Battery backup sump pumps act as your home’s second line of defence. When your main sump pump fails—whether due to a power outage, mechanical failure, or overwhelmed system—a battery-powered backup automatically kicks in. It quietly moves water out of your basement, even when the lights go out.
Here’s why it matters in Toronto:
Power failures often hit when storms do. Without backup, water quickly accumulates.
Water seeping through cracks in your basement walls or floors is a clear indication of a problem with your foundation.
Whether you’re at work, on vacation, or simply asleep—your home remains protected.
These systems are especially critical if your basement houses valuable items, finished living space, or home offices. For many homeowners in the GTA, a backup sump pump isn’t a luxury—it’s an essential safeguard.

Rob Fratric2025-05-31 Great job. Fast response to inquiries, job done fast and professionally. Put everything around the area back in place to the point where you wouldn't even know any work was done afterwards. Would 100% recommend calling them if you have a foundation repair issue. Luke Chiasson2025-04-18 Let's just say that there aren't many companies of this calibre around these days. We've been dealing with GJ MacRae for the last seven years for everything sump pump related. Seven years ago the fine folks at GJ MacRae came in and replaced our existing sump with a modern unit complete with a marine battery backup and secondary pump. We have a ton of ground water around here and when it rains our sump fires non stop. Everything has been perfect and when it came time to service our system seven years in, GJ MacRae was all over it. Exceptional service, communication price and product. It's rare to see all 3 these days. Thanks for everything Gavin. Jeff S2025-03-23 Gavin of GJ MacRae and his team did an amazing, quick and clean installation of a sump pump in our basement! I was very impressed with every aspect, from communication, to timing, to the finished product! Absolutely would recommend them! Thanks Gavin!

Peggy Smith2024-08-25 Very happy with a recent job completed by GJ MacRae Foundation Repair at our home. The service was excellent, the owner and working crew were very courteous and knowledgeable about their trade. They completed the work on time and on budget and they did a great job! I would highly recommend this company for any foundation/basement you may have. Brian Klodt2024-07-15 Used GJ MacRae for a foundation repair at our heritage house built circa 1894. The experience was positive from the quoting through 3 days execution of the work. Was done on time and on budget with a hard working crew who were experienced and left behind a strong and waterproof block wall. Gavin the owner was a pleasure to work with. Would use them again if ever needed. Lisa Kemp2024-07-15 G J MacRae installed a sump pump in my house to help with a water problem in my basement.

With AGM marine batteries, expect 3–5 years of reliable backup.
DIY is possible, but a professional installation ensures proper check‑valves, discharge routing, safe wiring, and code compliance.
Our approach includes backup alarms and routine maintenance, plus we offer combined systems to cover both power loss and pump malfunction.
Yes. While they require less maintenance than primary pumps, it’s important to test the system every few months, check battery charge levels, and replace the battery every 3 to 5 years to ensure reliable operation during emergencies.
If your home has experienced power outages during storms, or if your basement contains finished spaces or valuable items, a backup system is highly recommended. Even a reliable primary pump can fail due to power loss or clogging—having a battery backup offers essential protection.
