"My experience was excellent, from initial call to completion of the work. Great team that showed up on time, conducted themselves well, and were committed to their work. Austin F. Conducted a thorough inspection and proposed a multistage plan to repair my crawlspace. I was especially happy that an engineering firm prepared final inspection and drawings for the county permit process. John, Austin, Taylor, and Chris worked very hard for three days, even in the rain and cold. Great company and people."

"Great! They quoted me a price, came to look at the house and gave a description of the work that would be completed. They came the next day and finished the job within two days. They were very professional, knowledgeable, and efficient. I would certainly hire Jim and his crew again."

"**Caveat emptor**. If you choose to do business with Mr. Clark, be certain to get absolutely everything he says IN WRITING! And make sure you are crystal clear about what you are getting for what you are paying. He charges a king's ransom for his work and will not acknowledge HIS MISTAKES!"

"We discovered mold around our vents inside of the house and called to have an inspection of our system. Eddie Geyer came to our home and was very professional (and polite) from the beginning to the end. We had several companies come out but chose this company due to their fair price, through inspection and professionalism. Mr. Geyer and his crew did an excellent job cleaning our vents (they had never been cleaned before). He answered all our questions and we feel confident that the vents are in much better condition now. I highly recommend this company."

Basement Waterproofing questions, answered by experts

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.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.
