Expert report on poorly executed renovation in Mallorca

Expert report for poorly executed renovations in Mallorca: If a project ends up with dampness, leaks, cracks, faulty installations, substandard finishes, or materials different from those agreed upon, photos or WhatsApp messages aren't enough. To make a successful claim against the construction company, the contractor, the insurance company, or even in court, you need a technical report explaining what went wrong, why it happened, who might be responsible, and how much the repairs will cost.

At Optima Pericial, a team of expert witnesses operating in Mallorca and throughout the Balearic Islands, we prepare expert reports on defective renovations for homeowners, homeowners associations, companies, lawyers, and insurance companies. Our goal is to ensure you file claims based on solid, objective, and defensible technical evidence, not just intuition.

In short: if your renovation in Mallorca is poorly executed, the first step is to document the damage, keep contracts and invoices, avoid repairs before the expert inspection, and request an independent technical report. This report will be the basis for negotiation, filing a claim against the contractor, contacting the insurance company, or filing a lawsuit if no agreement is reached.

What constitutes a poorly executed renovation and when can a claim be made?

A poorly executed renovation is not simply a project that didn't turn out as expected. For a claim to be valid, there must be a technical, contractual, or regulatory breach: work that doesn't match the budget, substandard materials, workmanship errors, deficiencies in installations, subsequent damage, or failure to comply with applicable technical standards.

In Mallorca, these types of problems are common in home renovations, including those involving tourist apartments, commercial premises, homeowners' associations, villas, terraces, roofs, bathrooms, kitchens, and facades. The island's climate, with its humidity, salinity in coastal areas, and frequent heavy rainfall, means that poor waterproofing or faulty installation can cause significant damage in a short period of time.

Difference between aesthetic defect and claimable damage

Not all defects are equally serious. An uneven finish may be grounds for a claim if it violates the agreed terms or the rules of good workmanship, but it is not as serious as a leak that affects habitability or a crack linked to a structural problem.

The expert's job is precisely to differentiate between a simple aesthetic discrepancy and a genuine technical defect. This classification is key to assessing the severity of the damage, the applicable time limit, and the claim strategy.

Main warning signs after a reform

It is advisable to request an expert review when signs such as damp stains, mold, persistent odors, faulty sockets, tripped circuit breakers, new cracks, lifted tiles, doors that do not close, uneven floors, noises or vibrations, condensation or leaks after rain appear.

It is also advisable to take action if the contractor avoids handing over documentation, does not respond to notices, denies obvious defects, or proposes improvised repairs without explaining the real origin of the problem.

Why you need an expert report to claim for a defective renovation

Without an expert report, a claim often gets bogged down in a back-and-forth argument: the owner says the work is faulty, and the contractor responds that everything was done correctly. An expert report on poorly executed renovations breaks this cycle because it provides an independent technical assessment.

The report not only describes the damages. It also identifies the causes, links the defects to the execution of the work, quantifies the cost of the repairs, and determines what documentation supports the claim. It is the document that transforms a complaint into evidence.

What should a quality expert report contain?

A good expert report should include, at a minimum, the identification of the expert, the purpose of the assignment, the documentation analyzed, the inspection carried out, dated photographs, description of defects, analysis of causes, applicable technical regulations, economic valuation of repair, clear conclusions and documentary annexes.

When a report is to be used in legal proceedings, it must also be written in a way that is understandable to lawyers and judges. An overly generic report, lacking measurements, causality, or economic valuation, may lose probative value.

The importance of the cause of the damage

A renovation project can involve contractors, subcontractors, architects, surveyors, installers, material suppliers, and even the homeowners' association. Therefore, simply stating that damage exists is insufficient; it's necessary to explain the specific action that caused it.

A leak can be caused by poorly executed waterproofing, insufficient slope, an unsealed joint, a blocked downpipe, or a pre-existing defect unrelated to the renovation. Each cause determines the liability and the procedure for filing a claim.

Most frequent damages caused by poorly executed renovations in Mallorca

Defects in renovations can appear from day one or weeks or months after completion. Below, we detail the most common defects in Mallorca and explain why they require a technical assessment.

Leaks and dampness

Dampness is one of the most frequent problems encountered during home and business renovations. It usually appears due to waterproofing failures on terraces, roofs, facades, bathrooms, interior patios, or where materials meet. It can also be caused by poorly installed pipes or defects in slopes and drainage.

The expert report must identify the source of the dampness, determine whether it is due to seepage, rising damp, condensation, or a leak, and assess the necessary corrective measures. This distinction is crucial because each source requires a different solution.

Faulty electrical or plumbing installations

An electrical installation that is improperly sized or installed without complying with the Low Voltage Electrotechnical Regulations can pose real risks to occupants. In plumbing, incorrect connections, unsuitable materials, or poorly executed slopes can cause leaks, unpleasant odors, or hidden damage.

In these cases, the expert may require additional tests, measurements, document review and analysis of the installation actually carried out versus what was budgeted or projected.

Cracks, fissures and movement in walls or ceilings

Cracks are not always structural, but they should never be ignored. They can appear due to poor construction of partitions, lack of joints, incompatible materials, settling, vibrations, or inappropriate interventions on existing elements.

The expert report should assess whether the crack is superficial, a finishing defect, or a symptom of a more serious problem. If necessary, monitoring, measurements, or specific tests may be recommended.

Poorly installed flooring, tiling and wall coverings

Lifting tiles, open joints, hollow pieces, uneven surfaces, misaligned tiles, or cracked paving are common defects in renovations. Often, these are due to poor surface preparation, the use of unsuitable adhesives, a lack of expansion joints, or rushed installation.

These damages are usually very visible, but to claim correctly you have to quantify the cost of removing, preparing and re-executing the affected items.

Materials other than those agreed upon

A claim can also be made when the company uses lower quality materials, different brands, unauthorized finishes, or technical solutions different from those agreed in the budget or quality specifications.

In these cases, the expert compares what was contracted with what was actually installed and assesses the economic difference, the technical impact and the possible need for replacement.

Thermal or acoustic insulation defects

If the renovation promised to improve insulation and the result doesn't meet expectations, acoustic measurements, thermographic imaging, or technical inspections may be necessary. These types of reports are especially relevant for tourist accommodations, commercial premises, and homeowners' associations.

Legal framework for claiming a poorly executed reform

A claim for defective renovations can be pursued through various legal avenues. The choice depends on the type of work, the contract, the extent of the defects, and the parties involved.

Building Regulations Act: when can it be applied

Law 38/1999, on Building Regulations, governs the liability of the parties involved in the building process. For works within its scope, it establishes liability periods of 1 year for finishing defects, 3 years for defects affecting habitability, and 10 years for structural damage.

It is important to clarify that not every minor renovation automatically falls under the full scope of the Building Regulations Act (LOE). Some claims are better addressed through the contractual provisions of the Civil Code. Therefore, it is necessary to analyze the type of work, including whether there was a project plan, permit, project management, and formal acceptance.

Civil Code: breach of contract

When a project fails to meet the agreed-upon specifications, a claim for breach of contract can be filed. This is particularly useful for home renovations when there is a budget, contract, invoices, messages, or any other documentation that proves what was agreed upon and what was actually delivered.

The Civil Code allows claims for damages when a party fails to fulfill its obligations, and personal actions that do not have a special time limit generally prescribe after five years from when compliance can be demanded.

Technical Building Code and technical regulations

The Technical Building Code is an essential reference for assessing basic requirements for safety, habitability, health, protection against humidity, energy efficiency, and other building performance. Specific standards, such as the Low Voltage Electrotechnical Regulations (REBT) for electricity or sector-specific regulations, may also apply to building installations.

A solid expert report links the observed defect to the violated technical rule. This connection is what demonstrates that we are not dealing with a mere opinion, but with an objectively verifiable deficiency.

Time limits for claiming damages for a defective renovation

Time limits are one of the most critical issues. In claims for construction defects, it's best to act as soon as possible, because evidence deteriorates and because each legal avenue has its own time limits.

Under the Building Regulations Act (LOE), actions to claim liability for material damages arising from defects or flaws are subject to a two-year statute of limitations, without prejudice to any remaining contractual actions. A properly filed extrajudicial claim can interrupt the statute of limitations, but it must be correctly presented.

When does the deadline start counting?

In works subject to acceptance, the calculation of liability and warranty periods begins from the acceptance certificate or from tacit acceptance. The Spanish Building Regulations (LOE) stipulate that, unless expressly agreed otherwise, acceptance must occur within 30 days of the completion of the work, as evidenced in the final certificate and communicated in writing to the developer.

In small renovations where there is no acceptance certificate or final handover document, the delivery date can be proven through invoices, correspondence, photographs, messages, final payments, or the return of keys. This is another reason why it's advisable to keep all documentation.

Steps to claim for a poorly executed renovation in Mallorca

An effective claim must follow a specific order. Skipping steps or improvising can weaken the case, especially if the responsible company denies the defects or if an insurance company becomes involved.

Step 1: Keep all documentation

Gather budget, contract, invoices, proof of payment, plans, quality report, licenses, messages, emails, before and after photographs, videos and any communication with the contractor.

It is also advisable to note relevant dates: start of work, completion, appearance of the defect, first communications and responses received.

Step 2: Do not repair before the expert inspection

Unless there is an urgent risk to people or property, it is best not to make any repairs before the expert has inspected the property. Premature repairs can destroy evidence and make it difficult to prove the cause of the damage.

If the repair is unavoidable due to urgency, document everything with photographs, videos, estimates, invoices and, if possible, keep samples of affected materials.

Step 3: Request an independent expert report

The expert inspects the property, analyzes the defects, studies the documentation, and prepares a technical report. This document can be used in an amicable claim, in negotiations with an insurance company, in mediation, or in court.

At Optima Pericial we adapt the report to the client's objective: a preliminary report for negotiation is not the same as a complete opinion for a legal claim.

Step 4: Make a formal claim

With the report in hand, it's advisable to send a formal communication to the contractor or responsible party, preferably via certified mail with return receipt requested. This complaint should identify the defects, request repairs or compensation, and clearly state your position.

A reliable claim helps to prove that the responsible party was aware of the problem and can interrupt the statute of limitations, provided it is correctly formulated.

Step 5: Negotiate or resort to legal action

Many cases are resolved out of court when the report is sound. If there is no agreement, the expert opinion will serve as evidence in a lawsuit. In that scenario, the expert can ratify the report and answer questions from the judge, lawyers, and opposing party's experts.

What documentation does the expert need to assess the renovation

The more information the expert receives, the more accurate the report will be. Ideally, the following should be provided:

• Budget accepted and construction contract.
• Invoices and proof of payment.
• Specifications, plans or project, if available.
• Municipal license or prior notification, if required.
• Photographs of the house before, during and after the renovation.
• Messages, emails and registered letters sent to the contractor.
• Repair estimates received from other professionals.
• Previous reports, insurance reports or technician visits.

It's okay if you don't have all these documents. The expert can work with the available information, but the more complete the file, the stronger the claim will be.

Common mistakes when claiming for a poorly executed project

Many property owners lose ground in their claims not because they are wrong, but because they act too late or without technical evidence. These are the mistakes that should be avoided.

Relying solely on photographs

Photographs are helpful, but they don't replace an expert report. An image shows that a stain or a crack exists, but it doesn't explain the cause, who is responsible, or the cost of repair.

Waiting too long because the contractor promises to repair

It's common for the company to promise a visit, a repair, or a solution that never materializes. Meanwhile, the damage can worsen and legal deadlines can approach. Goodwill is no substitute for a formal complaint.

Accepting partial repairs without documenting them

A poorly planned repair can temporarily mask the problem, only for it to reappear months later. Before accepting a solution, it's wise to assess whether it addresses the root cause or merely masks the symptom.

Not quantifying the damage correctly

Claiming a specific amount without a technical basis allows the other party to easily dispute the figure. The expert report must itemize costs, measurements, and repair prices to make the claim defensible.

Claim against the contractor's insurer

If the contractor has liability insurance, it may be worthwhile to also file a claim with the insurer. In these cases, the expert report is especially important because the company usually appoints its own expert who will analyze the claim looking for exclusions, coverage limits, or lack of a causal link.

Optima Pericial 's experience in the insurance sector allows us to anticipate these types of objections. We know which points companies review, how to structure the causal analysis, and how to quantify the damage to avoid insufficient offers.

Expert witness and court-appointed expert: important differences

The expert witness is hired by the owner, lawyer, company, or affected community to prepare a report supporting their claim. They must act with technical objectivity, even though their task is to defend a specific position.

The court-appointed expert is designated by the court when the proceedings require an independent technical assessment. Their report usually carries significant weight, but a well-prepared report from one of the parties involved can guide the technical debate from the outset and help defend the affected party's position.

At Optima Pericial we prepare expert reports and also have experience in judicial ratification, a key aspect when the procedure goes to trial.
