Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"I have hired many contractors from Home Advisor but this my first review. This team is amazing. They show up on time, clean up after themselves at the end of every day, their work is amazing and they have great attention to detail. I had Owens Corning wall panels in my finished basement, they were here when I bought my house and I hated them from day one; they were too industrial looking for my taste. Anthony and Michael removed all of the double layered panels in a 1500 sq ft basement and disposed of them. They put up drywall, did all of the finishing work, put all 20 receptacles back in, put up floor and door trim and painted. They also replaced two casement windows and rehung two doors that were not installed properly by the previous homeowners. I plan on hiring them to replace the antiquated drop ceiling next."

These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Basement Leak Repair questions, answered by experts

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

In most cases, standard homeowners insurance policies cover water damage from sudden, accidental damage, like burst pipes and leaking appliances. However, water damage caused by flooding, groundwater seepage, or heavy rain is likely to be excluded from coverage. Check your policy to be sure, as some plans include opt-in flood insurance coverage. Certain companies also allow homeowners to add an optional water backup endorsement to a policy.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.
