About Us
Clairmont Construction is Ottawa's trusted bathroom and basement renovation company, serving Nepean, Kanata, Barrhaven, and Orleans with licensed, insured, design-led renovations
Who We Are
Clairmont Construction is Ottawa's dedicated bathroom and basement renovation company, built around a simple belief: homeowners deserve a contractor who specializes, not one who spreads their attention across every trade. We focus exclusively on bathroom renovations and basement renovations for homeowners across Ottawa, Nepean, Kanata, Barrhaven, Orleans, and the surrounding communities of Stittsville, Manotick, and Riverside South. Our specialist approach means every bathroom renovation and every basement renovation benefits from real, focused expertise — not a generalist contractor learning as they go.
Our bathroom renovation services in Ottawa range from full gut renovations and walk-in shower conversions to custom vanity installations, heated flooring, and complete tile work. For homeowners looking to transform an outdated bathroom into a spa-inspired retreat, our design-led process ensures every detail — from layout to lighting to fixtures — is considered before construction begins. Our basement renovation and basement finishing services turn unused space into real, livable square footage, whether that means a basement bathroom addition, a finished rec room, a home theater, or a fully developed lower level built to Ontario code.
Every Clairmont Construction project begins with a free in-home consultation, where we discuss your renovation goals, walk through your space, and provide a transparent, itemized quote with no hidden costs. From there, our team manages material selection, construction, and coordination of licensed trades for electrical and plumbing work — ensuring every part of your Ottawa bathroom or basement renovation meets code and holds up over time. We are fully licensed and insured, backed by $2M in liability coverage, and committed to a 24-hour quote turnaround for every homeowner who reaches out.
Whether you're renovating a bathroom in Kanata, finishing a basement in Barrhaven, or planning a full home renovation in Ottawa's core, Clairmont Construction brings the same specialist-level care and attention to every project. It's a focused approach to renovation that means real expertise, honest communication, and a finished space that adds genuine, lasting value to your Ottawa home.

What People Are Saying
“Clairmont did an awesome job replacing my carpet with vinyl flooring and hardwood stairs. The results look fantastic, and they even painted my walls perfectly. The team was friendly, professional, and super easy to work with. Highly recommend them if you need quality work done!”

— Paolo

“Where do I start with the boys at Vanguard Contracting. I had basement redone and it hasn’t looked this great in years. The contractor was very clean and on time with his work and at a fraction of the cost! I highly recommend their service.”
— Sadek Kanta, Ottawa ON
Why Specialization Matters
Most contractors in Ottawa offer everything — kitchens, additions, commercial builds, bathroom renovations, basement renovations — spreading their attention across every trade. Clairmont Construction does the opposite. By focusing exclusively on bathroom renovation and basement renovation projects across Ottawa, Nepean, Kanata, Barrhaven, and Orleans, our team develops real, repeated expertise in exactly two areas, rather than a surface-level understanding of many.
The result is fewer surprises, more accurate itemized quotes, and a finished bathroom or basement renovation built by a team that has solved the specific challenges of walk-in showers, basement bathroom additions, and basement finishing many times before — not one learning as they go with your Ottawa home.
