"Jerry remodeled my basement last year before I sold my house. Also painted living room and dining room and replaced light fixture. He and his partner were courteous, hard-working and neat. They did a great job. My house sold in 3 days-I think partly because of the good work Jerry did."

"HVAC was not draining properly and had to reroute drain tube to sump pump well with improved gravity feed for proper drainige (needed to go behind paneling in basement walls). They did an excellent job, works like a charm!"

"We hired David to remodel our basement late last year. There was a late start initially, however the crew picked it up and did an amazing job with our basement. David clearly understood our key requirements and built the plan to accommodate the asks. He was flexible and most importantly available at all hours when we were out for selections. He recommended best options for floor tiles, cabinets and all accessories. We are extremely happy with the output and the great work Davidâ s crew did with our basement. We strongly recommend them."

"We had more than 80% of the old house remodeled with new additions. It’s a daunting task and huge project. However, Dimitritis and Joshua made it easy and did a great job in completing our dream home. Joshua was fantastic managing the daily tasks and excellent with details. They were very responsive in re-addressing even with minor adjustments. Definitely recommend."

Basement Remodel FAQs, answered by experts

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.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

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. 

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
