Start with the honest part. Despite Houston being one of the largest foundation repair markets in the country — expansive clay under essentially the entire metro, half a million-plus slab homes past their thirtieth year — there is no published Houston or Texas cost-per-lead figure for foundation repair anywhere. Not from the marketplaces, not from the agencies, not from the trade.
What follows is assembled from national channel data, Houston job values, and the arithmetic that connects them. Where a number is an inference rather than a measurement, it says so.
What a foundation repair lead costs
| Channel | Cost per lead | Reported close rate | Notes |
|---|---|---|---|
| Google Ads, search | $152–$180 | 25–30% | Target CPA starting points of $190–$210 are commonly recommended |
| Google Ads, wider band | $150–$400 | 20–30% | Qualified leads; $8–$18 per click |
| Google Local Services Ads (LSA) | $60–$75 | — | See the eligibility note below |
| Angi / HomeAdvisor | $35–$120 | 5–15% | Sold as “Foundation/Concrete”, shared 3–8 ways |
| Networx | $10–$100+ / $15–$120+ exclusive | not published | Published rate card, all trades |
| Facebook / Meta | ~$41 (category proxy) | — | No foundation-specific figure published |
Published sources disagree on whether foundation repair has its own Local Services Ads category. Some category lists include “Foundations”; others omit it entirely, and contractors in adjacent trades routinely end up advertising under General Contractor instead — which dilutes intent badly.
There is also a documented catch where it does run: LSA foundation leads reportedly skew toward smaller repair jobs rather than full pier projects. A $70 lead that produces crack-injection inquiries is not the same product as a $180 lead that produces pier quotes. Check Google’s live category list for your own account before budgeting around it.
Houston foundation job values
| Item | Houston figure |
|---|---|
| Average job | $5,003 (range $3,276–$6,729) |
| Typical spend band | $4,500–$9,000 |
| Pier count, 2,000 sq ft home | 20–30 (6–10 for one-side settling) |
| Pressed concrete piling | $150–$400 each |
| Pressed piling with steel insert | $375–$700 each |
| Bell-bottom pier | $500–$700 each |
| Crack injection | $250–$800 per crack |
| Drainage correction | $2,000–$6,000 |
| Houston labor / permit | $120–$200/hr · $33.10 permit |
One warning about online pier pricing: the $1,200–$3,500 per-pier figures that dominate search results are steel push and helical piers sold by national brands. That is not how the Houston market quotes. Pressed concrete pilings at $150–$400 are the local norm, and quoting national per-pier numbers to a Houston contractor immediately marks you as someone who read a blog post.
Two different seasons, and they do not line up
Foundation repair in Houston has a demand curve and a delivery curve, and they are out of phase.
The symptom curve peaks in summer
Spring rains lift the slab; summer heat dries the clay and drops it back down. Houston Black Clay can shrink substantially as it dries, against roughly fifty inches of annual rainfall. The result is a sharp rise in calls from about June onward — reopening cracks, sticking doors, sloping floors — running through the dry end of summer.
The repair curve favors spring and fall
Spring and fall are the workable windows, when the soil is neither baked hard nor saturated. Summer heat can raise labor cost and cause delays; winter ground is muddy and prone to heaving. Which means the buy-side spike arrives in the months you are least able to install into, and schedules fill fastest in the shoulders.
Practically: your lead cost inflates in mid-to-late summer while your conversion is constrained by backlog. If you are buying leads on a per-lead meter, that is the worst possible pairing — paying peak prices for inquiries you cannot service for six weeks. The National Weather Service Houston drought page is a genuinely useful leading indicator for when it is about to start.
What a foundation lead is worth
This trade has the strongest lead economics on the list, and it is not close.
10 qualified calls per month × 25% close × $6,750 average job × 50% gross margin = $8,437 per month in gross profit.
A lead source is generally worth 15–25% of the gross profit it generates — here, $1,265 to $2,109 a month.
Compare that to what the leads cost. Ten Google Ads leads at $152–$180 is $1,520–$1,800 a month at a 25–30% close, producing two or three jobs. Ten shared marketplace leads at $80 is $800 a month at a 5–15% close, producing perhaps one. The cost per booked job on the shared route runs to roughly $800–$1,600; on qualified exclusive traffic it lands nearer $500–$700.
At a $5,000 average ticket, either can work. That is the luxury of a high-value trade. But at 10 leads a month rather than 40, the variance is brutal — a quiet month with two dud leads is a quiet month, full stop. Low-volume, high-value trades are precisely where a per-lead model feels most like gambling and a fixed monthly cost feels most like a business expense.
Common questions
Why is there no published foundation lead cost for Houston?
Because the marketplaces do not break it out and the agencies that publish benchmark data concentrate on the high-volume trades. Foundation gets folded into “Foundation/Concrete” on marketplace rate cards and into “Construction & Contractors” on ad benchmarks, both of which average it with much cheaper work.
Do foundation leads convert better than other trades?
On qualified search traffic, reported close rates of 25–30% are above the home-services norm — a homeowner searching “foundation repair” usually has visible symptoms and an engineer’s report or a real-estate deadline. Marketplace leads in this trade behave like marketplace leads everywhere else.
How many leads a month does a Houston foundation contractor need?
Fewer than you would think, which is the point. At $6,750 average and 25% close, ten qualified calls a month is roughly $200,000 a year in revenue. The scarce input is not volume — it is exclusivity, because two contractors chasing the same slab means one of them just wasted a site visit.
About these figures. Houston job values are consumer cost survey data cross-checked against local contractor pricing pages. Cost-per-lead figures are national, from 2026 agency-published benchmarks, and are directional — no measured foundation-specific dataset with a disclosed sample exists. Gross margin for this trade is a working prior, not a survey finding. Seasonality is drawn from Houston clay-soil behavior and local contractor scheduling guidance rather than measured call-volume data.
