"I interviewed a few people before making my decision using Rok and Iâ m glad I did. I did a complete gut renovation and he basically made my revision come to fruition. Even with the delayed/problems with renovations he always kept me informed. U told me he would always have someone at my house working and that he did. Not like the contractors Iâ ve worked with in the past that say that but then once they get the job.. the â oh someone would be thereâ and no one comes. I had a leak issue and he made it to my house 10 pm to assure it was taken of. Roc is reliable and hard working."

"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local. The last part is important because he understands the importance of reputation which gives me full confidence in his work. I will definitely be coming back to him again for any future work on my house and wholeheartedly recommend!"

"I wholeheartedly recommend P Bright Construction Corp. We?ve used them to address flood damage, repair and replace the front door our coop and update closets in our own unit. Their flexibility was remarkable. That?s probably what I appreciate most. No build plan is perfect, there will always be a few unforeseen problems. Ezequiel and his crew handled all the unforeseen issues gracefully and recommended great suggestions to deal with these problems. This adaptability demonstrated their commitment to ensuring the final result met my needs, even as those needs evolved. They paid great attention to detail. They understood what you cared about and this shows up in the recommendations they make and the quality of their work. Their estimates are very fair and they completed their work on time and on budget. I highly recommend P Bright Construction Corp. Their flexibility, attention to detail, punctuality & reasonable pricing make them an excellent choice for your next reno project."

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