Miller Contracting, Inc., offers design services for all of your projects or we can work with your architect. We look forward to working with you, so please give us a call today!

"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."

Home remodeling company that has myself and my help working hands on, on your projects. (not some g.c. You only see when you sign checks.) I use sub contractors to do my plumbing and electrical work. I am licenced in pa.as a contractor. My # is 055911. Each job is priced seperately. Bigger projects by contract. I can work on smaller jobs by an hourly rate usually $45.00. I carry $2,000,000 liability insurance. (that i have never used). I have never been sued or brought to court. I have alot of repeat customers which speaks for itself. I think of myself as a honest man who just wants to provide a good quality service to people who need someone they can trust with their biggest investment. Their home! I have lived in ireland england and the u.s.a. And have worked in the construction indusrty in all three countries. I have a degree in drafting helpful in instalations and design changes. I belive that the customer is always right!!! I do all and any work that comes my way. Not too proud to do small jobs. You never know where it will leadto. I fixed a leaking skylight for $150.00 and the next spring built the same customer huge wrap around deck for $20,000.00. Call 412-414-5870.

"My wife and I wanted to remove a load bearing wall in our house, and hired Bob and his crew for the job. They were absolutely exceptional from start to finish. Bob did brilliant work moving ducts and with his finishing work to make the house look as though the wall had never been there. I not only would, but I would ONLY hire Bob and his guys for any contracting work we need done in the future. I can not express how highly I recommend them."

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