Basement Waterproofing Rebates In Ottawa in 2026

In 2026, homeowners in Ottawa can take advantage of the city’s Residential Protective Plumbing Program (RPPP) to significantly offset the costs of basement waterproofing and flood prevention. As extreme weather and heavy rainfall become more frequent, this municipal initiative provides vital financial assistance to help you protect your property against devastating sewer backups and groundwater flooding.

Available Rebates & Savings in Ottawa

The RPPP offers substantial subsidies for specific structural upgrades and protective plumbing installations. Depending on your home’s needs, you may be eligible for:

Sump Pump Installation (New Pit): Up to $3,000 for the construction of a new sump pit and the installation of a primary sump pump equipped with a battery backup system.
Sump Pump Upgrade (Existing Pit): Up to $1,500 for installing a new primary or secondary sump pump with battery backup power into an existing pit.
Backwater Valve Installation: Up to $1,000 for an indoor sanitary or storm backwater valve, and up to $2,500 for an exterior storm backwater valve. These devices act as a physical barrier to stop city sewage from flowing backward into your basement.
Building Permits: The City of Ottawa will rebate 100% of the cost of the required building permits for these plumbing upgrades.

How We at Aquatech Help You Secure Your Ottawa Rebate

Applying for municipal grants involves strict age-of-home eligibility (e.g., pre-2012 for sanitary valves, pre-2004 for storm valves), inspections, and precise paperwork. We at Aquatech are dedicated to managing this complex process so you can secure maximum funding with zero stress.

Eligibility & Site Assessment: We provide a free initial diagnostic to determine exactly which structural upgrades your home needs and verify your property’s eligibility under the RPPP guidelines.
Permit Management & Code Compliance: Securing these rebates strictly requires a Building Permit. Our licensed specialists secure the permits for you and ensure every installation strictly adheres to the Ontario Building Code and City of Ottawa standards.
Flawless Documentation: To claim your funds, Ottawa requires a copy of the Building Code Services inspection report and a clearly itemized invoice indicating “paid in full.” We provide all the exact technical documentation required to guarantee your rebate is approved without delay.
Permanent, Warrantied Protection: Beyond the rebate, we at Aquatech secure your long-term investment by backing our structural drainage solutions with an industry-leading 25-year transferable lifetime warranty.

I used Aquatech to install a sump pump and do some interior basement water proofing one year ago. When I needed another pump installed, I have called Aquatech again. Crew of two - foreman and another worker arrived promptly, within a week, in time as promised. All work was done promptly and with high degree of quality. Crew was friendly and very diligent. Sump pump performes beautifully and everything was clean and tidy.

I had some increasing leaks in my basement this last rainy season. I got a very reasonable quote from Aquatech as there were about 17ft of area that needed to be addressed. Bob and Vlad arrived bright an early and got to work, they protected all areas of my backyard (gazebo and bbq etc) and got to work. Everything was cleaned up and put back and gravel laid back with my steps and stones leveled back. All repairs completed, and I'm very impressed and would gladly recommend them for your waterproofing needs. Thanks guys !!

I highly recommend AquaTech Waterproofing!! They do excellent work! It was a pleasure dealing with the company, right from obtaining the quote from Shawn, to the team doing the work. Shawn listened to all of my concerns about water leakage, offered solutions, & quoted a very fair price to resolve the problem. The men doing the repairs (Eugene and Michael) were very polite to deal with, hardworking, & left everything looking good & very tidy, as mentioned on the company website.

AquaTech was referred to me by my sister. She had need of their services 2 years ago & had experienced the same quality workmanship & customer service I received.

The repairs Aquatech made will give me peace of mind that I won't be experiencing flooding in my basement any longer!

I recently had Aquatech Waterproofing come by to assess a flooding issue in my basement, and I was truly impressed by their honesty and professionalism.

Shawn, the technician who came to my home, could have easily given me an expensive quote to re-dig and reinstall the drain and window well. Instead, he gave me an honest and straightforward diagnosis — explaining that the real issue was grading around my home. He told me that with proper water management and redirecting the downspouts, the flooding problem would resolve itself.

That level of integrity and expertise is rare and admirable. Because of this experience, I would trust Aquatech completely for any waterproofing work in the future. If you’re looking for a company that values honesty, customer trust, and real solutions over just making a sale, Aquatech is the one.

We live in an older house and our basement started to leak every time it rained. We were worried about mold build up on the drywall and how it would impact the foundation, so we reached out to a few companies for quotes. Aquatech was friendly, had great reviews, and gave us the best price! They were professional, worked quickly, and were able to complete the entire sump pump installation and waterproof our entire basement in 1 day. I would highly recommend this company to anyone looking to waterproof their basement!

After a leak in our basement we found that we had 7 cracks in our poured foundation, several of which had started leaking. Shawn came out promptly to assess the situation and the work that was needed. He provided a quote quickly. Once we were ready to go ahead with the work, he was able to have a team start reasonably fast. The guys worked long - sometimes nearly 12 hour days. It took 7 days to have the house completely waterproofed on all three sides and completely replaced the drainage at the footing and the window wells. The guys were courteous and friendly, cleaned up after themselves and didn’t disturb our neighbours. Should we find ourselves in a home requiring waterproofing again, I wouldn’t hesitate to reach out to Aquatech again. Thank you!

I recently used Aquatech to do interior waterproofing of our basement. I could not be happier with their service. The sales process was very professional with a no-pressure approach and the salesman, Eugene, worked with me to fit within our budget. He was extremely responsive to questions as well. The construction crew, led by Slava, were very professional and polite. They made a mess and it was bad since it had rained very hard on them while they worked. They did not complain and cleaned up my basement so it was spotless - I didn't have to tell them to do this! Their work was very good and could not be happier! I highly recommend using Aquatech.

Terry is very knowledgeable and provides all options with full and detailed explanation. I even asked for drawings (as I’m very visual) and he enthusiastically did it for me. You feel confident he is looking after your best interest. He also explained how I can do some additional things myself to improve water drainage on the outside and save money. The work was fairly prized and professionally done. Alex and Yevhen were friendly and worked fast, clean and efficiently.

Waterproofed! Took a bit to get a date sorted because of how busy they were, but got a date within 3 weeks of our consultation. Luckily we weren’t in an emergency type of rush. Great price and even better work!

Absolutely thrilled with the job these guys completed on our 74 year old home in Hamilton! It was a HUGE undertaking and they did it in 3 days! These men work very hard and leave the place spotless until they come back the next day! Some evenings they were here until 9 pm! They were polite, respectful and extremely neat!!! Our sales rep Richard was very professional and extremely knowledgeable in the field! He listened and executed the work we asked for! We highly recommend them and their final price was fair and reasonable for the thorough job they did! We welcome a dry basement finally! Now we can start planing for those renovations and a new cosy basement for grandchildren!!!! Thank you for the great job!!!

Had the basement done from the inside, with the few recent heavy rain storms combined with a damp ground. Everything worked well, the sump pump kicked in and dispersed the water out of the house as planned and designed.
The pump isn’t loud, they also completed the city of Toronto sump pump rebate for me.
When the crew was here I requested a longer discharged pipe outside from the house and they accommodated with no problems.
The pricing was slightly better than the other 3 quotes I received.
Terry did an excellent job communicating and answering any concerns I had after the job was completed.

To those two guys who worked at my house. Kudos to you guys for working so hard in such cold temperatures. Greatly appreciated it 🙏

Hopefully it resolved all my water issues. Highly recommended .

Aquatech was wonderful right from the first contact to having Richard come out and give us a very complete and detailed quote to the two man crew who were here exactly on time and completed the day hours ahead of time. All the locates were taken care of and within a week of contacting them the job was completed. The workman did a fabulous job and were very respectful of our property. They reviewed the scope of the work before they started and asked if we had any questions. When the work was complete it was difficult to see where they had worked and dug the trench. Everything was tidier than before they started. We are very impressed and in a world where household repair companies can be less than favourable, Aquatech stands head and shoulders above any of them. We would highly recommend this company. We also have a life time transferable warranty too. Bravo. We will definitely be telling all the people we know about our wonderful experience. Thank you.

We had a flood disaster the day after we got the keys for our new home. Aquatech Waterproofing responded to my request for help quickly and came to access the damages the same day. They gave us several options for repairs as well as prevention that were fairly priced and a quick turnaround time. They executed our chosen plan quickly and did a beautiful job. They have been very responsive, answering questions about the products we chose and we recommend them to anyone that needs quality work done in a timely manner. Very compassionate and empathetic for our situation as well.

AquaTech is very professional and reliable. Valentina was very friendly, she scheduled the appointment at a convenient time and Nico came out to look at my problem. He diagnosed it and gave me a reasonable price. We went ahead with the job. The crew that came out to do it was very knowledgeable and professional. I had some questions and Igor explained everything to me with no problem. I highly recommend this company. Thank you AquaTech!

EXCELLENT experience. Andrew was the first one to arrive and was extremely kind and helpful. Igor and Basil joined Andrew a few minutes later and all three of them worked very hard and finished this massive job in one day. These are some of the hardest workers I have ever seen. There were no hassles or surprises and Andrew, Igor and Basil were very skilled and courteous. Also, Nico was VERY flexible with our constant changes of plans and was very accommodating and understanding. An excellent experience all around - could not recommend more highly!

Much thanks & appreciation to Slava & his hardworking crew for their excellent job excavating, installing weeping tiles & pipe, repairing cracks, waterproofing, and backfilling the 7'-deep trench 27' along the full side of our home. Wow!! On site, Slava, the lead foreman, clearly explained step by step their work including repairing foundation cracks and securing our downspout and other connections better then before. All in all, we are greatly satisfied & highly recommend Aquatech to anyone looking into correcting their leaking basements. Slava -- you & your crew brought humor, sincerity & experience -- no rush job here, just highly competent work by deserving technicians & company. Thanks also to Andrew and Terry for their super fast service with the gas line locate, the fast return calls, home inspection & estimate. Priced fairly for super work + 25 years warranty that can be passed on to a new homeowner. You guys were great!! Highly recommend! -- Anne & Frank - Scarborough

The Glebe, Centretown, and Old Ottawa South: We specialize in the structural preservation of historic stone and masonry foundations, utilizing advanced interior drainage and specialized moisture barriers to seal older, porous basements permanently.
Kanata and Stittsville: Our teams focus on robust exterior waterproofing and high-capacity sump pump installations to protect modern suburban developments from heavy surface runoff.

Frequently Asked Questions

What are the main signs my basement in Ottawa needs waterproofing?

The most common signs that your Ottawa home requires professional waterproofing include a persistent musty odor, visible pooling water after heavy rain or snowmelt, and damp, dark spots on your concrete walls. You should also look out for peeling paint, rusted appliances, or a white, powdery substance on the concrete. Because Ottawa experiences intense freeze-thaw cycles and shifting Leda clay, these symptoms indicate that hydrostatic pressure is forcing moisture through your foundation, requiring immediate assessment by our Aquatech specialists.

What types of basement waterproofing do you offer in Ottawa?

We at Aquatech offer a full spectrum of permanent, warranty-backed solutions tailored to Ottawa’s specific soil conditions:

Interior Waterproofing: Installation of internal weeping tile systems, drainage boards, and high-capacity sump pumps to safely manage water without digging up your yard.
Exterior Waterproofing: Full foundation excavation down to the footing to apply a multi-layered elastomeric membrane and dimple board, stopping water before it touches your home.
Foundation Crack Repair: Advanced, high-pressure polyurethane and epoxy resin injections to permanently seal structural fissures.

Will basement waterproofing increase the value of my home in Ottawa?

Yes, significantly. A wet basement is one of the biggest red flags for prospective home buyers and can drastically lower property value. By choosing us at Aquatech, you permanently eliminate moisture issues, expand your home’s healthy, livable square footage, and protect the structural integrity of the house. Furthermore, our 25-year fully transferable lifetime warranty acts as a powerful selling feature, giving future buyers absolute peace of mind.

I need an urgent quote for foundation repair in Ottawa. Who can I contact now?

You can contact our local dispatch team at Aquatech right now. We understand that a compromised foundation or active flooding is an emergency. We provide rapid-response, completely free, and transparent on-site quotes for urgent foundation repair in Ottawa. Our certified technicians will quickly arrive to assess the structural damage and provide a permanent, code-compliant action plan.

My basement is wet after it rains. Can you fix this?

Yes, we at Aquatech permanently fix this issue. A basement that floods after rainfall is suffering from intense hydrostatic pressure—meaning the soil around your home is saturated, pushing groundwater through failing weeping tiles or foundation cracks. Our experts will accurately diagnose the exact point of entry and install a robust internal drainage system or exterior membrane to redirect the water permanently, backing the work with our 25-year lifetime guarantee.

What causes white powder to appear on basement walls?

That white, chalky powder is called efflorescence. It is a primary indicator of moisture infiltration. When groundwater seeps through your porous concrete block or poured foundation walls, it carries natural salts and minerals with it. As the water reaches the interior of your basement and evaporates, it leaves those crystalline salt deposits behind. We at Aquatech eliminate efflorescence by sealing the walls and stopping the moisture intrusion at its source.

What is a sump pump and when do I need one?

A sump pump is an active mechanical device installed in a specially excavated pit in your basement floor. It works continuously to collect accumulating groundwater from your weeping tile system and safely pumps it outside, away from your foundation. You need a sump pump if your Ottawa home has a high water table, a history of flooding, or if you are having an interior waterproofing system installed. We also strongly recommend adding a battery backup to ensure protection during power outages.

How much does basement waterproofing typically cost in Ottawa?

We at Aquatech provide highly transparent, competitive pricing tailored to the scope of your project:

Interior Waterproofing: Typically ranges from $69 to $190 per linear foot.
Exterior Waterproofing: Typically ranges from $90 to $280 per linear foot, depending on the excavation depth required.
Crack Repair: Isolated foundation crack injections average between $400 and $800 per crack. We strictly offer a price match guarantee, ensuring you receive Ottawa’s most cost-effective, permanent solution.
