"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

From stylish kitchen renovations to bathroom remodels to full-home projects, Chapter makes it easy to turn your vision into a reality, all while keeping your project on budget and on schedule. We?re fully licensed and insured and have a depth of experience to elevate your home.

"Don?t be fooled by Chapter?s sleek branding or ?hassle-free? pitch. Our semi-gut reno of a 3-bed, 2.5-bath Brooklyn co-op has dragged on for a year, burning money, time, and sanity. Chapter claimed high-end services, but this was not the reality. There was minimal project management, workmanship was terrible (damaged new items, blamed ?site conditions? when they couldn?t do basic work they?d promised, had to re-do many items because quality was so poor). They missed every deadline and overshot the timeline by months. We were often forced to procure items ourselves because Chapter weren?t engaged or competent enough to do so (they even failed to purchase a one-of-a-kind marble slab we designed our bathroom around. It was sold to someone else and we were forced to redesign last minute). They gaslighted us whenever we raised concerns and pressured us to make payments when work was defective / incomplete. Beware the other glowing reviews you read. "

FAQs for addition to existing structure building service projects in Gillette, NJ

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.
