What is the hardest part of finishing a basement?

• <div><p>The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.</p></div>

Q: Is an extension less expensive than a loft conversion?

• <div><p>Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.</p></div>

Q: Do I need permits for flooded basement cleanup or repairs?

• <div><p>Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.</p></div>

Q: Is it less expensive to finish a basement or add an addition?

• <div><p>It&rsquo;s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is <b>$32,000</b> (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.</p></div>

Q: When should you not finish a basement?

• <div><p>Basements with persistent moisture problems or flooding shouldn&rsquo;t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. </p></div>

These guys are real professionals. The product is high quality, and the installers were great. They finished the entire house and basement in one day. And they cleaned up after each window.

Anders was an awesome find. Helped me work through a tedious kitchen remodel, from demo to floor, levelling, framing, and window installation. Always showed up and was thorough and self-directed.
