Most homeowners calling about a renovation have the same question: “How long is this going to take?” For a mid-size project — a main floor refresh, a kitchen redo, or a primary suite addition — the honest answer is usually around 12 weeks once we’re swinging hammers. But there’s another 4 to 8 weeks of planning before that first wall comes down, and skipping over it is the single biggest reason renovations go sideways.
Here’s what the home renovation Langley process actually looks like, week by week, with real numbers and the BC permit realities baked in.
Weeks -8 to -4: First Call, Site Visit, and Ballpark
The first call is short — maybe 15 minutes. We’re asking what you want done, when you’d like to start, and whether you’ve got a budget range in mind. If you don’t, that’s fine; we’ll give you ranges based on what we’re seeing in the Lower Mainland right now:
- Kitchen renovation (mid-range, full gut): $55,000–$95,000
- Main bathroom renovation: $25,000–$45,000
- Basement suite (legal secondary suite, 800–1,000 sq ft): $90,000–$160,000
- Whole-home interior refresh (2,000 sq ft): $150,000–$300,000+
These ranges shifted up about 15–20% post-2021 and haven’t really come back down. Labour and trades availability in Surrey and Langley are the main drivers.
After the site visit, you’ll get a written estimate within 7–10 days. If the numbers work, we move into a design and scope agreement.
Weeks -4 to 0: Design, Selections, and Permits
This is the phase homeowners underestimate. Cabinet lead times alone can run 6–10 weeks, and that clock needs to start ticking before demo, not after. During these weeks you’ll be:
- Finalizing drawings (and structural engineering if you’re moving walls)
- Choosing finishes — cabinets, counters, tile, plumbing fixtures, flooring, paint
- Signing off on the fixed-price contract
If your project needs a building permit — and most do, including kitchen layout changes, structural work, plumbing relocations, and any electrical service upgrade — we submit to the Township of Langley or City of Langley depending on where you sit. Current turnaround for residential permits is running 4–8 weeks, sometimes longer for complex projects. Heritage properties in Fort Langley or anything in the Agricultural Land Reserve add another layer.
For secondary suites, BC’s provincial regulations (updated under the housing legislation in 2024) made suites permissible across more zones, but you still need a permit, separate egress, fire separation, and parking compliance with the local bylaw.
If you’re at this stage and want to talk through what your specific project needs, send us the details of what you’re planning and we’ll walk you through the permit and timeline implications before you commit to anything.
Weeks 1–2: Demo and Rough-In Prep
Day one is protection — floor coverings, plastic walls, dust barriers, and HEPA filtration if you’re living in the house during the reno. Demo on a kitchen takes 2–4 days. Bathrooms, about 2 days. A whole main floor, closer to a week.
This is also when surprises show up: knob-and-tube wiring in older Langley homes, undersized plumbing stacks, rotted subfloor under the tub, or — in homes built before 1990 — asbestos in drywall mud or vinyl flooring. WorkSafeBC requires a hazmat survey before demo on pre-1990 homes, and any positive results mean abatement before we proceed. Budget $1,500–$5,000 as a contingency for this.
Weeks 3–5: Rough-In Trades
Framing changes, plumbing rough-in, electrical rough-in, HVAC adjustments, and any structural work happen now. Each trade comes through, gets inspected, and signs off before drywall. For permitted work, the municipal inspector visits at framing/rough-in stage — usually we book 48–72 hours ahead.
This is the messiest, slowest-looking phase. From the outside it feels like nothing’s happening, but this is where the bones of the renovation get set.
Weeks 6–7: Insulation, Drywall, and Paint Prep
Insulation inspection, then drywall — hung, taped, three coats of mud, sanded. A good drywall crew can do an average kitchen in 4–5 days. Primer goes on, and the room starts looking like a room again.
Weeks 8–10: Cabinets, Tile, Flooring
Cabinets get installed first, then countertop template (granite and quartz fabricators in the Lower Mainland need 7–14 days from template to install). Tile work — backsplashes, bathroom walls, shower pans — runs concurrently. Hardwood or LVP flooring goes down either before cabinets or after, depending on the design.
Week 11: Trim, Finish Plumbing, Finish Electrical
Baseboards, door casings, interior doors, plumbing fixtures, light fixtures, outlets and switches, appliance hookups. Final coat of paint. This week always feels like it should take three days and ends up taking seven, because finish work is where quality gets noticed.
Week 12: Final Inspections, Punch List, Walkthrough
Final municipal inspection for permitted work. We do our own punch list first — every door swing, every drawer pull, every caulk line — and fix anything before you see it. Then we walk through with you. Anything you flag, we fix within a week or two depending on whether it needs ordered parts.
You get your warranty documents, appliance manuals, paint codes for touch-ups, and a list of every trade who worked on the job in case something needs attention later.
Where Projects Actually Run Long
In our experience, the home renovation Langley timelines that blow out aren’t because of construction — they’re because of decisions. Tile picked late, cabinet hardware backordered, a homeowner changing the island size in week 4. The build phase is predictable. The decision phase is where you control your own timeline.
If you’re planning a renovation for spring or summer, the realistic window to start serious conversations is now — three to four months ahead. That’s not a sales pitch, that’s just how the permit and lead-time math works in the Lower Mainland.
