Benefits of Professional Pool Closing Services
Professional pool closing services offer numerous advantages that justify the investment for many pool owners.
Expert Knowledge and Experience
Professional pool technicians have extensive training and years of experience winterizing hundreds or thousands of pools annually. They understand pool specific requirements for different pool types (vinyl, fiberglass, concrete), equipment configurations (single speed, variable speed, automation systems), and regional climate challenges (mild winters versus harsh freeze conditions). This expertise ensures all necessary steps are completed correctly preventing costly mistakes that could cause $1,000 to $10,000 in damage. Professionals identify potential problems during winterization including equipment wear, plumbing leaks, surface damage, and water chemistry imbalances, addressing issues before they become major problems.
Time and Convenience Savings
Professional pool closing takes 2 to 4 hours for experienced technicians versus 4 to 8 hours for DIY winterization. Professionals work efficiently completing all steps in one visit including water chemistry balancing, thorough cleaning, winterizing chemical application, equipment winterization, plumbing blow out, and cover installation. This frees your time for other activities and eliminates the learning curve and potential mistakes. For busy professionals or those with multiple properties, the time savings alone justifies professional service costs.
Proper Equipment and Supplies
Professional pool services have specialized equipment including commercial grade air compressors for thorough plumbing line blow out (removing 95 to 99 percent of water versus 70 to 85 percent with shop vacuums), accurate water testing equipment for precise chemistry balancing, specialized winterizing tools and supplies, and quality winterizing chemicals purchased in bulk at lower costs. These tools ensure winterization is completed more thoroughly and efficiently than typical homeowner equipment allows.
Preventative Maintenance and Inspection
Professional winterization includes comprehensive pool inspection identifying equipment wear (pump seals, filter cartridges, heater components), plumbing issues (leaks, cracks, loose fittings), surface problems (cracks, stains, deterioration), and water chemistry imbalances. Technicians provide recommendations for repairs or replacements preventing problems from worsening over winter. This preventative approach extends pool and equipment life saving money on costly repairs.
Warranty and Liability Protection
Reputable professional pool services offer warranties on their winterization work guaranteeing that if problems occur due to improper winterization, they will address them at no cost. This protection provides peace of mind and financial security. Professionals carry liability insurance protecting you from damage claims if winterization errors cause problems. DIY winterization errors leave pool owners responsible for all repair costs.
What's Included in Professional Pool Closing
Professional pool closing services provide comprehensive winterization covering all essential steps.
Water Chemistry Testing and Balancing
Professionals test all water chemistry parameters using commercial grade equipment providing accurate results. They balance pH to 7.4 to 7.6, total alkalinity to 80 to 120 ppm, calcium hardness to 200 to 400 ppm for concrete pools or 150 to 250 ppm for vinyl pools, and verify stabilizer levels. Proper chemistry prevents corrosion, scaling, and staining during winter dormancy.
Thorough Pool Cleaning
Technicians skim surface debris, brush all pool surfaces (walls, floor, steps, benches, corners), vacuum pool bottom removing all dirt and debris, and clean or backwash filters. This thorough cleaning ensures winterizing chemicals work on water chemistry rather than being consumed by debris and contaminants.
Winterizing Chemical Application
Professionals add winterizing chemicals in proper proportions for your pool size including winterizing algaecide for 3 to 6 months algae prevention, stain and scale preventer to sequester metals and minerals, clarifier to improve water clarity, and shock treatment to eliminate bacteria and oxidize organic contaminants. They circulate chemicals for proper distribution throughout the pool.
Equipment Winterization
Technicians drain pump, filter, and heater completely removing all drain plugs and storing them safely. They remove cartridges from cartridge filters for indoor storage. They leave equipment open or remove tops to allow air circulation preventing moisture accumulation and freeze damage.
Plumbing Line Blow Out
Using commercial grade air compressors, professionals blow out all plumbing lines removing 95 to 99 percent of residual water. They continue until no more water emerges from jets and drains. They install winterizing plugs in all lines and add pool antifreeze to lines that cannot be completely drained. This thorough blow out prevents freeze damage costing $200 to $500 per location to repair.
Water Level Adjustment
Professionals lower water to 4 to 6 inches below the skimmer opening for in ground pools or per manufacturer specifications for above ground pools. They use submersible pumps for efficient water removal ensuring proper water level to prevent freeze damage while maintaining enough water to protect pool structure.
Cover Installation
Technicians install winter covers ensuring they extend beyond pool edges on all sides. They secure covers properly using adequate water bags (15 to 25 for typical pools) filled 2/3 full and spaced 2 to 3 feet apart, or safety cover springs at proper tension. For above ground pools, they install air pillows before covering. They verify covers are centered and evenly distributed preventing stress points.
Cost Comparison: Professional vs DIY
Understanding cost differences helps pool owners make informed decisions about winterization approaches.
Professional Pool Closing Costs
Professional pool closing services cost $200 to $400 for most residential pools depending on pool size (larger pools cost more), pool type (in ground versus above ground), service location (urban versus rural areas), and services included (basic versus comprehensive packages). Additional services like equipment repairs, cover installation for new covers, or extensive cleaning may cost extra. Many services offer package deals combining winterization and spring opening at discounted rates ($350 to $650 total versus $400 to $800 separately).
DIY Pool Closing Costs
DIY pool closing costs $200 to $300 in supplies including winterizing chemical kit like In The Swim Pool Winterizing Kit or Doheny's Ultimate Pool Winterizing Kit ($35 to $90), pool antifreeze ($8 to $15 per gallon, need 1 to 2 gallons), winterizing plugs like winterizing test plugs ($2 to $5 each, need 6 to 12), air pillow for above ground pools like 4 foot winterizing air pillow ($10 to $30), water test kit like Taylor K-2005 Complete Test Kit ($50 to $80), and cleaning supplies including brushes like Swimline H2O Pro Pool Brush ($15 to $40) and skimmers like Deluxe Pool Leaf Skimmer Net ($10 to $25).
