Pool Construction
8 common questions
How much does an inground pool cost in the Twin Cities?+
An inground pool in the Twin Cities and Western Wisconsin typically costs $40,000–$125,000 in 2026, depending on size, features, and site conditions. Vinyl liner pools (our specialty) are the most popular and cost-effective option for Minnesota's climate. Our complete packages include 14-gauge steel walls, Hayward equipment, and a lifetime transferable warranty. Minnesota pools cost 15–25% more than Sun Belt installations due to deeper excavation and freeze-resistant construction. We provide detailed written estimates with no hidden fees — contact us for a free quote.
How long does it take to build a pool in Minnesota?+
On-site construction takes 2–3 weeks, with the total project running 8–12 weeks from design to first swim. The build season in Minnesota runs May through October. Permits are the biggest variable — Woodbury and Stillwater typically process in 2–3 weeks, while some cities take up to 8 weeks. Starting the planning process in late winter or early spring is the best way to ensure you're swimming by summer. We handle all permitting.
What types of inground pools do you build?+
We specialize in steel wall vinyl liner inground pools — the most popular and cost-effective type for Minnesota's climate. Our 14-gauge steel walls with concrete footings set below the 60–80 inch frost line are specifically engineered for freeze-thaw cycles. Pools can be any rectangular dimension from 14x28 to 20x40+, with custom shapes available. All packages include Hayward equipment, Latham liners, and a lifetime transferable warranty on the steel structure.
How does Minnesota's climate affect pool construction?+
Minnesota's frost line reaches 60–80 inches deep — among the deepest in the country. Pools must be engineered for freeze-thaw: concrete footings below the frost line on sono tubes set 4 feet on center, 14-gauge (not 16-gauge) steel walls with triple bracing, granular backfill for drainage, and plumbing that can be fully blown out for winterization. Pools built with Sun Belt methods will fail in our climate. Pools built correctly last decades — our earliest installations from the 1990s are still going strong.
What is included in a Paragon pool package?+
Every package is turnkey: 14-gauge steel walls, concrete footings, Hayward SuperPump variable-speed pump, Hayward 250K BTU heater, Hayward C-4000 filter, walk-in steps, underwater LED light, solar cover with reel, Polaris robotic cleaner, full accessory kit, and a lifetime transferable warranty. Site-specific costs (permits, electrical, gas, fencing) are quoted separately with clear line items. No hidden fees — we provide a complete written estimate before work begins.
Do you handle the permit process?+
Yes — we handle 100% of the permitting for every project in Minnesota and Western Wisconsin. Most Twin Cities east metro municipalities require a building permit, electrical permit, and sometimes a plumbing permit for inground pools. Permit timelines vary: Woodbury and Stillwater typically approve in 2–3 weeks, while cities like Cottage Grove or Forest Lake may take 4–8 weeks. We submit all applications, coordinate inspections, and ensure your project meets local code. You never have to visit city hall.
How deep can an inground pool be?+
Most residential inground pools in Minnesota range from 3.5 feet at the shallow end to 8 feet at the deep end. A common configuration is a 3.5-to-6-foot graduated depth for family use, or a 3.5-to-8-foot layout for diving. Minnesota code requires a minimum depth of 7.5 feet under a diving board. We design depth profiles to match how your family actually uses the pool — wading with kids, lap swimming, or diving — during the initial consultation.
What size pool will fit my yard?+
Most municipalities in the Twin Cities require pools to be set back at least 10 feet from the property line and 5 feet from the house. A typical east metro lot (80x120 feet) can comfortably fit a 16x32 or 18x36 pool with a patio surround. Smaller lots work well with a 14x28. We evaluate your yard's slope, drainage, soil conditions, underground utilities, and setback requirements during the free in-home consultation — and design a pool that maximizes your usable space.
Cost & Financing
4 common questions
What financing options are available for a pool?+
Most pool buyers in Minnesota finance through a Home Equity Line of Credit (HELOC), which typically offers the lowest rates (currently 7–9% APR) and potential tax-deductible interest. Personal home improvement loans are another option, with approval in 1–3 days and no home equity required. Some buyers use a cash-out refinance if rates are favorable. We don't offer in-house financing, but we work with customers every season who finance and can point you toward lenders experienced with pool projects.
Does a pool increase my home's resale value?+
In the Twin Cities metro, a well-maintained inground pool typically adds $20,000–$50,000 to a home's resale value, recovering 40–60% of the installation cost. Pools add the most value in family-oriented east metro communities like Woodbury, Lake Elmo, and Stillwater where outdoor living is a priority. The real ROI is in daily use — most of our customers tell us it's the best investment they've made in their home. A quality installation with an automatic cover and good maintenance makes your property stand out in the market.
What does annual pool maintenance cost?+
Annual maintenance costs for a Minnesota pool run $2,000–$5,000 depending on pool size and features. Breakdown: chemicals ($500–$1,000 per season, less with a salt system), energy for pump and heater ($600–$3,000 depending on usage), professional opening and closing ($300–$600 combined), and occasional equipment maintenance. Our chemical start-up package is $225 and includes everything for the first month. We also offer weekly maintenance service across the east metro and Western Wisconsin.
Do I need to update my homeowner's insurance for a pool?+
Yes — contact your insurance provider before construction begins. Most Minnesota homeowner's policies require you to notify them of a pool installation. Typical annual premium increases range from $50–$200. Your insurer will likely require a 4-foot non-climbable fence with a self-closing gate, or an ASTM-rated automatic safety cover. Umbrella liability coverage ($1 million+) is strongly recommended. We provide documentation of your pool's safety features (cover rating, fence specs) to make the insurance process straightforward.
Maintenance & Water Care
4 common questions
Should I choose salt water or chlorine for my pool?+
Salt systems generate chlorine automatically from dissolved salt, producing softer-feeling water with less chemical smell. A Pentair IntelliChlor or Hayward AquaRite system costs $1,500–$2,500 installed and reduces chemical purchases by 50–70% per season. Traditional chlorine is less expensive upfront and simpler to maintain. In Minnesota's shorter season, both systems work well. About 60% of our new pool customers choose salt. The key factor is personal preference — we can walk you through both options during your consultation.
How do I winterize my pool in Minnesota?+
Minnesota winterization requires lowering water 4–6 inches below the skimmer, blowing all plumbing lines clear with compressed air (every line — not just the main), adding winterizing chemical kits, installing winter cover plugs, and securing a winter safety cover. The process takes 2–3 hours for a professional crew. We close pools from mid-September through October. Proper winterization prevents freeze damage to plumbing, equipment, and the pool structure — shortcuts cause cracked pipes and thousands in spring repairs. Our closing service is $250–$400.
Do you offer maintenance plans?+
Yes. We offer weekly maintenance service throughout the swimming season (May–September) across the Twin Cities east metro and Western Wisconsin. Weekly service includes water testing, chemical balancing, skimmer and pump basket cleaning, filter checks, and equipment inspection. We also offer seasonal opening and closing packages, one-time water chemistry corrections, and equipment tune-ups. Call our Willernie showroom at (651) 653-6807 for current maintenance plan pricing.
How long does a vinyl liner last?+
A quality vinyl liner lasts 8–12 years with proper care in Minnesota. Latham liners (the brand we install) are among the longest-lasting in the industry, with UV-resistant coatings and thicker material in high-wear areas. Factors that shorten liner life: unbalanced water chemistry (especially low pH), sharp objects, and dogs with untrimmed nails. When it's time for replacement, we handle the full job in 2–3 days — draining, measuring, removing the old liner, inspecting the structure, and installing the new one. Replacement costs $3,500–$6,000 depending on pool size.
Climate & Season
4 common questions
How long is the swimming season in Minnesota?+
Without heating: 3 months (mid-June through mid-September). With a gas heater and automatic cover: 5–7 months (April through October). A Hayward 250K BTU heater can raise water temperature 1–1.5°F per hour. An automatic safety cover retains 50–70% of overnight heat, dramatically reducing heating costs. Most of our customers swim from May through September with a basic heater setup — adding an automatic cover extends that by 4–6 weeks on each end.
When is the best time to start planning a pool project?+
January through March is the ideal time to start planning for a summer pool. This gives us time for design, permitting (2–8 weeks depending on your city), and scheduling before the May construction season begins. Our winter consultations are unhurried, and you'll have first priority on the build schedule. If you contact us in May or June, we can sometimes accommodate a late-summer build, but the schedule fills quickly. The earlier you start the conversation, the more flexibility you'll have on timing and design.
Do I need a fence around my pool?+
Yes. Most Twin Cities municipalities require a 48-inch (4-foot) non-climbable fence with a self-closing, self-latching gate. Some cities require 60 inches (5 feet). Fencing typically costs $18–$28 per linear foot. In many jurisdictions, an ASTM-rated automatic safety cover (like the SwimWise and Coverstar units we install) can satisfy the barrier requirement in place of a fence — but verify with your city first. We advise on the specific requirements for your municipality during the consultation.
What are the benefits of an automatic pool cover?+
An automatic pool cover provides three major benefits: safety (rated to ASTM F1346, supports the weight of a child or pet), energy savings (retains 50–70% of overnight heat, cutting heating costs by up to 60%), and cleanliness (keeps debris out, reducing chemical use and cleaning time). In Minnesota, an automatic cover extends your swimming season by 4–8 weeks total. Coverstar and SwimWise are the two brands we install — both are motorized, one-touch operation, and can satisfy fence requirements in most municipalities. Installation adds $12,000–$22,000 depending on pool size.
Hot Tubs & Saunas
3 common questions
What's the difference between a hot tub and a swim spa?+
A hot tub seats 4–8 people in heated water (100–104°F) for relaxation and hydrotherapy — most models are 7x7 feet and cost $8,000–$18,000 installed. A swim spa is longer (12–19 feet), produces a current for swimming in place, and serves as both a fitness pool and hot tub. Swim spas cost $25,000–$50,000 installed. For Minnesota homeowners who want a year-round water experience without the footprint of a full pool, a swim spa is an excellent compromise. Visit either showroom to compare models side by side.
What types of saunas do you offer?+
We offer both traditional Finnish saunas and infrared saunas for indoor or outdoor installation. Traditional saunas heat the air to 150–190°F using an electric or wood-fired heater and can be used dry or with steam. Infrared saunas operate at a lower 120–150°F, heating the body directly with infrared panels. Traditional saunas are more popular with our Minnesota customers and range from $4,000–$15,000 depending on size and materials. Both types are designed for year-round use — especially satisfying on a 10-below January evening.
Can I use a hot tub year-round in Minnesota?+
Absolutely — hot tubs are designed for year-round use, and most of our customers use theirs more in winter than summer. Modern hot tubs with full-foam insulation and locking hard covers maintain 104°F water even when the air temperature is well below zero. Monthly energy costs run $30–$60 in summer and $60–$100 in the coldest months. The key is proper insulation, a quality cover, and placing the tub where you can access it easily in snow. Our Willernie and Stillwater showrooms have operating models you can test in any weather.
Working With Paragon
6 common questions
Is owner Mike Henry really on-site for every project?+
Yes. Mike Henry has been building pools in the Twin Cities since the early 1970s and personally supervises every Paragon installation. He's on-site during every critical phase: excavation, wall placement, equipment sizing, and final inspection. This isn't a sales promise — it's how we've operated for 35 years. As Tom and Deb Campbell wrote: 'Paragon stands head and shoulders above the pack.' That reputation was built one project at a time, with Mike on every one.
Do you serve Western Wisconsin?+
Yes. Paragon Pool & Spa serves the entire Twin Cities east metro and Western Wisconsin, including Hudson, River Falls, New Richmond, Somerset, and Prescott. Our Stillwater showroom is less than 15 minutes from Hudson. We handle Wisconsin permits and know the local requirements in each St. Croix and Pierce County municipality. Pricing and construction standards are the same on both sides of the river.
Can I see completed projects before deciding?+
Yes — we encourage it. Our website gallery features dozens of completed pool, hot tub, and sauna projects across the Twin Cities east metro and Western Wisconsin. Both showrooms (Willernie and Stillwater) have displays and reference albums. For larger projects, we can connect you with past customers in your area who are happy to show their pools. With 2,000+ installations over 35 years, there's likely a Paragon pool within a few miles of your home.
How do I get started with a pool project?+
Start with a free in-home consultation — call (651) 653-6807 or submit a request through our website. Mike Henry or a senior team member visits your property, discusses your vision, assesses the yard (slope, soil, setbacks, utilities), and answers all your questions. There's no obligation and no pressure. Within a week, you'll receive a detailed written estimate with clear line items. From there, we handle design, permitting, and scheduling. Most customers go from first call to signed agreement in 2–3 weeks.
What warranty do you offer?+
Every Paragon pool includes a lifetime transferable structural warranty on the 14-gauge steel walls — it stays with the home if you sell. Hayward equipment carries the manufacturer's standard warranty (typically 3 years on pumps and heaters, 1 year on motors). Latham vinyl liners carry a prorated manufacturer warranty up to 25 years. Our workmanship is warranted for the life of the pool. If something we built or installed fails, we fix it. We've been honoring that commitment since 1990 — our BBB A+ rating since 1998 reflects it.
What sets Paragon apart from other pool builders?+
Three things: owner-supervised construction (Mike Henry on every job since the 1970s), Minnesota-engineered builds (14-gauge steel, frost-line footings, triple bracing — not Sun Belt shortcuts), and 35 years of local reputation (A+ BBB since 1998, 2,000+ pools, 5.0 Google rating). Many larger companies send a salesperson to your home and a foreman you've never met to the build. At Paragon, the person who designs your pool is the person who builds it. That's rare in this industry, and it's why our customers refer their neighbors.
