"Blake Excavation was recommended and we are ever so grateful! Our Septic Drainfield had failed after 42 years and we were in need of urgent help. Despite delays courtesy of an understaffed DEQ Jason kept us informed and was onsite the minute the permit was approved. The crew showed up on Friday and worked through the weekend to get us back online. They were courteous and caring and we are ever so grateful!"

"Andrew and his Crew from Roseburg were wonderful. They were able to get into our crawl space and did an amazing job clearing it out, installing drainage, a layer of plastic and sump pump. They left the area so much cleaner than it was when they arrived and they explained everything to us clearly so we would know what to do. We recommend them highly and it was a pleasure to meet them."

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Basement Waterproofing FAQs, answered by experts

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.
