"Ryan, Sr. Inspector, was professional, courteous, and walked me through my basement, pointing out what needed fixing and exactly what would be done. Came on time and left on time... cleaned up their mess, too! Very fair pricing, definitely worth every penny for a mold-and-moisture free basement! Very highly recommended!"

"We are extremely pleased with the job Enviropro did in our basement. The price was reasonable (relative to others we contacted), and the sales call was friendly without the high-pressure nonsense of some other waterproofers. One key to my decision to hire them is that the Lifetime Warranty is backed not just by EnviroPro, but also by the national company that created the system they use. The work was done according to schedule, with far less dust and mess than we expected. The crew were very communicative and they cleaned up after themselves. It's like having a brand new basement. We couldn't be happier, and do not hesitate to recommend Mike and his staff."

"I hired Alliance to complete several jobs in my newly purchased home including: 1. bringing bathroom and kitchen plumbing up to code, 2. installing a garbage disposal and faucet, 3. installing a new toilet and fixing plumbing to toilet, and 4. multiple pinpoint leaks and pipe corrosion in the basement plumbing. From the start, it was such an easy and stress-free process. Communication was constant through email and text about the service dates and ETA of the team members, which was fantastic as I was traveling back and forth between my current and new home. The estimator (Mike) was at my home the day after I made the initial call and walked through everything with me in a friendly, well-informed, and pressure-less manner. He never tried to upsell me and, in fact, helped me prioritize the most important items to address. The plumbing technician (Andrew) was at my house five days later with all of the required materials and worked for 8 hours on the various items. He even found and fixed another broken component while working which probably saved me additional stress and money! At the end of the service, he walked through all of the fixes, went over the warranties associated with them, and ensured my satisfaction before processing payment. He was so impressive that another contractor working on the painting in my home asked him for Alliance's business card. I would hire Alliance again for any plumbing need and would recommend them without hesitation to friends, family, strangers, or anyone else with plumbing needs!"

Basement Waterproofing FAQs, answered by experts

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.

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.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

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.
