Material selection is a schedule activity, not just a design activity. Every major material that goes into a renovation has a lead time, and every lead time has a sequence dependency — something must happen before that material can be ordered, delivered, or installed. Getting selections wrong timing-wise is one of the most reliable ways to extend a kitchen or whole-home project by weeks without any change to the scope.
Here's the decision sequence for major materials in a West Metro remodel, and why the order matters.
What Must Lock Before Permit
Permit drawings require specific information about materials and locations. These selections must be made before permit submission — not after:
- Cabinet manufacturer and door style: cabinet dimensions define the permit drawings for kitchen layouts. The hood flue location, window sill heights, and countertop overhang are all drawn to cabinet dimensions.
- Window sizes and specifications: any window that's being added, moved, or changed in size must be confirmed before permit drawings are complete. Window dimensions drive structural header sizing.
- Appliance specifications: range size, refrigerator width, and dishwasher location are all drawn into the permit set because they affect rough-in locations for electrical and gas.
- Structural and foundation materials: if the project includes load-bearing modifications, foundation work, or structural framing, material specifications (beam sizing, concrete mix, foundation type) are in the permit documents.
What Must Lock Before Rough-In Closes
After permits are issued and rough framing is done, rough-in tradespeople are installing in-wall systems that depend on final material specifications. Missing these windows costs money to revisit:
- Tile and fixture selections for bathrooms: linear drain location, niche blocking, heated floor thermostat location, and valve body rough-in depth all depend on knowing the final tile thickness and fixture specifications.
- Lighting layout: recessed can spacing, switch leg locations, and specialty lighting circuits should be confirmed against a final furniture plan during rough electrical — not after drywall.
- Built-in locations: blocking for shelving, TV mounts, towel bars, and grab bars should be installed during framing. Blocking added after drywall requires patching.
- HVAC register locations: supply and return air register locations should be confirmed during rough-in framing. Adjusting these after drywall requires cutting and patching.
How Allowances Protect the Schedule
Allowances are the mechanism that lets a project move forward on schedule when a selection hasn't been finalized. They protect the schedule at the cost of some budget uncertainty:
- An allowance is a placeholder dollar amount in the contract for a category of selection not yet finalized. Work proceeds; the homeowner's final cost is adjusted up or down from the allowance when the selection is made.
- The risk of allowances is that they're often set optimistically. A $4,000 tile allowance for a primary bath may not be sufficient for the homeowner's actual material preference. Reviewing allowance levels against real material costs early avoids sticker shock at reconciliation.
- Allowances should have deadlines: the contract should specify when each allowance must be finalized to keep the schedule. An open allowance is a schedule risk — the contractor can't order or schedule installation without a final selection.
KCC builds material selection timelines into every project plan, with deadlines for each category tied to the construction sequence. Request a consultation to see how we structure selections so your project doesn't get delayed by late decisions.
