Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade, combined with our ability, is what makes us true professionals.

"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."

"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."

Douglas Marshall Cooper Associates is a full-service design and construction firm whose practice encompasses both new and existing buildings of residential and commercial use, as well as speculative housing and development. Mr. Cooper’s office is located in Pound Ridge, New York and includes a staff of himself, an associate partner, three assistants and a host of carpenters, masons, and laborers, in addition to various subcontractors that work on projects small to large. Douglas Marshall Cooper Associate's roots are based in Construction, Design, Real Estate Investment and Development & Construction Management. Our portfolio includes a wide range of work across these fields. Our uniqueness comes from understanding what it is to be the Owner, the Developer and the Builder –- a trifecta that is evident in DMC Associate's core portfolio of prestigious residential, commercial, and corporate projects. Douglas Marshall Cooper Associates, LLC...a solid track record. A powerful future.

"I wish I could give zero stars. We hired Douglas for a kitchen remodel which involved installing a kitchen island, pantry, and all the related plumbing and electrical work. The communication between Douglas and his carpenter was terrible. We submitted sketches and agreed upon the design for the cabinets which were meant to be overlaid. When the island arrived, the cabinets were inset which did not match the rest of the kitchen. In addition, the kitchen island has split and cracked at more than half of the joints. The pantry cabinet has split and areas of unpainted MDF are showing. We have needed to paint and touch up many of these spots. Regarding the plumbing, we have had multiple significant leaks from piping and tubing that the team installed. Water has leaked even through the floor and into the basement. Upon review from other plumbers, all have confirmed the parts used were cheap and of low quality, and the workmanship was subpar. After a major leak in the middle of the night, we reached out to Douglas and respectfully voiced our issues and complaints. He ignored us for a full month, and then instead of simply stopping by to take a look at the problems (which would have been the first major step to alleviating our frustrations), he responded in a despicable manner. He even included the following quote from his lawyer, He laughed saying that perhaps you lost your job (due to the CoronaVirus) and were probably scrounging for any money you could scrape up. Who would want to work with someone like this?"

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.
