Trenching Services in Newmarket — Utility, Drainage, Pool Lines

OCM Excavation runs trenching crews across Newmarket every week — water service replacements off Main Street, gas and electrical runs in Glenway, drainage lines in Stonehaven, and pool feeds in Woodland Hill. We cut clean, lay proper bedding, and backfill in lifts so your trench does not settle six months later. Whether you need a 30-metre water service or a short conduit run to a new shed, we have the right machine for the cut. Call 416-317-3090 for a quote.

What We Trench in Newmarket

Trenching is rarely a stand-alone job. Most Newmarket calls combine a utility run with another scope — a pool excavation, a foundation repair, a new deck, or a regrade. Our trenching contractor crews handle:

• Water service trenches — copper or PEX from the property line to the house, typically 1.5 m deep below frost.
• Gas line trenches — coordinated with Enbridge, depth and bedding per their spec.
• Electrical and low-voltage conduit — to detached garages, pool equipment pads, sheds, EV chargers, landscape lighting.
• Drainage and weeping tile trenches — perimeter foundation drains, downspout extensions, sump discharge lines, swale tie-ins.
• Pool plumbing and bonding trenches — skimmer, return, suction, and bonding wire from pool to equipment pad.
• Irrigation main lines — sleeves under driveways, mains to zone valves.

Every trench gets the same treatment: clean vertical walls where soil allows, proper bedding sand or stone under the pipe, marker tape above, and backfill compacted in 200 mm lifts. That is how a trench stays put.

How We Work in Newmarket Neighbourhoods

Newmarket is not one type of property. Historic Downtown near Main and Water has tight lots, mature trees, and heritage hardscape that does not tolerate a tracked machine on the front lawn. Glenway and Summerhill Estates have wider side yards but established landscaping you do not want torn up. Stonehaven runs to estate lots with longer service runs. Woodland Hill is newer build with utility congestion already mapped.

We size the machine to the property. A 1.7-tonne mini-excavator fits through a 1-metre gate for downtown lots. A 3.5-tonne handles longer runs in Stonehaven without churning the lawn. For tight corridors we hand-dig the last few metres rather than chew up your interlock. If your job is small enough that a stand-alone mini does it, our mini-excavator service in Newmarket page covers that scope.

Locates, LSRCA, and Tree Protection

Every trench starts with an Ontario One Call locate. We will not put a bucket in the ground without painted utilities — too easy to clip a gas line or a Bell drop and turn a one-day job into a week. Locates are free, and we book them five business days before the dig.

If your property sits near the East Holland River corridor or any tributary, the Lake Simcoe Region Conservation Authority (LSRCA) regulates work under Ontario Regulation 41/24. That can include trenches inside the regulated buffer. We flag this at the site visit and either keep the trench outside the regulated area or help you get the LSRCA permit started before we mobilize. LSRCA is at 905-895-1281 if you want to confirm.

Newmarket also protects private trees over 20 cm DBH (diameter measured at 1.4 m above grade). If a trench needs to pass within the critical root zone of a regulated tree, we route around it, hand-dig, or help you apply for the Private Tree Protection permit before we cut. We do not want to be responsible for killing a 60-year-old maple on a Glenway lot, and the by-law fines are not small.

Typical Trenching Jobs and What They Involve

A 20-to-30-metre water service trench in Newmarket usually runs one to two days end-to-end: locates first, then dig, pipe drop, bedding, pressure test, backfill, and surface restoration. A short conduit run to a detached garage in Historic Downtown is often a half-day if access is clean. Pool plumbing trenches are scheduled inside the larger pool excavation window so we are not opening and closing the same ground twice.

We do not quote trenching by the linear foot over the phone — depth, soil, locates, restoration, and access change the number too much. We come out, measure, walk the line, and give you a fixed scope. Call 416-317-3090 or use the form on our free quote page.

Why Newmarket Homeowners Call OCM

• We run our own machines and crews — no subbing the dig out.
• We work across the GTA and York Region every day, so we know LSRCA, York Region Water, and Newmarket by-law process.
• We restore what we dig through — sod, interlock, gravel, asphalt — so the property does not look like a trench scar for a year.
• We give you a fixed price after the site visit, not a surprise invoice at the end.

Other service areas across the region are listed on our service areas page if you have a second property elsewhere in the GTA.

Frequently Asked Questions — Trenching in Newmarket

How deep does a water service trench need to be in Newmarket?

Below the local frost line, which in Newmarket means roughly 1.5 metres of cover over the pipe. Gas lines are shallower per Enbridge spec, and low-voltage conduits can run shallower again with marker tape and sleeve protection. We confirm the depth required by the utility or by York Region Water for each specific line before we cut.

Do I need a permit to trench on my own Newmarket property?

The trench itself usually does not need a Newmarket building permit, but the work it serves often does — a new water service, a pool, a detached structure with power. If the trench crosses a regulated tree’s root zone or sits inside the LSRCA regulated area along the East Holland River, separate approvals apply. We tell you which approvals your job triggers at the site visit.

Can you trench without tearing up my lawn or interlock?

Mostly. We use narrow buckets, lay plywood or matting on lawns, and hand-dig final approaches to interlock or steps. Sod gets lifted in strips and re-laid. Interlock gets pulled, stored, and reset. We do not promise zero disturbance — that is not honest on a trench job — but we keep the disturbed footprint as small as the work allows.

How long does a typical trenching job take?

A short utility run to a shed or pool pad is often half a day to a day. A full water service replacement from the property line to the house is one to two days. Drainage trenches around a foundation can take two to four days depending on length and waterproofing scope. Locate scheduling adds five business days up front.

Do you handle the Ontario One Call locate?

Yes. We book the locate, meet the locators if needed, and do not start digging until the paint and flags are down. If a private locate is required for non-utility lines on your property — old irrigation, landscape lighting, septic — we can arrange a private locator before we cut.

Do you trench in winter in Newmarket?

Yes, with caveats. Frozen ground slows the dig and surface restoration has to wait until spring for sod, asphalt, and interlock work. Emergency water service breaks we handle through winter. Pool and drainage trenches are usually better scheduled spring through fall so we can close out restoration in the same visit.
