Best basement waterproofing pros near Fort Harrison, MT

Q: When should you not use a dehumidifier?

• <div><p>Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze. </p></div>

Q: Does a basement need ventilation to reduce humidity?

• <div><p>Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.</p></div>

Q: How much does it cost to finish a crawl space?

• <div><p>If you don&rsquo;t wish to dig it out and convert it into a finished basement, you can still <a href="https://www.angi.com/articles/how-much-does-crawl-space-encapsulation-cost.htm">encapsulate your crawl space</a> to protect it from damage for an average cost of <b>$5,500</b>. Finishing a crawl space beyond this isn&rsquo;t really worthwhile, as the low ceilings mean you won&rsquo;t be able to use the area as living space.</p></div>

Q: What is the best type of insulation for crawl spaces?

• <div><p>Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.</p></div>

Q: What type of foundation repair is best?

• <div><p>The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don&rsquo;t address the source of the issue. Some examples of more temporary solutions include <a href="https://www.angi.com/articles/how-much-does-mudjacking-cost.htm">mudjacking</a> or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.</p></div>

"we had concrete pads added after home construction. One pad had a 2 inch settlement on one corner. Complicating this was a stone wall sitting atop the pad. Excellent restoration was done by Groundworks From Bozeman. After a thorough evaluation by Ben, Chelsea and Tyler were prompt, educational and successful. I Highly recommend this company for your concrete/foundation needs."
