Frequently Asked Questions
What types of pools does Diamond Stone build?
We build custom vinyl-liner pools and concrete pools, from excavation and permits through coping, interlocking, and finishing. Vinyl is our most popular choice for its value and comfort. Every project is designed around your yard and how your family will use it.
How long does a pool installation take?
Most projects run 6 to 10 weeks from excavation to swim-ready, depending on weather and permit timelines. We coordinate construction, plumbing, and electrical so there are no gaps. You get a clear schedule before we break ground.
Do you take care of permits and inspections?
Yes. We manage the full permit process with your municipality. We work regularly in Oakville, Milton, Burlington, Mississauga, and across the GTA, so we know what each city requires for pool enclosures and setbacks.
Can you do the landscaping and interlocking around the pool too?
That's our specialty. We're a Unilock Authorized Contractor, and most pool projects include interlocking patios, coping, turf, grading, and planting. One crew handles the pool and the backyard, so the whole space comes together.
What does a pool installation cost?
Every project is quoted individually based on size, finishes, access, and site conditions. As a reference, a 12x24 vinyl pool plus equipment starts at $57,000 (gas connection and electrical hookups excluded). Contact us for a free, itemized quote.
Do you offer a warranty?
Yes — all of our work is backed by a 5-year warranty. With 10+ years of experience and our Best of Houzz 2023 recognition, we build pools meant to last decades.
Why should I choose Diamond Stone over other pool builders?
We're based in Oakville at 1265 Burnhamthorpe Rd E and build across the four cities we know best: Oakville, Milton, Burlington, and Mississauga. You get a dedicated project manager, transparent fixed quotes, and a crew that does pools, interlocking, and landscaping to one standard. We make dreams come true — call 647-542-2294 for a free consultation.
