Q: What is the best drainage around a foundation?

• <div><p>Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it&rsquo;s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques&mdash;like soil gradation and gutter and leader installation&mdash;to resolve the underlying problem.</p></div>

Q: What methods are used for waterproofing basements or crawlspaces?

• <div><p>Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.</p></div>

Q: Is it worth it to clean a crawl space?

• <div><p>Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning&mdash;typically between $0.50 and $4 per square foot&mdash;is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.</p></div>

Q: What maintenance is needed after waterproofing or encapsulation?

• <div><p>Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.</p></div>

Q: What is the best type of insulation for crawl spaces?

• <div><p>Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.</p></div>

"Noticed a crack a few years ago, this year noticed it was bigger. Got 2 estimates. Not only was Locktight a better price, but the estimate was prompt, the guys worked fast and efficiently, nearly no disturbance to the area. Dug down (by hand!!) identified the broken elbow fitting in pipe, replaced it, waterproofed and sealed crack. Super professional. Would highly recommend."

Clay drain tile removal. FACT: With WNY being an older development in most areas, clay drain tile was used in the basements to lower the water table. Over time, clay deteriorates which leaves you with cracked, broken and defective drain tile. This leads to water backing up into your basement causing mold, mildew & damage to your foundation.

LockTight does it right by calling before we dig. We hand dig to protect your lawn, sidewalk, landscaping and underground utilities.
