Hydraulic Jacking · Timber Cribbing · Flood Elevation · New FoundationLifting a house is priced by its ground-floor footprint—not total upstairs square footage—and splits into two major contracts: the structural hydraulic lift on steel I-beams and timber cribbing ($18,000–$48,000) and building the new foundation, stairs, and utility connections underneath ($25,000–$95,000+).

Diagram, part by part
The cost to raise a house drawing above has 9 numbered parts, from Steel beams & jacking to Moving out during the lift. Each card below frames one of them, and after you run the calculator it shows what that part adds to your estimate.
$18,000–$48,000
Steel I-beams are slid through the foundation under the floor framing, and a unified hydraulic jacking system lifts every point at the same rate so the house rises level without cracking walls. This is the core of the job and the main structural cost.
What moves it: House weight, number of stories, brick veneer and the lift height.
On the quote: Ask whether the lift uses unified hydraulic jacks and for proof of the contractor's structural moving insurance.
Part of the lift price
Stacked timber cribbing towers hold the house in the air while the new foundation is built underneath. They are added in stages as the house rises and stay in place for weeks.
What moves it: Lift height and how long the foundation work takes.
On the quote: Ask how long the house stays on cribbing and how it is braced against wind.
$14,000–$55,000
New footings and taller block or poured walls are built under the raised house, then the house is lowered onto them. In flood zones the walls include flood vents so water can pass through instead of pushing on the foundation.
What moves it: Foundation type, wall height and soil.
On the quote: Ask for the engineered foundation drawing and the footing size and depth.
Inside the engineering line
Water, sewer, gas and electric are disconnected before the lift and reconnected and extended to the new height afterwards. HVAC equipment and ducts below the flood line are usually moved up too.
What moves it: Number of utilities and how far they must be extended.
On the quote: Ask who coordinates with each utility and whether HVAC relocation is included.
$4,500–$18,000
Stairs, porches, decks and ramps must be rebuilt to reach the new floor height. A tall lift may need a landing, railings and in some cases a new entry design.
What moves it: Lift height and the number of entries.
On the quote: Confirm these are in the quote, since they are often left out of the lift price.
$2,800–$7,500
A structural engineer designs the lift and the new foundation, and permits follow local floodplain rules. In flood zones an elevation certificate shows the new floor height for insurance.
What moves it: Flood zone, project size and your town's rules.
On the quote: Ask whether FEMA or Increased Cost of Compliance funding applies and who prepares the elevation certificate.
2 to 14 feet
A short lift of a few feet clears a local flood level or fixes a sill; a full-story lift creates a garage or basement below; coastal lifts of 10 to 14 feet sit on driven piles. Building one or more feet above the base flood elevation, called freeboard, can lower flood insurance premiums.
What moves it: Your flood zone, the base flood elevation and what you want underneath.
On the quote: Ask for the target floor height in feet above the base flood elevation.
Included with a crawlspace foundation
Enclosures below the floor in a flood zone need engineered flood vents so water levels equalize on both sides of the wall. In coastal V zones, the lower walls must be designed to break away without damaging the house.
What moves it: Foundation type, wall length and flood zone.
On the quote: Ask for the number and type of flood vents and whether they are certified.
Not in this estimate
Most homeowners move out for several weeks to a few months while the house is on cribbing and utilities are off. Temporary housing and storage are not part of the contractor's price but belong in your budget.
What moves it: Project length and local rents.
On the quote: Ask for a written schedule showing how long the house will be unlivable.
Hydraulic lift vs turnkey foundation
A structural house-moving company prices the steel beams, unified hydraulic jacking, and timber cribbing that lift the house into the air—and then lowers it back down. Excavating, pouring footings, laying the new foundation walls, extending plumbing/electrical lines, and rebuilding entry stairs are separate general-contractor trades.
Three close-ups from the photo above, and what each one means for a cost to raise a house quote. These close-ups are crops of the same AI-generated illustration.
An 1,800 sq ft two-story colonial sits on a 900 sq ft ground footprint. Two stories add weight (increasing the steel beam and hydraulic jacking rate by ~28%), but do not double the foundation perimeter.
Modern house lifters use a central hydraulic manifold that raises every jack at the exact same pressure so drywall, windows, and roof ridges do not rack or crack during the lift.
In FEMA Zone AE/VE floodplains, enclosed areas below the Base Flood Elevation must have engineered hydrostatic flood openings (1 sq in per sq ft) and a surveyor's final Elevation Certificate to cut NFIP premiums.
homeowners raise a house for one of two reasons: floodplain elevation (lifting the lowest floor 2 to 9 feet above the FEMA Base Flood Elevation in Zone AE or coastal Zone VE) or adding a full lower story / walkout basement underneath an existing home. FEMA P-312, the Homeowner’s Guide to Retrofitting, explains how each elevation method works; for cost, this calculator uses 2026 planning ranges. Turnkey costs for a 1,200 sq ft ground-footprint home fall into four tiers:
| Project Scope & Foundation Type | Cost per Sq Ft of Footprint | 1,200 Sq Ft Footprint Total | What Is Included |
|---|---|---|---|
| Hydraulic Lift & Cribbing Only (Subcontractor Bid) | $15 – $35 / sq ft | $18,000 – $42,000 | Beam pockets, steel I-beams, unified hydraulic lift (2–6 ft), timber cribbing & set-down only |
| 3–5 Ft Flood Lift + New CMU Block Crawlspace | $35 – $72 / sq ft | $42,000 – $86,400 | Lift + new footings, reinforced block walls, FEMA flood vents, utility extensions & entry steps |
| 8–10 Ft Full Story Lift + Poured Concrete Basement | $62 – $120 / sq ft | $74,400 – $144,000 | High lift + full 8–9 ft poured foundation or garage under-story, slab, stairs & mechanicals |
| Slab-on-Grade Lift or Coastal Driven/Helical Piles | $75 – $145+ / sq ft | $90,000 – $174,000+ | Sub-slab tunneling or lifting concrete slab intact, or deep timber/helical piles in coastal V-zones |
When comparing bids, check whether you are looking at a structural mover's rigging quote or a general contractor's turnkey contract. A complete house elevation requires six distinct cost buckets:
| Cost Bucket | 2026 Typical Range | Key Scope Details to Verify in Writing |
|---|---|---|
| 1. Structural Engineering (PE), Survey & Permits | $2,800 – $7,500 | Soil borings, PE stamped lift/foundation plans, pre- and post-lift Flood Elevation Certificates |
| 2. Utility Disconnects, Extensions & Reconnects | $3,500 – $11,000 | Plumbing waste/water risers, gas meter line, 200A electric mast, and elevated HVAC condenser platform |
| 3. Unified Hydraulic Jacking & Steel Beam Rigging | $18,000 – $48,000 | Threading main & needle steel beams, unified jacking to height, holding on 6×6 oak cribbing, and lowering onto new sill plates |
| 4. Demolition, Footings & New Foundation Walls | $14,000 – $55,000 | Rebar footings, grouted CMU block or poured concrete walls, hurricane anchor straps, and engineered smart flood vents |
| 5. Exterior Stairs, Porches, Decks & Chimneys | $4,500 – $18,000 | Every foot you raise the house adds roughly 1.5 stair risers at every exterior door; masonry chimneys must be extended or removed |
A two-story wood-frame house with 2,400 sq ft of total living space sits on a 1,200 sq ft ground-floor footprint. It is lifted 4 feet in a FEMA Zone AE floodplain onto a new reinforced CMU block foundation:
| Line Item | 2026 Planning Range |
|---|---|
| Hydraulic lift, steel I-beams & timber cribbing (1,200 sq ft × 2-story weight factor) | $19,600 – $44,500 |
| New reinforced crawlspace foundation walls & FEMA flood vents | $14,400 – $33,600 |
| Structural PE engineering, elevation certificates, utility reconnects & permits | $5,000 – $14,000 |
| Turnkey planning total (before new decks/stairs) | $39,000 – $92,100 |
Remember to budget separately for new code-compliant front and back entry stairs ($3,500–$12,000) and any interior finishing if you are raising the house a full 8 to 9 feet to create a new ground-floor garage or basement.
Standard HO-3 homeowners insurance never covers preventive house raising, flood elevation, or foundation settling. However, if your home is in a mapped Special Flood Hazard Area (SFHA), two federal funding programs can offset the cost:
The calculator's default house raising job, repriced for each of its six regions. At the national average it runs $33,800 – $78,800; South / Lower Midwest is the lowest at $29,406 – $68,556, and West Coast metro is the highest at $43,940 – $102,440, a gap of about $24,209 at the midpoint.
| Region | Planning range | Midpoint |
|---|---|---|
| National average | $33,800 – $78,800 | $56,300 |
| South / Lower Midwest | $29,406 – $68,556 | $48,981 |
| Mountain / Plains | $32,110 – $74,860 | $53,485 |
| Mid-Atlantic / Upper Midwest | $37,856 – $88,256 | $63,056 |

| West Coast metro | $43,940 – $102,440 | $73,190 |
Every other input stays at its default and only “New foundation work” changes. The cheapest choice, Lift & cribbing only (foundation priced separately), comes to $19,400 – $45,200; the most expensive, Driven timber or helical steel piles (coastal), comes to $57,800 – $126,800.
| Choice | Planning range | Midpoint vs default |
|---|---|---|
| Lift & cribbing only (foundation priced separately) | $19,400 – $45,200 | −$24,000 |
| New reinforced CMU block crawlspace + flood vents (default) | $33,800 – $78,800 | — |
| Full 8–9 ft poured basement or drive-under story | $48,200 – $111,200 | +$23,400 |
| Driven timber or helical steel piles (coastal) | $57,800 – $126,800 | +$36,000 |
Every other input stays at its default and only “Lift height” changes. The cheapest choice, Short lift, 2–4 ft (flood clearance or sill repair), comes to $33,800 – $78,800; the most expensive, High coastal lift, 10–14 ft (driven pilings / V-zone), comes to $43,160 – $99,080.
| Choice | Planning range | Midpoint vs default |
|---|---|---|
| Short lift, 2–4 ft (flood clearance or sill repair) (default) | $33,800 – $78,800 | — |
| Full story lift, 8–9 ft (new basement or garage below) | $39,272 – $90,656 | +$8,664 |
| High coastal lift, 10–14 ft (driven pilings / V-zone) | $43,160 – $99,080 | +$14,820 |
House raising quotes should show the lift, the foundation and the work around it.
| Stage | Typical time | What happens |
|---|---|---|
| Engineering and permits | 1 – 3 months | Including floodplain review. |
| Prep and utilities off | 1 – 2 weeks | Moving out begins. |
| Lift | 1 – 3 days | House raised onto cribbing. |
| New foundation | 2 – 6 weeks | Built under the house. |
| Lower, reconnect and stairs | 2 – 4 weeks | Then final inspection. |
Ask about grant programs before signing; flood mitigation funds often require approval before work starts.
Lifting a wood-frame house 3 to 5 feet and building a new reinforced crawlspace foundation underneath typically costs $35 to $75 per square foot of ground footprint ($42,000 to $90,000 for a 1,200 sq ft footprint), including hydraulic jacking, foundation masonry, engineering, permits, and basic utility reconnections. Lifting a house a full 8 to 10 feet or elevating a concrete slab-on-grade home runs $75,000 to $160,000+.
Always by the ground-floor footprint (plus any attached garage or porch being lifted). A 2,200 sq ft two-story colonial with a 1,100 sq ft first floor is priced on 1,100 sq ft, with a 25% to 30% weight multiplier on the hydraulic jacking line for the second story.
Yes, using one of two specialized methods: either sawing the anchor bolts and lifting the wood/brick frame off the old slab (then pouring a new elevated floor deck), or excavating tunnels under the slab to thread steel beams and lift the entire concrete slab and house together. Slab lifts cost 35% to 60% more than crawlspace or basement lifts.
The actual hydraulic jacking takes only 1 to 3 days once the steel I-beams and cribbing are in place. However, excavating, pouring footings, laying the new foundation walls, curing concrete, lowering the house, reconnecting utilities, and building new stairs typically takes 4 to 10 weeks total.
If you carry an NFIP flood policy and a flood causes Substantial Damage (repairs reaching 50% or more of your home's structure value), NFIP Increased Cost of Compliance (ICC) pays up to $30,000 toward elevation. Separate FEMA FMA and HMGP mitigation grants can cover 75% to 100% of elevation costs for repetitive-loss properties applied for through your town floodplain administrator.
Elevating the lowest floor 2 to 3 feet above the FEMA Base Flood Elevation (BFE) with certified engineered flood vents and a new Elevation Certificate frequently reduces annual flood insurance premiums by 50% to 80% ($1,500 to $4,500+ saved per year).
No. The lift is the cribbing, the steel and the day the house comes up. The foundation is the new piers, crawl space or basement it lands on. This calculator prices both, because a lift without a foundation is not a finished job.
Usually not as a project you chose. After a covered flood, some policies with ordinance or law coverage pay the extra cost to meet a current elevation rule. A standard homeowners policy does not pay to lift a dry house. Flood insurance is a separate policy and has its own limits.
Contents moving, months of rent, stairs, skirting, a new first-floor build-out if you lift a full story to create living space, and soil that will not hold a pier without extra engineering.
Cost to raise a house jobs rarely stop at one trade. These are the calculators people open next.
