What We Do

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.

How We Work

Four steps. No surprises.

1. Free on-site estimate — Call or message and we'll come look at the job in person. You get a written quote — line items, materials, timeline — usually within 24 hours.
2. Plan & schedule — We agree on scope, materials and start date in writing. No verbal hand-shakes that turn into change orders later.
3. Build & finish — Our own crews show up, on time, with the right tools. You get a single point of contact, daily progress, and a tidy site at the end of every day.
4. Walk-through & warranty — We don't call a job done until you do. Final walk-through, deficiency list cleared, written workmanship guarantee in your hand.

Frequently Asked Questions

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.
