"We used Anton and his team for remodeling our basement and garage after we had water damage. They put up replacement pieces of sheetrock which looked amazing. Absolutely no lines just perfectly level walls. Their workmanship was outstanding. The owner was on site a lot of the time and his team worked very neatly. The painting was simply outstanding. The room looks like brand new. Pricing was extremely fair especially for such quality, high end work. Anton and European Craftsman will be our only call the next time we need work done. Thank you Anton!"

Westbrook Contracting LLC offers the highest level of professionalism and quality renovations Westchester County. We strive to meet our residential and commercial clients’ individual needs and do not cut corners. Dave, the owner, is on the jobsite from the first consultation through the close of the project to ensure his high standards. Thank you for considering Westbrook Contracting LLC and we look forward to impressing you!

"I first hired Westbrook to remodel a bathroom for me in summer of 2019. It was a gut reno, the room was back to the studs. Dave's team was incredible, the work is absolutely beautiful. The team was easy to work with and cleaned up the site at the end of the day much better than previous contractors I worked with. Dave had great suggestions for how to make what I wanted to do work. When there were a few difficulties with the pieces I ordered, Dave worked with the bathroom supply company to resolve them. This year in October, we had a water leak in our front hall. I texted Dave in a panic at 6:30 in the morning and he walks me through what to do and had the plumber he works with in my house by 9am. (Don't text your contractor at 6:30, it's not nice, but Dave is an absolute hero). The remediation crew (NOT Westbrook) my insurance company sent to deal with removal of the water damaged material was not good. They knocked things down without asking questions. They damaged my marble floor and they destroyed a plaster arch that was original to my 1920s house. It's one thing to bring a contractor in to make an ugly part of your house pretty, but it's heartbreaking to bring in a crew to try to restore your destroyed home. Dave somehow managed to put everything to rights. There was fine carpentry work (a built in bench/radiator cover/storage piece that had been destroyed), plaster work (restoring the arch, fixing cracks in the plaster caused by water damage), and for the few things he didn't do, he knew someone (like a marble refinisher to restore the floors the remediation crew damaged). I also want to say that it's incredibly hard having someone work in your home during the pandemic but Gustavo was excellent. He followed COVID safety protocols completely. My hall looks even better than it did before the damage (and it had been newly done when the damage occurred). I honestly can't thank Westbrook enough for making this incredibly difficult process as painless as possible. I would absolutely use them again and recommend them unreservedly."

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