Interior finishes subcontracting for renovation projects requires a fundamentally different operational process than new construction, and a finishes sub who excels in new construction production does not automatically have the capabilities that renovation requires. The differences are structural: renovation happens in a constrained time window per unit, often with the building occupied, in a substrate environment that may have hidden conditions not present in new construction, with a countertop procurement strategy that must account for fabrication lead time within the access window.
GCs who run both renovation and new construction projects need to evaluate finishes subs specifically on their renovation capability, not assume that a strong new construction performance record transfers to renovation environments without verification.
The access window constraint
New construction interior finishes proceed at a building or floor level, sequenced over weeks and months as the construction schedule advances. Renovation interior finishes on occupied multifamily properties are constrained to the access window for each individual unit: the time between the previous tenant moving out and the next tenant moving in. In a typical value-add renovation, this window is seven to fourteen days.
Within that window, the finishes sub must complete demo, substrate preparation, cabinet installation, countertop delivery and installation, flooring installation, accessories, mirrors, and window treatments. Every day lost to a delay in any one of these steps reduces the time available for the steps that follow.
A new construction flooring sub who installs across full floors at a time with ample staging and no access constraint may not have the pace-management process to complete flooring in a single unit within a two-day window while simultaneously managing three to five other units at different stages of the renovation sequence.
Pre-templating as a renovation strategy
The countertop fabrication lead time, ten to fourteen days for most quartz products, is the most significant scheduling risk in value-add renovation. In new construction, template happens after cabinet installation and fabrication follows. In renovation, this sequence puts the countertop delivery ten to fourteen days after cabinet installation, which means the access window would need to be extended by that amount to complete the renovation within the window.
A renovation-capable finishes sub uses pre-templating: measuring the existing countertop dimensions before the unit is vacated and placing the fabrication order immediately so that the new countertop arrives concurrent with or immediately after new cabinet installation. This strategy requires the sub to have an accurate measurement process for existing countertops that can be done without demo, and it requires placing an order with final dimensions before demo confirms those dimensions.
Some renovation projects specify the same countertop dimensions as the existing countertops. Pre-templating works cleanly in this case. Projects where the renovation changes the cabinet configuration, requiring different countertop dimensions, require a modified approach: pre-template the existing layout, pre-order standard components, and customize the final template immediately after cabinet installation.
Substrate conditions in renovation projects
Renovation substrates are unpredictable in ways that new construction substrates are not. An existing concrete slab in a 1990s multifamily building may have been repaired multiple times, may have adhesive residue from previous flooring installations, and may have moisture conditions that have changed over the building’s life. An existing wood subfloor may have squeaks, loose fasteners, and subfloor sections that need replacement before new flooring can be installed.
The renovation flooring sub must inspect each unit’s substrate at the start of the renovation sequence and identify any substrate conditions that need to be addressed before flooring installation. A new construction sub who is accustomed to specifying substrates that have been built to a known standard may not have the substrate assessment process to identify and price renovation substrate remediation upfront.
Require the renovation finishes sub to include a substrate assessment step in their unit-level renovation sequence and to identify any remediation scope before the renovation proceeds, not after the flooring crew arrives and discovers conditions that halt the installation.
Occupied building protocols
Renovation in an occupied multifamily property requires protocols that new construction does not: access coordination with the property manager and residents, noise-hour compliance with local ordinances, dust and chemical containment in a residential environment where adjacent units are occupied, and daily cleanup to restore the renovation unit and surrounding corridor to a condition that does not disturb residents.
A new construction finishes sub who has not worked in occupied buildings may not have these protocols developed. Ask renovation finishes subs specifically: what is your process for noise-hour compliance, how do you contain dust during demo and flooring installation in an occupied building, and how do you communicate access requests to the property management office?
How Innergy approaches renovation and new construction
Innergy covers interior finishes for both renovation and new construction multifamily projects across all seven divisions. Our renovation process includes pre-templating strategy, unit-level substrate assessment, noise-hour compliance protocols specific to local ordinances in each market, and access coordination with property management. For renovation or new construction interior finishes in TX, WA, OR, CO, UT, or NM, contact us and we respond within one business day.
Pricing differences between renovation and new construction
Interior finishes pricing on renovation projects is typically higher per unit than on comparable new construction scope because renovation carries costs that new construction does not: demo, debris haul, substrate remediation, access window management overhead, and the inefficiency of working in constrained existing spaces rather than open new construction.
GCs should request renovation-specific pricing from finishes subs rather than applying a new construction unit price to a renovation scope. A finishes sub who prices renovation at the same per-unit rate as new construction has either not accounted for the renovation-specific costs or is bidding low with the intention of covering the difference through change orders. Both outcomes create problems.
Confirm that the renovation bid explicitly addresses demo scope, debris management, substrate remediation allowances, and access coordination overhead. For renovation and new construction interior finishes in TX, WA, OR, CO, UT, or NM, contact us and we respond within one business day.
