About us

At Stone, you’ll find we do things differently, smarter and more efficiently. We’re able to achieve great results, faster. With our up-to-the-minute database, we know where and who your current buyers are. We also look ‘further afield’ and find those outside your area with a view to moving in, resulting in more buyer competition and therefore increased sales prices.

Our greater insights lead to a smarter marketing campaign. Rather than a ‘blanket’ approach, we streamline it specifically to your target audience. We’re also able to tailor it as we go along based on our weekly buyer statistics. So rather than a lump-sum payment upfront, you only spend what’s essential – and what works – on your marketing campaign, saving you valuable money. With our wider network, sharper market-intelligence and aligned goals, our expert sales, marketing and customer-service teams work together to achieve the best result. We’re for prosperity across the board, and it’s why we do what we do, with transparency every step of the way. At Stone, our door’s always open.

We had a fantastic experience working with Lauren as first home buyers. She was incredibly helpful in guiding us through every step of the process, explaining all the jargon and making sure we understood everything along the way. She was always happy to take our calls, answer our questions and helped us move quickly. We really appreciated her support and guidance.

The best in the business!

Maria and her team are passionate and dedicated to real estate. Their knowledge and experience of the Seaforth area was outstanding, and their passion for real estate was impressive. I had 100% confidence in Maria and her team, that they sold our house for the best price possible, and trusted her every step of the campaign. It was an absolute pleasure working with Maria, Lauren and Alicia, and I cannot thank them enough for the hard work they put into selling our home.

Maria's professional approach and great advice delivered a great result. She delivered on what she said she would do with a timely outcome. She kept us well informed at all times and offered practical advice to optimise our sale. We have bought and sold a lot of properties over the years and there is one word that best sums up Maria - Professional. The team behind Maria is equally great to deal with. They provided introductions to a great external stylist company, The Styling Project that after they finished styling, we almost wanted to buy our own home. Lauren and Alicia on her team were excellent communicators and are really easy to deal with. Finally, Kirsty and her back-office team deserve a mention for their prompt follow up and availability. Negotiations with the buyers, a local family, were efficient and we were kept informed as it progressed. I suspect even the buyer recognized that Maria was a straight talker. Well done Stone team on a great result Paull & Gay Betts
