Interlock Driveways & Patios in Toronto & GTA

Interlock should look good on day one and still look good after winters of freeze and thaw. Kaloutas Brothers designs and builds interlock driveways, patios and walkways across Toronto, Scarborough, Etobicoke, North York, Vaughan and Mississauga — built on a proper base, with drainage planned in, so the surface stays level.

Although we recommend Unilock products, we work with a wide range of interlock pavers, colours and patterns, and we help you choose the layout that fits your home, your driveway or patio, and how you actually use the space.

• Interlock driveway — a durable, repairable surface for cars, with a base built for Toronto winters.

• Interlock patio — level, comfortable outdoor living space for dining, entertaining and relaxing.

• Interlock walkway & steps — front walkways, side paths and stone steps, including the kind of front-yard interlock work shown in our recent projects.

• Pool decks & patios — interlock and stone around pools, patios and outdoor living areas.

• Repairs & relaying — if an existing interlock surface has sunk, shifted or is pooling water, ask about a repair or relay.

Frequently asked questions

Will interlock shift in winter?

A properly built base, edge restraint and drainage are what keep it level through freeze and thaw — that is why we build the base as part of the job.

Can you match my existing interlock?

Send us photos and we will recommend the closest colour and pattern available.

Do you also do the walkway and steps?

Yes — walkways, steps and front-yard interlock are part of the same work.

Do you work outside Scarborough?

Yes — Toronto and the GTA, including Etobicoke, North York, Vaughan and Mississauga.

Do you give free quotes?

Yes. Send us photos of your space by email to info@kaloutasbrothers.ca, and we will call you. There is no need for us to come out first. If a visit is needed, you will have to book that separately, and the cost will be advised then.

Warranty: 1 year craftsmanship only. Materials are covered by the manufacturer, not by Kaloutas Brothers.

Do you do waterproofing too?

Yes. If water is coming into your basement, see our Waterproofing page. Call +1 647-856-5566 first, then send photos of the wet area inside, and the outside of the house all the way around. We look at the photos, we call you, and then we usually come to look at the house in person.

Why the base matters

Most interlock problems — sinking, shifting, weeds and water pooling — start underneath the pavers, not on top of them. We build the base, edge restraint and drainage as part of the job, and we match the interlock to the driveway, patio or walkway it is going on.

How a project works

01 Call us first — Call +1 647-856-5566 and tell us about your project. A site visit is booked separately, and we will advise its cost at that time.

02 Design and quote - we show you paver options, pattern and layout, a design rendering and a clear price.

03 Build — excavation, base, laying, edge restraint, jointing and finishing. We use concrete structures when the project needs them, and we build drainage into the design so water flows away from your home.

04 Final walkthrough — we check levels, drainage and the finished look with you.

Kaloutas Brothers Construction is a family business, run by two brothers. Stefanos is a civil engineer and Nicholas is an architect and project manager. We design and build your project with that engineering and architectural knowledge.
