Commercial Drywall Installation in Davenport, IA — Commercial Drywall Contractors for Office, Retail & Medical
Commercial interiors boarded across Davenport and the Quad Cities to the requirements a house never carries: fire-rated assemblies, sound ratings between tenant spaces, and a finish schedule written by an architect.
Commercial Drywall Installation in Davenport, IA
Davenport Elite Drywall is your local resource for commercial drywall installation throughout Davenport and the Quad Cities. We work with experienced commercial drywall professionals who build to listed assemblies and to a general contractor's schedule.
Commercial drywall differs from residential work in what the wall has to do rather than in how board is hung. A partition in an office building may need to resist fire for a specified period, limit sound transmission between tenants, carry the weight of millwork or wall-mounted equipment, and reach a finish level named in the project documents. Each of those is a requirement with a source — a code section, a listed assembly, a specification — rather than a judgment made on site.
That changes the work in a practical way. A fire rating belongs to a complete assembly, not to the board: one layer of 5/8-inch Type X each side of a properly built stud wall will typically achieve one hour, and two layers each side two hours, but the stud type, spacing, fasteners and insulation are all part of what was tested. The right reference is the specific UL assembly number, and inferring a rating from board thickness alone is how an inspection gets failed.
The other constant is schedule. Drywall sits between the rough-in trades and everything that follows, so it is squarely on the critical path — and a delay here pushes finishes, fixtures and the certificate of occupancy behind it.

Commercial Drywall Installation in Davenport, IA
Office Drywall Installation
Partitions, corridors, private offices and conference rooms. The recurring requirement is sound rather than fire — people notice acoustic privacy in a meeting room immediately and forget everything else about the walls. Meeting that means understanding that STC and fire rating are independent properties: an assembly can be two-hour rated at STC 40, or STC 60 with no rating at all. Raising STC needs resilient channel, staggered studs or damped board, not simply thicker panel, and that has to be designed in rather than added at finishing.
Retail Drywall Installation
Storefronts, sales floors, stockrooms and fitting rooms, usually on a compressed schedule tied to a lease start or a trading date. Retail walls take more physical abuse than office walls, so backing behind fixture runs and impact-resistant board in high-contact areas are worth specifying early. Ceiling heights are frequently greater than residential, which pushes stud gauge up — a 3-5/8 inch stud at 25 gauge is good to roughly ten feet, and taller walls need heavier gauge to stay stiff.
Restaurant & Hospitality Drywall
Dining rooms, bars, kitchens and back-of-house. Two things drive the work: moisture and separation. Kitchens and areas behind wet equipment need moisture-resistant or cement board rather than standard panel, and the separation between a commercial kitchen and adjoining occupancies is usually a rated assembly. Acoustic performance matters more in hospitality than people expect, since a dining room that carries sound badly is a room guests do not return to — and that is a wall assembly decision made long before anyone hangs soft furnishings.
Medical & Professional Office Drywall
Clinics, dental and medical suites, labs and professional offices, where requirements are tighter and inspected more closely. Patient privacy drives real STC requirements between consult rooms. Imaging rooms may need lead-lined board, which is heavier and needs framing and fixings specified for it. Finish schedules run higher because surfaces have to be cleanable, and backing for wall-mounted equipment, rails and casework has to be in the right place before board closes the wall — retrofitting blocking into a finished clinic wall is an expensive way to learn that lesson.
Commercial New Construction Drywall
Whole-building interior board on new construction, hung after mechanical, electrical, plumbing and fire-suppression rough-ins have passed and insulation is in. This is the cleanest version of commercial work because the framing is open, access is unobstructed and there is no occupied space to work around. It is also the most schedule-sensitive: drywall sits directly on the critical path between rough-in and finishes, and every day lost here is a day off the end of the schedule rather than a day absorbed somewhere.
Signs You Need Commercial Drywall Installation
- A new commercial interior is framed and rough-ins have passed inspection
- Project documents specify rated assemblies or STC requirements
- A tenant space needs partitions built before a lease start date
- Existing partitions do not meet a required rating and have to be rebuilt
- Millwork, equipment or wall-hung fixtures need backing before walls close
- A finish schedule names a level the current surface does not meet
How Commercial Drywall Installation Works
- 1
Review Drawings, Specification and Assemblies
The job starts on paper. Wall types are cross-referenced against the schedule to establish which partitions are rated and to what period, which carry an STC requirement, and where moisture-resistant or impact-resistant board applies. Rated walls are traced to their specific listed assembly, because the rating belongs to the tested assembly — stud gauge and spacing, fastener type and pattern, board layers, insulation and joint treatment are all part of what was listed, and substituting any of them voids it. Finish levels are noted by area. Where drawings are ambiguous or an assembly reference is missing, that is raised as a question before material is ordered rather than resolved by assumption on site.

Frame, Back, and Coordinate
Metal studs are selected for wall height and loading rather than defaulted. A 3-5/8 inch stud at 25 gauge and 16 inch centers carries drywall on a standard partition to roughly ten feet, which covers most tenant work; taller walls in lobbies and retail need heavier gauge to stay rigid. There is a genuine trap here worth naming: two different products are sold as 20 gauge — a 30 mil drywall stud and a 33 mil structural stud — and they look nearly identical while only the heavier one carries load. Backing and blocking go in for everything that will hang on the wall later, and the layout is coordinated against the other trades' rough-in so nothing gets closed in prematurely.

Board to the Listed Assembly
Panels go up in the layer count, orientation and fastener pattern the listing specifies. On a rated wall, joints in the second layer are offset from the first, board runs to the underside of the deck where the assembly requires it rather than stopping at the ceiling grid, and head-of-wall and penetration firestopping is installed as detailed. Type X is used where specified — typically 5/8 inch, giving one hour with a single layer each side and two hours with a double layer, though always as a property of the whole assembly rather than the board. Sound attenuation insulation and any resilient channel go in as designed. Deviations get raised with the general contractor, not absorbed quietly.

Finish to the Schedule and Hand Over
Taping and coating are taken to the level named for each area — typically Level 4 through general space and Level 5 in lobbies, conference rooms and anywhere with feature lighting that will rake across a surface. A schedule is a requirement rather than a range, so what is delivered is recorded in writing for the record, which matters when a painter or an owner queries it later. Work is scheduled around the following trades so that painting and ceilings are not held up, and the space is left clean, dust-controlled and ready for the next contractor rather than swept and abandoned.
What Does Commercial Drywall Installation Cost in Davenport, IA?
- Total board area and the proportion of it in rated assemblies
- Number of board layers, since a two-hour assembly doubles the material and the coating
- Metal stud gauge and spacing, driven by wall height and loading
- STC requirements, which add insulation, channel or specialist board
- Finish level by area, and how much of the space is at Level 5
- Ceiling height and access, including lifts or staging
- Schedule — after-hours or phased work in occupied buildings costs more
- Specialist board where specified, such as impact-resistant or lead-lined
| Service | Cost Per Sq. Ft. | Typical Job |
|---|---|---|
| New Drywall Installation | $1.50 – $3.00 per sq. ft. | $1,000 – $3,254 per project |
| Small Patch or Hole | $75 – $350 per patch | $300 – $500 for a contractor visit |
| Larger Wall Repair | $500 – $800+ per patch | Scales with how much board comes out |
| Ceiling Repair | $297 – $472 per hole | $220 – $1,300 for the full ceiling |
| Water-Damaged Drywall | $500 – $2,500+ | Depends how far the moisture traveled |
| Texture Matching | $150 – $450 per patch | Runs 30 – 40% above a smooth finish |
Based on 2026 national cost-guide data from Angi, HomeGuide, and Homewyse. Quad Cities rates land above or below these ranges depending on ceiling height, access, texture type, and how much board has to come out before new board goes back in. Water damage is the widest range on the table because the scope isn't known until the wall is opened. You get a firm number after someone sees the job.
Commercial pricing tracks the specification far more than the square footage. The same floor area can differ substantially in cost depending on how much of it sits in rated assemblies, how many layers those require, and what the finish schedule calls for. The item that most often surprises owners is the second layer on a two-hour wall, which roughly doubles both board and the coating that follows it. Schedule is the other real variable: work in an occupied building outside trading hours costs more than the same work on an empty floor, and it is worth pricing both ways before assuming the constraint is fixed.
What to Look for in a Davenport Commercial Drywall Contractor
They Reference the Listed Assembly, Not the Board
A rating belongs to a tested assembly. Anyone describing a wall as one-hour because it has 5/8 inch board on it has skipped the part that actually satisfies an inspector.
They Know STC and Fire Rating Are Separate
They are independent properties and conflating them is common. A contractor who explains that a rated wall is not automatically a quiet one is worth listening to on the rest of the specification.
They Ask Where the Backing Goes Before Boarding
Millwork, monitors, grab rails and equipment all need blocking. Retrofitting it into a finished wall is expensive and avoidable, and asking early is a marker of someone who has been called back to do it late.
They Raise Drawing Conflicts Rather Than Resolving Them Silently
Missing assembly references and contradictory wall types are normal on real projects. Flagging them before ordering is how they get resolved cheaply instead of at inspection.
Residential & Commercial Commercial Drywall Installation
Residential
Residential drywall is covered on the installation and basement pages, and it is genuinely different work: no rated assemblies, no specified finish schedule, and decisions made with a homeowner on site rather than against a drawing set. Contractors who do both keep the standards separate rather than applying commercial habits to a house or residential shortcuts to a rated wall.
Commercial
Commercial installation is specification-driven from start to finish. What the documents say governs, deviations are raised rather than absorbed, and the delivered finish level is recorded. Work is sequenced against the general contractor's schedule, since drywall sits on the critical path between rough-in and everything that follows.
When Commercial Drywall Installation Isn’t the Right Call
- Small residential jobs. This is specification-driven commercial work; a house is better served by the residential pages.
- Projects without drawings or an assembly reference where a rating is required. That needs a designer first — guessing at a rated assembly is not something to take on.
- Anyone wanting a rated wall built to a lower specification to save money. The rating either exists as listed or it does not, and there is no partial version of it.
- Structural framing. Load-bearing steel is a different trade; light-gauge partition framing is covered on the metal stud framing page.
- Addresses outside the Quad Cities.
Serving Nearby Cities
Each city below has its own page, because what is behind the wall genuinely changes across the river. Housing age swings hardest: about a third of Rock Island’s housing predates 1940 against roughly 5% of Bettendorf’s, which decides whether a job starts as plaster work or board work before anyone measures anything.
Frequently Asked Questions
- What makes a drywall wall fire-rated?
- The complete assembly, not the board. A single layer of 5/8 inch Type X each side of a properly constructed stud wall will typically achieve a one-hour rating, and two layers each side two hours — but the stud type and spacing, fastener type and pattern, insulation and joint treatment were all part of what was tested. The correct reference is the specific listed assembly number from UL or the Gypsum Association Design Manual, and substituting any component voids the listing.
- Is a fire-rated wall also soundproof?
- No, and assuming so is a common and expensive mistake. Fire resistance and sound transmission class are independent properties. An assembly can be two-hour rated at STC 40, or reach STC 60 with no fire rating at all. If acoustic privacy matters — conference rooms, consult rooms, tenant separations — the STC requirement has to be specified separately and met with resilient channel, staggered studs, sound attenuation or damped board.
- What STC rating do walls between tenant spaces need?
- Where walls separate dwelling units from each other or from public and service areas, the IBC requires STC 50, tested to ASTM E90. Commercial tenant separations vary with occupancy and the project specification, so the documents govern. The practical point is that achieving a given STC is a design decision made before framing — it is not something that can be added at the finishing stage.
- What gauge metal studs are used in commercial partitions?
- 3-5/8 inch at 16 inch centers is the workhorse. Twenty-five gauge, which is 18 mil, is standard for non-load-bearing partitions carrying only drywall and is good to roughly ten feet. Taller walls in lobbies, atriums and high-ceiling retail move to 20 gauge, covering roughly thirteen to sixteen feet. One caution: two different products are sold as 20 gauge, a 30 mil drywall stud and a 33 mil structural stud. They look nearly identical and only the 33 mil version carries load.
- Can commercial drywall work happen while we stay open?
- Frequently, with phasing and containment. Work is staged after hours or floor by floor so part of the space stays usable, with dust barriers and protected routes for material. It costs more than working an empty floor, and it is worth pricing both ways rather than assuming the constraint is immovable — sometimes closing a smaller area for a shorter period is cheaper overall than working around continuous occupancy.
- Who decides the finish level on a commercial project?
- The project documents, and it is normally scheduled by area — Level 4 through general space, Level 5 in lobbies, boardrooms and anywhere feature lighting rakes a surface. Where the documents are silent, it is worth resolving with the architect rather than assuming, because Level 4 and Level 5 differ meaningfully in cost and the difference is very visible under the wrong light.
