Q: How long does foundation sealant last?

• <div><p>You&rsquo;ll need to reseal the foundation <b>every five to 10 years, </b>depending on the sealant you&rsquo;ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.</p></div>

Q: Are there downsides to waterproofing the basement?

• <div><p>Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it&rsquo;s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost. </p></div>

Q: What methods are used for foundation repair?

• <div><p>Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.</p></div>

Q: How many weep holes do you need?

• <div><p>It&rsquo;s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that&rsquo;s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.</p></div>

Q: Should you run a dehumidifier in the basement all the time?

• <div><p>No, your basement dehumidifier doesn&rsquo;t need to be on 24/7. While it&rsquo;s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.</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.
