"We needed some work done in our basement and needed the work done quickly. Called Harvey and the work was done in 3 days and at a fair price. They remodeled our home in the poconos in less than one month and we get so many compliments from our renters. We will definitely use their services again. Thanks Harvey!"

"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"We had Tom and his crew remodel our small master bathroom a couple of years ago and invited him back to do our kitchen remodel. Tom and his crew are incredible. They are very professional, considerate, and clean. They do the job right and don't cut corners. His pricing is fair and I would be happy to use them again on my next project."

"I couldn't be happier with both Nayol and his fathers renovation to my home. That also includes their employees. Their prices were amazing, very attentive to any questions I had and completed the work quicker than I expected. They will be completing all of my homes repairs and upgrades. In fact, I am currently in contact with Nayol for an estimate for some future work."

Basement Remodel FAQs, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

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.
