What should a professional turf installation proposal include?
Ask for a proposal that describes the work below the grass as clearly as the finished lawn. The Synthetic Turf Council's landscape buying guidance recommends written base preparation details, drainage suited to local rainfall, separate turf and infill samples, and confirmation of the seam adhesive. A sample of grass alone does not describe an installation.
Start with a marked layout showing the turf boundary, gates, existing paving, planting beds, and anything that stays. Tell the estimator which areas dogs use, where people enter the yard, and whether another outdoor project is planned. Request a free on-site quote from ND with those uses and the existing drainage concerns in view.
- Removal: which existing materials will be excavated and hauled away?
- Ground work: what soil assessment, base preparation, and drainage work are included?
- Surface: which turf, seam layout, edge details, and infill are proposed?
- Completion: what finishing, cleanup, care instructions, and checks are included?
Site preparation: agree on access and excavation before digging
Walk the access route as well as the lawn. Ask how equipment and materials will reach the work area, where removed soil will wait for collection, and which surfaces need protection. Mark anything you want retained rather than leaving the crew to infer it from an old landscape.
Request a cross-section: a simple drawing showing the existing ground, excavation, proposed base layers, and finished turf level. Ask which depths are already specified and which depend on conditions found after removal. ND offers a free soil test; ask what it establishes for this yard and whether further assessment is needed.
Agree on a review point after excavation. If the exposed ground differs from the proposal, who explains the finding, proposes the next step, and obtains agreement before covering it? Ask for photographs of the exposed ground and included drainage work so you have a record beyond the finished surface.
Rain drainage: trace the route beyond the turf backing
For a Tacoma-area installation, ask the contractor to describe the complete water route: through the turf, into the base, and then where? Tacoma's artificial turf tip sheet describes installations with or without underdrains. Ask what drainage design the site assessment supports for your yard.
If an underdrain is proposed, ask for its route and receiving location on the plan. The city's tip sheet says a receiving stormwater facility or conveyance system must account for underdrain flows. A pipe beneath the lawn is not enough information to judge whether the proposed receiving system can handle the water.
Bring photographs of rainwater entering or collecting in the planned area. Ask whether nearby roof discharge, paved areas, or uphill ground need separate attention. Do not assume the turf installation includes changes outside its marked boundary. Put any unresolved drainage destination or connection question in the proposal for review before construction.
- What site evidence supports infiltration into the ground, an underdrain, or another design?
- Who confirms the receiving location and any connection requirements?
- Which parts of the proposed drainage can be accessed for maintenance?
- What is included if an existing drain is found to need further work?
Base preparation: what should be checked before turf covers it?
The Synthetic Turf Council describes aggregate base as both structural support and a drainage medium. Its compaction guidance also identifies appropriate moisture content as important. Ask the installer how the proposed materials, compaction method, and moisture conditions will be checked together, rather than comparing base depth alone.
Have the scope identify each base layer, its intended compacted depth, and whether separation fabric is included. If fabric is proposed, ask where it belongs and what purpose it serves in this assembly. Keep the exposed ground, base, and finished turf as separate levels on the drawing so the excavation depth is not mistaken for the base thickness.
Before covering the base, request a review of the completed levels, transitions, and any included drains against the plan. Ask what records demonstrate that the specified work is complete. For wet-weather scheduling, ask what conditions would pause excavation, compaction, or covering and how the crew will decide that work can resume.
Turf layout and seams: review the joins before cutting
Ask to see the proposed panel layout before material is cut. Mark seam locations in relation to gates, the main walking route, and the view from the house. If you are comparing layouts, ask how each changes material use and the number of joins instead of assuming every yard can be installed without seams.
The council's landscape guidance recommends an adhesive intended for synthetic grass with weather resistance. Ask which joining method is specified for the selected turf and which application conditions must be met. Have the installer explain how the forecast affects that part of the schedule, including when people and pets can use the area.
Keep the approved sample and product identification available for comparison with the delivered turf. At the walkthrough, look along the joins from more than one direction. Point out any gap, raised join, or wrinkle and ask for an assessment before accepting a proposed remedy. Appearance alone does not establish why a seam looks different.
Edges and paver transitions need their own installation detail
Ask for a different edge detail wherever the adjoining surface changes: paving, a planting bed, a fence, or a gate opening. The proposal should explain how each edge is supported and secured. Do not assume an existing paver restraint is suitable for holding the turf without the installer checking the connection.
At a patio or walkway, request a drawing of the finished relationship between the surfaces. Ask how the transition will be checked for foot traffic, gate clearance, and the planned water route. If the turf and paving are separate jobs, name who confirms that their levels and edges work together.
Include reinstatement around the work area in the discussion. Which bed edges or adjacent surfaces will be restored, and which are outside the turf scope? Ask the installer to show the completed perimeter during the walkthrough, particularly where dogs play or people regularly cross it.
Infill and finishing: confirm materials, care, and first use
Infill is the loose material placed among the turf fibers. Request its name and sample separately from the turf, then ask for the selected system's installation and care instructions. Have the proposal identify the intended quantity, finishing method, and any later care it needs. Avoid choosing solely from a label such as pet-friendly.
Ask how the installer will confirm that finishing is complete and identify any initial limits on use. Request instructions for brushing and cleaning the installed system. The council's glossary describes grooming as a way to redistribute infill and directs users to the installation company's written guidance.
For dog areas, include a practical waste collection routine in the handover. Pierce County says rain can carry bacteria from pet waste to streams and storm drains, and recommends picking it up, bagging it, and putting it in the trash. Plan daily pickup; rainfall is not a substitute. Ask separately which cleaning methods suit the installed turf.
Which Tacoma stormwater questions belong in the scope?
Tacoma's artificial turf tip sheet is dated September 2021. It describes installation as land disturbance and classifies turf as a lawn area and a pollution-generating pervious surface. Those descriptions do not establish whether your complete project needs permits or other review.
The city's current manuals page says the July 2026 Stormwater Management Manual applies to applications submitted on or after July 1, 2026. Ask the city which requirements apply to your project, including any associated paving, grading, or proposed connection. Ask who will prepare any needed information and whether that work is included in the quote.
For a property outside Tacoma city limits, identify the responsible local authority before applying Tacoma guidance. Keep the estimate conditional on unanswered site or approval questions. A promise that turf drains is not confirmation that a particular discharge arrangement is appropriate.
Compare installation scope and cost drivers before booking
Compare proposals against the same marked area and intended use. Differences in removal, access, base preparation, drainage, turf layout, seams, edges, and infill can explain why the scopes differ. Ask each installer to identify exclusions and unresolved conditions so you can compare the work offered.
Before booking, agree on the review points after excavation, before covering the base, and at completion. Request the final layout, material identification, photographs of covered work, care instructions, and a list of unfinished items. Bring that same checklist to the walkthrough rather than relying on memory.
