I can provide some general information that may help you understand the situation better.
Water damage restoration companies are often called in to assess and address water-related issues in homes or buildings. When there is a water leak, it's essential to take prompt action to prevent further damage and potential health hazards like mold growth.
The decision to replace tiles and drywall will depend on the severity and extent of the water damage. If the moisture has seeped into the tiles and drywall, it could compromise their structural integrity and lead to mold growth, which can cause health problems.
To determine the extent of the damage, restoration companies use specialized tools like moisture meters to measure the level of moisture in affected areas. If the moisture levels are high and there's a risk of structural damage or mold growth, they may recommend replacing the affected tiles and drywall.
However, it's always a good idea to get a second opinion and quotes from different restoration companies before proceeding with any major repairs or replacements. Sometimes, less severe water damage can be mitigated through proper drying and restoration techniques without needing full replacements.
If you're uncertain about the legitimacy of the company's assessment or recommendations, you can consult with an independent contractor or a water damage expert for a thorough evaluation.
Additionally, you should review your lease agreement and check whether water damage is covered by the landlord or tenant in your specific case. If necessary, contact your insurance company to understand your coverage and potential reimbursement for restoration costs.
In any case, it's crucial to address water damage promptly to prevent further issues and maintain a safe living environment for your tenants.
