About us

One contractor, every stage of the build.

Welcome to Ottawa Zain Construction Inc. We’re a hands-on residential contractor based in Ottawa, with a reputation built one driveway, one basement, and one kitchen at a time. Our crews are equipped to handle the parts of a renovation most companies sub out — foundation work, waterproofing, interlock, hardwood, paint and finish carpentry — so the same team that starts your job is the one who finishes it.

With over 570 completed projects, our work speaks louder than our marketing. We show up when we say we will, we leave the site cleaner than we found it, and we stand behind every square foot we install.

What we do

Every trade you need.
One accountable team.

Whether you need cracks in the foundation sealed before winter or a tired kitchen turned into the heart of the home, here’s what we install, repair and finish — in-house.

Foundation Repair

Cracks, settling, bowing walls and structural concerns — diagnosed and repaired with proper engineering, not patch jobs.

Foundation Waterproofing

Excavation, membrane, drainage and interior sealing for dry, healthy basements that pass inspection and survive Ottawa winters.

Interlock & Hardscape

Driveways, walkways, patios and retaining walls. Properly graded, compacted and edged so they stay level for decades.

Floor Laying & Refinishing

Hardwood, engineered, laminate and vinyl plank install. Sand, stain and refinish existing floors back to showroom condition.

Tile & Flooring

Porcelain, marble-look, mosaics and large-format tile for kitchens, bathrooms, foyers and basements — with proper underlayment and waterproofing.

Interior & Exterior Painting

Walls, ceilings, trim, accent walls, garage doors and exteriors. Proper prep, premium products and clean lines — not a roller and a rush.

Kitchen Planning & Renovation

From layout and cabinet selection to plumbing, tile, countertops and lighting — we plan, project-manage and execute the whole renovation.

Bathroom Renovation

Full bathroom remodels — tile shower surrounds, soaker tubs, vanities, plumbing and waterproofing — finished to a luxury-feel standard.

Common questions

FAQ

Do you charge for estimates?

No. On-site estimates within our service area are free. We’ll measure, take notes, and follow up with a written quote.

Are you licensed and insured?

Yes — Ottawa Zain Construction Inc. carries liability insurance and operates as a registered Ontario corporation. We can provide a certificate before any work begins.

How long does a typical kitchen renovation take?

Most kitchen renovations run 3–6 weeks depending on scope, cabinet lead times and whether structural changes are involved. We give you a written timeline before we start.

Can you handle waterproofing in winter?

Exterior excavation work is weather-dependent, but interior waterproofing, sump pumps and crack injection can typically be done year-round.

Do you pull permits?

When the work requires a City of Ottawa building permit, yes — we handle the application and inspections as part of our scope.

How do payments work?

A reasonable deposit on signing, progress payments tied to milestones, and a final payment on completion after walk-through. Everything is laid out in the written contract.
