Something urgent broke?

Call us. To work out straight away whether and when we can come, tell us three things.

Location
The town and address, or at least the district. Arrival time and travel cost depend on it.
Device
Laptop, desktop, router, printer — and the make or model if you know it.
The problem
What you see on the screen, how long it has been happening and what happened just before. In your own words.

What we fix on site

Computers, networks, email and data — at home, in the office and at work. If your problem is not listed, call and describe it.

  • SSD upgrades with data migration, RAM upgrades
  • Replacing failed components, dust cleaning
  • Printers, scanners, monitors and docking stations

Internet, Wi-Fi and networks

  • No internet, or Wi-Fi that keeps dropping
  • Router set-up and Wi-Fi coverage at home and in the office

  • When failures keep coming back — ongoing IT support

What we do not do

Better to say so now than to drive out for nothing.

Board-level electronics repair
We do not repair motherboards or electronic circuits. A failed component is replaced with a working one, and when a repair is not worth it, we say so plainly.
Laboratory data recovery
We do not open drives in laboratory conditions. We diagnose what happened, assess the chances and tell you the next step, so the situation does not get worse.
Getting around security
We do not crack passwords, bypass locks or access other people's accounts or devices. We help you regain access to your own accounts through the provider's official process.

You do not need to know what broke

Just tell us what you see: the computer will not turn on, the internet is down, email is not arriving. Leave part names, error codes and the diagnosis to us — that is what we come out for.

Bydgoszcz and the surrounding area — call-outs up to about 100 km

We cover Bydgoszcz and towns within about 100 km. For anything further, we confirm whether we can come and what it costs before we set off.

Places we come out to include

Your town is not on the list? Call — we will check the trip.

How much does it cost?

We do not quote blind, because every failure is different. The rules, however, are always the same.

The cost depends on the problem
Setting up email is not the same job as replacing a drive and moving the data. The scope is agreed after diagnosis.
Travel depends on distance
We give you the travel cost on the call, once we know the town.
You know the terms before work starts
Travel cost and how the work is priced are confirmed before we set off, and paid work starts only with your consent.

24/7 — what it means here

We take requests at any time, including nights, weekends and public holidays. Urgent call-outs outside normal hours are possible, but we do not promise them blind: whether and when we can come is confirmed on the call, depending on the location and current availability.

How it works

  1. You call

    At any time. If you cannot talk, leave a request in the form — we will call you back.

  2. You describe the problem and the location

    What is happening, on which device and where you are. We will ask about the rest.

  3. We confirm the call-out and the terms

    We tell you when we can be there and what the travel costs. The decision is yours.

  4. The technician arrives

    Diagnoses the problem on site, tells you what needs doing, and fixes it with your consent.

Who you are dealing with

Before you let someone into your home or office, you have every right to check who they are. That is why the company's details are set out here in full.

From the “Informatyk z dojazdem 24/7 Bydgoszcz” profile — the name our on-site service trades under on Google Maps.

I had a problem with my laptop in the middle of the night. Someone was with me within the hour and the laptop was fixed in minutes.
Julia Szychowska
The technician was very pleasant, very patient, and would not let go until the problem was solved (it took nearly two hours), with no fuss and no taking the easy way out by resetting everything, just looking for the actual fix.
Malena T.
Brilliant service. The desktop was repaired quickly and perfectly. I will certainly use them again.
Mikołaj Piotrowski
Great service and an expert approach. The repair went quickly and everything works faultlessly.

Questions about call-outs and on-site help

Yes. We come out to homes and flats, and to offices, shops and practices — in Bydgoszcz and up to about 100 km away. The computer, internet, Wi-Fi, email or printer is checked where the equipment is.

We take requests around the clock, seven days a week. Urgent call-outs outside normal hours are possible, but not guaranteed in advance: whether and when we can come is confirmed on the phone, depending on the location and current availability.

Yes. Places we come out to include Osielsko, Niemcz, Białe Błota, Solec Kujawski, Nakło nad Notecią, Szubin, Żnin, Inowrocław, Świecie, Toruń and Grudziądz, and within Bydgoszcz itself Fordon and every other district. If your town is not listed, call and we will check the trip.

Up to about 100 km from Bydgoszcz. For anything further, we first confirm whether we can come and what the travel will cost — only then do we book the visit.

The travel cost depends on the distance. We give it to you on the call once we know the town, and confirm it before we set off, so you know it before you book.

Yes. We come out to offices, shops, practices and service points, and invoice companies with VAT. If failures at work keep coming back, it is cheaper and calmer to move to ongoing IT support, where response times are written into the contract.

Arrival time is confirmed on the phone, depending on the location and current availability. We do not quote it in advance, because it depends on where you are and what is happening on our side at that moment — on the call we tell you plainly when we can realistically be there.

Many problems are solved there and then — the system, settings, the network, email, printers. When a part is needed or the repair takes longer, we agree the plan and the cost with you before going further.

We tell you the cause and the next step. With your consent we can take the device for further diagnosis, order a part, or advise a replacement when a repair is not worth it. If the data needs laboratory recovery, we tell you how to protect the drive and what kind of service to turn to.

Yes: upgrading to Windows 11, problems after updates, checking whether the computer meets the system requirements, clean installations, setting up a new computer and moving data from the old one.

Yes. We set up routers, improve Wi-Fi coverage, find out why the connection keeps dropping and connect network printers. If the problem is on the provider's side, we say so and tell you what to report to their helpline.

Yes: setting up Outlook on a computer and a phone, problems sending or syncing email, Microsoft 365, Teams and OneDrive accounts, moving a mailbox. We only work on accounts you are entitled to — we do not crack passwords or get around security.

Yes. We are an active VAT payer. Companies receive a VAT invoice in the company's name; private clients receive one on request.

We take requests at night, at weekends and on public holidays too. Whether we can come at that moment is confirmed on the call, and the terms — including the cost — are agreed before we set off.
