Selective Demo for Renovation Prep in London, ON — A Complete Guide
Selective demolition is the art of removing exactly what needs to go while preserving everything that stays. Unlike full demolition, selective demo requires precision, planning, and experience — especially in London, Ontario's older homes where hidden surprises lurk behind every wall. Whether you're prepping for a kitchen renovation, opening up a floor plan, or stripping a basement to the studs, understanding selective demolition helps you plan your project, budget accurately, and avoid costly mistakes.
What Is Selective Demolition?
Selective demolition — sometimes called surgical demolition or strip-out — involves carefully removing specific building components while keeping the surrounding structure intact. Common selective demo projects in London include:
Kitchen strip-out: Removing cabinets, countertops, flooring, backsplash, and sometimes walls to prepare for a kitchen renovation. Plumbing and electrical are capped, not removed.
Bathroom gut: Removing fixtures (tub, toilet, vanity), tile, drywall, and flooring down to the studs and subfloor.
Basement strip: Removing old finishes (panelling, carpet, ceiling tiles, drywall) to prepare for a modern basement finishing project.
Wall removal: Taking out non-load-bearing walls to create an open-concept layout. Load-bearing wall removal requires temporary support and a permanent beam — this is structural work that needs engineering.
Flooring removal: Stripping old carpet, tile, hardwood, or vinyl to prepare for new flooring installation.
Exterior selective demo: Removing a deck, porch, or section of siding while preserving the rest of the structure.
The key difference from full demolition: selective demo preserves what you want to keep — adjacent rooms, finishes, structural elements, and utilities that will be reused.
Selective Demo Costs in London (2025)
Kitchen strip-out (cabinets, counters, flooring, backsplash): $1,500–$4,000. Add $1,000–$3,000 if walls are being removed.
Bathroom gut (fixtures, tile, drywall): $800–$2,500 per bathroom.
Basement strip (full basement, old finishes): $2,000–$5,000. More if asbestos tile or materials are present.
Wall removal (non-load-bearing): $500–$1,500 per wall including patching adjacent surfaces.
Wall removal (load-bearing): $2,000–$8,000 including temporary support, permanent beam, engineering, and finishing.
Flooring removal: $1–$3 per square foot. Tile on concrete is the most expensive to remove; carpet is the cheapest.
Deck or porch removal: $500–$3,000 depending on size.
All prices include debris removal and disposal. At Sodify, we include bin rental and dump fees in our selective demo quotes — the price we quote is the price you pay.
Hidden cost warning: Older London homes (pre-1990) may contain asbestos in floor tiles, pipe insulation, or ceiling texture, and lead in paint. Testing before demo is essential ($200–$500). If hazardous materials are found, professional abatement is required before demo can proceed.
The Selective Demo Process
At Sodify, our selective demolition process protects your home and sets up the renovation for success:
1. Scope walkthrough: We walk through the project with you, marking exactly what gets removed and what stays. We photograph existing conditions for reference.
2. Utility protection: We identify and protect utilities that run through the demo area — electrical wires, plumbing pipes, gas lines, and HVAC ducts. Utilities being removed are properly capped and disconnected.
3. Protection setup: Adjacent rooms and surfaces are protected with plastic sheeting, floor protection, and dust barriers. We seal doorways and HVAC vents to prevent dust from spreading through your home.
4. Demolition: Working methodically from top to bottom, we remove the specified materials. We use hand tools near sensitive areas and power tools where appropriate. Load-bearing elements are never touched without engineering approval and temporary support in place.
5. Sorting and disposal: Materials are sorted — recyclable items (metal, clean wood, concrete) are separated from landfill waste. We haul everything away, leaving you with a clean, prepped space.
6. Inspection: We walk through the stripped space with you, noting any hidden issues discovered during demo (water damage, mould, outdated wiring, structural concerns) so they can be addressed before the renovation begins.
Timeline: Most selective demo projects take 1–3 days. A full kitchen strip-out takes 1–2 days. A basement strip takes 2–3 days.
Frequently Asked Questions
Q: Can I do selective demo myself to save money? A: Some tasks are DIY-friendly — removing carpet, pulling out cabinets, and stripping wallpaper. However, anything involving utilities (electrical, plumbing, gas), potential hazardous materials (asbestos, lead), or structural elements should be left to professionals. The savings from DIY demo are often offset by the time it takes and the risk of damaging things you wanted to keep.
Q: How do I know if a wall is load-bearing? A: General rules: walls running perpendicular to floor joists are often load-bearing; walls running parallel are often not. But this isn't always reliable. The only safe way to know is to have a professional assess the structure. At Sodify, we check every wall before removal.
Q: What should I do with salvageable materials? A: Hardwood flooring, solid wood doors, vintage hardware, and brick can often be salvaged and reused or donated. Habitat for Humanity ReStore in London accepts many building materials. We can carefully remove items you want to save.
Q: How messy is selective demolition? A: It's dusty and noisy, but professional crews minimize the mess. Our dust containment setup (plastic barriers, sealed vents, floor protection) keeps the rest of your home clean. We clean up thoroughly at the end of each day.
Q: Should I do demo before or after getting renovation quotes? A: Get renovation quotes first. Your contractor needs to see the existing conditions to provide an accurate quote. Demo reveals hidden conditions that may change the renovation scope and cost. At Sodify, we handle both demo and renovation, so the process is seamless.
Selective demolition is where every renovation begins. Done right, it sets the stage for a smooth, successful project. Done wrong, it creates problems that haunt the entire renovation.
