FAQ — all in one place

Office cleaning for businesses, housing cooperatives and commercial buildings across Oslo and Romerike. We also offer post-construction cleaning, facility management, communal-area cleaning, window cleaning and end-of-tenancy cleaning — but office cleaning is our core. Every contract is delivered with fixed teams and written documentation.

Oslo and the whole of Romerike — including Lillestrøm, Lørenskog, Rælingen, Jessheim, Skedsmokorset, Strømmen and Nittedal. Our HQ is in Skedsmokorset, which gives us short travel times to all these areas.

Because cleaning contracts vary a lot — office size, frequency, special areas (canteen, server room), access. We always run a free site survey first and give a fixed written price afterwards. No hourly surprises, no hidden costs.

A written quote within 24 hours of the site survey. The survey itself is typically booked within 48 hours of first contact. For urgent needs — call us directly and we'll see what's possible the same day.

Yes. We're listed in the Norwegian Labour Authority's (Arbeidstilsynet) Cleaning Services Register as "Approved with employees" (company number 937 087 764). That means you can legally buy cleaning services from us — a requirement under the Norwegian Working Environment Act for cleaning services.

Yes. We follow the legally-binding sector-wide pay agreement for the cleaning industry (minimum NOK 228.99/hour in 2026). That means you, as a buyer, aren't risking social-dumping allegations or compliance issues during internal audits.

We use EU Ecolabel-certified products as standard. We are not Nordic Swan (Svanemerket)-certified as a service — that's a larger certification process we are considering for the future. We're upfront about this: we don't claim certifications we don't hold.

Norwegian and English as standard. Many of our staff also speak Lithuanian, Polish and Russian — useful for international businesses in Oslo. We're in the process of translating the website into several languages.

Yes. We carry public-liability insurance covering any damage to client premises or equipment caused during a cleaning job. Documentation is provided at the start of every contract.

Contact us immediately. For office cleaning and housing cooperatives: we'll come back within 48 hours and put it right at no extra charge. For end-of-tenancy cleaning: a 72-hour guarantee — issues raised within the window get a free re-clean. We believe in putting it right, not arguing about it.

No lock-in beyond the notice period. Standard is one month on either side for office cleaning and communal-area cleaning. One-off jobs (end-of-tenancy, post-construction) are book-and-deliver with no ongoing contract.

Monthly invoice (office cleaning, communal-area cleaning, facility management) or per-job (end-of-tenancy, post-construction, one-off window cleaning). Payment terms 14 days net. We accept EHF (Norwegian electronic invoicing) for businesses.

Market rates for office cleaning in Oslo typically sit between NOK 35 and 75 per m² per month — depending on frequency, building type and any special areas (canteen, server room). A 200 m² office cleaned twice a week usually lands in the NOK 7,900–10,900/month range. We don't publish prices on the website because every contract is priced individually after a site survey — contact us for a firm written quote.

In practice, the two are synonyms in Norwegian industry terminology. Some suppliers use "kontorvask" (office washing) for intensive jobs (deep floor scrubs, spring cleans) and "kontorrenhold" (office cleaning) for routine daily or weekly work. We use "office cleaning" as our default term but handle both.

It depends on headcount and building type. Rough guide: 5–15 staff = 1–2 times a week. 15–50 staff = 2–3 times. 50+ staff or open-plan = daily. Kitchens and toilets should always be cleaned daily regardless of size. See the detailed table higher up the page.

"Allmenngjort tariff" is a Norwegian-specific mechanism: a collective pay agreement made legally binding across the entire sector by the Tariff Board (Tariffnemnda). Minimum wages and working conditions apply to every employer, not just those who've signed up to the agreement. In cleaning, this has been in force since 2011. The minimum hourly wage is NOK 228.99 (2026). We pay it — which means your business cannot be accused of supporting social dumping by using us.

Yes — and it's the norm. Most clients don't want cleaning during opening hours. We typically work 06:00–08:00 or 17:00–20:00 on weekdays, whatever fits you best. Key handling is agreed in writing.

An experienced cover cleaner from our in-house team steps in — never a random contractor from a pool. We message your point of contact the same day. We never leave a job unfinished without notice.

Standard is one month on either side. For larger contracts — or on request — we can agree three months. No lock-in beyond the notice period.

Yes. Rimon Renhold AS is listed in the Norwegian Labour Authority's (Arbeidstilsynet) Cleaning Services Register as "Approved with employees", company number 937 087 764. That means you can legally buy cleaning services from us — something the Norwegian Working Environment Act requires.

Yes. Our monthly report covers work completed, issues logged, HMS ID-card references and product certification numbers (EU Ecolabel). It can be filed directly into ISO 9001 / 14001 audit records and public-tender responses.

Yes. Your point of contact can reach us by phone or email at any time. We aim to reply within 2 hours during business hours, and always by the following morning at the latest. All issues are logged in the monthly report.

A builders' clean is about removing construction-related residue — dust in ventilation, adhesive, paint, sanding powder. It requires specific techniques (scraping without scratching, rubber-free cleaners that leave no residue) that aren't part of routine cleaning. If an ordinary cleaner attempts a builders' clean, you won't get a clean building.

Preferably before. Furniture and textiles attract construction dust — if we go in first, the result lasts. Where needed, we can do a combined builders' clean and move-in, but it's usually more expensive because we have to work around the contents.

Yes, and in the final phase it's common. We'll work around a painter or electrician when it makes sense — but it's a balancing act: too much overlap means double work. We'll map out the sequence during the site survey.

Yes. We produce a handover protocol with a room-by-room checklist, signed and dated. Banks and property sellers accept it as evidence the builders' clean has been completed.

You can pick individual services. The package is flexible — build it from what you actually need. Many clients start with communal-area cleaning only and add caretaker services later.

You get a dedicated coordinator who knows the building, with a direct number and Norwegian-speaking communication. No call centre, no ticket system where issues get lost.

Yes. We have written key-handling and alarm-code procedures that meet insurance requirements. This is agreed at the start of the contract.

That's fine — we take the call and log it. But we only carry out work approved by the board or owner, and we flag to the board before acting on resident requests that fall outside the contract.

We provide a written quote after the site survey, which your board can review in the usual way. The contract is a fixed monthly price with 1–3 months' notice. Many boards ask for a 3-year framework agreement — we're flexible.

Everything is included — mops, cloths, products, consumables. You pay one fixed monthly price with no surprises.

Yes, with one week's notice. We can move cleaning days at no extra cost if the board or residents have arranged something specific.

Your board's point of contact flags it to us — we'll put it right within 48 hours, and it's documented in the monthly report. Repeat complaints about the same thing are resolved by adjusting the routine or swapping the team.

The team signs a stamp card in the post-box area, or logs a QR code — whichever you prefer. The monthly report includes photos when there's an issue — not on every visit (that would become a GDPR headache), but whenever there's something to report.

Homes: twice a year is enough for most — spring, and late autumn before the dark months. Offices: quarterly, or monthly if you're on a busy street. Shops: monthly or more often, especially the entrance.

Clean rainwater doesn't streak — dirty water does. If a proper downpour leaves visible streaks within 48 hours of the clean, we'll come back at no charge. With correct technique, this is very rare.

Yes. We bring buckets and ladders and plan the route so we don't tread on your beds. Flag any special plants or concerns during the site survey.

Yes — they're often done as part of an office-cleaning contract. If we already have a weekly cleaning contract with you, we can add internal glass for a small top-up.

If your landlord, the new owner or a chartered surveyor raises specific written issues about the cleaning quality within 72 hours of handover, we'll come back and put it right at no charge. We only ask that the issues are specific (e.g. "grease on top of the fridge", not "not good enough") so we can act on them.

Yes. We provide a signed end-of-tenancy protocol with date, address and a room-by-room checklist. It's particularly useful for deposit disputes — the landlord has to respond to specific points, not general complaints.

We'll meet you for a site survey within 48 hours and usually carry out the clean within 5 days of booking. For urgent handovers — same week, sometimes same day — call us directly and we'll see what's possible.

End-of-tenancy cleans work best in an empty property. Furniture and possessions in the way give you a worse result than you're paying for. If you can't be out, talk to us — we can clean in stages, or go in after the removals firm is done.

Yes. EU Ecolabel products are standard here too. That means no lingering chemical smell, no harmful residues in drains, and it's safe if whoever moves in has children, pets or allergies.

Yes, but it's a separate job because the kit is different. Let us know during the site survey if there's been refurbishment in the last few months — we'll factor it into the quote and make sure adhesive residue, paint splatter and sanding dust actually come off.

Because the price depends on the actual condition of the property, and we won't promise something we can't deliver. A 60 m² flat in perfect nick costs a third of an equivalent flat that's been let for 8 years with no interim clean. The site survey takes 15–20 minutes and is free — you walk away with a real number, not an estimate.
