"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.

"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

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.

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.

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

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.
