"Fibreglassing an old concrete pond is a specialist job rather than general landscaping, so pricing reflects that. For a pond around the size you describe, expect somewhere around six hundred to twelve hundred pounds, depending on access, the state of the existing concrete, and whether pipework or edging needs redoing at the same time. It is worth getting the concrete inspected first, since if it is cracking or shifting, fibreglassing over a failing base often just leaks again a year or two later rather than solving the underlying problem."

"For a pond around 3m x 2m, I’d expect roughly £800–£1,500, depending on depth and how much prep/repair the old concrete needs."

"Leaking Concrete Pond

Hi, we can help with this.

For a pond around 3m x 2m, fibreglassing is an excellent long-term solution. As a rough guide, you’re typically looking at £800–£1,500, depending on the condition of the existing pond and any preparation work needed before the fibreglass is applied."

"I would recommend pond sealing paint (Bonda G4 Black Pond Sealer) available online this would be more cost effective than traditional fibreglass. depending on depth this would be approximately 360+labour."

"Hi, I’d be happy to help. Fibreglassing a leaking concrete pond is something I can do. Could you please send me a few photos of the pond, including the inside, and let me know its approximate depth? Once I’ve seen the condition of the pond, I’ll be happy to provide you with an accurate quote."
