"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

"The entire project took 9 days and involved a crew that was exceptional in every way. From Terrie to Tom, Rich (the owner), Alberto (the project manager), Eusebio (Alberto's right-hand man), and the entire team--they were the most respectful, diligent, patient, and fexible crew I've ever worked with.

"They recommended a good solution for the occasional shallow flooding in the garage (installing a sump pump) They started soon after we submitted the request and they did a good job. Most importantly, the pump kept the garage dry through our seemingly endless rains this winter. There are 2 reasons I rate the job with 4 stars rather than 5. (1) The job did not pass the city’s inspection and a critical connection had to be reconfigured (after which it passed) and (2) there was some weirdness around payment on the last day of the actual work (before the inspection) in which the crew seemed unwilling to leave without a check and then were slowly driving around the neighborhood afterwards. When I brought this up with my contact at the company, he denied that the van was theirs (which it definitely was) and didn’t really explain or defuse the bad feeling this created. But … they did a good job and in this day and age that’s really important and can’t be taken for granted. I recommend this company with the suggestion that paperwork, permitting, terms of payment etc should be clearly settled in advance."

Basement Waterproofing questions, answered by experts

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

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. 

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.
