Hamilton's Trusted Exterior Cleaning Experts
A Hamilton-born business built on trust, craftsmanship, and a genuine love for this community.
Meet the Owner
Hi, I'm Netasha Yokom
BTG Exteriors is a locally owned exterior cleaning company specializing in professional window cleaning, pressure washing, and soft washing services for homes and businesses throughout Dundas, Hamilton, and surrounding Ontario communities. With more than six years of experience, our team focuses on detail-oriented service, safety, and reliable exterior cleaning results.
I was born and raised right here in Hamilton, Ontario — a place I love deeply. Growing up surrounded by the beautiful homes and natural landscapes of the Hamilton area, I developed a genuine appreciation for the care and pride that homeowners put into their properties.
I started BTG Exteriors in 2019 with one goal: to provide the kind of meticulous, professional exterior cleaning that truly makes a difference. From crystal-clear window cleaning — tackling both interior and challenging exterior tall panes — to thorough pressure washing of back patios, pool surrounds, and driveways, I use proven techniques built for lasting results. I'm not just here to do a job — I'm here to help you love your home again.
I'm fully insured, Working at Heights certified, and committed to using eco-friendly products that are safe for your family, your pets, and the stunning natural environment we're so lucky to call home. When you hire BTG Exteriors, you're not hiring a faceless company — you're hiring a neighbour who genuinely cares.
