“How much does concrete cutting cost?” is usually one of the first questions asked when planning a renovation, retrofit or construction project in Ottawa.
The short answer is that there is no dependable flat rate for every job. A short cut through an accessible concrete floor is very different from creating an opening in a reinforced foundation wall or drilling multiple holes inside an occupied commercial building.
Concrete-cutting costs in Ottawa depend on the cutting method, concrete thickness, reinforcement, site access, safety requirements and the amount of material that must be removed. Understanding these factors will help you request a more accurate quote and avoid unexpected changes once work begins.
Why Concrete-Cutting Prices Vary
A professional concrete-cutting contractor must select the equipment and procedures that match the actual conditions at the job site.
The quote has to account for more than the visible length of a cut. The contractor may also need to consider:
- What is embedded inside the concrete
- Whether the surface is horizontal, vertical or overhead
- The size and weight of the concrete section
- Access to power and water
- Dust, slurry and noise controls
- Protection for surrounding finishes
- Concrete handling, removal and disposal
Two openings with identical dimensions can therefore require very different amounts of labour, equipment and preparation.
1. The Concrete-Cutting Method Required
The cutting method is one of the largest factors affecting the scope and price of the work.
Slab Sawing
Concrete slab sawing is normally used on horizontal surfaces such as concrete floors, driveways, roads, bridge decks and suspended slabs.
Common slab-sawing applications include:
- Plumbing and electrical trenches
- Expansion and control joints
- Damaged slab removal
- Road and pavement repairs
- Openings for new building services
Wall Sawing
Concrete wall sawing uses track-mounted equipment to make controlled cuts through vertical or angled concrete surfaces.
It is commonly used to create:
- Door openings
- Basement windows
- Stairway openings
- Mechanical penetrations
- Structural openings
- Openings for building additions
The setup, support and handling requirements for a wall opening may differ substantially from those for a horizontal floor cut.
Core Drilling
Concrete core drilling creates accurate circular openings in walls, floors and other concrete structures.
These penetrations are frequently needed for:
- Plumbing pipes
- Electrical conduit
- HVAC systems
- Dryer and exhaust vents
- Sprinkler systems
- Communication cables
- Concrete testing
For core drilling, the diameter, depth and number of holes all affect the quote.
Wire Sawing
Concrete wire sawing may be required for extremely thick, heavily reinforced or unusually shaped structures that cannot be handled efficiently with a conventional circular blade.
Wire sawing is generally associated with specialized industrial, infrastructure and structural-modification projects. Learn more in Titan’s guide to wire sawing when precision really matters.
Some projects require more than one cutting method. A contractor must assess the location, concrete and intended result before recommending the right equipment.
2. The Size and Depth of the Cut
A contractor will need the approximate length, width and depth of every proposed cut or opening.
Deeper cuts take more time and place greater demands on blades and equipment. A large wall opening may also need to be divided into smaller sections so the concrete can be supported, lowered and removed safely.
For core drilling, both the diameter and depth of each hole matter. A small conduit penetration will not require the same equipment or operating time as a large mechanical opening through thick reinforced concrete.
Providing accurate measurements during the quotation stage helps reduce uncertainty and allows the contractor to select the appropriate equipment.
3. Concrete Type and Reinforcement
Concrete frequently contains rebar or wire mesh. Some structures may also contain post-tension cables, electrical conduits, plumbing lines or communication services.
Diamond cutting equipment can penetrate reinforced concrete, but that does not mean reinforcement should be cut without investigation or approval. Encountering steel can also affect cutting speed and equipment wear.
Post-tension cables and active utilities present much more serious risks. Damaging one may:
- Create an immediate safety hazard
- Affect structural performance
- Interrupt electrical or mechanical services
- Require expensive repairs
- Delay the construction schedule
Any available structural drawings, renovation records or information about the building should be shared with the contractor before work begins.
4. Concrete Scanning and Pre-Cutting Investigation
Concrete scanning may be recommended before cutting or coring to identify embedded objects and help determine a safer cutting location.
Scanning is especially important when:
- Cutting or drilling structural concrete
- Working with a suspended slab
- Working with post-tensioned concrete
- Building records are incomplete
- Electrical or mechanical services may be present
- Work is taking place in an occupied building
- Relocating the opening would be less expensive than striking an obstruction
Scanning adds a planning step, but it can help prevent property damage, downtime and unexpected repairs. It should be viewed as a risk-management measure rather than an unnecessary expense.

5. Site Access and Working Position
Easy access helps crews move equipment, manage water and remove concrete efficiently. Restricted access can require smaller equipment, additional handling or more setup time.
Factors that can affect the quote include:
- Stairs, narrow doors or limited elevator access
- Work in a basement or confined room
- Limited space around the cutting location
- Vertical or overhead cutting
- Work at height
- Nearby equipment or finished surfaces
- Traffic and pedestrian-control requirements
- Limited parking or loading access
Photos showing the route from the building entrance to the work area can be extremely useful when requesting a quote.
The contractor should also know whether equipment can be positioned close to the cutting location and whether other trades will be working in the area.
6. Indoor Work, Dust Control and Slurry Management
Concrete cutting can create dust, water and slurry. The control measures needed depend on the cutting method, equipment and surrounding environment.
Indoor projects may require:
- Electric cutting equipment
- Water collection
- Slurry containment
- Surface protection
- Ventilation
- Dust-control equipment
- Temporary barriers
- Coordination with building occupants
These considerations are especially important in offices, hospitals, retail spaces, commercial buildings and occupied homes.
Tell the contractor whether the building will remain occupied and whether there are sensitive finishes, equipment or operations near the work area. A properly planned job protects the site and makes final cleanup more predictable.
7. Concrete Breaking, Removal and Disposal
Cutting the concrete and removing it are separate parts of the project.
Concrete sections can be extremely heavy. Large pieces may need to be divided, supported, lowered and transported using specialized equipment. The route out of the building can also affect the amount of labour required.
Before approving a quote, confirm whether it includes:
- Breaking the cut concrete into manageable pieces
- Supporting and lowering concrete sections
- Carrying or moving the material
- Loading and transportation
- Disposal or recycling
- Slurry collection
- Final cleanup
- Protection for surrounding areas
Titan provides professional concrete breaking and removal for projects where both cutting and material removal are required.

How to Get a More Accurate Concrete-Cutting Quote
Providing detailed information at the beginning can shorten the quotation process and help prevent misunderstandings.
Include the following whenever possible:
- The Ottawa-area project address
- Photos of the cutting location
- Photos showing access to the work area
- The number and dimensions of the proposed cuts or holes
- The approximate concrete thickness
- The purpose of each opening
- Available drawings or scanning information
- Whether the concrete must be removed
- Whether the building will remain occupied
- Your preferred schedule or project deadline
Marking the proposed openings directly on photographs can help the estimator understand the project.
For more complicated projects, a site visit may be necessary before a firm scope and price can be prepared.
What Should a Concrete-Cutting Quote Include?
Comparing two bottom-line prices can be misleading if the contractors have included different services.
A complete quote should clearly explain whether it covers:
- Equipment and crew mobilization
- Cutting or core drilling
- Concrete scanning
- Site and surface protection
- Dust, water and slurry control
- Concrete handling
- Removal and disposal
- Cleanup
- Additional work if unexpected conditions are found
Ask whether there are assumptions concerning concrete thickness, reinforcement, access or available power and water.
A clearly defined scope makes it easier to coordinate other trades and keep the project on schedule.
Frequently Asked Questions About Concrete-Cutting Costs
Is concrete cutting priced by the hour or by the project?
Pricing practices vary, but many jobs are quoted based on the complete scope. Dimensions, depth, concrete type, access, setup and removal requirements may all be considered.
Ask what the quote includes instead of comparing only an hourly or per-cut rate.
Can concrete-cutting equipment cut through rebar?
Specialized diamond equipment can cut reinforced concrete. However, reinforcement should not be cut automatically. Scanning, structural drawings or direction from the appropriate project professional may be required before altering structural concrete.
How deep can a concrete saw cut?
Cutting capacity depends on the equipment, concrete and site conditions. Slab and wall saws handle many conventional applications, while wire sawing can be considered for exceptionally thick, heavily reinforced or difficult structures.
Do I need concrete scanning before cutting?
Scanning is commonly recommended when embedded utilities, reinforcement or post-tension cables may be present. The appropriate level of investigation depends on the structure and the consequences of striking an embedded object.
Can concrete cutting be performed indoors?
Yes. Indoor projects can be completed using suitable equipment and a plan for dust, water, slurry, ventilation and surface protection. The contractor should know whether the building will remain occupied.
Is concrete removal included in the cutting price?
Not always. Confirm whether the quote covers cutting only or also includes breaking, handling, transportation, disposal and cleanup.
Can Titan quote from photographs?
Photographs, measurements and project drawings can help with the initial assessment. Depending on the complexity and site conditions, Titan may need additional information or a site visit before confirming the final scope.
