At Diamond, we specialize in basement waterproofing, masonry services, and everything in between. Whether you’re dealing with water damage, foundation cracks, or just looking to improve the structure of your home, we’ve got you covered.
Good basement waterproofing should last many years, typically around 10 to 20 years or more, depending on the methods and materials used. At Diamond, we use high-quality materials and proven techniques to ensure your basement stays dry for the long haul.
Basement waterproofing isn’t something you need to do every year. Once your basement is properly waterproofed, it should last for years. However, if you notice new cracks, leaks, or moisture buildup, it may be time for a check-up. Regular inspections can help catch problems early.
It depends on the specific issues your basement is facing. Inside waterproofing is often quicker and more affordable, and it’s ideal for managing minor moisture problems. Outside waterproofing is typically a more comprehensive solution, addressing the root of the issue by preventing water from reaching your foundation in the first place.
Masonry is all about building and maintaining strong, durable structures using materials like brick, stone, or concrete. It’s crucial for creating safe, solid foundations, repairing walls, and building features like walkways, patios, or chimneys.
