Homeowners Want to Know:

What should I look for in a foundation repair company?

When choosing a foundation repair company, consider factors like their experience, customer reviews, warranty offerings, and whether they provide a detailed inspection and estimate. It’s also important to verify that they have the necessary licenses and insurance to operate in your area.


How do I know if my home needs foundation repair?

Common signs that your home may need foundation repair include cracks in walls or floors, doors and windows that stick, uneven floors, and gaps around exterior doors or windows. If you notice any of these issues, it’s wise to have a professional inspection to assess the extent of the damage.


What are the benefits of professional basement waterproofing?

Professional basement waterproofing protects your home from water damage, mold growth, and structural issues. It can also improve your home’s resale value and provide peace of mind by ensuring your basement stays dry and safe, even during heavy rains.


How do foundation repair warranties work?

Foundation repair warranties vary by company, but they typically cover the workmanship and materials used in the repair. Some warranties are transferable if you sell your home, which can be a selling point. Be sure to ask about the duration and coverage of the warranty before choosing a company.


Can I get an estimate for foundation repair or waterproofing online?

Many companies offer online tools or virtual consultations to provide initial estimates for foundation repair or waterproofing. However, an in-person inspection is usually required for a detailed and accurate quote, as the repair needs can vary significantly based on the specific conditions of your home.
