"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"

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"An Outstanding Renovation Experience with White Maple Construction From outdated to ultramodern, White Maple Construction led by the brilliant Ryan Brining has executed an awe-inspiring transformation of my kitchen.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."

"Matt and Donna Pickford run a upstanding company. They provide you their critical eye on what 'ought to be done' and then stand back and let you make your own decisions. They PCS are totally non-pressure company. I know this sounds trite and tired but, they made me feel fully empowered and that I was making intelligent decisions. Without a doubt, aside from the magnificent job they did on bringing back to life a dead and haunted basement, this duo, Matt and his wife Donna, turned my basement into a truly MAGNIFICENT SPACE. Heck, all I wanted was to establish a 'clean space' to store household essentials. Well, they transformed this basement area into a most DIGNIFIED AREA. In fact, when company arrives, I lead them down the staircase that THEY Re-FURBISHED to show off this extra space of my home. PCS has made me so proud of my basement. (Now, that's a statement I thought I'd never say.) Their staff, their team, the the team that executed the work - were professional and dignified."

Addition to existing structure building services FAQs

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
