对于租房族而言，押金退还一直是令人头疼的难题。数据显示，近60%的租客因房屋损坏问题未能全额收回押金。其实许多看似严重的损坏，只需低成本DIY修复就能避免扣款。

针对常见房屋损坏，专家推荐以下实用修复技巧：

• 木质表面划痕：使用配色蜡笔和木材修补笔即可轻松遮盖刮痕
• 墙面孔洞：小孔可用3M补墙膏填补，大洞适用免打磨腻子填充
• 纱窗破损：购买修复工具包自行更换网面，成本不足百元
• 油漆剥落：用地漆修补笔精准补色，尤其房东偏爱的标准白色
• 地毯污渍：专用清洁剂可去除红酒、油渍等顽固污痕
• 台面开裂：使用SeamFil等复合材料可完美修复层压板破损
• 玻璃裂纹：双组分环氧树脂能隐形修补窗户细小裂痕
• 管道堵塞：塑料疏通工具能快速清除毛发堵塞物

专业人士提醒，租户应区分正常使用损耗与人为损坏，简单维修不仅能保全押金，更是对房屋设施的负责任态度。建议退租前预留两周时间逐步检修，若遇复杂问题仍应联系专业施工人员处理。

如果你租过房子，就会知道有项额外开支让租房成本更高：押金。通常押金金额基于月租金计算，平均押金为750美元（约合5430元人民币），对大多数人来说这不是小数目。理论上退租时能拿回这笔钱（有时还含利息），但近60%的租客预计无法全额收回押金，主要原因在于房屋损坏。

所有房屋都会因居住产生自然"磨损"。物品会陈旧老化，这是正常现象而非人为过错。但若造成超出"磨损"范畴的损坏，房东会很乐意从押金中扣除维修费用。其实只需花点小钱做些简单修复，多数情况下都能避免扣款。

木制品修复
实木地板划痕？橱柜磨损？若担心房东要求更换或翻新，一套蜡条和木材修补笔就能轻松掩盖瑕疵。用颜色匹配的蜡条填充浅凹痕，再用同色修补笔描画划痕，稍加耐心就能让损伤几乎隐形。

墙面修补
石膏板价格低廉且实用，但极易受损。有时失去平衡或距离判断失误，墙上就可能出现破洞。房东往往会声称需要施工队修复，但其实可以快速低价自行解决：小洞用3M多功能修补膏，涂抹刮平晾干后打磨即可；大洞用石膏板修补腻子，滚压填充后擦除多余部分，晾干后上漆即完成。

纱窗更换
纱窗破损不仅会招虫蚁，还可能被要求赔偿。幸运的是更换纱窗非常简单：购买维修套件（已有工具可单买网布），抽出固定压条，更换新网布后压回压条即可。套件通常含新压条，原有压条有时也可重复使用。

补漆工艺
墙面、橱柜或电器漆面磨损可能被扣押金。无需整体重刷，只需用补漆笔局部修复。标准"房东白"最容易匹配，其他色号也可找到相应产品。冰箱等电器则需专用补漆笔处理。

地毯去渍
宠物污渍或红酒洒落若不处理会惹恼房东。即便油渍也能用去渍剂神奇去除：无需吸尘或擦拭，涂抹轻搓后吸干，多数污渍即刻消失。

地毯修补
无法清除的污渍或严重损伤可尝试修补。房东常在屋内或储物间留有余料，找到匹配地毯后，切除损坏部分，用双面地毯胶带粘贴修补块，小面积修补几乎看不出痕迹且十分耐用。

复合板修复
台面或地板 laminate 材料开裂？使用SeamFil等凝胶状修补产品，干燥后能与原材质完美融合。注意选择相近颜色，并按说明使用专用溶剂清洁以获得最佳效果，这会略微增加成本。

玻璃修复
窗户裂纹可用双组分环氧树脂修补。像腻子般填入裂缝，干燥后透明且能强化玻璃。若修补范围小，几乎难以察觉。

管道疏通
下水道堵塞是扣押金的常见原因。塑料疏通工具价格低廉且高效，能轻松清除毛发团块，让排水恢复流畅迎接房东验收。

If you rent your home, you know there’s one extra barrier that makes affording the place even harder: The security deposit. Typically based on the monthly rent amount, the average security deposit is $750, which is a lot of money for most folks. In theory, you get that money back—sometimes with interest—when you move out. But nearly 60% of renters don’t expect to get the full amount of their security deposit back, and a big reason is damage to the home.
Every home experiences normal “wear and tear” from being occupied. Things get worn, old, and used up, and that’s nobody’s fault. But if you’ve caused damage to the place that falls outside the “wear and tear” concept, your landlord will be more than happy to deduct the cost of that repair from your deposit. But you can avoid that in a lot of cases by spending a small amount of money on a simple repair that just about anyone can do.
Wood repair
Scratched wood floors? Scuffed-up cabinets? If you’re worried that your landlord might regard those scratches as damage that requires replacing or refurbishing the wood in the apartment, a set of wax sticks and wood markers is a cheap way to hide all that damage. With a little patience, you can fill in shallow gouges with a color-matched wax stick and draw over scratches with a color-matched marker to produce a repair that makes these imperfections almost invisible.
Drywall putty
Drywall is amazing stuff. It’s cheap, but it does its job of being a wall perfectly well. But it’s also pretty easy to damage. All it takes is losing your balance or misjudging distances and bam! You’ve put a hole in your wall. A hole your landlord will probably claim requires a team of workers to repair.
But you can fix it really quickly, and really cheaply. For smaller holes, this all-in-one patch from 3M is pretty magical: Just apply the spackle, use the back of the applicator to scrape it flush with the wall, let it dry, then use the supplied sanding cap to sand it smooth. Then paint (if necessary) and you’re golden!
For larger holes, this drywall repair putty is incredibly easy to use. You just roll it over the hole to fill it in, wipe away excess, let it dry, then paint. You won’t need to sand or do anything else to it.
Window screens
Did you poke through a window screen? Aside from letting all the bugs into your home, you’re now faced with the possibility that your landlord will charge you for a replacement. Luckily, replacing a window screen is one of the easiest repair jobs you can do. Just buy a window screen repair kit (you can just get the screen material if you’ve already got some tools that can do the job). Replacing the screen is just a matter of pulling out the spline (the caulk-like rope that holds the screen in the grooves of the frame), removing the damaged screen, cutting a fresh piece to fit, and pushing it into the grooves with the spline to hold it in place. You can sometimes reuse the existing spline, but the kits will provide fresh spline for you to use.
Touch up paint
If you’ve scuffed and chipped the paint on the walls, cabinetry, or appliances in your apartment, you might get dinged in your security deposit if the damage is too obvious. But you don’t need to re-paint the world to save your deposit, you just need a little touch-up paint. This will be most effective if your apartment is done in standard Landlord White, but you can find other shades of touch-up paint if you look. Just cover the chips where you find them and let it dry. If you’ve somehow damaged the fridge or dishwasher finish, you can buy appliance-specific touch up paint that can repair small bits of damage very effectively.
Carpet stain remover
If you smuggled your dog into the apartment, or tripped and dumped an entire glass of red wine onto the carpet and never bothered to deal with the stains and odors, your landlord will not be amused. While getting stains and odors out of carpet can be a challenge, a bottle of spot remover can work some real magic, even on greasy stains. This stuff doesn’t require vacuuming or wiping down—just apply, agitate a little, and blot, and most stains will simply vanish.
Carpet patch
If you can’t get that stain out of the carpet, or you’ve damaged a spot so badly that it can’t be repaired or hidden, you might be able to patch the carpet—if you have any spare carpet to work with. Landlords will sometimes leave extra carpet in the apartment or in the storage area of the building, so start with a little investigation. If you strike gold and find a portion of carpet remnants that match, you can cut out the damage area, cut a patch to fit, and use some double-sided carpet tape to fix it into place. For a relatively small section, this repair will blend surprisingly well, and be surprisingly durable.
Laminate repairs
Did you crack or chip the laminate countertops or floors in your rental? Don’t panic: For small bits of damage, you can use a product like SeamFil, which applies like a gel or cream and dries to a perfect bond with the existing laminate. With a little patience and care, you can wind up with a repair that’s almost impossible to spot. Just make sure to color match as closely as you can, and keep in mind that the company recommends using its SeamFil Solvent to clean the area before applying the filler for best results, which can increase the overall cost of the repair.
Window repairs
I once cracked a window trying to hang holiday lights around it, and the crack taunted me for years before I finally got the windows replaced in the house. If you don’t want to pay for a whole new window when you move out, you might be able to repair a small crack yourself by using a two-part epoxy like this to fill in and hide the crack. Epoxies like this get worked into the crack like putty, dry clear, and reinforce the glass. If the repair is small, you have a good chance of no one ever noticing.
Unclogging drains
A surprisingly common reason landlords hit up security deposits are clogged drains. Sure, clogs can lead to floods and water damage (and can eventually damage the plumbing itself), but they’re super easy to deal with, usually. If you haven’t thought about how slow the drains in your house have become over time, it’s not too late: A set of plastic drain clearing tools is incredibly cheap, easy to use, and very effective at dragging a (probably disgusting) clump of hair and out of your drains, making them seem like new just in time for your landlord’s inspection.
