Basement Underpinning Contractors in West Toronto

Basement Underpinning Services West Toronto Homeowners Rely On

We lower your basement floor to create real ceiling height and usable living space, with our own engineers and permit team managing the structural work start to finish.

Turn a Cramped Basement Into Real Living Space

A low, dark basement is one of the most common frustrations in West Toronto’s older homes. Underpinning lowers the foundation itself rather than just digging out the floor, which gives you genuine ceiling height for a family room, a rental suite, or extra bedrooms. We have handled this structural work across West Toronto for over two decades, and you can see examples in our portfolio.

Underpinning Is Serious Structural Work. Here Is Why the Contractor Matters

Basement underpinning involves temporarily supporting your home’s foundation while it is lowered, so this is not a project to hand to just anyone. Here is what can go wrong with the wrong team, and how we handle it instead.

What Can Go Wrong

How We Do It Right

One of the Highest-Value Renovations You Can Make

Underpinning adds genuine square footage without expanding your home’s footprint, which is why it is often paired with a full home renovation or used to create a legal rental suite for extra income. Curious what it actually costs? We have broken it down in detail in this cost guide.

Emmett was wonderful to work and I knew I could trust him with my project from our very first conversation. He managed our home renovation that included a custom kitchen where we had to take out a chimney and put in a structural beam. We added heated floors to our entryway and mudroom, installed new hardwood floors throughout, renovated two bathrooms and lowered the basement bathroom floor. The results were beyond my expectations and I would work with Emmett again in a heartbeat.

Emmett and his team helped my wife and I with the timely renovation of our third bedroom in time for the arrival of our first child. They also replaced three bedroom doors, installed a new bannister in our main stairwell, and painted. Throughout the project, I found Emmett and his team to be highly responsive and attuned to our needs, always going the extra mile to ensure that we were happy. We were able to move quickly and trust them to make decisions when we wished to step back, but were also encouraged to provide input and guidance every step of the way. This project was particularly challenging because we were living onsite during the renovation, and I felt that they made every effort to keep the space as tidy as possible for us. Ashford Homes uses a project management software called CoConstruct that makes communicating with their team easy and efficient. We always felt like we were a priority when communicating with Paul, our project manager, and were able to advise and provide input at various crucial stages of the project. The team was particularly receptive to the various minor tweaks that came up as we neared completion of the project, which is a big plus. My wife and I are very pleased with the result of our renovation. I highly recommend Emmett and his team to anyone.

Emmett worked with us on a 3 floor renovation of our older High Park home and we couldn't be happier. We had 2 structural walls removed, main floor kitchen completely demo'd and rebuilt, bedrooms modified on the 2nd floor and the entire 3rd floor gutted and rebuilt, including adding a 3 piece bathroom. His workflow made tracking progress easy, and he followed through with us whenever there was an issue that required a change in plans. His trades were reliable and professional, and the finishing touches have withstood years of abuse with no issues! I have a porch reno planned for this spring and will be meeting Emmett on Sunday to plan how we are going to get it done. Never considered calling anyone else.

We worked with Ashford homes to renovate a large three unit rental property. It was a century home, and they helped us bring it into the modern era while still keeping some of the beautiful features. They added 3 insuite laundries, 3 kitchen overhauls, 3 bathroom renovations. Additionally they did flooring, painting, new HVAC, asbestos abatement, in-ground plumbing and some electrical. The place looks great, and the tenants love it! Emmett and his crew were easy to work with; they always communicated issues pro-actively and gave options, and also use a software to track the schedule and the communications. Emmett has a solid sense of fairness and accountability, we appreciated his honest and transparent style. We will definitely work with them again in the future!

I've worked with Ashford Homes for over 13 years for several large and small renovations. They have always completed their work for me on time and on budget. Emmett and his crew are very responsive and a pleasurer to work with. They turned a house with offices and an awkward layout into a lovely single family home.
