What to know first
When a North Arlington garage has an unknown prior coating or patch history, the first decision is how the work area will be opened for inspection. Alpine serves North Arlington and Bergen County as a service-area business, and the installation plan should identify what must be removed from the slab, what can stay protected, and how long access will be restricted. Photograph the existing floor, mark visible transitions or repairs, and measure the area that must be cleared. Ask for a phased schedule covering relocation, inspection, preparation, coating, cure time, and storage replacement.
A prior coating cannot be judged reliably from color alone. Ask the installer to identify whether the surface appears coated, painted, patched, contaminated, or mixed, and what testing or inspection will guide the preparation choice. Mechanical profiling such as diamond grinding may be appropriate, while old-coating removal, cleaning, crack or spall repair, and contaminant checks may also be needed. Moisture assessment is worth discussing when appropriate. The estimate should state what is included if the substrate differs from expectations and who authorizes extra work.
Preparation decisions affect both the schedule and the system recommendation. A sound, clean, properly profiled surface gives the coating a better basis for installation, but no coating should be presented as structural repair, waterproofing, or a universal answer to moisture. Northeast garages may encounter road salt, grit, wet vehicle traffic, hot tires, and temperature changes; these are reasons to discuss cleaning, cure conditions, and use limitations, not proof of a particular condition at your property. Before comparing colors, ask Alpine to document the observed slab condition, proposed preparation, and any unresolved uncertainty.
Only after the substrate plan is clear should you compare epoxy, polyaspartic, and decorative options. Epoxy may suit a project where its characteristics and appearance align with the intended use; polyaspartic may offer a different installation profile or design direction. Full-broadcast decorative flake can provide a varied visual finish, while metallic epoxy produces a distinctive pattern and may add 20% when it qualifies as a custom finish. Ask what each system requires, how repairs will show through or be treated, how texture is selected, and when the floor can receive foot or vehicle traffic. Compare documented tradeoffs rather than marketing labels.
Storage should be planned around the final work area, especially when old shelving or cabinets hide portions of the slab. Decide which items need closed cabinets, which should remain visible and reachable on slatwall, and which seasonal goods can occupy overhead storage. Confirm wall, ceiling, door, lighting, and vehicle clearances before approving a layout. If existing units are being reused, ask whether they must be detached and whether their feet or anchors affect preparation. Your planning takeaway is to draw a simple elevation of each storage wall and label every item that must remain accessible.
Alpine’s starting floor-package prices are $1,799 for one car and $2,999 for two cars. The final estimate may change with floor area, preparation, old-coating removal, repairs, moisture-related assessment, selected finish, and access requirements. Metallic and qualifying custom finishes may add 20%. A useful written proposal should separate the base coating from preparation allowances and storage, identify the method for handling unknown prior materials, state cure and access timing, and describe approval steps for concealed conditions. This makes competing estimates easier to compare and reduces the risk of treating an uncertain slab as a routine surface.
The floor work is covered by a 5-Year Limited Labor Warranty governed by written terms, while manufacturer warranties are separate. Review care instructions, exclusions, and any conditions that could affect coverage before signing. For a North Arlington homeowner, the next step is to clear a representative section, gather any prior repair or coating information available, photograph the entire slab, and request an inspection-based proposal. Ask the installer to provide a primary preparation plan, a contingency for incompatible material or additional repair, and a clear finish sample process. Even without hiring Alpine, that record gives you a more disciplined basis for choosing a contractor.
Document an uncertain slab
- Photograph coating edges, patched areas, cracks, spalls, stains, peeling, and transitions before items are moved.
- Record any known paint, sealer, repair, flood, chemical, or cleaning history and distinguish facts from guesses.
- Ask what inspection, adhesion checks, contaminant review, or moisture assessment will be used when appropriate.
Compare proposals by risk
- Separate mechanical profiling, old-coating removal, cleaning, repairs, and moisture-related work from the coating price.
- Require a written procedure for approving additional preparation if the prior material cannot accept the planned system.
- Confirm the selected epoxy, polyaspartic, flake, or metallic finish, access timing, cure guidance, warranty terms, and exclusions.

Frequently asked questions
Can Alpine coat a garage floor with an unknown old coating?
Alpine can inspect the slab and discuss preparation options, but the written proposal should identify the existing material, removal or profiling assumptions, and contingencies before work begins.
Why does prior patching matter?
Patches can differ in texture, porosity, or soundness, so the preparation and repair plan should explain how those areas will be evaluated and treated.
Are epoxy and polyaspartic interchangeable for a North Arlington, NJ garage?
No. They have different characteristics and installation considerations; the suitable choice depends on the assessed slab, project timing, appearance, and intended use.
What are Alpine’s starting floor prices?
Starting floor-package prices are $1,799 for one car and $2,999 for two cars, with final pricing determined by scope, preparation, and selected options.
Does the warranty include the coating manufacturer’s coverage?
No. Alpine’s 5-Year Limited Labor Warranty is governed by written terms, and manufacturer warranties are separate documents with their own conditions. Alpine addresses that point for North Arlington, NJ in the project-specific written scope after reviewing the actual space.
