Timescales vary significantly by job type, property size, and the number of asbestos-containing materials (ACMs) involved. This guide provides typical survey-to-clearance-certificate timelines for the most common domestic and commercial removal scenarios.
All timescales are from first contact to receipt of air clearance certificate. They assume a site survey is carried out before work begins and that the job proceeds without delays. Timescales are indicative — your quote will include a specific programme.
| Job type | Survey | Removal | Air clearance | Total |
|---|---|---|---|---|
| Single garage roof (asbestos cement) | 1–2 hrs | 1–2 days | 1 day | 3–5 days |
| Double garage roof (asbestos cement) | 1–2 hrs | 2–3 days | 1 day | 4–6 days |
| Artex ceiling (1 room) | 1–2 hrs | 1 day | 1 day | 3–4 days |
| Artex ceiling (whole house) | 2–3 hrs | 3–5 days | 1–2 days | 6–10 days |
| Asbestos floor tiles (1 room) | 1 hr | 1 day | 1 day | 3–4 days |
| Asbestos flue pipe or downpipe | 1 hr | 0.5–1 day | 1 day | 2–3 days |
| Asbestos soffit boards (terraced house) | 1–2 hrs | 1–2 days | 1 day | 3–5 days |
| Commercial — multiple ACM types | Half day–1 day | 3–10 days | 1–2 days | 1–3 weeks |
* Timescales assume standard access and no structural complications. Jobs involving base slab repair, reinstatement, or multiple ACM types will take longer.
A job with multiple ACM types — cement roof, Artex ceiling, and floor tiles — will take longer than a single-material removal. Each ACM type may require a different removal method and a separate containment setup.
Restricted access — scaffolding requirements, confined spaces, or working around occupied areas — adds time. We factor this into the programme when we carry out the site survey.
If the removal includes reinstatement — a replacement roof, replastered ceiling, or new floor — the total programme will be longer. We quote for removal and reinstatement together so there are no surprises.
Air clearance must be carried out by an independent UKAS-accredited analyst. In most cases we can schedule this for the day after removal. In busy periods, there may be a 1–2 day wait.
From our work
A property manager in Deptford needed a garage roof removed before a tenant moved in. The previous contractor had quoted five days and a start date three weeks away. The property manager needed the job done in a week.
We visited the site the following morning. The garage was a standard single-skin asbestos cement roof in good condition — no broken sheets, no base slab complications, straightforward access. We quoted two days: one day for removal and containment, one day for air clearance. We started three days later.
The five-day quote from the previous contractor was not wrong — it was simply based on a standard programme that did not account for the specific conditions of this job. A site visit before quoting is the only way to give an accurate timeline. A quote produced from a photo or a description will always carry more contingency than one produced after a proper survey.
We visit your site, assess the job, and provide a programme of works with your quote. No guesswork.
