Which group suits you
This page is useful if you are renovating a bathroom, have a dripping tap or a water heater that needs replacing, or need a plumber for a heating system, a drain or a building project.
| If you need | What to look at | Which group fits | What to check |
|---|---|---|---|
| A new bathroom, or pipes for a kitchen or laundry room | Bathrooms, wet rooms or laundry rooms mentioned in the card description | Bathroom, kitchen and laundry room | Who coordinates the carpenter, the mason and the electrician: the firm or you |
| A leak, a new toilet, a new tap or a new water heater | Service jobs, repairs or leaks mentioned in the description | Service and repairs at home | When the plumber can come, and what the call-out and travel cost |
| Help outside working hours | A 24-hour hotline in the description: one firm states it | Service and repairs at home | The price outside ordinary opening hours, before the plumber sets off |
| A heat pump, underfloor heating, a boiler or gas | Heat pumps, underfloor heating, boilers or gas mentioned in the description | Bathroom, kitchen and laundry room, or Heating systems, drains and larger projects | Whether the firm takes your particular system |
| A drain inspection, a new build or work in a commercial building | Drains, new builds or projects mentioned in the description | Heating systems, drains and larger projects | Whether the firm takes jobs for private customers: some work mostly on building projects |
Bathroom, service or installations: what the firms themselves say they do
- The groups follow what the firms state in the card description, not where in the city they are.
- Eight of the twelve firms are based south of the centre, among other places on Tempevegen, Osloveien and Elgeseter gate.
- The other four are east of the centre: on Skippergata, Wessels gate and Kong Inges gate.
- Several take jobs in the neighbouring municipalities: the descriptions mention Malvik, Melhus, Stjørdal and Indre Fosen.
A plumber comes to your home, so the address matters less than what the firm is used to doing. That is why this page is divided by type of job. The first group has firms whose descriptions highlight bathrooms, wet rooms, kitchens and laundry rooms. The second gathers firms for service and repairs: replacing a toilet, a tap or a water heater, and fixing leaks. The third has firms for heating systems, drains, new builds and commercial buildings.
The lines are not sharp. Two of the firms in the bathroom group also fit heat pumps and underfloor heating, one takes gas installations such as propane systems, gas fireplaces and gas boilers, and one states digging and high-pressure flushing of drain pipes. In the third group you find service on boilers and oil burners, checking and fitting of water meters, and drain inspections. One firm there works mainly for the project market, among other things with drain systems for student housing, so for a dripping tap the service group is a better fit.
Several of the firms belong to a plumbing chain or a trade network: it is mentioned in the card description. This page is a selection, not a complete list of plumbers in Trondheim. The category Construction & Installation Services holds close to two hundred cards, where plumbers are listed together with electricians and other tradespeople. More practical guides are collected under Services & practical.
Before you ask for a quote: what your enquiry should say
- Describe the job and attach photos: what is to be done, and what it looks like today.
- Give the address, the type of home and roughly how old the pipes are.
- Ask whether the price is fixed or by the hour, and what comes on top.
- If you are renovating a bathroom, ask who coordinates the other trades.
The cards do not show prices, so you have to ask for the quote yourself. The phone number is in every card. The more specific you are, the easier it is to compare the answers: write what is to be done, attach photos and give the address. For larger jobs, such as a new bathroom, it is usual for the plumber to come and look at the site (befaring) before the quote is written.
Ask what the price covers. One of the firms states ready-fitted products at a fixed price, but otherwise you need to clarify whether the quote is a fixed price or by the hour, whether materials, travel and removal of old equipment are included, and when the firm can start. Ask to have the quote in writing.
A bathroom takes more trades than the plumber. One of the firms in the bathroom group states that it takes the job as main contractor and coordinates the carpenter, mason, electrician and painter. With the others, ask whether you have to find and coordinate the tradespeople yourself.
When it is urgent: duty phone and opening hours
- Most of the firms open between 07:00 and 08:00 on weekdays and close between 15:00 and 17:00.
- None of the cards shows opening hours on Saturday or Sunday.
- One firm in the service group states a 24-hour duty phone.
- If water is running, close the main stopcock before you call.
The plumbing firms on this page keep ordinary working hours. According to the cards in the directory in October 2026, most open between 07:00 and 08:00 on weekdays and close between 15:00 and 17:00, and none shows opening hours on Saturday or Sunday. Two of the cards have no opening hours. If you want to speak to someone in the office, a weekday morning is the safest time.
Cover outside working hours is documented for one firm. It states a 24-hour duty phone both in the card and on its own website (read on 6 October 2026), and writes in the same place that it has separate prices for jobs outside ordinary opening hours. So ask about the price before the plumber sets off. How quickly someone can come is not stated anywhere, so ask for an estimate when you call.
With a leak, close the main stopcock first, so the damage does not grow while you wait. Say on the phone where the water is coming from, and whether you have managed to shut it off. Take photos of the damage before you tidy up: they are useful both for the plumber and for your insurance company.
Questions and answers
On this page, one firm in the group Service and repairs at home states a 24-hour duty phone (the card calls it a 24-hour hotline): it is in the card description and on the firm's website (read on 6 October 2026). The other cards show ordinary working hours on weekdays.
The cards do not say. Ask for a written quote, and ask about the hourly rate, the call-out and travel charge, and what the materials cost.
Usually not without an appointment: the cards show opening hours on weekdays, and none shows Saturday or Sunday. The firm with the duty phone itself writes that it has separate prices outside ordinary opening hours.
Look in the group Bathroom, kitchen and laundry room. One of the firms there states that it takes the bathroom as main contractor and coordinates the carpenter, mason, electrician and painter; ask the others how they handle it.
Several do. The card descriptions mention the city and its surroundings, and some name Malvik, Melhus, Stjørdal and Indre Fosen.
Two firms in the group Bathroom, kitchen and laundry room state heat pumps and underfloor heating, and one states gas: propane systems, gas fireplaces and gas boilers. Service on boilers and oil burners is listed by one firm in the third group.
Call first. The cards do not say whether the firm has a shop or a showroom: the address shows where the firm is based, and the work is done in your home.
