Editorial Review

Our Take on Above Grade Construction Services

Above Grade Construction Services earns its spot on responsiveness and crack repair work, backed by a founder with commercial waterproofing experience at ProBond. It is a multi-trade contractor rather than a pure waterproofer, and its guarantee terms are not published, so get them in writing.

  • Founder Zach Haggerty worked at ProBond, a large commercial waterproofing company, before starting the firm in 2020
  • Offers crack injection (polyurethane and epoxy), exterior membranes, weeping tile, interior drainage and sump pumps

Things to Consider

  • Most reviews describe crack repair, so ask for examples of full exterior excavation if that is the job; Google lists weekday hours while the site says Mon-Sat

    I used Above Grade for a large scale installation project across around 200 Condominium Units, including an inspection. They delivered on this project with no disruption to the Owner's. It was easy to work with Myles and Zach and they met with Board Member's following the project to ensure we were satisfied. I'll use this company for future projects and would recommend them to other Condominium Managers/Boards.

    Great company. The owner, Myles, was very accommodating and made sure the job could get done with my limited availability. I can't remember the technician's name who did the work, but he was also great and explained the whole process clearly.

  • Graham Samycia5.0

    They were extremely accommodating. I was in a real rush to get a foundation crack repaired, and they were able to adjust some scheduling to get it done as quickly as possible for us. They did a great job very professional, and I’m very confident there will be no issue with their repair.

Company Background

About Above Grade Construction Services

A contractor renovating a basement suite in Edmonton had foundation leaks to sort out and wrote that Above Grade Construction Services met him the day after he called, gave the estimate that same day, and had a worker fixing the problem two days later with no more leaks afterward. That speed shows up again and again in the company's reviews, and it is the reason this Edmonton firm earns a place on the list.

Zach Haggerty founded Above Grade Construction Services in 2020. According to the company's own about page, he comes from a family of stucco plasterers, worked at ProBond, a large commercial waterproofing company in Western Canada, and later handled project management at Bird Industrial. The company works from 16647 113 Ave NW and says it serves Edmonton, Sherwood Park, St. Albert, Beaumont, Leduc, Spruce Grove and Fort Saskatchewan.

On the waterproofing side, the website lists exterior excavation with membrane installation, weeping tile replacement, interior drainage channels, sump pump systems, window well leak repair, and crack repair with polyurethane injection or epoxy. Reviewers mostly describe the crack work. Curtis credits Myles for a crack injection repair, Kelly says Zack traced the source of a basement leak while explaining each step, and Janice names Brayden as the crew lead who stayed patient with her questions during a stressful repair. The company also does stucco, parging, concrete flatwork, asphalt and interior renovations, which helps when a dig-out leads to finishing work.

Above Grade Construction Services holds 4.9 from 140 Google reviews, read October 21, 2026. Most of the praise is about responsiveness, clean worksite habits, and prices that stayed at the quote. The review text we read contains no complaints. The site states that all work is guaranteed for materials and workmanship, but it does not publish the length of that guarantee or say whether it transfers to a buyer.

Alberta has no waterproofing-specific licence, so there is nothing to look up for that trade. Instead, confirm WCB Alberta clearance, the company's City of Edmonton business licence, and that any required Safety Codes permits will be pulled for the work. The company displays BBB accreditation, Small COR and Alberta Construction Safety Association badges, which you can check with those bodies.

This company suits Edmonton homeowners with foundation cracks or seepage who want a fast estimate and a founder who answers the phone. It suits large exterior excavation projects less well if you want a specialist who only does waterproofing. Before booking, ask for the guarantee in writing with its length, ask who will be on site, and ask whether the quote is for interior or exterior work.
