"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."

"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."

"Jesse did a great job installing the under cabinet lighting I got my wife as a present. He installed the new LED under kitchen cabinet lights which included installtion of the low voltage transformer/converter and light switch/dimmer. His experience was evident with his selection of dimmer switch location and optimum running of wiring to cover both sides of the kitchen cabinets."

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. 

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

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.
