Get matched with top basement waterproofing pros in Pahoa, HI

Q: Should I pick a topical or a penetrating sealer for my project?

• <div><p>Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.</p></div>

Q: Does a basement need ventilation to reduce humidity?

• <div><p>Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.</p></div>

Q: Do I need a vapor barrier in my basement?

• <div><p>Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces. </p></div>

Q: What adds the most value to a basement?

• <div><p><a href="https://www.angi.com/articles/finished-vs-unfinished-basement.htm">Finishing an unfinished basement</a> adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.</p></div>

Q: Is a moisture or vapor barrier necessary?

• <div><p>A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.</p></div>
