Marlin Swim Pool Service
Clients stick with Marcus for 8 to 12 years — and consistently say they never have to think about their pool.
Marcus is consistently named as the person doing the work, and Gretel is credited for the business's responsiveness, so you know exactly who you're dealing with. The reviews are universally positive and the sample is small, so it's worth calling them directly to confirm current availability and service areas before committing — but the track record of repeat clients across both residential and commercial properties suggests this isn't a business that relies on first impressions.

About Marlin Swim Pool Service
Marcus and Gretel run Marlin Swim Pool Service as a hands-on family operation out of Edmonton, with Marcus handling the technical poolside work and Gretel supporting the business side — reviewers name both when praising responsiveness and professionalism. Marcus's depth of knowledge covers chemical balancing, chlorinator repairs, pool lighting, and chemical cleans of aged pebblecrete pools, and multiple clients describe him stepping in at short notice when equipment failures or storm damage left pools in crisis. The business works across both residential pools and commercial facilities — one reviewer manages a residential community complex and has relied on Marcus's advice for 12 years — so the range extends beyond the typical backyard service call. What distinguishes the working style is a lean approach to chemical use: at least one long-term client specifically notes that Marlin only supplies what's actually needed, rather than upselling treatments. For homeowners who want a pool they never have to think about, that set-and-forget dynamic is the consistent thread through the reviews — clients routinely mention they simply come home to a clean pool.
Best for: ongoing residential pool maintenance where you want a hands-off set-and-forget arrangement, emergency callouts when equipment fails or storms cause damage, and commercial or investment property pools that need reliable scheduled servicing.

Who actually does the pool servicing at Marlin Swim Pool Service?+
Marcus and Gretel run the business together as a family operation. Marcus handles the hands-on poolside work — chemical balancing, equipment repairs, and cleans — while Gretel is credited in reviews for the business's responsive communication and scheduling. Multiple reviewers specifically name both when recommending the service, so there's no ambiguity about who's turning up to your property.
Does Marlin Swim Pool Service handle emergency callouts?+
Yes — several reviewers describe Marcus attending at short notice when equipment failed or pools were damaged after storms, including one mention of responding after Cyclone Yasi. The pattern across reviews is that existing clients can reach Marcus quickly when something goes wrong, rather than waiting for the next scheduled visit. It's worth confirming current availability for emergency work directly, as capacity can vary for a small operator.
Do they service commercial pools, or only residential?+
Both. One reviewer manages a residential community complex and has used Marcus's services for around 12 years, specifically mentioning that his advice resolved ongoing issues with a commercial pool. If you're managing a strata or investment property pool, that experience appears relevant. Confirm the specifics of your setup with them directly to make sure it falls within what they currently service.
What do customers say about pricing and chemical use?+
A long-term client specifically notes that Marcus uses high-quality chemicals but only supplies what the pool actually needs — not a blanket upsell of treatments. Another reviewer describes the service as 'well priced.' That said, with only 10 reviews in total, there isn't enough pricing data to give a reliable range — get a quote directly and compare it against local competitors.
Can Marlin Swim Pool Service restore an old or neglected pool?+
At least two reviewers mention chemical cleans on older pools, including a 20-plus-year-old pebblecrete pool that one customer describes as looking 'brand new again' after the treatment. This type of restoration clean appears to be a service Marcus has experience with, not just routine maintenance. If your pool has been neglected or has a pebblecrete surface, it's worth asking Marcus specifically about a chemical clean assessment.
