How to Choose an Excavation & Demolition Contractor in Kelowna

Hiring someone to dig, trench, grade, or tear down a structure is a bigger commitment than most trades work: heavy machines arrive on your property, the ground opens up, and whatever is found underground becomes part of your project. Choosing well comes down to a clear scope, quotes that show where the money goes, locates and permits handled before the machines roll, and insurance that covers this kind of work. This guide walks through each step.

Define the job before anyone quotes it

Excavation and demolition are priced around machine time, trucking, and disposal, so a vague scope guarantees a vague price. Before you call anyone, write down the following.

• Dig or demolition: moving earth for a foundation, driveway, or pool is a different job from tearing down a garage or house.
• Site access: gate and lane width, fencing that has to come down, overhead power lines, and landscaping or septic areas to protect.
• What you know about the ground: soil type, drainage problems, a high water table, or old buried tanks and fill.
• What finished looks like: levelled and graded, backfilled and compacted, topsoil spread, and every load of debris hauled away.
• Your timeline, and how long the site can stay opened up.

Get two or three written quotes you can compare

Send the same written scope to two or three local contractors. Excavation quotes carry costs that are easy to hide in one lump sum: getting machines to your property, trucking, disposal, and the finishing work at the end. A quote that skips those lines is not cheaper, just less complete.

1. Send every contractor the same written scope, including access details.
2. Ask each to itemise mobilisation, machine hours, haul-off and disposal by the load, backfill and grading, compaction, and any retaining or shoring the job needs.
3. Ask what happens if the crew hits rock, water, or something unexpected, and how a change in price gets approved.
4. Ask for proof of liability insurance, and if the contractor has workers, a WorkSafeBC clearance letter showing they are covered.
5. Confirm who supplies fill and topsoil, the quote's validity period, and the payment schedule.

Locates, permits, and asbestos surveys come first

Before anyone digs, underground lines must be marked. In British Columbia that starts with a free locate request to BC 1 Call — click or call before you dig — submitted online any time or by phone, with member utilities responding to locate requests within three business days. Confirm in writing whether you or the contractor files it. For demolition, WorkSafeBC requires asbestos to be identified before work that could disturb it: a qualified professional surveys the building, and if asbestos is found it must be removed by a licensed abatement contractor, with a notice of project submitted to WorkSafeBC, before the structure comes down. Asbestos was widely used in B.C. buildings until the early 1990s, so age alone tells you little. Permit rules vary by project, so confirm with the City of Kelowna what your job needs and who arranges it.

Red flags worth pausing for

• A contractor willing to dig before the BC 1 Call locates are done.
• A demolition quote that never mentions a hazardous-materials or asbestos survey.
• One lump-sum number with no breakdown of mobilisation, machine time, trucking, or disposal.
• No proof of liability insurance or coverage for the crew and machines working on your property.
• A price that climbs once the site is open, with changes approved only by a handshake.
