Asbestos Bitumen & Mastic Removal Cost UK
Asbestos-containing floor bitumen removal typically costs £38–£65/m² + VAT. Accessible asbestos-containing mastic around windows and doors costs £25 per linear metre + VAT where the frame has already been removed or the mastic is accessible in front of the retained frame.
How much does asbestos bitumen or mastic removal cost?
The appropriate pricing method depends on where the asbestos-containing product has been used. Floor adhesive is normally measured by square metre, while accessible mastic around windows and doors is more accurately measured in linear metres.
Asbestos bitumen adhesive removal
£38–£65/m² + VATFor controlled removal of asbestos-containing bitumen adhesive from suitable floor substrates.
The final rate depends on floor area, adhesive thickness, adhesion, substrate condition and the completion standard required before new flooring.
Accessible asbestos mastic removal
£25/lm + VATApplies where the frame has already been removed or where the asbestos-containing mastic is directly accessible in front of the existing frame.
Frame removal, concealed mastic and specialist access are priced separately.
Important £25/lm qualification
The £25 per linear metre rate assumes ASM has direct access to the asbestos-containing mastic.
It does not automatically include removing the window or door, dismantling retained frames, scaffolding, MEWP access or making good after frame removal.
Asbestos bitumen adhesive on floors
Black and dark-brown bituminous adhesives were widely used beneath older thermoplastic, vinyl and other floor coverings.
The asbestos fibres are normally firmly held within the dense bitumen matrix, so this product is very different from friable asbestos insulation.
Typical projects include:
- bitumen remaining after floor-tile removal;
- adhesive across concrete floors;
- adhesive on screed;
- localised adhesive residues;
- multiple historic flooring layers;
- removal before replacement flooring is installed.
ASM's standard guide for bitumen-only removal is £38–£65/m² + VAT.
Example asbestos bitumen removal budgets
These examples simply apply the £38–£65/m² guide and are intended for initial budgeting rather than as fixed quotations.
Small jobs can remain subject to normal mobilisation requirements.
Useful for room or small commercial refurbishment budgeting.
Larger continuous areas can offer improved working efficiency.
Useful for commercial tender or refurbishment allowances.
Doorways, edges and repeated setup can increase labour per square metre.
Large uninterrupted areas can sit nearer the lower range where substrate and adhesive conditions are favourable.
What determines the floor-bitumen rate?
| Factor | Lower-cost condition | Higher-cost condition |
|---|---|---|
| Floor area | Large continuous floor | Several small rooms |
| Bitumen thickness | Thin residual adhesive | Heavy continuous layer |
| Adhesion | Releases relatively readily | Strongly adhered |
| Substrate | Sound smooth concrete | Porous, weak or damaged substrate |
| Floor layers | Bitumen already exposed | Other floor finishes remain |
| Access | Clear open area | Furniture, plant or restricted access |
| Edges | Simple room geometry | Numerous thresholds and detailed edges |
| Completion standard | Normal asbestos-removal finish | More demanding substrate preparation |
Window and door asbestos mastic removal costs
Where asbestos-containing mastic is directly accessible, linear-metre pricing provides a simple way to cost both individual refurbishment work and larger window or door replacement programmes.
Subject to normal mobilisation and site requirements.
Suitable as a small programme allowance.
Useful for phased refurbishment works.
Suitable for larger planned frame-replacement programmes.
Gives direct access to the asbestos-containing mastic bead.
Frame dismantling or removal materially changes the work scope.
Example calculations are not minimum call-out prices
The examples demonstrate the £25/lm unit rate. Small projects can remain subject to mobilisation, travel, induction, access and other site requirements.
When does the £25/lm window and door mastic rate apply?
Standard £25/lm basis
- Frame has already been removed
- Or mastic is exposed in front of retained frame
- Mastic is directly accessible
- Normal bonded material condition
- Controlled hand removal is suitable
- No specialist high-level access required
Separately priced
- ASM removing window or door frame
- Mastic concealed behind retained frame
- Complex frame dismantling
- Scaffold
- MEWP
- Multiple mastic layers
- Substantial making good
- Other ACMs around the opening
Is asbestos bitumen or mastic removal licensed work?
Suitable controlled work on firmly bonded asbestos-containing mastics, sealants and floor adhesives is generally at the lower-risk end of asbestos removal. The actual task and method must still be properly assessed before work begins.
| Task | HSE guidance | ASM approach |
|---|---|---|
| Asbestos floor tiles and mastic | HSE A23 provides a non-licensed task method for appropriate asbestos-containing floor tiles and mastic. | Controlled removal following project-specific RAMS. |
| Window / door mastic | HSE A37 covers asbestos-containing mastic, sealant, beading, filler, putty and fixing materials as a non-licensed task. | Controlled removal using appropriate hand methods. |
| Mastic attached to AIB or lagging | HSE A37 states that the task sheet is not appropriate where the material is attached to AIB or lagging. | Higher-risk asbestos route assessed separately. |
| Mechanical abrasion | HSE guidance says not to sand asbestos flooring and A37 says not to use power tools for routine mastic removal. | Not included within standard £38–£65/m² pricing. |
Standard bitumen pricing does not include uncontrolled grinding
HSE A23 states that asbestos flooring should not be sanded, while A37 says power tools should not be used for routine mastic, sealant and putty removal.
If the follow-on flooring specification requires aggressive mechanical preparation, that requirement must be assessed separately rather than simply applying the £38–£65/m² asbestos-removal rate.
Tiles, bitumen and paper-backed flooring have different costs
| Flooring scope | ASM guide | Notes |
|---|---|---|
| Tiles only — larger/open areas | From £20/m² + VAT | Suitable larger continuous areas. |
| Tiles only — smaller rooms | Around £35/m² + VAT | Higher effective labour/mobilisation cost. |
| Tiles + asbestos bitumen | £45–£65/m² + VAT | Combined flooring-removal project. |
| Bitumen only | £38–£65/m² + VAT | Where adhesive is already exposed. |
| Asbestos-paper-backed flooring | Site-specific | HSE A23 identifies removal of asbestos-paper-backed flooring as NNLW. |
What we check on bitumen and mastic projects
Survey information, measurements and photographs can often allow straightforward projects to be priced before attendance.
What is included within controlled mastic removal?
Confirm which adhesive, sealant or mastic contains asbestos and define the work boundary.
Restrict access and establish appropriate protection, PPE/RPE, cleaning and asbestos-waste controls.
Remove the ACM using controlled methods suited to the material and substrate while avoiding unnecessary abrasion.
Remove residues to the agreed standard, clean the area and package asbestos waste correctly.
Linear-metre pricing helps budget window and door replacements
The £25/lm structure is particularly useful where housing, commercial or public-sector clients are replacing multiple windows or doors and the asbestos survey has identified mastic consistently around the frames.

Coordinate the asbestos works with the wider refurbishment
Bitumen and mastic removal commonly forms an enabling package ahead of replacement flooring, windows, doors or wider refurbishment.
ASM undertakes suitable non-licensed and notifiable non-licensed asbestos work internally. Where a project requires licensed asbestos controls, the licensed route is available within F&I Group through Flowing Construction Services under licence 202505985.

Asbestos sampling and laboratory analysis
Old black adhesive, window mastic and sealing compounds cannot be confirmed as asbestos-containing from appearance alone.
Where suitable existing asbestos information is unavailable, ASM can provide appropriate sampling and analysis before the refurbishment programme begins.
ASM holds UKAS accreditation number 32982 for defined asbestos inspection and testing activities within its accredited schedules.
