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 Dumont, NJ

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
