Company Background
About Omni Basement Systems
With 273 Google reviews and a 4.6 average, Omni Basement Systems has a deep review record for a Hamilton waterproofing contractor. Pete Karreman started the company in 2003, and it now works from a staffed office at 95 Frid Street Unit 1, with a named team of system design specialists, crew leaders and installation technicians on its website.
Omni is the local dealer for the Basement Systems contractor network, which gives it patented drain and sump products and factory training. Services include interior subfloor drain tile, baseboard drainage, negative side sealant, exterior excavation, sump pumps with battery backup, wall and floor crack repair, crawl space vapor barriers and insulation, wall anchors for foundation repair, and the Aspen air purifier. Most systems come with a fully transferable 25 year warranty, and written terms arrive with the estimate. Financing is offered, with a 10 percent minimum deposit.
The service area on the company site includes Hamilton, Dundas, Stoney Creek, Binbrook, Grassie, Millgrove, Burlington, Oakville and the Niagara region. Hamilton testimonials on the site come from homeowners on Kenilworth Avenue South, Brucedale Avenue East, Cheryl Avenue and Fernwood Crescent. Reviews praise the crews for protecting carpet and stairs. One reviewer said Gord and Dane were on site at 9:00 and gone before 2:00, with photos sent along the way. Another, Glenn, described breaking the concrete floor and digging about three feet down without leaving a pebble behind. Omni rates 4.6 from 273 Google reviews, read October 21, 2026, and the site lists BBB accreditation and several HomeStars Best of awards.
Omni suits homeowners who want an interior drain and pump system from an established crew, and who value a warranty that passes to the next owner. It suits less well anyone who needs weekend availability, since the office keeps weekday hours, or a buyer who is not yet the owner and pays a $195 estimate fee credited toward the work. Before booking, ask which method they recommend for your walls, what the warranty excludes, and who pulls the City of Hamilton permit. Ontario has no waterproofing specific licence, so confirm a current WSIB clearance certificate, liability insurance and the permit instead.

Omni Basement Systems FAQs
Do waterproofing contractors in Hamilton need a licence, and is Omni Basement Systems credentialed?
Ontario has no waterproofing specific licence, so check a current WSIB clearance certificate, liability insurance and the City of Hamilton permit before work starts. Omni Basement Systems lists BBB accreditation, a dealer relationship with the Basement Systems contractor network and an affiliation with Foundation Supportworks on its site. It also reports several HomeStars Best of awards. Ask for the clearance certificate and insurance certificate in writing, and ask who applies for any permit.
What are Omni Basement Systems' hours, and do they do emergency calls?
The office is open Monday to Thursday from 8 AM to 5 PM and Friday from 8 AM to 4 PM, and it is closed weekends, according to Google. The company site does not advertise 24 hour or emergency service. Its office is staffed, so you reach a person during those hours rather than an answering service. Call 289-769-8994 and ask how soon an inspection can be booked.
What warranty and financing does Omni Basement Systems offer in Hamilton?
Most Omni systems come with a fully transferable 25 year warranty, and the written terms are provided with the estimate.
