"Eastern Maine Drainage was quick to assess our problem and Nate was able to set up an appointment within a few days to remedy our drainage issue. He was on time, communicated clearly, and was tidy with his work. Since I was at work while he was installing the new sump pump and drain line, he kept me in the loop about his progress. He had a detailed estimate that he stuck to, and he even deducted the cost of some PVC when he realized he didn't need as much as he initially planned. I would recommend him to anyone needing work in their basement."

"I called Octagon the day after we had an upstairs water leak. The next day, Octagan had scheduled a technician to assess the damage and set up the mitigation solutions to dry out the damage before mold could set in. Everyone from Octagon was friendly, professional and very responsive. If you need a fast, reliable and effective response, you will find it with Octagon!"

"This project was supposed to be "phase one" of three projects that we hired NE Renovation to complete.  On day one, the basement was prepped - all carpeting was covered and baseboard heating covers were removed.  Sheetrock was supposed to be installed on the next day, but due to a serious injury to the sub-contractor, that was not done.  Instead, demolition work began on what was supposed to be "phase two" of the project - the remodeling of a bathroom.  We had not been expecting this change in schedule and to be fair, neither did anyone else.  The basement project was put on hold until an alternate plan could be made.  A few weeks later, work began again on the basement.  The sheetrock was installed very well and in quick time.  The plaster work was completed perfectly which was no small task given the length of the walls. Additionally, the paint job was done perfectly.  The new six-panel doors, wall mounted television, upgraded lighting, and new baseboard heating covers helped complete the transition of the space from 1970 to 2012!

The value we received from this project has exceeded our expectations.  We added a pool table and two sectional sofas to complete our new recreational space.  It serves as a great "man cave" as well as a great place for family and friends to hang out.  NE Renovations did a great job renovating our basement."

Basement Waterproofing FAQs, answered by experts

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

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
