改造类型
在下一次地震或风暴来临前，为你的家加固支撑。
BedrockMatch 是一项免费的服务，会把房主与经过筛选的本地地震与风暴改造承包商联系起来。了解改造究竟能解决什么、通常需要花多少钱、像 Brace + Bolt（加固支撑与锚栓）这类补助可能能覆盖哪些费用——并对比承包商。房子由你所有，你决定选谁来做。
对房主始终免费 固定费用的匹配 不从工程费用中抽成
BedrockMatch 是免费的匹配服务，而不是承包商或工程师。对房主的匹配免费；我们从不从工程费用中抽成。你来对比并选择由谁来做。
改造前：未上螺栓、未加支撑
房屋框架可能会从地基上滑移；薄弱的矮墙会发生弯曲或失效。
改造后：已上螺栓并加固支撑
锚栓和胶合板支撑把房屋牢固地连接到地基上。
你家有风险吗？
你家有风险吗？
几个简单的问题，帮助你找出最值得向承包商咨询的改造方向。这是一般性建议，不是现场检查。
Was your home built before the 1980s on a raised foundation with a crawl space?
为什么重要: Older raised-foundation homes are often not bolted down and have unbraced cripple walls.
Does your home have a garage or open space under living rooms (a 'soft story')?
为什么重要: A weak open ground floor can collapse sideways in a strong quake.
Do you live in an earthquake, hurricane, or high-wind region?
为什么重要: Where the hazard is higher, retrofitting matters more — and grants are more likely.
Do you have an unreinforced masonry chimney or an unstrapped water heater?
为什么重要: These are cheap to brace and prevent fire, gas leaks, and falling-debris injuries.
Has your home never had a structural retrofit or seismic upgrade?
为什么重要: If no one has bolted, braced, or tied it down, the original weak points are still there.

改造能解决什么问题
改造到底能修复什么
房屋常见的薄弱点，以及针对每一处薄弱点的加固工作。具体哪些适用取决于你的房子；持牌承包商会在现场查看后确认。
Cripple-wall bracing
能做什么Adds plywood bracing to the short stud walls between the foundation and the first floor so they don't buckle.
哪些房屋需要Houses with a crawl space and unbraced 'cripple' walls — a very common weak point in older homes.
Soft-story strengthening
能做什么Reinforces a weak ground level — usually an open garage or carport under living space — with a steel frame.
哪些房屋需要Homes and small apartment buildings with a tuck-under garage or large open first floor.
Hurricane straps & roof tie-downs
能做什么Metal connectors tie the roof to the walls and the walls to the foundation so high winds can't peel them off.
哪些房屋需要Homes in hurricane, high-wind, and severe-storm zones, especially older wood-frame houses.
Chimney & water-heater bracing
能做什么Braces an unreinforced masonry chimney and straps the water heater so they don't topple or rupture a gas line.
哪些房屋需要Almost any older home — these are low-cost fixes that prevent fire, gas leaks, and falling-debris injuries.
Garage & wall reinforcement
能做什么Adds shear panels and hold-downs at weak wall lines so the structure resists side-to-side shaking and wind.
哪些房屋需要Homes with large openings, wide windows, or additions that left a wall line under-supported.
真实的费用范围
诚实的改造成本区间
仅为常见范围——不是报价。你需要支付多少取决于你的房子、所在地区，以及承包商确认的改造范围。像加州的“地震加固 + Bolt（地震加固 + Bolt）”这类补助可能有助于支付改造费用。
| 项目 | 常见范围 |
|---|---|
| Foundation bolting (anchor bolts only) | $1,500 - $4,000 |
| Cripple-wall bracing + bolting (typical house) | $3,000 - $7,000 |
| Full seismic retrofit (older raised-foundation home) | $5,000 - $10,000 |
| Soft-story strengthening (steel frame) | $10,000 - $80,000+ |
| Hurricane straps & roof tie-downs | $1,000 - $5,000 |
| Chimney bracing / water-heater strapping | $200 - $3,000 |
| CA Earthquake Brace + Bolt grant (toward the work) | up to $3,000 if you qualify |
许多州和 FEMA（美国联邦紧急事务管理署）项目都提供改造补助或保险折扣。询问你的房子是否符合条件。
