Crack-X vs Arta Foundation Repair

These two are close enough that the honest answer is "it depends on the job." Crack-X and Arta Foundation Repair are both well-rated New Hampshire foundation specialists of similar size, roughly 50 Google reviews apiece, working the Manchester and Londonderry area. Their five-star shares are effectively tied: Crack-X sits at 92.2% (47 of 51) and Arta at 92.3% (48 of 52), per each company's Google profile (2026). The gauge below highlights Arta because it leads by a single tenth of a point, but a tenth of a point across about 50 reviews is a tie, not a win, and we will not pretend otherwise. The real decision is scope. For one foundation crack or a leaking bulkhead, our pick is Crack-X. For foundation repair bundled with concrete leveling or water control, our pick is Arta. Here is the reasoning, with sources.

Our findings follow our published methodology. Every figure below is dated and sourced.

At a glance

What homeowners report

We read the full Google rating distribution for both companies, not just the headline star average, because two 4.8-star listings can hide different stories underneath. The first thing to say plainly: both review bases are small. Crack-X has 51 Google reviews and Arta has 52 (Crack-X on Google; Arta on Google, 2026). That is enough to show a pattern, but not the deep, hundreds-deep signal a homeowner gets from a high-volume listing. Weight both accordingly, and read the recent reviews yourself.

On the headline number, this is a tie. Crack-X shows 47 five-star ratings out of 51, a 92.2% five-star share. Arta shows 48 five-star out of 52, a 92.3% share (Crack-X on Google; Arta on Google). The gauge marks Arta as higher, but the gap is one tenth of one percent, which is a single review either way. Call it level.

Where the two distributions actually differ is at the bottom. Crack-X has zero one-star reviews; its worst ratings are two two-star and one three-star out of 51. Arta has two one-star reviews out of 52, roughly one in 26 (Crack-X on Google; Arta on Google). Neither pattern is alarming on a base this size, and a single unhappy customer moves the proportion a lot when the total is around 50. But if you are weighing the floor of each record, Crack-X has no one-star ratings on the listing we recorded, and that is worth noting honestly without overreading it.

The review themes match what each company actually does, which is the more useful signal at this volume. Crack-X's top topics are courteous staff (12 mentions), foundation crack repair (11), bulkhead build (5), warranty (5), responsiveness (5), and water leak repair (3) (Crack-X on Google). That cluster reads like a focused crack-and-bulkhead shop, and the five separate warranty mentions are notable for a company this size. Arta's top topics are knowledgeable staff (13), sump pump installation (10), foundation repair (10), reasonable pricing (9), foundation issues (4), and project completion (3) (Arta on Google). The "reasonable pricing" and "knowledgeable staff" themes are the practical version of Arta's broader, repair-plus-water-control positioning. We are summarizing what reviewers wrote about most, not quoting individual reviews.

The real difference: a focused crack specialist vs a broader foundation contractor

This is the comparison that matters for this pair, and it is a verifiable difference in scope rather than a swipe at either. Crack-X is the focused specialist. For more than 30 years it has worked foundation crack injection, epoxy and urethane, plus bulkhead waterproofing, and that is most of what it does (crackx.com). When the problem is one cracked poured-concrete wall weeping water, or a bulkhead that leaks every spring, that depth on a narrow craft is the argument for Crack-X.

Arta Foundation Repair is the broader contractor. It handles foundation repair, crack repair, concrete leveling, water control, and sump pumps, and it serves most of New Hampshire plus parts of Vermont and Maine (artafoundationrepairs.com). When the job is more than a single crack, a sunken slab to lift, a wet basement that needs a sump and drainage, a foundation issue tangled up with grading and water management, Arta's scope is the better fit, and its review themes of reasonable pricing and knowledgeable staff back that up.

One boundary applies to both, and it is the most important sentence on this page for some homeowners. Neither Crack-X nor Arta is a heavy structural-piering provider. If your problem is a settling foundation, a sinking corner, or a bowing wall that needs helical piers or wall anchors, that is a different category of work, and it points to a firm that installs piers: Erickson Foundation Solutions (a Foundation Supportworks dealer), Groundworks, or 603 Basement Solutions (which installs helical and push piers in-house). Get one of those out for a structural-movement diagnosis rather than asking a crack-injection or concrete shop to stretch into piering.

Warranty

Warranty is the clearest documented edge for Crack-X. It publishes a 10-year transferable warranty on most wall cracks and positions its method as less expensive than similar approaches (crackx.com). A transferable warranty matters when you sell the house, and a published term you can read before signing is better than one you have to ask about. The warranty even surfaces in Crack-X's reviews, with five separate mentions (Crack-X on Google).

Arta does not state a warranty on its website (artafoundationrepairs.com), so ask for the term and the coverage in writing at the quote. That is not a mark against the work, but it is a gap in published information, and a written warranty is only as good as what the contract actually says. With either company, get the covered scope, the duration, and the transfer terms on paper.

On the BBB, Crack-X holds an A+ rating but is not accredited on its Manchester profile. Arta we have not assessed here, so we make no BBB claim for it.

Pricing

Like nearly every foundation specialist, neither company publishes fixed prices online, and both quote after a free inspection, because the number depends on the crack, the wall, the slab, or the water source in front of them. We will not invent a figure. What the public record gives us is one honest signal each.

For Crack-X, the company itself positions its crack-injection method as less expensive than similar methods (crackx.com). That is the company's own framing, not an independent price, so treat it as a claim to verify against a written quote rather than a guaranteed saving.

For Arta, the pricing signal comes from customers: "reasonable pricing" shows up 9 times in its review themes, one of its most-mentioned topics (Arta on Google). That is reviewers reporting their own experience, which is useful, but it is sentiment from about 50 reviews, not a rate card. When two quotes land on your table, compare them on the same scope, not the bottom-line number, and ask each company to spell out exactly what the price covers and what would change it.

How they net out

Our pick

It is close, and the right answer depends on the job, so we will give two picks tied to scope rather than declaring one company better across the board.

For a single foundation crack or a leaking bulkhead, our pick is Crack-X. The case is straightforward: more than 30 years on exactly that narrow craft, a published 10-year transferable warranty on most wall cracks, a clean review floor with no one-star ratings on the listing we recorded, and warranty plus responsiveness showing up in the reviews themselves. To be clear about what that pick is not: it is not a verdict that Crack-X is the higher-rated company, because the five-star shares are tied, and it is not the pick for a job wider than crack and bulkhead work.

For foundation repair combined with concrete leveling or water control, our pick is Arta Foundation Repair. Its scope covers leveling, sump pumps, and water management that a focused crack shop does not, its service area is wider, and its review themes of reasonable pricing and knowledgeable staff line up with that broader work. On the headline number the two are effectively tied: Arta and Crack-X sit within a tenth of a point of each other on five-star share, across similar review bases, so neither one leads on customer satisfaction.

Both are strong specialists for crack, leak, concrete, and water work. Neither is a structural-piering provider, so a settling or bowing wall points instead to a firm that installs piers, such as Erickson Foundation Solutions, Groundworks, or 603 Basement Solutions. The honest move is to match the company to the job, get a free inspection and a written quote, and read the warranty terms before you sign.
