Driveways (Paved & Loose)- 16 Apr 2025
Amazing work by Adam to give us not only a large block paved driveway but also a resin surface down the side of the house, a new patio as well as a rubber crumb play area for the kids. Clear communication, attention to detail and a reasonable quote for the amount of work required. Couldn't have asked for more really. Highly recommended.

CDH Contractors have been amazing throughout our home renovation. They transformed our kitchen beautifully, giving it a fresh new look that we absolutely love. They also made a huge difference in our garden with their landscaping work, creating a space that feels inviting and well designed. The highlight has to be the garden room they built for us — it’s become our peace haven, and we now spend most weekends relaxing there. Their craftsmanship, attention to detail, and professionalism truly stand out. I would highly recommend CDH Contractors to anyone looking for high-quality work. We’ll definitely continue using them as we complete the rest of the renovations in our home.
