"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 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.

"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

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs.
