Common Questions

How quickly can you respond to a leaking basement or flood?
We offer 24/7 emergency waterproofing and leak repair and can dispatch quickly across the GTA and Southern Ontario. Call +1 (416) 858-4482 and our team will stop the leak, minimize damage, and secure your foundation fast.
What’s the difference between interior and exterior waterproofing, and which is right for my home?
Interior systems manage water from the inside (drains, sump pumps), while exterior waterproofing protects the foundation from the outside. We assess hydrostatic pressure, drainage, and foundation cracks to recommend the best solution—then provide a clear, upfront quote after a free inspection.
Is your waterproofing covered by a lifetime warranty?
Yes, our waterproofing comes with a lifetime warranty for long-term protection. We’re fully licensed and insured and use premium materials to ensure lasting results; warranty details are reviewed at the final walkthrough.

Exterior Waterproofing

How do I know if I need exterior waterproofing?
Common signs include visible exterior foundation cracks, wet basement corners or walls, and persistent leaks in areas with a high water table. Schedule a free exterior assessment and we’ll confirm the cause and recommend the best solution.
What does your exterior waterproofing process include?
Our 5-step process includes foundation inspection and planning, excavation, wall cleaning and crack sealing, waterproof membrane application, and weeping tile installation with proper backfill. Trained technicians use industry-best methods to build a barrier that lasts.
Is exterior waterproofing better than interior waterproofing?
Exterior waterproofing is the most effective long-term fix because it prevents water from ever contacting your foundation walls. Interior systems manage water after it enters; we’ll advise the right approach after a site inspection.
Do you offer emergency service for basement leaks or flooding?
Yes. Our emergency response team is on call to stop active leaks, minimize damage, and get your home safe fast—contact us for immediate help.
How long does exterior waterproofing take, and will it affect my yard?
Most projects take a few days, depending on foundation size and site conditions. We excavate carefully and restore the area after backfilling to leave your property tidy.

Structural Foundation

What is commercial and industrial foundation repair?
It’s engineered repair and reinforcement for high-load, high-use foundations in commercial and industrial facilities, addressing heavier loads, continuous vibrations, soil movement, and water intrusion. DrySeal designs tailored solutions so warehouses, office buildings, and manufacturing plants remain safe and reliable for decades.
What are the warning signs my facility needs foundation repair?
Common red flags include water leaks or dampness in lower levels and cracks in walls, floors, or ceilings, as well as settlement or uneven slabs. Catch issues early—DrySeal offers professional inspections to pinpoint causes and reduce downtime and liability.
Can you repair our foundation without shutting down operations?
Yes. DrySeal plans projects for minimal disruption by implementing stabilization and safety measures, securing the site, and phasing work around critical areas to protect workers, equipment, and structural integrity.
What repair methods do you use for commercial foundations?
Depending on the cause and load requirements, we use industrial-grade epoxy injection, carbon fiber straps, and steel bracing. We also implement waterproofing and drainage improvements and perform soil and load corrections when needed.
How does DrySeal’s commercial foundation repair process work?
We begin with a site inspection and engineering assessment to analyze loads and diagnose damage, then secure the site with stabilization and safety measures. Next, we perform crack repair and reinforcement, upgrade waterproofing and drainage, correct soil and loads if required, and finish with final testing and sign-off to meet structural and safety codes.
How much does commercial foundation repair cost?
Costs vary based on damage severity, building size, soil conditions, and load requirements. DrySeal provides a free assessment and a transparent, engineered repair plan with an itemized scope tailored to your operational needs.
How do I request a professional foundation assessment?
Contact DrySeal to book a free on-site assessment. Our team will inspect your facility, explain findings, and recommend the fastest, least disruptive plan to stabilize and protect your foundation.

Basement Leak Repair

What are the signs I need basement leak repair?
Watch for musty odors, visible mold, damp spots, water stains, or cracks in walls and floors. These can lead to damage and foundation issues—book a free consultation and we’ll inspect your basement before the problem escalates.
How do you repair foundation cracks and seal walls?
We inject polyurethane or epoxy into foundation cracks to create a permanent, watertight seal. If needed, we add waterproof coatings and vapor barriers on interior walls to stop seepage and protect finishes.
When do you install a sump pump and what does the process involve?
If groundwater pressure is causing leaks, we install a sump system to relieve it. Our licensed pros add a sump basin, pump, discharge line, and check valve sized for your home to keep water away from the foundation.
Do you fix leaks from the inside or the outside?
Both. We perform interior crack injection and wall sealing, and when the cause is external, we excavate, seal, and add exterior drainage so water stays out—choosing the most effective, least invasive solution after inspection.
How long do repairs take, and do you offer a warranty?
Most interior repairs are completed in a day or two, while larger exterior waterproofing projects may take longer. All work is performed by licensed professionals and backed by our lifetime waterproofing warranty for lasting peace of mind.

Sump Pump Installation

How fast can you install a sump pump and what does it cost?
Most projects are completed quickly—often the same or next day after your free consultation—and we provide a clear, written quote before work begins. Pricing depends on your home’s layout, discharge routing, and options selected, but we keep it fast, affordable, and professional.
Do you install battery backup sump pumps, alarm alerts, and check valves?
Yes—optional upgrades include battery backup systems for power outages, high-water alarm alerts, and check valves to prevent backflow and short cycling. We integrate and test these options so your system works automatically during storms, snowmelt, or high water table conditions.
Where does the sump pump discharge water, and is it safe for my foundation?
We route the discharge line to daylight or an approved drain away from your foundation and landscaping, in compliance with local codes. A properly placed line and check valve prevent recirculation and help keep your basement dry.

Basement Waterproofing

What is basement waterproofing and how does it work?
Basement waterproofing is a permanent system that prevents water from entering your home, keeping your foundation clean, dry, and safe. DrySeal designs a custom interior and/or exterior solution—vapor barriers, drainage, weeping tile, sump pumps, and crack injections—then tests it and backs it with a lifetime warranty.
How do I know if I need basement waterproofing?
Common signs include damp or musty smells, water stains on walls or floors, efflorescence, peeling paint, or seepage after heavy rain. Early seepage can lead to structural damage and mold, so book a free inspection and leak detection with DrySeal.
What’s the difference between interior and exterior waterproofing?
Interior waterproofing captures and redirects water from the inside using vapor barriers, interior drainage, crack repair, and sump pumps. Exterior waterproofing stops water at the source with excavation, heavy-duty membranes, and weeping tile; DrySeal recommends the right mix after a thorough inspection.
How much does basement waterproofing cost?
Pricing depends on your foundation size, the source of moisture, and the scope of work (interior vs. exterior, sump pump, crack repair). DrySeal provides a free, no‑obligation inspection and detailed estimate, and we help you leverage insurance coverage when applicable.
Do you offer a lifetime, transferable warranty?
Yes. Every DrySeal waterproofing system is tested for performance and covered by a transferable lifetime warranty, installed by licensed professionals with quality checks at every stage.
Can you repair foundation cracks for good?
Yes—DrySeal seals foundation cracks permanently using epoxy or polyurethane injections to stop active leaks. Crack repair is integrated into your overall waterproofing system and covered by our lifetime warranty.
Do you work with my insurance if I already have water damage?
Absolutely. DrySeal streamlines claims with moisture and leak assessment reports, photo documentation, repair estimates, and direct adjuster coordination to speed approvals and start work fast.

Basement Restoration

How do I know if my basement needs restoration?
Watch for recurring leaks or standing water, musty or moldy odors, peeling paint, warped floors, or visible mold. These signs point to water damage and possible structural issues—book a free consultation for an on-site damage assessment before costs escalate.
Can you handle mold remediation and make my basement safe?
Yes. We eliminate mold at the source, sanitize affected areas, and control moisture with thorough drying and dehumidification to protect indoor air quality and prevent future growth.
Will you waterproof my basement to prevent future problems?
Yes. During structural repair, we add foundation waterproofing, sealing, and drainage improvements to address root causes and reduce the risk of future leaks or floods.
Do you work with homeowners insurance and handle the claim?
We work directly with your adjuster, providing on-site assessment reports, photo documentation, and full restoration quotes to speed approvals. You focus on recovery while we manage paperwork and fast scheduling after approval.
How fast can you start, and how long does basement restoration take?
We prioritize rapid mitigation and can schedule quickly, especially after insurance approval. Timelines vary by damage, but most projects move from drying to finished in days to a few weeks.
