and then he put together a very reasonable project. I really like how Tim manages the money and the various contractors he works with. He put together a plan for me paying him based on the various milestones of the project, which then involved different people for the foundation, insulation, drywall, electrical and so on. This kept everyone on schedule and the entire addition was completed between April to early-July of 2023. I also had him put in hardwood floors throughout the entire first floor of my house. It is such a great improvement to the living space. Just excellent work and completeprofessionalism from Tim and his crew and the contractors he works with. True to form, Tim has stopped by since then to check-in on things and answer any questions I've had. I will definitely work with Tim again."

When reading the reviews that my customers wrote about work that I have completed it will provide you with definite reassurance that no tasks can not be done.

"They were great! Squeezed us into their schedule and the work was done beautifully. We needed interior doors planed down so they would shut correctly, as well as a bathroom exhaust installed with electrical connections added. We are very pleased and will be hiring again if needed! "

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.
