Tenant Mistakes: Insulation & Windows in Sweden

As a tenant in Sweden, it is common to wonder who is responsible for insulation, windows and other repairs in the apartment. This guide explains common mistakes tenants make — for example waiting too long to report problems, doing major window work without permission or ignoring moisture and sealing issues that later become costly. You will get clear advice on what typically falls on the landlord versus the tenant, how to document damage and how to step-by-step demand repairs if problems persist. The guide also shows when it is appropriate to contact the Rent Tribunal and where to find official rules. Preventive measures and proper documentation save both time and money.

Common tenant oversights

Several common mistakes lead to unnecessary costs or conflicts. It is especially important to address drafts, moisture and damaged window frames early, because these issues often worsen over time. In many cases the landlord is responsible for fixing defects that affect the condition of the dwelling according to applicable rules and practice^[1].

• Waiting too long to report drafts or damaged sealing strips.
• Attempting major window repairs without the landlord's written approval.
• Ignoring moisture or mold that affects insulation and indoor climate.
• Misunderstanding who is responsible for insulation in exterior walls or window connections.
• Lacking documentation of actions, notifications and responses from the landlord.

Immediate actions you can take

Start by reporting the defect to the landlord in writing and describe what you have observed, when it was discovered and attach photos. Also state which remedy you want and give the landlord a reasonable time to fix it. If the landlord does not respond or fix it in a reasonable time, you can contact the Rent Tribunal for mediation or decision^[2].

Responsibility for windows and insulation

Generally, the landlord is responsible for ensuring the dwelling meets acceptable standards and that insulation and windows do not cause inconvenience to the tenant. Minor routine maintenance can sometimes be the tenant's responsibility if agreed in the lease, but the landlord often bears the cost for measures that affect the building's construction or safety. In disputes, the Rent Tribunal can clarify and the Enforcement Authority handles execution if required^[3].

Common solutions and cost issues

In practice, the solution may be that the landlord pays for sealing, replacement of seals or repair of frames. For tenant-led repairs, always have written approval to avoid liability. If the damage is due to tenant negligence the landlord may claim compensation, but the landlord often has the burden of proof in disputes.

FAQ

Who pays for window replacement?

If the window is worn by normal aging it is more common that the landlord pays for replacement; if the damage was caused by the tenant they may be liable for compensation.

What do I do if there is a draft and the landlord does not act?

Report in writing, document with photos and give the landlord a reasonable deadline. If nothing happens, you can turn to the Rent Tribunal for a decision.

Can I replace sealing strips myself?

Minor adjustments may be allowed, but do not replace or alter the window construction without written landlord approval.

How-To

1. Contact the landlord in writing and explain the problem clearly.
2. Document the damage with dates, photos and any receipts.
3. Give the landlord a reasonable deadline for repair and save all correspondence.
4. If nothing happens, apply for a review at the Rent Tribunal or seek advice.
5. If you win the review and the landlord does not comply, enforcement can be carried out via the Enforcement Authority.
