"American Home replaced my roof and siding, porch windows and some add-on exterior lighting. One of the reasons I chose AHR was not just due to the best price, they came in line with other estimates I received, but because they included things with their final price that similar companies had as add-ons at an extra cost such as the dumpster and gutter system. I did not know what to expect as this was the first time I've had these things replaced. My rep John was awesome, he was professional, friendly and accommodating, and was able to work with me on the spot vs. "I have to check back to the owners" which I got from other companies. John was readily available by phone, text, and in person. He walked me through all the steps, timelines, and the whole process. After the crew finished, he took my list of 'nit-pick' things and made sure they were addressed. Overall I am satisfied with the job, In fact, we recommended them to our neighbors who hired them to do their siding this Spring."

"Inson is a creative genius with a superb eye. He did everything with meticulous detail and completely transformed our apartment into an amazing, gorgeous home. We enjoy entertaining, and our friends love coming over, always remarking how beautiful and inviting our home is- and that was exactly what we wanted, except Inson brilliantly upgraded our concept, within budget and on time (even with our aggressive timeline because we needed to be out of our old place and into our new within months!). Inson’s team was also great to work with - always polite and professional. We highly recommend Inson and plan on working with him again on our Hamptons home!"

With over 25 years experience, family owned and operated. We are a home improvement contractor that pride ourselves on being available for our customers, standing behind our product, service and labor. Focusing on kitchen and bathroom remodeling in the New York City and Brooklyn area working on brownstone homes and apartment renovations.

"Mark took a deposit from me and then never followed up on submitting the proposal I signed to my co-op and getting approval. Finally almost a year later, I asked for the deposit back, and he said he would mail immediately after briefly trying to convince me to still let him do the job, because it was simply "out of sight out of mind". That was 2 years ago. I'm filing a small claims case against him/the company tomorrow."

"In 2024I hired pro. Solutions to build a back deck with an extension. I asked them to rebuild my front porch, and I put a fence around my yard. They are a scam artist. They outsourced my work to another company. They barely came to work. They told me I had to wait a year later to stained and sealed. The wood April of 2025I started calling them. I got a hole to Guy he said that he would have someone come out and start the work. No one came here until August of 2025. They sent one guy, 15 gallon bucket of something that wasn't even the color nor was it stain and seal the guy Joey, it took a month. He was here 3 days within that month. And then get half of the fence done, Dennis never answered my calls. I called him over and over again to where they even knew my telephone number and they wouldn't answer the phone so I called for my husband's phone, and then they stopped answering his phone calls. This company is a piece of s***. Do not do not hire them"

FAQs for addition to existing structure building service projects in Spring Valley, NY

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.
