Pre-Renovation Diagnostic in Toronto GTA
RenoHouse offers FLIR pre-renovation thermal diagnostic scans for Toronto and GTA homeowners planning a kitchen, bathroom, basement, or whole-home renovation. A pre-renovation thermal scan happens BEFORE demolition begins โ it identifies hidden plumbing leaks, electrical hot spots, missing insulation, water damage, frozen-pipe risk, and other problems that would otherwise be discovered (expensively) once walls come open. The scan informs the renovation scope, prevents budget surprises, and often pays for itself many times over by catching issues early. <strong>Why this is the highest-ROI thermal service we offer.</strong> The single most expensive moment in any renovation is when demolition reveals an unexpected problem mid-job โ a leaking shower pan that has rotted the subfloor, a knob-and-tube circuit hidden behind drywall, missing insulation in the wall we just opened, an undersized water-supply line. By the time the discovery happens, half your demolition budget is spent and the contractor has to stop, re-quote, and add days/weeks to the schedule. A $395 pre-renovation thermal scan that finds these issues before demolition begins routinely saves $4,000โ$15,000 on the project. <strong>What we look for.</strong> Plumbing wet-walls (under sinks, behind toilets, in tub/shower assemblies) for leak indicators. Drain-stack penetrations through floors and walls. Electrical panel and circuit thermography (especially aluminum-wiring branch circuits). Hidden HVAC ducts and supply trunks routed through walls or above ceilings. Insulation continuity in exterior walls and ceilings. Frozen-pipe vulnerability in exterior-wall plumbing. Subfloor moisture under flooring. Roof-leak migration above ceiling. Air leaks at attic hatches and rim joists. <strong>Pricing.</strong> Pre-renovation thermal diagnostic scan: $395 (credited toward the renovation contract). Includes 60โ90 minutes on-site, FLIR thermal scan, moisture-meter readings, pencil-sketch of pipe/wire/HVAC behind walls (where detectable), and a written recommendations memo with scope-adjustment notes for the renovation quote. The $395 is fully credited if we do the renovation. <strong>Lead-to-renovation conversion.</strong> 60โ80% of pre-renovation thermal scans convert into the renovation contract โ by the time we've spent 90 minutes diagnosing the customer's walls, the trust-and-insight investment usually closes the deal. Customers regularly comment that they feel "informed instead of sold" after the scan. Average converted ticket: $25,000โ$80,000 (kitchen reno), $15,000โ$40,000 (bathroom), $50,000โ$150,000 (basement finish or whole-home). <strong>What we deliver.</strong> Branded PDF with thermal images (MSX overlay), moisture readings, pencil-sketch of detectable in-wall services, prioritized recommendations memo ("these issues should be addressed during the renovation," "these can be deferred," "these require specialist follow-up"), and a scope-adjustment annotation against the original renovation quote. Insurance-friendly format if any findings end up triggering a claim during demo. <strong>Honest scope.</strong> Pre-renovation thermal does NOT replace traditional structural / drainage / engineering review for major renovations. We do not perform sewer-line video inspection, structural framing assessment, asbestos sampling, or geotechnical soil testing. For major demolition or load-bearing wall removal we recommend a structural engineer (we coordinate referral). The scan is a thermal diagnostic supplement that catches what visual quoting misses.

Frequently Asked Questions About Pre-Renovation Diagnostic
$395 standalone, fully credited toward the renovation contract if RenoHouse does the renovation. Includes 60โ90 minutes on-site, FLIR thermal scan, moisture-meter readings, pencil-sketch of in-wall services where detectable, written recommendations memo, and scope-adjustment notes for the renovation quote.
Routinely 10โ40x. A $395 scan that catches a hidden plumbing leak, knob-and-tube circuit, missing insulation, or rotted subfloor BEFORE demolition typically saves $4,000โ$15,000 in mid-project budget surprises and schedule overruns. Most customers tell us it was the smartest $395 they spent on the entire project.
Strongly recommended. Kitchens have plumbing supply lines, drains, electrical (especially 240V range and dishwasher circuits), and exterior-wall components โ all of which can hide problems that surface during demo. Pre-renovation scan is even more critical for older Toronto kitchens (pre-1980) where aluminum wiring and undersized supply lines are common.
Where detectable. Active plumbing (hot or cold water flowing) shows up clearly; static water lines need short hot-water or thermal-loading runs to detect. Active electrical circuits under load show up; cold circuits don't. We sketch what we can see during the scan and clearly note what we cannot detect โ this is a useful pre-demo planning tool but NOT a substitute for as-built drawings or invasive opening.
Almost always. The savings come from three places: (1) avoiding mid-project surprise discoveries that trigger change orders and schedule overruns, (2) better-scoped initial quote (we know what's behind the walls before we quote), (3) better material orders (we order the right replacement insulation/wiring/plumbing for what's there, not what we guessed). Customers report 5โ15% lower total project cost with a pre-scan.
We document the finding, scope the additional work, and update the renovation quote BEFORE demolition begins. This is exactly the value of pre-renovation diagnostics โ pricing certainty before the saw comes out. Many findings (hidden leak, electrical hot spot, asbestos-suspect material) actually IMPROVE the customer's negotiation position with their insurance company or original contractor.
A traditional contractor walkthrough quotes based on what's visible โ finishes, fixtures, layout. A pre-renovation thermal scan adds non-destructive visibility into what's BEHIND those finishes โ hidden moisture, electrical, insulation, HVAC. Together they produce a much more accurate scope and quote than walkthrough alone.
Yes โ we'll happily do the diagnostic for a project you've contracted to another renovator. The $395 fee is not credited in that case (we don't get the renovation contract), but the value to you is the same. Many Toronto homeowners use our scan to validate or stress-test a competing contractor's quote.

โRenoHouse's thermal inspection caught a leaking shower pan before our bathroom demo. Saved us probably $5,000 in surprise demolition. Worth every penny of the $395.โ
