You can expect most complete projects to total somewhere between $35,000 and $90,000. We see this wide price window driven primarily by four specific choices. These factors include your total square footage, the finish level, plumbing additions, and egress window requirements. Our team at Arvada Remodeling Pros has transformed homes throughout the Greater Denver area, and we know you want a clear picture of the true cost to finish a basement in Arvada before breaking ground. Here is exactly how we typically price basement finishing [/basement-finishing/ →](/basement-finishing/) projects across the metro area. Let’s look at the current data, see what it actually tells us, and explore a few practical ways to plan your budget. | Basement Size | Basic Finish | Full Finish (bath, egress) | | --- | --- | --- | | 600-800 sq ft | $30k - $45k | $50k - $65k | | 800-1,000 sq ft | $35k - $55k | $55k - $75k | | 1,000-1,200 sq ft | $45k - $65k | $65k - $90k | | 1,200+ sq ft | $55k - $75k | $75k - $110k | ![Basement finishing cost tiers by square footage](/images/misc/basement-finishing-cost-tiers-chart-by-square-foot.webp) ## The four cost drivers, ranked The four biggest factors driving your finished basement price are square footage, bathroom additions, egress windows, and your chosen finish level. Square footage is always the most significant variable because it multiplies the cost of every material and labor hour. Our pricing models show that basic Arvada basement finishes run roughly $50 to $80 per square foot. Adding a bathroom, wet bar, and egress window pushes that rate to $75 to $100 per square foot. Let’s break down these major cost drivers. ### Square footage impacts everything Larger basements obviously cost more in total, but the price per square foot actually drops slightly as the space grows. You gain efficiency of scale with tradesmen like drywallers and painters. ### Bathroom additions require concrete work A basement bathroom typically adds $12,000 to $20,000 to your total bill. We find that the biggest cost variable here is the plumbing rough-in. If your home already has a plumbing stub-out, you save thousands. Many Arvada homes require us to trench through the concrete slab to install new drain lines. If those new pipes sit below your home’s main sewer line, you will also need a special ejector pump to push wastewater up and out. This specialized pump installation is a primary reason basement bathrooms cost more than upper-level remodels. ### Egress windows are required for safety Colorado building code requires an egress window for any legal basement bedroom, and the full Arvada basement egress window requirements [/guide/basement-egress-window-requirements-arvada/ →](/guide/basement-egress-window-requirements-arvada/) are worth reviewing before you frame. We install these to provide a safe escape route and bring natural light into the lower level. Each egress window installation runs $3,500 to $6,000. This price covers several strict municipal requirements. Arvada building code mandates the following specifications: - A net clear opening of at least 5.7 square feet. - A window well with a minimum of 9 square feet of horizontal area. - A permanently affixed ladder if the well depth exceeds 44 inches. - Full code-compliant excavation and structural support. Most of our complete basement finishes add one or two of these life-saving windows. ### Finish level determines the final polish Your choice of materials will move the final price by 15 to 25 percent on the exact same floor plan. Builder-grade carpet and stock lighting represent the most budget-friendly options. Our clients often choose luxury vinyl plank flooring with recessed accent lighting for a durable mid-range finish. At the upper end, engineered hardwood and custom millwork create a premium space. You can easily mix and match these finishes to keep the project within your target budget. ## What “included” actually includes A complete basement finish from our company provides all framing, electrical, drywall, flooring, and permits as a single fixed-price scope. We package all the essential construction steps together so you never have to juggle multiple tradesmen. The standard project includes the following core elements: - Framing with floating walls to meet Colorado shifting soil codes. - Insulation rated to IECC standards for below-grade exterior walls. - Mold-resistant drywall in any moisture-prone zones. - Flooring installation using your selected materials. - Lighting design featuring recessed cans and proper switching. - All interior doors, trim, paint, and finish carpentry. - Complete electrical wiring with dedicated circuits and GFCI outlets. - HVAC supply and return tie-ins for comfortable temperature control. - Full management of all city permits and inspections. Securing permits is a major part of this process. The City of Arvada calculates basement permit fees based on a building valuation table. You can generally expect these municipal fees to range from $1,500 to $4,000 depending on the size of the project. We handle this entire application process, including the standard two-week plan review. Items like bathrooms, wet bars, and egress windows are quoted as separate line items. This itemized approach lets you clearly see where your money goes. You can then easily mix and match these optional features to fit your financial goals. ## What’s NOT typically included (but should be planned for) Certain pre-existing house conditions like moisture issues, high radon levels, and outdated electrical panels are not part of a standard finish contract. You must resolve these structural and safety hurdles before installing any new walls or flooring. Our initial walkthrough will help identify if your Arvada home needs any of these specific upgrades. ### Moisture remediation If your basement has a history of water intrusion, those leaks must be solved first. We always address moisture problems before hanging drywall because finishing over a known leak guarantees future mold damage. Proper exterior grading or a French drain system might be necessary. Denver area clay soils hold moisture, making proper drainage critical for a dry living space. ### Radon mitigation systems Arvada sits in a known high-radon zone along the Front Range. We strongly recommend completing a professional radon test before starting your remodel. If your test results show elevated levels, you will need an active sub-slab depressurization system. Installing vent pipes and a mitigation fan typically costs between $1,200 and $2,500 in 2026. This system safely pulls the radioactive gas from the soil and vents it above your roofline. ### Electrical panel upgrades Many older homes in Lakewood and Arvada still operate on a 100-amp electrical panel. You might need to upgrade to a 200-amp service if your remodel includes high-draw additions. Common high-demand upgrades include: - A new bathroom with an electric water heater. - A dedicated home theater system. - Kitchenettes featuring mini-fridges and microwaves. - Future electric vehicle (EV) charging stations. We find that this electrical panel upgrade generally costs between $2,500 and $4,500 in the Denver metro area. Xcel Energy requires specific meter coordination for these upgrades, which can add time to your project schedule. ## Why we quote it as a fixed price We use fixed-price contracts because time-and-materials agreements shift all the financial risk directly onto the homeowner. A fixed price guarantees your final bill upfront and protects you from surprise expenses. Time-and-materials contracts work exceptionally well for the builder, but they rarely benefit you. Every project uncertainty becomes a new line item on your invoice. A soft joist, an inspector callback, or a long lead time on tile will all increase your final cost under that model. Our fixed-price contracts operate on a completely different philosophy. The process begins by completing the full design phase, confirming the exact permit path with the city, and selecting all materials. We only write the final contract after securing those crucial details. The only thing that will ever change your project price is a written and signed change order. We tell you the exact cost of any requested change before the work actually happens.
