"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"Mixed review I had spoken with other radon remediation companies and received quotes before meeting with Erickson Foundation Solutions. The salesman, Chris, seemed much more thorough in his approach and he gave a presentation explaining radon, its danger and the process to remove it. The quote was slightly higher than another quote, but I felt more confident. And with the added fan moisture guard, the system came with a 10-year warranty. So I agreed to the proposed plan and paid a deposit. Later I decided to not install concrete in the adjacent (but not connected) basement/crawl space. I asked Erickson to quote installation of plastic sheeting to seal that space. John, the sales manager’s quote doubled the total price. I already had found durable plastic sheeting for about $300. So how would that become $2000 extra? John explained that there would be a drainage mat under the plastic and it would be attached every few inches to the walls and then sealed with caulking. But besides sealing the area, the quote also included another extraction hole and piping to connect it to the fan. This seemed to me like over-kill for a 1200 square-foot house. But he said without the second extraction location, they would not warranty the job. So I accepted the “up-sell” and signed. Today the office called to tell me when the crew would arrive and they arrived on time and were very pleasant. However, they did not have the drainage mat. They called their supervisor and was told that it was not included in the quote and would be an additional charge. In fact it had been a verbal inclusion, not written. The crew was surprised that a second extraction hole was quoted, since the radon levels were not very high to start (3.8 and 5.4). So I feel that I accepted a possibly unnecessarily elaborate system, more elaborate than I probably really need, for twice the price. And didn’t receive the drainage mat that I was told would be part of it."

Basement Waterproofing questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
