"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."

"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"

White Maple Construction is a General Contractor in Oakland, NJ specializing in residential renovations and additions and custom carpentry. We are a full service contractor that will be your one point of contact throughout the project. We focus on reliability and efficiency and work closely with the homeowner to make sure your vision is realized and your expectations for the project are exceeded. We work with experienced professionals and oversee every aspect of the project to make sure the scope of work is executed as promised. We provide comprehensive project services from architecture to completed construction.

"An Outstanding Renovation Experience with White Maple Construction From outdated to ultramodern, White Maple Construction led by the brilliant Ryan Brining has executed an awe-inspiring transformation of my kitchen. They catapulted my cooking space from a â That 70s Showâ backdrop into a sleek and sexy entertaining space reminiscent of the opulence seen in â Successionâ . The transformation started with the meticulous removal of the decades-old vinyl flooring, layers upon layers of it, an endeavor that revealed the teamâ s dedication to detail and quality. What followed was a thoughtful renovation plan that involved knocking down unnecessary walls, instantly opening up the space, and infusing it with modern chic design elements that I could only dream of before. A particular highlight of working with White Maple Construction was the teamâ s exceptional responsiveness. Ryan and his team promptly answered every call, making us feel heard and valued at every step of the project. They even went above and beyond, coming over late in the evening to address a concern about our heating system after a dayâ s work, demonstrating their genuine care for our comfort and satisfaction. Beyond their aesthetic expertise, what set White Maple Construction apart was their seamless collaboration with skilled plumbers and electricians. Their collective attention to detail and mastery of their respective crafts was evident in the precision and quality of their work, instilling confidence in us throughout the process. Despite their luxurious execution, White Maple Construction operated with budget-conscious efficiency. They made it possible for us to achieve our dream kitchen without breaking the bank. They turned a dated, enclosed space into an open, modern, and functional masterpiece, making us feel rich in style without feeling poor in pocket. Iâ ve included some before and after photos to give a hint of the transformational magic conjured by Briningâ s team. However, no picture can fully encapsulate the astounding depth of change made possible by these skilled professionals. To sum it up, if youâ re looking for a construction team that delivers on promises, exceeds expectations, and takes your design dreams to the next level, White Maple Construction should be your go-to choice. Their fusion of outstanding workmanship, efficient collaboration, budget-conscious planning, and exceptional customer service results in a renovation experience that is nothing short of remarkable."

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
