Professional sump pump installation & repair
Your sump pump is part of your home’s defence against unwanted water. Donaldson’s licensed plumbers can assess your existing system, troubleshoot problems and recommend the right repair, replacement or new installation for your home.
We’ll help you understand what your home needs without recommending more than necessary. We service all makes and models, including systems we didn’t install. Sump pumps are part of our plumbing services; if water is backing up through a floor drain, see drain cleaning, and for a leak elsewhere in the house, see plumbing repair. We serve homes in London and surrounding communities.
What to expect
Whether you’re dealing with an existing pump that isn’t working or planning a new installation, we’ll assess the setup first and explain what we recommend before the work begins.
Step one
Schedule service
Call us now, fill out the form, text us or schedule online, whatever’s easiest. Tell us what’s happening with your existing sump pump or what you’re looking to have installed, and we’ll arrange a convenient time to visit your home.
Step two
Assess system
Your plumber will inspect the existing sump pit, pump, float, discharge setup and other accessible components relevant to the problem. For a new installation, we’ll assess the home’s existing drainage setup and what’s required.
Step three
Review options
We’ll explain what we found and recommend the appropriate repair, replacement or installation. If backup protection makes sense for your home, we can discuss those options too.
Step four
Repair or install
Once you approve the work, we’ll complete the repair or installation and test the sump pump to make sure it’s operating properly. We’ll also walk you through anything you should know about the new or repaired system.
Basement flooding grant for London homes
The City of London’s Basement Flooding Grant Program provides financial assistance to qualifying homeowners for certain improvements designed to reduce the risk of basement flooding.
Current eligible work includes certain new sump pit and pump installations associated with weeping-tile disconnection, as well as qualifying battery backup systems installed with a new sump pump. The program does not provide funding for maintenance, repair or replacement of an existing sump pump.
Eligibility and funding are determined by the City of London, and homeowners must receive approval before starting eligible work.

What your neighbours are saying about us
Choosing the right sump pump for your home
Not every home needs the same sump pump setup. The right choice depends on your existing sump pit and drainage system, how much water the pump needs to manage and whether you want additional protection during a power outage.
Submersible sump pumps
A submersible sump pump sits inside the sump pit and operates below the water level when activated. This type of pump offers a compact setup and typically operates more quietly because the pump is contained within the basin.
Pedestal sump pumps
A pedestal sump pump keeps the motor above the sump pit while the pumping mechanism extends into the basin. The above-pit design makes the motor easier to access and can work well with certain sump pit configurations.
Battery backup sump pumps
A standard sump pump relies on your home’s electrical power. A battery backup provides a second line of protection that can continue moving water if the power goes out, which is particularly valuable when a heavy storm and power outage happen at the same time.
Proper sizing matters
The right sump pump also needs enough capacity to handle the amount of water entering the pit and move it effectively through the discharge system. Donaldson can assess your setup and recommend a pump that’s appropriate for your home’s needs.

Sump pump FAQs
Have more questions? We’ve got the answers.
A sump pit collects groundwater that reaches the drainage system around your foundation. As the water in the pit rises, the sump pump switches on and moves the water through a discharge line to a safe spot away from the basement. Once the water level drops, the pump shuts off. If yours isn’t cycling like this, book a sump pump check.
A sump pump may need attention if it won’t turn on, runs continuously, makes unusual noises, doesn’t remove water effectively or has become unreliable. Whether repair or replacement makes more sense depends on the pump’s condition and the cause. We service all makes and models, including systems we didn’t install, and explain your options with upfront pricing. Book a repair.
Check your sump pump before seasons when heavy rain or snowmelt adds water around your foundation, so problems with the pump, float or discharge show up before you need it. It also helps to keep gutters clear and point downspouts away from the house. If a floor drain is backing up instead, see drain cleaning.
A submersible pump operates inside the sump pit and tends to run more quietly, while a pedestal pump keeps its motor above the basin, where it’s easier to reach. Each suits different spaces and sump-pit setups. Donaldson can help you decide which makes sense for your home: talk to our plumbers.
Not every home needs one, but a battery backup keeps water moving if your primary pump can’t run during a power outage. It’s worth considering where the pump runs often during storms or where flooding would cause significant damage, and a qualifying backup installed with a new pump may be eligible for the City’s grant (see above). Ask about a battery backup.
The City’s Basement Flooding Grant Program may provide funding for qualifying new sump pit and pump installations associated with eligible flood-prevention work. Certain battery backup installations may also qualify. Repairs and replacements of existing sump pumps are not covered. Eligibility and approval are handled directly by the City of London, and work should not begin before City approval if you’re applying for funding.
The cost depends on whether you’re repairing or replacing an existing pump or installing a new sump system, the type and capacity of pump, the existing pit and discharge setup, and whether backup protection is added. Donaldson assesses what’s required and gives you upfront pricing before any work begins. See all our plumbing services.
