Phased & After-Hours Renovation Cost in DFW

Working nights costs more than working days, and any contractor who says otherwise is either absorbing it or planning to find it later. We put the multiplier in the scope as its own line so you can weigh it against what closing for a week would actually cost you.

What does a phased renovation cost in Dallas-Fort Worth?

Phased renovations have no published starting price: each one is scoped and priced per project after a site walk, lump sum from a written scope before any deposit, and the ranges on this page are for budgeting. The price includes labor, materials listed in the written scope, permits and standard city inspections, project management, mobilization, protection of adjacent areas, cleanup and one-year workmanship warranty. Scope, the condition of the space and the schedule move the number more than square footage does.

Paint and flooring refresh

$10 to $25/SF

Cosmetic update where the layout and the systems stay exactly where they are.

A layout change in a space that already works: some walls move, systems mostly stay.

Standard office TI

$65 to $95/SF

A full office fit-out: private offices, conference rooms, a break area, new finishes throughout.

Higher-end office TI

$95 to $140/SF

The same fit-out with a finish package and detailing that a client-facing floor needs.

All i30 Builders full-project prices include normal mobilization, ordinary protection of adjacent areas, labor, standard materials listed in the scope, permits and standard city inspections, project coordination, normal cleanup, and a one-year workmanship warranty on the listed scope.Every job in this category is custom, so these are budgeting standards rather than quotes. Landlord fees, FF&E, equipment, and specialty inspections are separate line items called out explicitly in the written scope.

What Drives the Final Number

Up and down, the honest answer.

Pushes price up

  • Night and weekend labour rates across every trade
  • Nightly cleanup, protection, and reset so you open in the morning
  • Dust and noise containment between the work and the occupied area
  • Working in smaller zones, which means more mobilizations
  • Landlord rules on freight elevator access and MEP shutdown windows
  • Inspections scheduled around the operating day rather than the build

Keeps price down

  • Closing for a short window instead of phasing the whole job
  • Phasing by floor or wing rather than room by room
  • A scope with no wet work or MEP shutdown to sequence around
  • Flexible operating hours that allow earlier evening starts
  • Consolidating noisy work into a single planned closure

Common Cost Questions

Phased renovation cost questions

How much more does after-hours work cost?

It carries a multiplier over the daytime rate, typically 1.2x to 1.4x on the labor portion, and it is stated as its own line in the scope rather than folded into the per-square-foot number. The base ranges still apply. What phasing adds is night and weekend labour, nightly protection and reset, and more mobilizations because the work happens in smaller zones.

Is it cheaper to just close for a week?

Sometimes, and we will tell you when. If your revenue for that week exceeds the phasing premium, closing is the rational choice and we will schedule it that way. The point of pricing the multiplier separately is that you can actually do that comparison instead of guessing.

Can you really hand the space back every morning?

That is the standard we work to. On a recent Mansfield medical office we rebuilt the front desk and check-in area entirely after hours, with nightly cleanup and reset, and the suite never closed a business day. In Rowlett we delivered a conference room build and full suite repaint in a three-day window inside an occupied office.

How do you keep dust out of the occupied area?

Containment partitions, negative air where the scope calls for it, protected routes for material in and debris out, and a nightly reset that includes the shared areas your customers walk through. In clinical settings that extends to infection-control containment.

Is the quoted price the final price?

Yes, written scope, locked at signing, phasing multiplier included as its own line. Change orders happen only if you request a scope change, and they are priced and approved in writing first.

What's included in the per-SF price?

All i30 Builders full-project prices include normal mobilization, ordinary protection of adjacent areas, labor, standard materials listed in the scope, permits and standard city inspections, project coordination, normal cleanup, and a one-year workmanship warranty on the listed scope.
