Tile setting in Des Moines: hiring and planning

Define the job before comparing estimates

Give each installer the same description: the room, approximate dimensions, tile you have selected, desired pattern, and whether you want removal included. Send photographs of the whole surface and any cracks, loose tiles, stains, or damaged edges. Ask the installer to inspect the base before committing to a fixed preparation price.

For a floor, ask how the installer will assess the existing base and handle transitions at doors and adjoining rooms. For a backsplash, agree on outlet openings, exposed edges, and where the pattern starts. For a shower, request a written description of the waterproofing assembly and who will handle the drain, valve, and supply connections.

Set a process for discoveries after removal. Ask the contractor to photograph damage, explain the proposed repair, and obtain your written approval before adding work. Include an allowance or unit price for uncertain preparation only when both parties understand what it covers.

Check Iowa registration and plumbing credentials

Iowa requires individual and business construction contractors to register with DIAL when they earn at least $2,000 a year from construction. DIAL also says subcontractors must register themselves. Ask for the business name and registration number, then use the contractor-check option on DIAL's Contractor Registration page. [1]

Ask who will perform each part of the job. Iowa requires plumbing contractors to hold a board license and maintain DIAL registration. The state's Contractor License page provides access to a public portal for license searches. Use that route when your tile project includes plumbing services, and match the listed business to the contractor named in your agreement. [3]

DIAL describes annual renewal for ordinary construction registration and a joint three-year registration and contractor license for plumbing and mechanical contractors. Check the applicable record's status rather than assuming that every credential follows the same renewal cycle. [1]

Request a current insurance certificate and ask whose work it covers. For licensed plumbing contractors, Iowa requires public liability coverage of at least $500,000 and a performance bond of at least $5,000. Those plumbing requirements do not establish a tile-only installer's coverage. [3]

Compare the full scope and tax treatment

Compare estimates line by line before comparing totals. Ask each contractor to identify tile supply, removal and disposal, preparation, setting materials, grout, edge trim, waterproofing, plumbing, and cleanup. If you supply tile, agree on who checks quantities and condition, who orders additional material, and how the contractor handles delays.

Iowa's Department of Revenue lists tiling as a service not subject to sales tax when separately itemized. Ask the contractor to show tiling labor as its own charge and explain any tax charged on materials or other services. Avoid applying a single tax assumption to the entire bathroom project. [2]

For qualifying new construction, reconstruction, alteration, expansion, or remodeling, Iowa says the contractor pays sales or use tax on purchased building materials and does not collect tax from the customer on the construction labor or materials. Repairs and installations outside those classifications have different rules. Ask how the contractor classified your scope and request an explanation of the invoice. [2]

Agree on access, approvals, and return to use

Ask for a schedule that distinguishes removal, preparation, installation, grouting, and return to use. Have the installer specify when you can walk on the floor, move furniture back, or use the shower under the selected products' instructions. Plan bathroom access around that written schedule.

Confirm where the crew will cut tile, store materials, and carry debris. Discuss dust containment, protection for adjoining finishes, parking, pets, and daily cleanup. Approve the layout and visible edge details before the installer starts setting tile.

DIAL directs contractors to contact city or county government for each project's local requirements. Ask the contractor to confirm the requirements for your address and complete scope before work begins, including any plumbing or structural changes. The supplied state guidance does not establish a Des Moines permit exemption or application procedure. [1]

Before final payment, walk through the work with the contractor and record any unfinished items. Request care instructions, product names, spare tile, and written warranty terms. Keep the approved scope, change orders, photographs, and itemized invoice together.

Frequently Asked Questions

Does construction registration cover the plumber too?

Iowa treats plumbing contractor licensure and DIAL registration as separate requirements. A plumbing contractor must maintain both. Ask for the plumbing business's license and registration information when the scope includes plumbing services. [3]

Should a contractor charge sales tax on tiling labor?

Iowa lists tiling among services not subject to sales tax when separately itemized. Materials and other services can receive different treatment depending on the project classification. Ask for an itemized invoice and an explanation of any tax charges. [2]

Do these sources establish whether my project needs a city permit?

No. DIAL directs contractors to contact city or county government for each project's local requirements. Ask the contractor to confirm the requirements for your address and proposed work before starting. [1]

Can I compare installers using only a price per square foot?

Ask each installer to price the same scope first. Compare removal, preparation, installation, trim, cleanup, and any shower or plumbing work. Record exclusions and the process for additional work so you understand the total commitment.
