Construction defects and the client's remedies: step by step follow a set order: notify the contractor promptly, document the defect, give an opportunity to remedy, then move to withholding payment, price reduction, or damages if the defect is not fixed. Skipping a step, or missing a deadline fixed in the contract, can extinguish the remedy before it is ever used.
Who this concerns
This is written for the party commissioning works, not the contractor: a developer, a property owner, or an operator of infrastructure that has taken over, or is about to take over, a completed or partly completed construction project and has found something that does not match what was agreed. It applies whether the defect surfaces at final inspection, during a warranty inspection some time later, or mid-project when partial handovers are involved.
The procedure described here sits inside the wider real estate and infrastructure practice, because a defect claim rarely travels alone. It interacts with the price mechanism in the contract, with any security the contractor has provided, and, if the project involves a lender or a buyer relying on the asset, with representations made to that third party. None of that changes the basic sequence: what changes is how much is at stake in getting the sequence right.
The commercial audience for this material is the client side of a construction contract governed by Swedish law, whether the contract uses a bespoke document or standard construction conditions of the kind commonly used on the Swedish market. The steps below apply regardless of which drafting convention was used, because the underlying logic of notice, opportunity to remedy, and escalation is the same.
What the law says
Under Swedish law as it currently stands, a contractor who delivers work that does not conform to what was agreed is liable for that non-conformity, and the client's remedies exist to correct the gap between what was promised and what was delivered. The starting point is always the contract itself: what was specified, what standard the finished work was meant to meet, and what process the parties agreed for raising and resolving defects.
Where the contract is silent or where general rules fill a gap, the logic that applies is consistent: the contractor is normally the party best placed to fix its own defect, so the client's right to demand a remedy stands ahead of remedies that bypass the contractor entirely, such as engaging someone else and charging the cost back. Withholding payment, reducing the price, and claiming damages sit alongside that primary right, available in different combinations depending on whether the contractor has had, and used, a genuine opportunity to put things right.
No specific time limit, threshold, or monetary figure is stated here without a contractual or regulatory source in front of us, because the exact framework depends on which contract conditions apply and on any adjustments the parties made to them. What follows describes the mechanism, not the numbers a particular contract will contain.
How it works in practice
Step 1: Record the defect before anything else
The first move is not a phone call to the contractor, it is a written record: what the defect is, where it is, when it was found, and by whom. Photographs, an inspection report, or a note in the project diary all serve this purpose. This record becomes the reference point for every later step, including any dispute about whether the defect existed at all, when it appeared, and whether it is genuine wear rather than non-conformity.
Step 2: Notify the contractor without delay
Once the defect is recorded, it has to be communicated to the contractor in a form that can be proved later: a letter or an email, not a verbal remark on site. The notice should identify the defect with enough precision that the contractor can act on it, and should be sent as soon as reasonably possible after discovery. Sitting on a known defect while continuing to use the works without saying anything is one of the more common ways a client weakens its own position.
Step 3: Give the contractor a real chance to remedy
Before turning to other remedies, the client generally has to give the contractor an opportunity to fix the defect itself. This is not a formality: the contractor is entitled to a reasonable window and reasonable access to the site to carry out the remedy. A client who brings in another firm to fix the problem before the original contractor has had that chance risks losing the right to charge the cost back, because the contractor's primary right to remedy has been bypassed.
Step 4: Decide whether withholding payment is justified
If payments are still due under the contract, withholding an amount that reflects the value of the defect is usually available as a self-help remedy while the matter is unresolved. The amount withheld has to bear a reasonable relationship to the cost or impact of the defect: withholding a disproportionate sum can itself become a breach on the client's side, so this step needs a documented basis, not a round number picked to apply pressure.
Step 5: Price reduction when remedy is not possible or refused
Where the contractor has failed to remedy within a reasonable time, refuses to remedy, or where remedy is not practically possible, the client can typically move to a price reduction reflecting the diminished value of the work. This remedy replaces, rather than adds to, the cost of the defect: it is not compatible with also charging the contractor for a third-party fix of the same item.
Step 6: Claims for damages beyond the price
Damages become relevant where the defect has caused loss beyond the value gap the price reduction already covers: consequential costs, delay costs, or loss flowing from the defect while it existed. This is usually the remedy that requires the most evidence, because the client has to show the loss, the causal link to the specific defect, and that the loss was not something the client could reasonably have avoided.
Step 7: Escalation, and the forum that will hear it
If the contractor disputes liability, disputes the scope of the defect, or simply does not respond, the matter moves toward formal dispute resolution: the general courts, unless the contract routes disputes to arbitration, in which case the arbitration clause governs both the forum and, often, the procedural timetable. Which route applies is set entirely by the contract, so this is one of the first things to check once informal steps have stalled.
Documents the case needs from day one
- The construction contract and any amendments, including the conditions governing defects and remedies specifically.
- The written notice of the defect and proof of when it was sent and received.
- Inspection reports, photographs, and any expert assessment of the cause and extent of the defect.
- Correspondence in which the contractor is given the opportunity to remedy, and any response.
- Records of costs incurred because of the defect, kept separately from ordinary project costs.
- Payment records showing what has been paid, what is outstanding, and what has been withheld.
What to check before each step
- Whether the contract conditions impose a specific form or channel for defect notices.
- Whether an inspection or warranty period under the contract has already started, and where the case sits inside it.
- Whether the defect was visible and unremarked at handover, which can affect which remedies remain open.
- Whether withholding payment risks triggering a separate breach claim from the contractor over unrelated invoices.
- Whether the contractor has provided a guarantee or security that a claim should be directed against in parallel.
Common questions on this procedure
How quickly must a defect be reported to preserve the remedy?
There is no single figure that applies regardless of contract: most Swedish construction conditions set their own notice periods, and general principles otherwise expect notice within a reasonable time after discovery. The safer approach is to notify as soon as the defect is recorded, rather than testing how long a reasonable period might be read to extend.
Can the client withhold the entire remaining payment because of one defect?
Not automatically. The amount withheld should correspond to the cost or impact of the defect, not to the full outstanding balance. Withholding materially more than that can expose the client to a counter-claim from the contractor for late or incomplete payment on unrelated work.
What happens if the contractor disputes that a defect exists?
The dispute moves to whichever forum the contract designates, generally the courts or an arbitral tribunal, and the client's documentation from the notice stage becomes the core of its case. Without a written record from the outset, disputing a contractor's denial becomes considerably harder.
The numbers
No specific deadline, monetary threshold, or limitation period is stated here as a general rule, because each of those depends on the contract conditions actually in force, and inventing a figure that does not come from the contract or from the applicable rules would be worse than leaving the gap. What can be said with confidence is structural: a construction contract will normally set its own notice period for defects, its own inspection or warranty framework, and its own rules on what happens if that period passes without notice.
Whatever the contract says on these points sits above any general default, so the practical task is to locate those clauses first, before assuming a period the client thinks is standard. Missing a contractual deadline is one of the most common ways a client's remedy is lost before the substantive dispute is even reached, and it is avoidable purely through checking the document rather than assuming its content.
Where it usually goes wrong
The sequence above assumes a defect that was unknown at handover, a solvent contractor, and a contract governed entirely by Swedish law between two parties inside Sweden. Several of those assumptions fail regularly.
A defect the client knew about, or should reasonably have discovered, at the point of handover and accepted without reservation is treated differently: signing off on the works without noting a known issue can be read as accepting that condition, which narrows the remedies available later. This is why the inspection at handover matters as much as anything that follows it.
Where the contractor's group has restructured, been sold, or undergone a change of control during the project, the client's remedy can end up pointed at an entity with fewer assets than the one that signed the contract, and separately, a change of control on the contractor's side can itself raise screening questions under merger control and investment screening rules affecting board exposure if the sector or the parties are within scope. Neither of these follows automatically from a defect claim, but both are worth checking early rather than discovering them after a claim is already filed.
Where the contractor is part of a foreign group, or where the contract routes disputes to arbitration seated outside Sweden, the practical value of a favourable outcome depends on being able to enforce it. A judgment or award against an entity with no assets in Sweden is only as useful as the enforcement of a foreign arbitral award in the jurisdiction where the assets actually sit, and that question should be part of the client's thinking before, not after, choosing which remedy to pursue and how hard to pursue it.
Finally, registering a claim or a charge connected to the defect against the property itself, where that is relevant to the dispute, interacts with changes to title and encumbrances entries in the land register, and that entry needs to be checked against the current register state rather than against what the client assumes it says.
What to do next
The steps above take a client through notice, remedy, and the choice between withholding, price reduction, and damages. What they do not do is tell a specific client, on a specific contract, which remedy fits the facts, whether a notice already sent was adequate, or whether a withheld amount is defensible if challenged. That assessment requires the actual contract, the actual notice correspondence, and the actual cost evidence in front of a lawyer, not a general description of the mechanism.
Lodline's construction defects remedies service is built around exactly that review: taking the contract and the correspondence already produced and setting out, in writing, which remedies are available, in what order, and what still needs to be done to preserve them. Where the dispute has already moved toward arbitration, the boundaries of challenging an arbitral award are worth understanding before that stage is reached rather than after.
