About Alin Alpin Pools

A Family Firm That Builds Pools Properly

We're a family-run team based in Cheam, Sutton. For more than 19 years we've designed, built and looked after pools, swim spas, steam rooms and saunas for homes and businesses across London, Surrey and England.

Who we are

One Team, From First Sketch To First Swim

Alin has worked in concrete for more than 35 years. He started out in Romania and has spent the last 19 years building pools. That's why the shell is the part we care about most: get the concrete right and everything that goes on top of it lasts.

We keep the whole job in-house. The same team surveys your site, designs the pool, builds the concrete shell, waterproofs it, tiles it and then looks after it for years afterwards. You deal with one firm from start to finish, and so does the work.

We build in reinforced concrete, sprayed or cast, or with insulated concrete formwork (ICF) where it suits the site. Every shell is rendered, screeded and tanked, then filled and left for seven days before a single tile goes on. It takes longer than skipping the test. It's also how we know a pool is watertight before it's finished.

How we work

The Parts You Don't See Are The Parts We Care About

  • Steel reinforcement and formwork for a pool and spa shell01

    Built In Concrete

    Reinforced shells, sprayed, cast or ICF, chosen to suit your ground and your design. Sprayed shells carry a 10-year warranty.

  • Tanked pool shell with tiling materials ready02

    Tested Before It's Tiled

    30mm render, 60mm screed laid level to within 1 to 2mm and a mesh-reinforced tanking membrane, then a seven-day water test.

  • Mosaic tiling under way in an indoor pool03

    Tidy, Considerate Sites

    We keep disruption to a minimum and the site clean. For hotels and other businesses we'll work out of hours to keep you trading.

    Looked After For Years

    Our own engineers service what we build, from filtration to heating and covers, with a warranty on replacement parts.

Our warranty

Guarantees In Plain Numbers

Every new build comes with written warranties on each stage of the work. Refurbishments carry a 3-year warranty on render, tanking and cement-based grout, extended to 5 years with epoxy grout. The existing structure isn't covered, which is why every refurbishment starts with a structural survey.

  • 10Years on sprayed concrete shells
  • 3Years on render and screed
  • 3Years on tiling with cement grout
  • 5Years on tiling with epoxy grout
