If you have moved to China from abroad and find mold in your home, it can be frustrating when your landlord or serviced apartment management does not take it seriously. In many cases, the common solution is simply to repaint or cover the moldy area. But this does not solve the root cause, and the mold often comes back again.
如果您是从海外来到中国生活，并发现住所里有霉菌问题，可能会发现房东或服务式公寓管理方并没有特别重视这个问题。很多情况下，常见的处理方式只是把发霉的地方重新刷漆或遮盖起来。但这并没有真正解决根本原因，霉菌往往还会再次出现。
Mold is not always just a surface problem. Behind visible mold, there may be hidden moisture, water-damaged materials, poor ventilation, or high indoor humidity. That is why professional mold service should start with onsite investigation, not just spraying or painting.
霉菌不一定只是表面问题。看得见的霉斑背后，可能是墙体潮湿、材料受潮、通风不足，或室内湿度长期过高。所以，专业的霉菌服务不应该只是直接喷药或刷漆，而应该先从现场勘测和排查开始。
If mold is found in your home, you may need to consider how serious the problem is and whether the place is still suitable for long-term living. Professional mold testing and treatment can be a serious investment. Based on Greenwave’s experience, a basic solution may cost around RMB 5,000 to 10,000. If the mold issue is serious, the cost may be much higher and can reach over RMB 100,000 in complex cases.
如果家里发现霉菌，您可能需要先判断问题的严重程度，以及这个住所是否仍然适合长期居住。专业霉菌检测和治理并不便宜。根据Greenwave的服务经验，基础处理方案可能需要约人民币5,000到10,000元。如果霉菌问题严重，费用可能会更高，复杂情况甚至可能超过人民币100,000元。
For people renting a home, it is better to check for mold before signing the contract. You may also consider adding terms to the rental agreement, such as what should happen if mold is found, who is responsible for fixing it, and whether compensation or moving-out support should be provided.
对于租房用户来说，最好在签订租赁合同前就检查是否存在霉菌问题。也可以考虑在合同中加入相关条款，例如如果发现霉菌，房东是否需要负责修复，或者是否需要提供搬离补偿等安排。
Mold testing is useful, but onsite investigation is often even more important. A professional inspection is not just “looking at the wall”. It helps understand where the moisture comes from, whether materials are already damaged, whether there are hidden mold risks behind furniture or cabinets, and whether the building environment may cause the mold to return.
霉菌检测有帮助，但现场勘测往往更加关键。专业排查不只是“看一眼墙面”。它可以帮助判断潮湿来源在哪里，材料是否已经受潮受损，家具或柜子背后是否存在隐藏霉菌风险，以及房屋环境是否容易导致霉菌反复出现。
If needed, samples can also be collected and sent to professional laboratories for testing. The report can help identify the type and concentration of mold and support a more suitable treatment plan.
如有需要，也可以采集样本并送往专业实验室检测。检测报告可以帮助了解霉菌类型和浓度，并为后续治理方案提供参考。
A professional mold investigation may include visual inspection, moisture checking, temperature and humidity measurement, air sampling, surface sampling, and inspection of high-risk areas. Common risk areas include bathrooms, basements, kitchens, storage rooms, wardrobes, window corners, and areas behind furniture or appliances. The purpose is not only to confirm whether mold exists, but also to understand why it happened and how to reduce the chance of it coming back.
专业霉菌勘测可能包括现场查看、湿度检测、温湿度测量、空气采样、表面采样，以及重点风险区域排查。常见风险区域包括卫生间、地下室、厨房、储藏间、衣柜、窗边角落，以及家具或家电背后。勘测的目的不只是确认是否有霉菌，更重要的是判断它为什么出现，以及如何降低之后反复发霉的可能性。

Professional mold remediation should be a controlled process. The goal is not only to remove visible mold, but also to reduce cross-contamination, protect indoor items, clean particles, and treat affected surfaces properly.
专业霉菌治理应该是一个受控流程。目标不只是清除看得见的霉斑，还包括减少交叉污染、保护室内物品、清理颗粒物，并对受影响表面进行系统处理。
Greenwave’s remediation process may include cross-contamination barriers, electronics protection, HEPA vacuuming, wet wiping on non-porous surfaces, chlorine dioxide fogging, and a second round of HEPA vacuuming after treatment. In some cases, dehumidifiers may also be needed to control indoor humidity and help reduce the chance of mold returning.
Greenwave的治理流程可能包括防交叉污染保护、电子产品保护、HEPA高效吸尘、非多孔表面湿巾擦拭、二氧化氯喷雾消杀，以及治理后的二次HEPA吸尘。在部分情况下，也可能需要配合除湿机来控制室内湿度，降低霉菌反复出现的可能性。
Greenwave’s mold remediation follows industry-accepted guidelines from the BSR-IICRC S520 Standards and Reference Guide for Professional Mold Remediation.
If mold keeps coming back, the root cause may not have been solved. Common reasons include hidden leakage, damp walls, high humidity, poor ventilation, surface-only cleaning, or treating the wrong area. That is why mold remediation should not only focus on removing visible mold. It should also include moisture control, ventilation improvement, and follow-up prevention suggestions.
如果霉菌反复出现，通常说明根本问题还没有解决。常见原因包括隐藏漏水、墙体潮湿、湿度过高、通风不足、只做了表面清洁，或真正的发霉源头没有被找到。所以，霉菌治理不能只关注看得见的霉斑，还需要结合湿度控制、通风改善和后续防复发建议。
Greenwave provides mold investigation and remediation services for homes and commercial spaces. Our service can include onsite inspection, air and surface sampling, moisture and humidity checking, report-based recommendations, professional remediation, and follow-up prevention advice.
