A site inspection is needed to identify the actual cause. **What are common signs of a basement water problem?** Common warning signs include musty odours, visible water, damp walls, water stains, efflorescence, mould or mildew, frequent sump-pump operation, and cracks in walls or floors. **What is the difference between interior and exterior basement waterproofing?** Exterior waterproofing addresses the outside of the foundation and may include excavation, wall repair, waterproofing membranes, and drainage improvements. Interior systems manage water from inside the basement using drainage and sump components. The appropriate method depends on access, foundation type, source of water, condition of the structure, budget, and long-term repair goals. **How much does basement waterproofing cost in Toronto or the GTA?** Cost depends on the cause of the leak, repair method, access, excavation depth, foundation type, structural condition, drainage requirements, and size of the repair area. GJ MacRae provides a quote after assessing the property. **How long does waterproofing take?** Some repairs may be completed in a few days, while larger waterproofing, underpinning, or structural projects may take several weeks. The timeline is determined after inspection and scope development. **Do homeowners need to leave during the work?** The website states that homeowners usually do not need to leave for many waterproofing projects. This can vary for structural work, major excavation, utility interruptions, safety requirements, or extensive interior construction. **Is a structural engineer required?** The website states that an engineer is generally not required for routine waterproofing, crack repair, or weeping-tile work. Structural repairs, underpinning, wall replacement, significant movement, or permit-controlled projects may require engineering. The company and local authority should confirm the requirement. **What is hand-excavated exterior waterproofing?** Hand excavation is an exterior repair method intended to reduce damage to landscaping and surrounding property where access and conditions permit. Suitability depends on the property and project. **Does GJ MacRae offer a warranty?** Yes. Warranty coverage depends on the repair type, scope, conditions, and written agreement.
