"From the second Kevin walked in for our estimate I could tell he was genuine and not trying to oversell or take advantage. Our project was a basement remodel for my mother who was moving in. The entire experience was wonderful, from start to finish. His team is amazing, super dedicated and we were involved in every step along the way. Kevin was always right there talking my mom through what she needed, helped her pick out her finishing touches, and even suggested we add/remove things from the remodel we would have never thought of doing on our own. He never once made us feel like we were asking too much and ANYTIME I had a question or concern he always got back to me same day. His work is top notch and his team is filled with the kindest group of men I have ever met. I didnt always make it easy, but they always delivered. We could not be more thrilled with the way things turned out, down to the last details, and would 100% call Kevin and his guys back for any future contracting needs."

"f you want the short story- put your mouse away, close the computer, stop the hours of research and reading reviews. Pick up your phone and call Alexs (845) 741-8607. This is the only company you will need for all of your new or old construction needs, at very reasonable rates. Keep in mind, AMV is in demand and you should schedule ASAP if going forward. Now for the long story- sit down grab a beer or cup of coffee. Meet the amazing crew: Aleks (the Magician), Mike (the Perfectionist), Benny (the Astounding Albanian) and Jerm (the Talking Bull). After calling AMV for an estimate, Aleks scheduled a next day appointment. Aleks shows up at our agreed time and this is where the best contractor experience I have ever had begins. We go over the scope of work I would like done. There is one task Aleks tells me up front, that he has never done before, and that is the knockdown texture on the ceiling. Rather than bringing in another contractor just for the ceiling, we agree to give it a try with the understanding if I do not like it, I will not be charged. Aleks points out the many mistakes I had in my design thoughts. We go over his suggestions, which I might add, were all beneficial up the line. There was no up selling, just great ideas. Two days later I receive an email with proposal, we make some changes, and agree on the price and start date. The magic transition begins on the start date agreed on. The van pulls into my driveway at 8:15 AM, just like it did every day going forward. Starting each morning with a handshake and hello, the day begins. For the most part, you can expect a full day of work each day. The exception would be if the crew has completed one task and there is no sense in starting a new task with time constraints. You will always see either Aleks or Mike with Benny or Jerm, or all 4 on any given day. The biggest take away here is that these guys do not cut corners and will do ANYTHING to make the job right, and you happy. Another worthy note to keep in mind is, along with quality work, AMV uses only top quality materials, right down to the screws and nails. I remember at one point, my wife and I were not sure of our choice of backsplash color that we had picked out. Aleks already had six square feet up on the wall. We told him we were not feeling our choice of color. His response was, “No problem, I can take it down now. I will start over with your new tile, don’t settle, you will be looking at it for a long time. You have to love it now.” If that wasn’t enough, the new tile we picked out that night at Lowes needed to be special ordered, with a two week delay. I called Aleks from Lowes, knowing he had his next job scheduled during that time period. His response was, “Get what you like and we can work it out.” I realize time is money and I caused him extra time. The only thing in his thought process was to make me happy. By the way, Aleks did his homework on the knockdown texture. He was relentless until he got it right. It looks great! I would like to touch on my comment, “plenty of extras.” Here are just two examples. The crew was constantly going up and down my basement stairs for supplies. While doing so, Aleks noticed that my stairs were shifting from the wall. He made me aware of the danger of collapsing. At some point, I go to use the stairs myself and bingo, the stairs are sturdy like new. The other example is, I had a charging cord for my cordless vac, going from my dining room outlet and wrapping around the wall and basement door jam, to the vac on the wall of the stairs. Next thing I know, I have an outlet on the wall of the stairs for direct connection to my vac. Tell me, what contractor does this without gouging you? I am convinced, you will not come across a more honest and helpful group of guys in the construction business. From what I’ve seen, they can do it all. You need to call AMV for your next job! The only thing left to say is that our dining room/kitchen looks more amazing than we ever dreamed of and the deck will last a hundred years. Thank you Guys, for an amazing job well done."

"I have no skills or vision when it comes to construction, so there was no way I was going to attempt any part or function to finish my basement myself. There is so much involved with finishing a basement that the actual thought of getting it done was exhausting! John and his team made the large task to finish a basement easy! John has the skillsets to do the work and orchestrate different contractors with various skillsets to get each phase of the construction done. Proworks Interiors is very professional and know what they are doing. It was a great relief that they were able to make something that seemed impossible, possible in a matter of a few months."

FAQs for basement remodeling projects in Cornwall, NY

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
