Selecting Materials and Finishes Before Construction Begins

Preconstruction Services — The single most consistent driver of renovation budget overruns is deferred material selection — decisions about tile, countertops, fixtures, hardware, flooring, and cabinetry that are not made during preconstruction but are instead deferred to "after we start" or "when we get to that part." Every deferred selection is an allowance in the contract. Every allowance that turns out to cost more than the allowance amount is a change order. Completing material selections in the design phase is the most direct budget protection action available to a renovation owner.

Material Selection Priorities by Phase

• Before design is complete: cabinet style and wood species, countertop material category, tile direction
• Before permit submission: window and door schedule (sizes affect rough openings in structural drawings)
• Before demolition begins: all tile (needs to be ordered; lead times vary), all fixtures, all appliances
• Before rough-in: exact fixture models (determine rough-in dimensions for plumbing), appliance selections
• Before cabinet installation: countertop material and supplier confirmed (templating follows cabinet install)
• Can extend to construction: paint colors, hardware, lighting fixtures (do not affect sequence)

Why Material Lead Times Matter More Than You Think

The construction sequence waits for materials. Cabinet installation waits for cabinetry to be produced. Countertop templating waits for cabinet installation. Tile installation waits for tile to arrive. If tile with an 8-week lead time is ordered when demolition begins rather than when the design is approved, and the tile installation sequence is 6 weeks into construction, the renovation pauses for 2 weeks waiting for tile that was ordered too late.

Lead times by category in 2025: in-stock domestic tile (same-week availability), custom or imported tile (4–12 weeks), countertop slabs (stone — 2–4 weeks for fabrication after template; template is 2–3 weeks after cabinet installation), custom cabinetry from Timber's Millwork Division (4–6 weeks from approved drawings), semi-custom cabinetry from manufacturers (6–12 weeks), custom windows (8–16 weeks from approved shop drawings), lighting fixtures from domestic suppliers (1–4 weeks), specialty or imported lighting (6–12 weeks).

The critical path items — the selections whose lead times most affect the construction schedule — are custom cabinetry and custom windows. Both should be ordered immediately after their selections are approved in the design phase, not deferred until construction is underway.

The Allowance Trap

Allowances in a construction contract are budget placeholders for items not yet selected. The contractor inserts an allowance number that represents their best estimate of what the item will cost — usually based on a mid-range assumption. The allowance number is not a guarantee; it is an estimate that will be replaced by the actual cost when the selection is made.

The problem: allowance numbers are frequently set conservatively low to keep the initial contract total down. The homeowner receives a contract with an $8/sq ft tile allowance, buys tile at $22/sq ft, and receives a change order for the difference on 400 square feet of tile — a $5,600 change order that was predictable from the moment the low allowance was set.

Timber sets allowance numbers at the actual specification level described by the client during the design consultation. If a client describes a high-end tile installation, the allowance reflects high-end tile pricing — which produces a contract that is more likely to represent the actual final cost.

The Selection Schedule

A selection schedule is a document that lists every material selection required by the project and the date by which each selection must be made to avoid affecting the construction schedule. Timber provides a selection schedule at the start of every renovation project so that clients know exactly when each decision is needed — and can plan their time accordingly.

The selection schedule also identifies selections that have external dependencies — selections that require a visit to a stone yard, a trip to a tile showroom, or a consultation with a hardware supplier that takes more time to complete than a simple online selection. Planning for these visits in advance prevents the selection from becoming a schedule constraint at the last minute.

Fun fact: The most common single cause of kitchen renovation schedule extension (beyond the critical path) is countertop delay — which is invariably caused by a late countertop material decision rather than a fabrication problem. Countertop material must be selected before cabinet installation begins (because the edge profile, thickness, and overhang dimensions affect the cabinet top design), and confirmed with the stone yard visit before fabrication begins.

Frequently Asked Questions

What happens if we change a material selection after construction begins?

Material changes after construction begins vary in complexity and cost. Changing a paint color after walls are painted: minor cost, straightforward execution. Changing tile after tile has been ordered but not installed: cost depends on whether the ordered tile can be returned and the lead time of the replacement tile. Changing countertop material after countertops have been fabricated: typically a full replacement cost — the fabricated stone cannot be returned. Changes earlier in the sequence are cheaper; changes after fabrication or installation are expensive to impossible.

Do we need to visit a stone yard to select countertops?

For natural stone (quartzite, marble, soapstone), yes — Timber recommends visiting the stone yard to personally select the specific slab. Natural stone varies significantly slab to slab within the same product name. The slab you select from a catalog image may not match what you receive. For engineered quartz, catalog selection is more reliable because engineered products have consistent appearance across production runs. Timber accompanies clients to stone yards for natural stone selections as part of the design process.

Can selections be delegated to the contractor?

For some categories, yes — standard items where the contractor's judgment and your stated direction are sufficient (grout color for a standard tile installation, standard hardware for cabinet installation, standard trim profiles). For high-visibility, high-cost items — tile, countertops, cabinetry finish, plumbing fixtures — owner review and approval of the specific selection before it is ordered is standard practice and protects both parties.
