Etobicoke's 1950s and 1960s split-levels and bungalows near the Humber, plus its newer lakefront condos, demand a contractor who understands both ends of the spectrum.

Active leaks anywhere in the GTA get same-day priority dispatch. We answer at 2am, including weekends and holidays.
Complete liability coverage on every job. All work is documented and you are protected from start to finish.
Inspection reports, repair documentation, and scope estimates in writing before we touch anything.
We've worked on tens of thousands of GTA buildings. We recognise failure patterns before they become emergencies.
We trace the actual failure mode before proposing a scope, and we quote what that scope requires rather than inventing urgency.
“Etobicoke's building stock spans five decades and several distinct construction styles. We know the 1950s split-level as well as we know the lakefront mid-rise, and we apply the right approach to each.”

I emailed at 4 a.m. and spoke with someone that same day. Estimate and completed work all within one day. Pricing was fair, work was excellent.
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

We work across all areas of Etobicoke. If you don't see your neighbourhood listed, we almost certainly cover it.
Yes. We work on properties in the Humber Valley area regularly. Humber-adjacent properties often have specific drainage and moisture challenges we're familiar with.
Yes. We work on flat-roof commercial and industrial buildings throughout Etobicoke's industrial corridors.
Split-levels have complex rooflines with multiple flashing intersections. We assess all the critical points and give you a written diagnosis before proposing any work.
All of it, from Rexdale and Kingsview Village in the north down through Richview and Islington to Alderwood, Mimico, and New Toronto on the lake. Our shop sits just across the Humber in North York, so the northern half of Etobicoke is one of the shortest runs we make anywhere in the city.
Yes, through Toronto Building, which serves Etobicoke from the civic centre on Burnhamthorpe Road. Structural roof work and foundation alterations need a permit; a like-for-like reroof generally does not. Properties inside The Kingsway's heritage area carry additional review for exterior alterations, and we check that before quoting.
Yes, through our balcony repair and waterproofing service. Etobicoke has a large stock of 1960s and 70s apartment towers along Dixon Road, The West Mall, and the Kipling and Islington corridors, plus the newer lakefront condos at Humber Bay, and all of them have balcony slabs taking weather on every exposed face. Once the surface coating fails, water and de-icing salt reach the reinforcing, and the concrete cracks and spalls from the edges and railing pockets inward. Our process is to sound the concrete for hidden delamination, cut out and rebuild what has failed, and finish with a waterproof surface detailed at the drains and wall junctions. Scope and price come in writing first.
Etobicoke is bounded by water on two sides and cut through the middle by a third, and that shapes more of the work here than the housing eras do. Lake Ontario runs the whole southern edge past Alderwood, New Toronto, and Mimico. The Humber River forms the eastern boundary and carries a broad valley with a genuine flood plain through Humber Valley Village and The Kingsway. Mimico Creek runs a parallel course further west. Between and above them, Richview, Rexdale, and Kingsview Village sit on ordinary higher ground.
So the first thing worth establishing about an Etobicoke property is its relationship to water: how close, how low, and which of the three. Two houses built the same year to the same plan will not have the same problems if one is on the Humber flats and the other is up on Richview.
The work divides fairly predictably across the borough. Emergency roof repairs are the most time-critical share of it, and they cluster along the exposed lakefront where wind arriving off open water lifts and tears rather than gradually wears: ridge caps peeled back, drip edge unfastened along a rake, whole courses removed from a windward slope in a single event. Inland, the same storm produces fewer calls and different ones, mostly debris and blocked drainage.
Next is targeted repair on the 1950s and 60s split-levels through Richview and Markland Wood, where an Etobicoke roof of that era carries multiple planes meeting at different heights and the failures concentrate at those intersections rather than in the open field. Our roof repair services on these houses begin with tracing the water rather than pricing a slope, because on a complex roof system the point where a stain appears is frequently nowhere near the breach.
A smaller but growing share is full roof replacement, as the coverings installed across the borough in the late 1990s reach the end of a first cycle together. Where a roof genuinely has years left we say so, and Toronto homeowners who have been told otherwise by somebody working door to door after a storm are welcome to get that second opinion in writing.
Etobicoke residents often find that contractors from other parts of the city apply uniform approaches to buildings that warrant specific treatment. We don't do that. We read the building before we propose a scope of work.
Our written reports and estimates are honest, we don't inflate scope to pad invoices, and we don't minimise problems that need proper attention.
Etobicoke stretches from the Lake Ontario shoreline north through mature residential neighbourhoods to the 427 corridor. The housing stock reflects this range: pre-war heritage homes near Old Etobicoke Village, 1950s-60s split-levels in Richview and Markland Wood, and newer high-density development near the waterfront.
The Humber River valley introduces specific challenges for properties on its banks, high moisture, aggressive frost-heave, and proximity to mature tree canopy that accelerates shingle degradation and blocks drains. We work on these properties regularly and know what to look for.
Commercial Etobicoke, the industrial and big-box corridors along Islington and The Queensway, presents a different set of issues: large-span flat roofing systems on retail and light industrial buildings, many of which were installed in the 1990s and are now reaching end-of-life cycles.
Etobicoke's building stock spans five decades and several distinct construction styles. We know the 1950s split-level as well as we know the lakefront mid-rise, and we apply the right approach to each.
