[¶ 1] David Paffhausen appeals from an order entered in the Knox County Probate Court (Emery, J.) rejecting his quantum me-ruit claim against the estate of Elizabeth Balano but allowing recovery for unjust enrichment. Because we conclude that David was entitled to recover pursuant to the theory of quantum meruit, we vacate the judgment.
[¶ 2] In March 1990, David, who is a carpenter and an artist, asked Elizabeth Balano for permission to renovate a building owned by her. David had hoped to convert the building into a fine art print shop. The evidence shows that Elizabeth approved David’s request, with the understanding that he would pay her $60.00 per month after he “got the business up and running.” Over the course of David’s extensive renovations, 1 Elizabeth at various times signed notes to various town authorities approving his work and allowing him to procure permits. She also gave him a signed note on December 11, 1991 stating: “To Whom it may Concern— David can use my house as long as he needs it.” 2
[¶3] The building was revamped sufficiently to allow David to host two art shows in 1994 and 1995. After Elizabeth’s death in October of 1995, her personal representatives offered David one year of free rent, after which his rent would be $60 per month, but for no definite term. David rejected the offer, presumably because beyond one year he would be a tenant at will, subject to eviction. Throughout the period of David’s renovation of the property, Elizabeth or her estate paid all real estate taxes and insurance premiums, and David has paid no rent.
[¶ 4] In 1996 David filed a claim against Elizabeth’s estate. The estate disallowed the claim. Pursuant to 18-A M.R.S.A. § 3-806, David filed a petition to resolve a disputed claim in the Probate Court. After a hearing, the court rejected David’s theory of quantum meruit, but did allow David to recover $12,-300 as unjust enrichment based on what the court found to be the value of the improvements to the budding.
[¶5] David contends the court erred in concluding that he failed to prove the elements of
quantum meruit.
David argues that he and Elizabeth had an understanding that for the renovations he made to the budding he reasonably expected to receive, and Elizabeth promised to give, “the use of the budding at no or nominal rent” for as long as he needed it, and that this understanding entitles him to recover from the estate in
quantum meruit.
On appeal, we defer to the trial court on its findings of fact, but review de novo the application of the law
*271
to those facts.
Estate of Plummer,
[¶ 6] We have recently explained the difference between
quantum meruit
and unjust enrichment.
Quantum meruit,
also sometimes labelled “contract implied in fact,” involves recovery for services or materials provided under an implied contract.
See Aladdin Elec. Assoc. v. Old Orchard Beach,
[¶7] Damages in unjust enrichment are measured by the value of what was inequitably retained.
Id.
In
quantum meruit,
by contrast, the damages are not measured by the benefit realized and retained by the defendant, but rather are based on the value of the services provided by the plaintiff.
See Siciliani v. Connolly,
[¶ 8] A valid claim in
quantum meruit
requires: “that (1) services were rendered to the defendant by the plaintiff; (2) with the knowledge and consent of the defendant; and (3) under circumstances that make it reasonable for the plaintiff to expect payment.”
Bowden v. Grindle,
*272
[¶ 9] While the formalities of an express contract are not a prerequisite to recovery in
quantum meruit,
there must be a reasonable expectation on the part of the claimant to receive compensation for his services and a “concurrent intention” of the other party to compensate him.
Estate of White,
[¶ 10] Although the decision of the Probate Court reflects thoughtful attention to the details of the case, the court nevertheless erred in its application of the law of
quantum meruit
to its factual findings and in its conclusion that the evidence does not support a recovery in
quantum meruit.

The court did find that extensive services were rendered by David to renovate the building, and that Elizabeth “approved of his desire to transform her building into a print shop/art gallery.” The court, however, erroneously concluded that David failed to show a reasonable expectation of payment. The court determined that there was no “contemporaneous understanding between the parties,” and concluded there was no evidence that Elizabeth intended to reimburse David for his expenses. The court would not allow David recovery in
quantum meruit
unless he proved
Elizabeth’s intention
to compensate him fully for all of his labor and expenses to convert the building either through cash reimbursement or use of the building for as long as he wished for a nominal rent. All that the law of
quantum meruit
requires David to prove, however, is that he had a reasonable expectation that his work was not gratuitous and that Elizabeth
by her words or conduct
justified this expectation.

Colvin v. Barrett,
*273
[¶ 11] Elizabeth’s note that “David can use my house as long as he needs it” falls short of an express contract. Yet the court’s findings of Elizabeth’s “full consent and support” for David’s renovations, and that Elizabeth told David that “when he had it functioning as a print shop he could pay her $60.00 a month rent,” and the other evidence, including Elizabeth’s written statement that David could “use my house as long as he needs it,” compel a finding that “services were rendered under circumstances consistent with contract relations.”
Danforth v. Ruotolo,
[¶ 12] On remand, the court must determine the
reasonable
value of David’s labor and the materials that were used to renovate and improve the building,
William Mushero, Inc. v. Hull,
The entry is:
Judgment vacated. Remanded to Probate Court for further proceedings consistent with the opinion herein.
Notes
. The Probate Court found:
Petitioner did improve the properly; he cleaned it up and hauled many loads of trash to the dump; he shored up the building; he built up forms, he rebuilt the foundation; he removed contaminated soil from around the building; he had the chimney rebuilt; he installed a wastewater system....
These findings were well-supported by the record.
. David testified that in April of 1993, he again approached Elizabeth for more formal assurances as to his investment in the building to which she replied: "Don’t worry, the building is yours.” Her close friend, Jane Scarpino, testified that Elizabeth had said to her that "this young man was going to ... take the place” and renovate it.
. We have made an effort to overcome considerable confusion between unjust enrichment and
quantum meruit. See A.F.A.B., Inc. v. Old Orchard Beach,
Further confusion has resulted from our use of the term "quasi-contract” both to describe unjust enrichment.
Estate of White,
The association of quasi-contract and
quantum meruit,
as in
Bowden,
is not helpful, because it suggests that the
quantum meruit
recovery is not based upon contract principles, as we have said that it must be.
See Danforth,
The Restatement definition of quasi-contract is historically accurate, because it reflects the common law’s gradual acceptance of the essentially contractual writ of assumpsit even for debts arising out of non-contractual transactions where no express or tacit promise existed. See 1 Corbin on Contracts § 1.18(a) (rev. ed. 1993) ("The legal duties that were enforced by use of this fictitious promise have come to be described as quasi-contractual. In other words, a promise 'implied in law’ is a constructive promise, a term that denotes a set of facts that will be treated as if a promise is made.’’). The probable historical cause for associating quantum meruit with quasi-contract is that at common law quantum meruit recoveries for the reasonable value of services provided were deemed, "in the tortured logic of yesteryear,” to rest on a contract implied in law even when an express or implied contract existed. Id. at § 1.18(b).
Given the relative clarity that we have achieved in our distinction between
quantum me-ruit
and unjust enrichment,
see Aladdin,
. The court also erred in its factual finding that "the only evidence presented that [Elizabeth] intended to let [David] use the building as long as he wanted was his own testimony based on his recollection of one conversation ...” (emphasis added). David did produce a written statement from Elizabeth that was addressed to "whom it may concern” and stated "David can use my house as long as he needs it.”
. Thus, although Elizabeth’s actual expectation that David would be compensated obviates a need to address the issue of the reasonableness of her understanding, nevertheless an inquiry into the reasonableness of the recipient’s expectations could be relevant in some cases:
The law will not imply a promise to pay for services contrary to the intention of the parties, as where it is obvious that there was no intent on the part of either party that payment should be made, although, if the recipient of services should, as a reasonable person, have understood that the performer expected compensation, the actual belief of the recipient as to such matter is immaterial.
