Small Household Repairs: DIY, Tradesperson or Landlord — Who Does What?

The faucet drips, the door squeaks, the blind is stuck — every household has these small nuisances that add up week after week. The question of whether to grab the screwdriver yourself or call a tradesperson often decides between lost hours of free time and surprise bills. This article shows you which repairs you can safely tackle yourself, where the professional is unavoidable, and how to calculate tradesperson costs properly — including the often overlooked tax benefits and tenant rights.

The Small Repairs Every Household Faces

Almost every home knows the same classics: dripping faucets, wobbly door handles, burnt-out light fixtures, stuck window handles, leaky silicone joints in the bathroom. These everyday repairs quickly cost €80 to €150 per case when professionally handled — over ten years, a substantial four-figure sum.

Anyone handy with tools saves 30 to 50 percent through DIY. Tempting, but not universally advisable. Two hurdles are often underestimated: time and risk. The internet has taught us that anyone can do anything if they just watch a YouTube tutorial. Reality looks different.

A sober fact check: up to 300,000 DIY accidents happen in Germany each year. Particularly dangerous are electrical, gas and water works, where laypeople consistently underestimate what can go wrong. Add to that the follow-up costs when the self-made repair fails two weeks later and a professional charges double to fix the mistake.

DIY or Professional: The Right Dividing Line

Rule of thumb: anything involving electricity (above 25 volts), gas, or drinking water systems belongs in the hands of a qualified tradesperson. Not just for safety reasons, but legally too — many insurance policies do not cover damage from amateur work on these installations. Everything else you can basically do yourself, given a minimum of tools and time.

A sensible orientation:

Clearly DIY-friendly:

• Dripping faucets (replace washer or cartridge)
• Renewing silicone joints (bath, kitchen)
• Adjusting doors, oiling hinges, tightening door handles
• Replacing window handles
• Hanging lamps (where an existing ceiling outlet is installed)
• Repairing blinds and shutters
• Painting and wallpapering walls
• Assembling and fixing furniture
• Hanging pictures

Better to call a professional:

• Electrical installations from the fuse box onwards (sockets, switches, lamp connections without existing outlet)
• Heating work, thermostats, underfloor heating
• Sanitary installations behind the wall
• Gas boilers and gas connections
• Roof work and facade repairs
• Replacing roller shutter motors
• Drywall in load-bearing areas

The line is not arbitrary. For electrical work, 50 percent of former DIYers now prefer to hire professionals, for plumbing even 64 percent. The reason: one real water damage incident, and the DIY mentality evaporates fast.

Note for tenants: Even if you wanted to repair yourself — for many works on rental installations, the landlord is responsible. More on that below.

What Tradespeople Really Cost

Hourly rates have risen significantly in recent years. Current industry data for 2026 paints the following picture:

Trade	Hourly rate (net)	Typical small repairs
Painter	€45-65	Wall painting, wallpapering
Carpenter	€55-75	Doors, furniture, built-ins
Electrician	€55-85	Socket, switch, lamp
Plumber (HVAC)	€60-90	Heating, bath, kitchen
Plumber (water)	€75-130	Water line, drain
Roofer	€65-95	Roof, gutter, insulation

On top is a travel flat fee of €15 to €50 per job, sometimes also arrival and return travel time as regular work time. In big cities like Munich, Frankfurt or Hamburg, prices are 15 to 25 percent above the national average. If the tradesperson brings material, a markup of 10 to 30 percent on the purchase price applies — this is standard and covers logistics and warranty.

A typical small repair — faucet change with your own material — takes about 45 minutes with an installer. Plus arrival plus billing, you end up at one hour and thus €90 to €130. Even if you only have the washer replaced, you pay similar, because the minimum billing time is usually one hour.

Rental Apartment: Who Pays Which Small Repair?

If you live in a rental, the payment question is legally regulated. According to the minor repairs clause under standard German case law, the tenant must pay for certain very small repairs — but only under strict conditions:

1. The repair concerns parts exposed to the tenant's direct use — faucets, door handles, window locks, light switches, blind cords
2. The single repair does not exceed a certain limit — case law accepts €75 to €110, typically €100
3. The annual sum of all small repairs is capped — typical are 6 to 8 percent of annual cold rent. At €500 cold rent per month (€6,000 per year), that's €360 to €480 per year
4. The landlord must commission the tradesperson — clauses forcing you to commission yourself are invalid

Practically that means: if the faucet drips, you report this in writing to the landlord. They commission the tradesperson, pay the bill, then ask you to cover the costs — but only if all four conditions are met and the clause in your rental contract is valid. For larger damages (broken boiler, clogged drain, burst water pipe), the landlord always pays.

Important: Per Stiftung Warentest, many small-repair clauses in older rental contracts are invalid. In doubt, a legal review pays off — often you as tenant don't have to pay anything, even if the contract says otherwise.

The Five Most Common DIY Repairs Step by Step

These five classics can be done by almost anyone with some patience. You need a basic toolbox (screwdrivers, pliers, water-pump pliers, Allen key set) and a quiet hour.

1. Dripping faucet (15 min): Close the main water valve under the sink. Unscrew handle, remove old washer or cartridge, insert new one, screw handle back on. A washer set costs €5 to €15, a new cartridge €15 to €50
2. Renew silicone joint (45 min): Cut out old joint with cutter knife, clean surfaces with silicone remover, apply new joint with silicone gun, smooth with moistened finger or joint tool. Silicone tube €5 to €12
3. Tighten or replace door handle (10 min): Loosen screw on handle shaft with Allen key, pull off handle, insert new spring or handle set, tighten back
4. Adjust window hinge (20 min): Window crooked? On the hinges there is usually an Allen adjustment point you can use to re-level the window
5. Clear blocked drain (30 min): Plunger for light clogs, drain cleaner for medium, unscrew siphon and empty for stubborn cases. Never mix two chemical cleaners — risk of toxic gas

The timings assume all tools and materials are at hand. If you need to shop first, add 45 minutes plus €5 to €20 in travel and opportunity costs.

When You Absolutely Should Call a Professional

There are situations where any minute of self-attempt is one minute too many. The clear professional cases:

• Power outage with unclear cause — checking the fuse box is OK, but everything beyond is electrician work. Opening a live outlet is life-threatening
• Gas smell — window open immediately, gas valve closed, no electrical switches, call gas emergency (varies by region, in doubt 112)
• Water damage with wall moisture — the longer you hesitate, the higher follow-up costs. Mould grows within 48 hours
• Heating failure in winter — in sub-zero temperatures, water lines can freeze, pipe bursts are then only a matter of time
• Leaking roof — every day of rain costs you more than the roofer would charge

In emergencies, a good insurance (home content, liability, building) has a fixed partner tradesperson who comes within hours. Many people forget they already pay for this service — check your policies before the panic call.

On Helpful Folks you can find reliable tradespeople in your region with reviews from other customers — that makes emergency search much more efficient than calling three different craft businesses.

Cost Estimate or Fixed Price: What Legally Applies

For larger jobs, the type of price agreement decides whether you end up paying more than planned:

• Fixed price: Binding. The tradesperson may not charge more than agreed, even if the work turns out more complex than expected. Good for plannable jobs with clearly estimable scope
• Cost estimate: Non-binding approximation. In practice, case law accepts an overrun of up to 20 percent — above 20 percent, the tradesperson must inform you before continuing work
• Hourly billing by effort: Flexible but unpredictable. Good for very small jobs, bad for larger projects

The proven tactic for repairs over €200: obtain at least two written quotes and insist on a fixed price. A reputable tradesperson usually creates the estimate free of charge (unless an extensive inspection with measurements is needed). Have that confirmed in advance — a binding price with service list protects you from surprises.

20 Percent Tax Credit: How the Tax Office Relieves You

Repairs in your own household count as tradesperson services under § 35a EStG and are tax-favoured. You can deduct 20 percent of the labour costs directly from your tax liability, up to a maximum of €1,200 per year. The calculation basis is €6,000 in labour costs.

Three conditions for the tax benefit:

1. The invoice separately shows labour costs — materials don't count, only labour, machine and travel costs. Ask the tradesperson specifically for separate itemisation
2. Payment by bank transfer — cash is excluded by the tax office, even with receipt
3. Work in your own household — both owners and tenants can use this, for house, apartment or secondary residence

This really pays off: a small repair of €150 (of which €100 is labour) brings you €20 back. For a larger repair of €1,500 in labour, you land at €300 refund — not a negligible item at year end.

How to Find a Reputable Tradesperson

Finding tradespeople is a sore point for many. Recommendations from friends or neighbours are gold, but not always available. With new providers, watch for:

• Master certificate or trade chamber listing — mandatory for many trades, offers warranty and liability
• Written quote with service list — verbal agreements often end in dispute
• Transparent communication on arrival costs, materials and extras before order
• Reviews on reputable platforms like Helpful Folks — isolated negative reviews are normal, patterns are warning signs
• Liability insurance — ask explicitly for larger jobs
• Offer invoice by bank transfer — cash-only talk is suspicious

One last tip: don't compare pure hourly rates. A tradesperson at €85/hour who completes work in one hour is cheaper than one at €65/hour who needs two. Reputable tradespeople provide a realistic time estimate in the quote — and stick to it.

Conclusion

Small household repairs are an eternal topic — and with some planning, no reason to panic. Those who know the basic rules — electricity and water to the pro, simple mechanics yourself — save time and nerves. For tradesperson services, the typical hourly rate in 2026 is €45 to €130 depending on trade, with a 20 percent tax deduction at year end. Tenants should know they don't have to pay for every repair, and their landlord must commission the tradesperson.
