"I hired Kevin to remodel our two car garage into an extra room, along with building a laundry room along with plumbing, hallway, replacing garage door with a new wall/siding, new windows etc. Kevin Babcock and his team have been an absolute pleasure to work with. They are responsive to the needs of the homeowner, readily available throughout the entire project and amazing to work with. Kevin ensures his clients are constantly kept in-the-know about the progress and openly accepts feedback and ideas. He not only was attentive and accountable but his team does impeccable work that left us with a life changing home remodeling to accommodate our growing family. I would recommend Kevin to anyone for his skill, expertise and integrity and will continue to hire him for future projects of our own."

"Basement Renovation. Work began on Feb 3. The Government imposed a work stoppage due to Covid-19 on Mar 22. Work resumed on May 15. Work completed on Jun 8. Proworks did an outstanding job renovating our basement. John and his team efficiently completed each phase providing design tips and suggestions along the way as we requested changes here and there during the build process. We would use Proworks again and highly recommend them!"

"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."

Basement Remodel questions, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.
