Frequently Asked Questions
Our award-winning basement waterproofing systems are proven to keep your home dry and healthy. We address the source of water problems, not just the symptoms, protecting your structure and your investment. We’re here to address your concerns and inquiries.
How do I know if my home may require basement waterproofing?
If you notice dampness, mould, peeling paint, musty odours, or small puddles after rain, your home may require wet basement repairs. Early action is advised to avoid potential structural damage, health risks, and costly home repairs if ignored. Basement Boss London offers free consultations.
How long does a basement inspection and foundation assessment take?
A thorough inspection and assessment of a basement and foundation by an experienced professional typically requires approximately 1 hour if the basement is unfinished. The exterior and interior of the foundation, lot grading, and surface drainage are factors to be considered.
If the basement is finished, it may be necessary to remove a section of interior drywall and insulation to properly assess. Basement Boss London is a Certified RenoMark professional, at your service.
Do I need a permit for basement waterproofing?
Basement waterproofing doesn’t require a permit; however, if licensed sub-trades are involved (electrical, plumbing, H.V.A.C., gas), a permit may be required.
Structural repairs or structural corrections require a permit. As a licensed residential general contractor in London, ON, we handle all required permits and inspections on your behalf.
What is the best way to repair or waterproof a foundation crack?
A foundation crack waterproofing solution must be based upon the type of foundation, the condition of the foundation, and the specific location of the crack. A foundation crack may be waterproofed from the exterior or the interior. Is the foundation surface sound (newer poured cement)? Are there exterior obstacles preventing excavation (an attached garage)? Is there an interior load-bearing wall or a gas fireplace in front of the crack? There are many factors to consider.
An experienced professional will offer both exterior and interior waterproofing solutions and provide credible reasons for the recommended ‘best solution’.
Our team specializes in foundation crack repairs and waterproofing as part of our basement waterproofing service. We first ensure your foundation is structurally sound before installing any waterproofing system.
Do you provide both interior and exterior waterproofing options?
Absolutely. We offer both interior and exterior basement waterproofing systems. The type of system recommended will be determined by many factors, firstly, the type of foundation: poured cement, cement block, field-stone, or a combination.
Other important factors: What is the condition of the foundation? Is the basement finished or unfinished? What exterior obstacles to accessing the foundation are present (porches, decks, patios, garages, driveways, AC units, utility lines)?
Basement Boss London, are expert in providing the best solution to your wet basement foundation problems, recognized and trusted in the London and St.Thomas areas for over 2 decades.
