"The crew from Foundation Support Specialists, which included Hector Roman, Eddie Sanchez, Ricky Rodrigez, and Mark Willis, did a fantastic job installing piers under the stem wall between my garage and house, and also encapsulating and insulating the crawl space in my basement! They worked quickly and tirelessly to get both jobs done despite having to work in 95+ degree weather with no air conditioning. They were all very courteous and took great efforts to keep the areas they were working on clean of any debris. I will definitely use them again for any future foundation work, and highly recommend them for similar work for anyone needing these types of services."

"We started a DIY to replace a toilet. We saw the builder’s plumber did a bad job on the flange. No screws to hold it down but a lot of glue. We had 3 plumbers come in to review and give us their input/quote. John explained what he wld need to do. The quote was reasonable. Best part, he wld not need to bust up the tile or go underneath the foundation. We are very pleased with his work along with his apprentice. We will recommend and use them again. Thank you."

Basement Waterproofing FAQs, answered by experts

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
