P Bright Construction Corp is committed to excellence every aspect of our business. We uphold a standard of integrity bound by fairness, honesty and personal responsibility. 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. Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"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."

NYC renovations are complex, expensive, and full of hidden costs. As an Owner’s Representative, I work for you—not the contractors—to protect your budget, prevent delays, and ensure quality work. You get all the benefits of running your own project and saving thousands—without the stress, wasted time, or costly surprises. How I Help: Project Setup – I handle building approvals, permits, and competitive bidding, sourcing multiple contractor and material quotes to ensure you’re getting fair pricing and avoiding unnecessary costs. You stay in control while I handle the headaches. Project Oversight – I act as your eyes and ears on-site, holding contractors accountable, ensuring work is done right the first time, and catching issues before they turn into expensive problems. Whether you want to be hands-on or completely hands-off, I customize my services to fit your needs. Save thousands, eliminate stress, and make sure your renovation is done right. Let’s talk about your project today!

"Every step of the process was handled with care, ensuring a smooth and stress-free renovation. They provided great design insights, helped with material selection, and maintained clear communication throughout. The attention to detail in the tiling, fixtures, and overall finish truly transformed the space into something both functional and stylish. Thanks to their skill and dedication, my bathroom now feels modern, elegant, and thoughtfully designed. If you're looking for a reliable and talented renovation team, I highly recommend Project Rep!"

"Hiring Tom and Roger is one of the best decisions I've ever made! I was introduced to Tom and Roger when I discovered a mice problem in my apartment that my building (the handymen, super, and others) tried but was unable to fix. (Tom and Roger were recommended by an architect friend who hired them for his own apartment.) Tom and Roger came in with gusto: they heard my concerns, understood the problem, took it to heart, and treated it like it was their own. They got to work exploring my apartment, leaving no surface or crevice unexplored. They found holes that the building had missed. They sealed everything, even the tiniest holes. They never once played down the problem or disregarded it as something unimportant - rather, they approached it with complete seriousness and even spoke with an exterminator to make sure that they were caring for it to the utmost degree (they even made suggestions like putting all of my dried goods in the fridge as to not leave a single stone unturned that could continue to attract mice). Ultimately, they solved the problem (when no one else had!)....and it was clear that they wouldn't stop in my apartment until the entire problem was addressed and done. I really appreciated that they came in with such a thorough and holistic approach. I loved working with them so much that I hired Tom and Roger to work on a bunch of other tasks in my home (sealing floorboards, caulking the tub, fixing grout in the kitchen and bathroom, fixing up a home office, staining the deck, insulating around the radiator, and so so much more - I had a long list!). The items were each different and they knew how to do them all. There is nothing that these guys can't do! Everything that Tom and Roger worked on was done with great care and attention to detail. They firmly believe that any work should be done by these principles - it's part of what makes them stand apart from the rest. To boot, they are lovely people! It was truly joyful working and having conversations with/getting to know them while we were in the apartment together. Working with Tom and Roger was one of the best customer service experiences I have ever had. Every day, they showed up early (early!) for the job. Throughout the day, they checked in to ensure that my list of priorities was being met (even at the end of the day, they didn't leave without checking that they had tended to my priorities.) I appreciated how they continually made the effort to ensure that we were exactly on the same page. I never felt rushed. I always felt heard. Truly, working with both Tom and Roger was nothing but wonderful. My only regret is that I don't have more jobs to give them - the experience was so great that I wish I could keep working with them! It goes without saying that I will work with Tom and Roger again in a heartbeat (in fact, they're the only contractors I ever want to work with moving forward!) and recommend them without hesitation to my closest friends (in fact, I already have!). Hire Tom and Roger - your experience will be the best and your home will look gorgeous. You will be so SO happy that you went with them!"

FAQs for addition to existing structure building service projects in New-York, 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.
