"Every step of the way was above expectations. Scheduling was easy, I was notified of ETA, and Al, our technician, was prompt and thorough. We needed our gas fireplace cleaned, and the job was done thoroughly, carefully, and efficiently. Our 25+ year old fireplace now functions perfectly and looks amazing. Can’t beat the price. 10/10 recommend."

Customers say: Quality work

"Shawn was very knowledgeable and very professional. The bathroom remodel was the master bathroom that was small so only one person could work on it but it was done within a week. He was able to keep everything neat and contained and the finished product looks great! The cost was also very reasonable and at the low end of what we had expected to pay."

"Artie was exceptionally professional and knowledgeable in a vast array of services. Artie worked for me for over 7 years preforming tasks that varied from converting a small shed to a luxury air bnb, remodeling apartment buildings, restructuring and replacing a large porch, installing washer and dryers as well as dishwashers, and various small home projects. Artie was always punctual and reliable. He completed all jobs in a timely and effective manner. He also fixed projects that were done improperly by other contractors. I also found him to be cost effective in every way. Saving myself time, money, and energy upon every job that I hired him for. Artie still works for me to this day. Heâ s my go to for just about anything and everything!"

"OC Construction did an outstanding job remodeling my kitchen! The new tile backsplash completely transformed the space and looks absolutely beautiful. Their craftsmanship and attention to detail were excellent, and everything was installed perfectly. The crew was professional, punctual, and respectful of my home throughout the entire project. They finished the work on time, communicated well, and exceeded my expectations. I couldn't be happier with the results and would highly recommend OC Construction for any kitchen remodeling project!"

"As someone building a second home in Vt., everything needed to be done from a 235 mile distance. This can feel a little scary. My experience w/ Joe was Outstanding!!! Joe approaches all his tasks whether it be contract work or time & material work w/ the same set of ethics. Get it done in a timely fashion, be fair, communicate clearly, take regular pics, send via text for approval or comment, & offer advice through his experience as a seasoned builder. If you are lucky enough to work w/ Joe, enjoy the experience, your in good hands. Bill Giglio from Ct."

Basement Remodel FAQs, answered by experts

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.
