"Very professional, friendly, and prompt service.  They took time to explain what had caused the damages to the roof and what needed to be done to prevent the damages from re-occurring.  Also, they explained the benefits of a full roof replacement vs just repairing the damaged area.

Basement Waterproofing FAQs, answered by experts

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.

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.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.
