"I used Perfect Done construction a year ago and Iâ m writing this review since it was kindly requested. I found Perfect Done Construction online had them complete a house remodel and roof replacement for my home, and I am extremely impressed with their work. My biggest concern was finishing the project on time but Sal and his team ensured me and finished just on time. The finished renovation is beautiful, and I couldn't be happier with the results. I only recommend the best choices and I am very confident in recommending Perfect Done Construction for any construction needs."

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. "

Our mission starts with how we propose your custom new home building construction project. We want and prefer you see the phase-by-phase costs we incur from permit to clean up. When you receive our proposal, you will notice that we proposed a cost plus a fee pricing, usually referred to as just “cost plus,” or “open book”. This is defined by adding two components together: Costs the builder incurs to deliver the scope of work + Builder’s fee for delivering the scope of work at builder’s cost. Open book provides the transparency missing from a lump sum price. It allows you as the client, to share in the benefits that come from 0% markup on material and subcontractors. Every two weeks you receive and budget vs actual spreadsheet allowing you to apply savings to other scopes that may have been cost prohibitive. We as builders pass project savings to you, our fee is transparent. See the video for more...https://www.youtube.com/watch?v=XnuIc3GrBWA

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