You want your pool ready for warm days, but who wants the hassle? We handle the key steps for a safe, fast pool opening in Sterling, VA, and make sure your pool is good to go. You can relax while we take care of everything.
Let us, Dolphin Pool Services, handle your pool opening, cleaning, and equipment checks. We’ll make sure your pool is safe and swim-ready.

We’ll explain what to expect from our opening service and share simple tips you can use after we finish. With the right startup and yearly care, you’ll save time and avoid bigger headaches later.

We take care of each step so your pool is safe, clean, and ready to use. We time everything right, check all equipment, and balance chemicals to keep your pool healthy and clear.
First, we remove the winter cover and check the pool area for leaves, debris, or even the occasional critter. We reconnect pumps, filters, heaters, and any automatic cleaners.
We check pump pressure, inspect skimmers, backwash or clean filters, and test heaters and chlorinators. We raise the water to the right level and vacuum out any settled debris—either by hand or with our automatic cleaner.
We also check tile, coping, and ladders for cracks or loose fittings. If we spot something, we’ll let you know right away.
We test and adjust water chemistry—pH, alkalinity, calcium hardness, and sanitizer levels. If needed, we’ll give the pool a shock treatment to clear up anything lingering.
We schedule pool openings in Sterling, VA when temperatures stay above freezing and spring weather looks stable. This timing keeps your equipment safe and helps avoid algae.
We usually recommend opening your pool 1–2 weeks before you plan to swim. This gives chemicals time to settle and water time to clear up. For saltwater pools or pools with installed chlorinators, we follow specific steps to protect salt cells and keep chlorine levels right.
If covers show damage or water pooling, we’ll replace them or professionally drain them. We also check for signs of freeze damage early so you don’t run into big repairs later.
At Dolphin Pool Services, we bring the right tools and test kits to spot issues you might miss. Our technicians handle bi-weekly or weekly maintenance, seasonal openings, and any repairs you need.
We document every equipment check and give you a clear report after each visit. Our service helps you avoid chemical overuse, keeps equipment running longer, and prevents breakdowns.
If we find anything that needs fixing, we’ll coordinate repairs or part replacements fast. We want your pool safe and swim-ready as soon as possible.

We focus on keeping your pool safe, clean, and running smoothly all year. Regular care and smart upgrades protect your investment and help you avoid expensive repairs.
We handle scheduled cleaning, skimming, vacuuming, and filter checks to keep debris out and equipment working right. For most pools in Sterling, VA, we recommend weekly skimming, bi-weekly vacuuming, and monthly filter checks during swim season.
Our team checks pump pressure, listens for odd motor noises, and tests all valves. We keep track of runtime hours and look for leaks or signs of wear. For saltwater systems or chlorinators, we adjust service as needed and monitor the salt cell.
We offer seasonal services: professional spring openings, mid-season tune-ups, and winter closings. We use industry-standard tools and keep detailed service logs so you know what we did and when.
We test for pH, alkalinity, calcium hardness, chlorine (or salt), and stabilizer using digital meters and lab strips. Early in the season, we recommend testing at least twice a week. Once things settle, weekly testing is usually enough.
We adjust chemistry with the right products: acid or sodium bisulfate for high pH, baking soda for low alkalinity, calcium chloride for low hardness, and chlorine or shock for sanitation. For salt systems, we check cell output and salt levels to manufacturer specs.
We keep careful records of test results and chemicals added. This helps prevent algae, corrosion, and scaling, and protects your heaters and filters. Trusting Dolphin Pool Services means you get safe chemical handling and accurate dosing for pools across Sterling, VA, Maryland, and the DC area.
We inspect for surface issues like plaster wear, stained tile, or cracked coping and recommend repairs or resurfacing if needed. Popular upgrades include pebble plaster, quartz finishes, and new tile for a fresh look.
We can upgrade equipment to boost efficiency and cut costs. We install variable-speed pumps, energy-efficient heaters, better filters, and LED pool lighting. Automation systems let you schedule and control everything remotely.
We handle safety upgrades too: new covers, updated handrails, and ADA-compliant steps. For older pools, we can plan renovations in phases to help with budgeting. We follow all local codes and handle permits as needed.
