Get matched with top basement waterproofing pros in Post Falls, ID

Q: How long should you wait after a new build to finish a basement?

• <div><p>You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.</p></div>

Q: Can you seal a foundation yourself?

• <div><p>While it&rsquo;s possible to seal a foundation yourself, it&rsquo;s not recommended, as it&rsquo;s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a <a href="https://www.angi.com/nearme/foundation-repair/">foundation repair professional near you</a> to see what the job will cost. </p></div>

Q: What are the hardest parts of finishing a basement?

• <div><p>Roughing in and connecting utilities are the hardest parts of finishing a basement, and they&rsquo;re the parts we typically don&rsquo;t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.</p></div>

Q: How hard is it to put a bathroom in a basement?

• <div><p>Installing a bathroom in a basement isn&rsquo;t a project for most homeowners. Many parts&mdash;plumbing, electricity, and carpentry&mdash;go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner&rsquo;s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. </p></div>

Q: Should I close my crawl space vents in winter?

• <div><p>In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.</p></div>

Jeff is an amazing craftsman. We have a 127-year-old house. We don’t think any real work has ever been done to the foundation. He came in when we had a big leak after a snowfall. His solution was innovative and effective. We ended up using it throughout the basement! Great work, Jeff!
