Services
Pool Opening
Our comprehensive pool opening service prepares your pool for swim season. We inspect and document equipment condition, test water chemistry, balance chemicals using owner-provided supplies, and provide initial chlorine treatment. Options include cover removal and debris vacuuming. Technicians ensure proper heater function and ladder installation while offering recommendations for equipment upgrades or repairs to prevent future issues.
Pool Repair
We diagnose and repair all pool equipment including pumps, filters, heaters, and automation systems. Factory-trained technicians evaluate repair versus replacement scenarios, prioritizing cost-effective solutions. As a certified warranty station for major brands like Pentair and Hayward, we handle warranty claims and ensure proper installation of replacement parts to maintain manufacturer guarantees.
Pool Maintenance
Weekly and bi-weekly maintenance packages include water chemistry testing, debris removal, filter cleaning, and equipment inspection. Our technicians provide monthly computerized water analysis, vacuum pools, and deliver detailed condition reports. We offer vacation service to maintain pool quality during homeowner absences and pool school sessions to educate clients on basic maintenance practices.
Pool Closing
Our winterization service protects pools during off-season. Technicians lower water levels, add protective chemicals, install winter covers, and drain plumbing lines. Optional services include spa winterization, filter grid servicing, and antifreeze line treatment. We recommend two winter check-ups to maintain chemical balance and prevent freeze damage to equipment and pool structures.
Pool Automation
We install and maintain automated pool systems that control sanitation, pH balance, cleaning cycles, and temperature remotely. Our technicians program wireless and mobile-enabled controllers to optimize energy efficiency while maintaining water quality. Automation upgrades include saltwater chlorinators and robotic pool cleaners that reduce manual maintenance requirements.

Twin Pool & Spa is one of those service companies that you hope beyound hope you will run into in your life time. I was in a bad spot in mid- August when my filter pump went out and my then pool service company of which I had been a cutomer for 23 years said they could not get out for two weeks. Reluctantly, I agreed to wait but asked if when they came to make sure they had the appropriate pump on their truck.
They assured me they would. On Friday the day of the service call they came determined it was in fact the pump and told me it would be another four days at the earliest before they could return and fix the problem. At this point I started calling around to find someone who could come out. Thank God I found Twin Pool & Spa they got the pump and came out on Sunday and fixed my pool. Subsequently I have swiched my pool services to Twin Pool & Spa. My closing in October was the smoothest least intrusive closing I have been through in 23 years.
THANK YOU TWIN POOL & SPA

I live in Bethesda, MD and have been searching for a locally owned pool service company that has a wide-ranging set of support. My search is OVER! I cannot say enough about Twin Pool & Spa. The twins Derrick & Brent (yes, they really are twins) visited my home, saw my pool and said "let us handle this please." The rest is history! Our pool is now in good hands hopefully for a very long time. This is a family-owned and run business. When you call, ask for Martha (that's the mom) who is awesome too. I highly recommend Twin Pool & Spa!!

Excellent service and also such friendly technicians! It's a family business and it's so cool how much they all care about their company, it really shows. Feeling good about having a pool company nearby that can keep my water in check and my pool heater running good.

One of the few companies in the area who will service an above ground pool. They provided friendly service, recommended the most affordable fix, and came to my house within a few days of me asking. Visit 1: Diagnosis and recommend I order parts. Visit 2: Install parts I ordered and fix. Only charged me for labor time which worked out as 1hr despite 2 visits. Problem (needed new filter) completely fixed and lasted all Summer so far.
They came less than 48hrs after parts I ordered arrived. Tech (Brett) said they know the timeliness necessary on broken filters and want to take care of customers. Will definitely recommend and will be my first call for any future needs (including if I ever upgrade to an in-ground pool).

We have been absolutely thrilled with Twin Pool and Spa. This is our first season owning a pool, and they answered our many questions and provided great advice. Their rates are reasonable, and they are very knowledgeable and super pleasant. The pool was sparkling clean with stable chemistry all summer. I highly recommend this family-run business!
